Trophy Batteries use Lithium Ferrous Phosphate (LiFePO4) cells. These LiFePO4 cells are safer than regular Lithium-Ion cells, as they never suffer from thermal runaway.

LiFePO4 cells have been thoroughly tested, and even when abused, will not catch fire.
The LiFePO4 battery cells will not start a fire due to an internal battery cell catching fire.

Lithium Ferrous Phosphate batteries use a limited number of battery cells. This is opposed to a Lithium-Ion battery of similar capacity, which employs hundreds of Lithium-Ion cells.

The individual battery cells are the heart of any battery. Invest in new, name-brand, quality cells, like EVE Power or CATL.

Trophy Batteries are in the 48 Volt Class of batteries, and supply, 51.2 Volts (nominal). Every 51.2 Volt Trophy Battery works with all 48V Class of Inverters.

The battery chemistry is Lithium Ferrous Phosphate which is very safe. There are 16 or 32 cells in each Trophy Battery. Some 48V batteries only have 15 cells; these batteries are less desirable.

For a top-quality battery, one must use top-quality battery cells.

Trophy Batteries only use brand name battery cells, EVE Power or
CATL (Contemporary Amperex Technology Co., Limited).

Many battery companies use lower-quality cells or do not specify which cells they use.
In fairness, they may use good cells, but with Trophy Battery, you know which brand cells are in your battery.

The cell to cell connections (bus bars) are also critical.

Trophy Batteries use bus bars (connectors) laser welded to the battery terminals.
Laser welded connections are always superior to other methods.

Some other batteries use wires/cables or bus bars that are bolted to each battery terminal. The problem with bolts is they can become loose, which then causes problems including arcing, diminished capacity, or battery failure.  Laser welded battery terminals are one of the signs of a superior battery.

Some will consider bolted terminals superior since a battery cell could theoretically be replaced easier if it fails. But, we believe this to be a fallacy. If a battery cell fails during the battery’s life, this indicates that top-quality cells were not used initially, or the BMS is not correctly balancing the cells. In addition, any replaced battery cell will not precisely match the other cells. Thus the concept of replacing a single battery cell in a battery is not practical.

Another important part is the Battery Management System (BMS). It is important for the BMS to be programmable. This enables the BMS operation to be customized to suit your needs by adjusting various parameters inside the battery BMS.

The battery terminals and internal cables are also important. The terminals must be rugged and designed to carry the battery current. The wires must be a suitable size to carry the rated current of the battery. Trophy Battery uses premium tinned copper, high-temperature (200C, 424F rated), silicone rubber insulated cables. These cables are proven to carry over 200 amps of current and are standard in every Trophy Battery.

A strong metal case with rigid internal bracing is essential. Our strong case with multiple internal braces (cross members) allows the Trophy Batteries to be safely placed vertically, with the front panel facing upwards.

Other batteries may not have such a robust case or lack strong internal bracing. Both are required to ensure that the cells are not damaged in various orientations.

Lithium Ferrous Phosphate (LiFePO4) batteries have proven chemistry; they are both very powerful and safe.

But, LIFePO4 batteries have one limitation. They must not be charged when the battery is at freezing temperatures.

Trophy Batteries have multiple temperature sensors strategically located in the battery. If the battery temperature gets close to freezing, then during charging, the battery heaters will come on to heat the battery to a safe temperature, then actual charging will proceed.

Our heaters will never drain your battery. They are powered by the charging current and are only used when the battery cells are close to freezing. As soon as the battery temperature has risen to a safe temperature, then the heaters are turned off, and normal charging resumes.

The heaters are located under the battery cells in direct contact with the battery cells. The heaters draw 100 Watts, thus provide 100 Watts of heat. 

The entire heating is controlled by our programmable BMS. It is fully automatic. When the battery is too cold, the heaters will protect your batteries from damage. Charging a frozen LiFePO4 battery cell will permanently harm it. With our heaters, you never have to worry this issue.

The batteries should be located in a relatively protected area, such as indoors, in a shed, or in a garage. They should not be located outdoors, exposed to the elements. 

During discharge, the batteries will generate some heat. If you are in a very cold environment, it is ideal to insulate the batteries from excessive cold. 

All Lithium Ferrous Phosphate batteries work best around room temperature. When very cold, the output power will be lower like all other batteries. Thus, insulating the batteries from extreme cold is a great idea. When the batteries return to normal temperatures, the batteries will return to their normal power output.

Most other batteries do not have internal heaters and a Battery Management System that will control the heaters.

The lack of heaters in other batteries is a problem. Please consider the following scenario.

In Texas, in February 2020, the ordinarily moderate weather turned freezing, and the electrical grid power failed in many locations.  Then Grid-tied solar systems without batteries shut off to protect the utility workers. This extended period of below-freezing weather caused many parts of the electrical grid in Texas to fail. The extended extreme cold also caused the natural gas system to fail, as the gas valves and infrastructure were not designed for such cold weather.

Thus, many people with solar systems found themselves without utility power, natural gas, and solar power for days, which was a significant crisis for many families.

If the homes with solar power also had backup battery systems, they would have continued using their solar power with one caveat. If using LiFePO4 chemistry, their backup battery would have to be kept warm (above freezing) to allow the solar system to charge the battery.

Typical backup battery systems with temperature sensors but no heaters would then stop charging. Thus their backup battery systems would quickly drain without the ability of their solar system to recharge their batteries. If they had batteries without proper temperature sensors, they were at risk of destroying their batteries if the solar system attempted to charge a frozen Lithium Iron Phosphate battery.

You may use Trophy Batteries to supplement your Solar System.

With an inverter that works with batteries, you will have several significant new capabilities.

  1. When your electrical grid is down, you will still generate electricity from your solar system to supply power to your house or your critical loads.
  2. You may store excess power from your solar system into your Trophy Battery or Batteries. With most inverters that support batteries, you can control how you charge your batteries.
  3. You can either
    (1) first charge your batteries, then power your home, or
    (2) first power your home and then charge your battery or batteries.
  4. Thus, during a grid-down situation, and when your solar system is not producing power, you may use your Trophy Battery system, in conjunction with an inverter that supports batteries, to provide power to your critical loads.

    Or, if you have enough battery power, usually using multiple batteries and one or more inverters, you may power your whole house.

  5. Your battery capacity and the state of charge in your batteries will determine how long you may power your house on the batteries.

You may use Trophy Batteries without a solar system.

  1. In this case, you use electrical grid power, or if you are off-grid, any other suitable electrical source with proper inverters, or LiFePO4 chargers, to charge your batteries.
  2. Then, with a suitable inverter or multiple inverters, you may power your critical loads or your entire home (depending on your installed battery capacity and state of charge).

    Powering your entire home requires a powerful battery system, typically with multiple Trophy Batteries and one or more suitable inverters.

  3. Therefore, the Trophy Battery System, along with a proper inverter or inverters, works as a backup generator to power your critical loads or your whole house.
    1. With proper inverter(s), the Trophy Battery system typically starts automatically, like a UPS (Uninterruptable Power System.) Compare this to the process of starting most generators, which may require some expertise.
    2. The Trophy Battery System is noise-free, unlike a generator.
    3. The Trophy Battery System does not emit dangerous Carbon Monoxide.
    4. The Trophy Battery System does not need to be placed at least 10 feet from your home, as generators must be, for safety.
    5. The Trophy Battery System does not require routine maintenance.
    6. The Trophy Battery System with proper inverter(s) can start reliably and instantly to provide backup power to your critical loads or your entire home.
      (Depending on battery capacity and state of charge of the battery system.)
    7. In earthquake-prone areas, the natural gas suppliers will immediately shut off the gas supply. Thus, a natural gas-powered generator is not desirable for earthquake-prone regions.
    8. The advantages of a safe, silent, reliable, backup power source cannot be over-emphasized.
    9. Note that most power outages are of limited duration.
      You may choose a small backup battery system to power critical loads for a short time, or a much larger system to power large loads, or critical loads for days at a time.

In some areas, electrical utilities charge substantially more for electricity at peak times.
Some then have lower off-peak rates, and some may have super-off-peak rates, usually in the middle of the night.

Time-of-Day, or Peak Rates, can make electricity very expensive when you need it most.

With a Trophy Battery system, along with suitable inverters, you can charge your batteries when the electricity is the cheapest, then use battery power during times when electricity is expensive

An investment in a Trophy Battery system can help you avoid the high cost of electricity for years.

Lithium Ferrous Phosphate batteries have a much longer lifespan if they are not routinely discharged to 0%.

Trophy Batteries have a premium, programmable BMS, which has been factory programmed to prevent accidental abuse of the battery, which would or could significantly diminish the life of your battery. Thus, if you perform capacity testing of a Trophy Battery, you will not see the battery’s full capacity. But you will see your Trophy Battery’s rated capaciity (Initially, as battery capaciity diminishes over time). But, you may change the factory default settings of the battery to perform a capacity test.

However, since it is good management to never fully discharge the battery we recommend using the factory default BMS settings for maximum discharge. 

Just as you should never fully discharge Lead-Acid batteries, we recommend that you not fully discharge your Trophy Battery or any other Lithium Ferrous Phosphate battery. The small amount of extra power is not worth diminishing your battery over time. Trophy Batteries come pre-programmed to prevent discharge to 0%.

Trophy Battery provides conservative capacity ratings for all of its batteries. If another company built a battery with the same components, they might rate it higher. Providing conservative capacity ratings is a little complex, so we offer the following information.

Top Tier battery cell manufacturers provide very conservative battery ratings. For example, a brand new EVE Power cell rated at 105 AH (Ampere Hours or Amp Hours) will initially provide around 110 AH. 

All brand new, adequately stored batteries will initially provide more capacity than after being used for a while. This is normal and expected. For top-tier batteries, this capacity drop-off will be minimal.

Then over time, the capacity will slowly diminish, provided one uses proper battery management techniques. We cover these techniques in another section, but briefly, they are:

  • Avoid elevated temperatures over around 100F (37.8C), with room temperature a great goal.
  • Do not fully discharge the batteries.
  • Properly size your battery system so that you do not routinely discharge your battery below 50% state of charge. (But, when necessary, you may discharge your battery to a 20% state of charge ot lower.)
  • Charge and discharge at no more current than is appropriate for your battery.
    A simple goal is 50% of your batteries rating. For 220 AH, no more than 110 AH.

The huge CATL battery that Trophy Battery offers contains 32 120 AH cells. The 120 AH is CATL’s rating for the battery. Initially, they will test higher.

Then our Trophy Batteries BMS is factory programmed to prevent damage from discharging below 5%. Also, there are minor inherent losses, as the BMS uses a little power during operation.

A new, huge CATL battery was tested to 222 Amp-Hours (AH) with the BMS programmed to factory defaults. So we rate this battery at 220 AH. Other companies may rate it higher, as it does use two conservatively rated 120 AH cells, thus 240 AH in total.

While other companies may rate this huge battery at 240 Amp-Hours (AH), since it uses 32 120 AH cells in a 16s2p configuration, we only call it a 220 AH battery. One reason is that we want your battery to last, so we protect your battery from discharging below a 5% state of charge (unless you change the BMS programming).

To provide more details, due to inherent losses, the 240 AH battery, without the BMS protecting it from deep discharges, would rate around 234.6 AH. Then reserving 5% gives 222 AH. So we rate it at 220 AH to be conservative.

Trophy Battery rates the 16 cell CATL battery, with 16 120 AH cells, at 110 AH.

The EVE Power celled battery uses 16 EVE conservatively rated 105 AH cells. These cells, when new, test at slightly over 110 AH. We rate this battery at 100 AH.

Only top-quality materials are in Trophy Batteries. The cells are name brand. The Battery Management Systems (BMS’s) are top-quality programmable devices. They all have an LCD panel that shows the overall status of the battery and detailed information on each battery cell. The 51.2V300E-3UL using 16s3p configuration thus displays information on each triplet of 102 AH Cells in parallel.

Most importantly, every individual battery cell is individually tested before constructing the battery. Then the cells are balanced together. This lengthy and thorough testing ensures that a Trophy Battery will have a long life. This expensive testing and balancing of the cells contribute to the high quality of Trophy Batteries.

The premium Trophy Battery BMS keeps the cells in balance. No separate manual balancing of the cells is necessary. The LCD control panel will display the cell voltages so you can see that the cells are balanced. Typically, the cells will be within a few millivolts during the life of the battery.

Every Trophy Battery uses Laser Welded battery cell connections. This is the highest quality and most reliable way to connect the 16 or 48 battery cells. Alternative methods, including busbars bolted to battery cells, are not as reliable.

The battery case is heavy steel, and there are strong cross members to ensure the strength and rigidity of the battery case.

“Battery Cycle Life” is a term used to denote the number of times a battery may be charged and discharged, with the battery capacity remaining at 80% or higher. Note, after this number of cycles, the battery is still very useable.

But, please be very cautious when comparing Battery Cycle Life values you see in marketing materials.

Lithium Ferrous Phosphate batteries can have a long life and an exceptionally long life under the right conditions.

Here is an example. Over the life of a battery, if it was charged to 100%, deeply discharged, with high ambient temperatures, then the number of Battery Cycles will be low.

If a battery is charged to around 95%, then discharged to only 50% on most charge-discharge cycles, and kept at reasonable temperatures, the battery will last an extraordinary number of cycles.

Thus, to make an informed decision a claim of very high Battery Cycles, one needs to know the starting state of charge, the rate of charge, the depth of discharge, the rate of discharge, the ambient temperature of the tests, and the storage conditions of the battery before performing the tests.

Marketing Materials rarely provide all of these details.

A manufacturer’s battery specification may list only 2,500 to 3,500 under demanding conditions, then show charts showing alternative conditions where the “Battery Cycles” can reach 10,000 or more.

Note: A claim of 7,000 battery cycles may be perfectly valid, provided one uses standard practices to help ensure the long life of the battery. Under more demanding conditions, the number of cycles may be much lower.

So, the same battery, rated under differing conditions, may be rated at 3,000 to 10,000 cycles or more. Thus, please be cautious when you read claims of high battery cycles.

It is important to note that when using batteries in solar systems, the nature of the charge/discharge cycle typically results in a high number of battery cycles.

The same applies when using batteries in Uninterruptable Power System for one’s home or another facility. This battery application, proving power on-demand, also typically results in extended battery life.

Batteries stored at high temperatures, charged to 100%, then discharged to a low level every day will not last as long as the same battery used under more favorable conditions.

To ensure that your battery lasts a long time:

Keep the battery relatively cool. Temperatures in the 90s (F) are acceptable, room temperature is even better, but much over 100F diminishes the battery’s life.

Purchase enough battery capacity, measured in Amp-Hours (AH) or Watt-Hours, so that you are not deeply discharging your battery daily. You may purchase multiple batteries and connect them in parallel or purchase larger capacity batteries.

Ideally, charge your battery to only 98% or so and discharge your battery (generally) to only around 50%. Under these conditions, each charge-discharge cycle does not even count as a Battery Cycle.

Note: Most car manufacturers never discharge their batteries below a certain level in their battery-powered and hybrid vehicles. They are using the practice of lightly discharging the battery to extend the life of the batteries. This enables their batteries to be used every day for many years.

For emergencies, when the electrical grid is down, or you expect it to fail for some reason, it is perfectly acceptable to charge your battery to 100% and then discharge it to 20% during the outage. This technique will count as one “Battery Cycle” out of the many thousands of cycles available in the battery.

Batteries fall into general classes, such as 12 Volts, 24 Volts, or 48 Volts.

Most cars use a 12 Volt class battery, but the voltage varies, as it does in all batteries. When fully charged, its voltage is higher than 12 volts, and the voltage lowers during discharge. The nominal voltage for a lead-acid car battery cell is usually 2.2 volts and contains six cells, so the nominal voltage for a 12-volt car battery is 13.2 volts. But, it is in the 12-volt battery class.

Lithium Ferrous Phosphate batteries use cells that have a nominal voltage of 3.2 volts.
Using 15 of these cells creates a battery with a nominal voltage of 48 Volts. Some battery manufacturers build batteries with only 15 cells.

Batteries with 16 cells are better than batteries with only 15 cells. A 16 cell battery packs more power than a 15 cell battery.

Trophy Batteries always contain sixteen (16) 3.2 Volt nominal cells and thus are rated at 51.2 Volts. But our 51.2 Volt batteries are still classed as 48 Volt batteries. Therefore 48 Volt rated inverters are a perfect match.

Volts are a measure of ¨Electrical Pressure¨. The higher the voltage, the higher the ¨Electrical Pressure¨.  An analogy is a water hose. Volts are like the water pressure in a hose.

Amps (Amperes) are a measure of the flow of electricity, which is called electrical current.
The higher the current, the higher the amps. The electrical current is like the flow of water in a hose.

Amp-Hours (AH) is a measure of power in a battery. A 100 Amp-Hour battery is more powerful than a 50 Amp-Hour Battery.

This section is a simplistic discussion of Amp-Hours as battery chemistry, and other factors affect the power output. Still, generally, a 100 Amp-Hour (AH) battery can output 100 amps for 1 hour, or 50 amps over 2 hours, or 20 amps over 5 hours.

Please note the other factors mean that this simple math does not always hold up in actual practice but gives a general guideline of how this works.

Watts are a measure of “Electrical Power” or Energy. Watts are calculated by multiplying Volts times Amps. Watts are a familiar concept to many, as one may be familiar with an old fashion 100 Watt light bulb, which uses (approximately) 100 watts of electrical current. You may also be familiar with a portable room heater rated at 1,500 watts.

Watts are also helpful as many appliances are rated in Watts. Thus, the number of watts that your appliances and other devices use may be used to size a battery system.

A battery with 48 Volts nominal (15 cells) that can output 100 amps is a 4,800 Watt -Hourbattery.

A battery with 51.2 Volts nominal that can output 100 amps is a 5,120 Watt-Hour battery.

The 51.2-volt battery is more powerful, thus more desirable.

Watt-Hours are a measure of a battery’s power or energy. Like Amp-Hours, Watt-Hours measure how many watts of energy a battery can output over time.

A 5,120 Watt-Hour battery can output 5,120 Watts for 1 hour or 512 watts over 10 hours. As before, other factors affect the battery’s energy, so these values are general guidelines.20

Charging any Lithium Ferrous Phosphate battery requires a proper Lithium Ferrous Phosphate charger or one or more inverters that support Lithium Ferrous Phosphate batteries.

Use only DC (Direct Current) of the proper voltage and current for charging these batteries. You must use a proper LiFePO4 charger or inverter rated for 48 Volt batteries.

Never use any voltage of AC (Alternating Current, standard household current) to directly charge our batteries. You must use an appropriate charger or inverter to charge the batteries.

Never use a vehicle’s alternator to charge our batteries. The alternator will probably be the wrong voltage and will not follow proper charging techniques.

Using a value of 30% or higher will extend the life of your battery. If you use a higher value, you can reduce this in Menu Item 21, to 5% when you have emergency situations and you need all of the battery power that you have available. After the emergency, restore this value to your desired setting.

Detailed Discussion

Hybrid Inverters, Solar Charge Controller, and Battery Chargers typically have charging profiles.

These typically can be customized for different types of batteries and battery chemistries.

A charge profile for a Lead-Acid battery will be different than a Lithium Ferrous Phosphate battery like all Trophy Batteries.

Battery Charging Profiles have different names for the same concepts.

Constant Current / Bulk Charging

This is where the charger outputs a specific amount of current to the battery. The charger may be more sophisticated and ramp up to the specified constant current during this initial phase of battery charging.

For Trophy Batteries, the most desirable charging current is up to 0.5 (or ½) C. C is the AH (Amp-Hour) rating of the battery:

48V100E-1, 100 AH (Amp-Hours), C=100 Amps, Battery Cell=105 AH, 0.5C = 52.5 amps
48V110C-1, 110 AH (Amp-Hours), C=110 Amps, Battery Cell=120 AH, 0.5C = 60 amps
48V220C-1, 220 AH (Amp-Hours), C=220 Amps, Battery Cells=240 AH, 0.5C = 120 amps
This battery has 32 cells, so there are two 120 AH cells in parallel thus 240 Amp-Hours instead of 120.

Note, it is perfectly acceptable to use a lower charging rate; you do not have to charge at 0.5C.

It is also perfectly acceptable to use a higher charging rate, above 0.5C, but you should never exceed the full C value. It is desirable, on a routine basis, to stay below the full C value. For an extended battery life, up to 0.5C charging is desirable.

The maximum charging amps is also limited by the circuit breaker in each battery:

48V100E-1 has a 100 Amp circuit breaker
48V110C-1 has a 100 Amp circuit breaker
48V220C-1 has a 200 Amp circuit breaker

If you have multiple batteries in parallel, the desired charging rates can be multiplied by the number of batteries.

Note, with large and very large battery banks, you may not be able to achieve the desired 0.5C times the number of batteries, charging rate. This is perfectly acceptable. On days where you can charge your batteries more due to more solar power, then you will build up the charge in your batteries over time.


The most desirable charging current, for the maximum life of your batteries, is to routinely charge at any number of amps up to the following.

48V100E-1: Recommended up to 52.5 amps, maximum charging rate 100 amps
48V110C-1: Recommended up to 60 amps, maximum charging rate 100 amps
48V220C-1: Recommended up to 120 amps, maximum charging rate 200 amps

Constant Voltage/Charging Voltage/Absorption

After the Bulk or Constant Current stage of charging, sophisticated chargers or inverters convert to a Constant Voltage method of finishing the charging of the battery.
We recommend a setting of 56.0 Volts to 56.8 Volts for this phase of charging.

Some will use the term Absorption for the Constant Voltage charging stage, for example, Sol Ark, others will have a separate battery charging phase of Absorption.

Since Lithium Ferrous Phosphate batteries do not need an absorption phase, just set Absorption to the same value that you set for the Constant Current stage, 56.0 Volts to 56.8 Volts.


Lead-Acid batteries in use for energy storage may need an equalization stage. Trophy Batteries never need equalization.

If you can disable the equalization stage, or set the duration to zero, please do so.
If you cannot, then set the equalization state to the same value, 56.0 Volts to 56.8 Volts.

Please feel free to call us for assistance at 803-380-6211.



We are conservative in our battery ratings. We want to under-promise and over-deliver.

Our batteries with EVE Power cells use 105 Amp-Hour prismatic cells. This 105 Amp-Hour rating is also conservative as these cells typically output around 110 Amp-Hours initially.
We rate this battery as 100 Amp-Hours.

Our batteries with CATL cells use 120 Amp-Hour prismatic cells.  We have two battery models with these CATL cells.

The first uses 16 of the CATL 120 AH cells. We rate this battery at 110 Amp-Hours to be conservative.

The second uses 32 of the CATL 120 AH cells. We rate this battery at 220 Amp-Hours.

Note: it is perfectly normal for a battery to diminish in Amp-Hour and Watt-Hour capacity over time as the cell ages. By following our battery guidelines, you will help ensure your battery capacity.

Note that all batteries age, and this is called “Calendar Aging.” Thus you can expect your battery capacity to be lower over time.


You may connect a Trophy Battery in parallel with another of the same specific model. This is called “Paralleling” of the batteries.

When one connects two batteries (of the same specific model), the power of the battery doubles, the voltage stays the same, but the number of Amp-Hours and the number of Watt-Hours doubles.

You may connect up to 16 of the same model of Trophy Batteries together to create a battery system that is capable of providing much greater power for your applications.

You may connect multiple 48V100E-1 batteries to more of the same model battery. All of the batteries must be the same model or the 48V110C-1.

The 48V110C-1 may be connected to more of the same model battery.

And our 48V100E-1 battery or batteries may be connected in parallel with 48V110C-1 battery or batteries. In this case, the like batteries may be connected via communication cables using the RS-485 Ports. But do not plug communications cables from one type of battery to another.

The 48V220C-1 battery may be connected to more of the same model battery,
and it may be connected in parallel with our 48V220E-1 battery
(but do not connect communication cables between the two different battery types.)

Do not connect one or more 48V100E-1 or 48V110C-1 batteries in parallel or series with 48V220C-1 or 48V220E-1 batteries.

To be more general, do not connect multiple batteries of different capacities, except for the combinations specified above.

If you wish to connect other batteries to our batteries, please call us at 803-380-6211 and we will advise you.

These restrictions are for safety. If you use different battery models, the current imbalance may cause a safety hazard. In addition, connecting a more powerful battery to a less powerful battery can damage the batteries. Any damage caused by connecting different types of batteries together is not covered by our warranty.

Never connect the batteries in series. This is where the minus (-) of one battery is connected to another battery’s plus (+). This series connection increases the voltage of a battery system. Doing so will void all warranties.

The following graphic shows a very popular and highly effective way to cable mulltiple batteies together. In the image on the right, the batteries are connected to busbars or battery distribution blocks using separate equal length cable runs from the minus terminal of each battery to the minus busbar, and a separate equal length cable runs from the plus terminal of each battery to the plus busbar.

If you need to connect only a few batteries together in paralled, there is another way to do so.
The following technique works when the battery to battey cables are oversized, and when three to six batteries are in one bank. 

Before, using this alternative technique, please call us at 803-380-6211 so that we can advise you personally. We will advise you on cable sizes and explain this technique in detail. We will also discuss your future plans to expand your battery system.

This technique enables multiple batteries to be connected in parallel, like the image with an X above, but an extra cable is added to ensure that charging and discharging of the batteries are better balanced.

Two extra cables are required to help balance the loads.

      One from the Positive terminal of one battery at one end of the bank,
      to the Positive terminal at the other end of the bank.

      And another cable connecting the negative terminals in the same manner.


It is recommended that you:

Connect equal length cables from the inverter or inverters to the positive terminal at one end of the bank of batteries,

And connect the negative cable to the negative termnal at the other end of the bank of batteries. 

This is called Diagonal Cabling and it is another technique to balance the load and balance the charging of the batteries.



The life of a car lead-acid battery is significantly reduced when it is deeply discharged. The typical figure quoted is that a standard car lead-acid battery should not be discharged beyond 50%. But, this is a myth as this is true only under specific conditions. If you wish to have long life out of a car’s lead-acid battery, one should not discharge it to 50%. There are actual “Deep Cycle” batteries that are different and can tolerate greater discharges.

Lithium Ferrous Phosphate (LiFePO4) is the chemistry in the Trophy Battery’s cells. These batteries can be discharged to a deeper level, such as to a 20% charge without damaging the cells.

While no damage will be caused by discharging a Lithium Ferrous Phosphate battery to a 20% state of charge, it is not a great idea to do this daily.

Lithium Ferrous Phosphate cells and batteries can have a long life, which is called Cycle Life. This is the number of times a battery can be charged and discharged while maintaining 80% of its original capacity.

One can significantly extend the life of Lithium Ferrous Phosphate batteries by following these guidelines.

a. Keep the battery near room temperature. Around 77F or 25C is an ideal temperature.

It is acceptable to allow the battery to reach around 100F or 37.8C or slightly higher. But, it is advisable to keep them cooler.

If you are comfortable, then the battery will be “comfortable” and have a longer life.

Higher temperatures will reduce the life of the battery.

Colder temperatures reduce the power output of a battery. As the temperature gets colder, the power output gets lower, and the ability to charge the battery diminishes greatly.

Lithium Ferrous Phosphate is great battery chemistry for many reasons, including safety. But, one cannot charge this type of battery if any cell is at or below 32F or 0C, which will damage the battery.

All Trophy Batteries have built-in heaters. This heater diverts the charging current to the battery heaters until the battery is warm enough to be charged without damage.

Many parts of the United States and other countries get below freezing at times. An example was South Texas in February 2020. Even Florida can get below freezing at times. Mountainous areas of Hawaii can get very cold.

b. Limit the depth of discharge. Every Lithium Ferrous Phosphate battery can be discharged to 20% on occasion. But, regularly limiting the depth of discharge will significantly extend the battery’s life.

If one over-sizes the battery system so that it is only discharged to about 50% or greater on a routine basis, then the battery life will be significantly extended. When the battery is not deeply discharged to 20%, then each charge-discharge cycle will not count as one “Cycle” of the battery.

The less you discharge the battery, the longer the life of the battery.

c. Limit charging. While one can fully charge a battery to 100% State of Charge every day, it is far superior only to charge the battery to around 98% each day. This technique also increases the life of the battery.

d. Use Moderate Charging and Discharging Currents

Batteries work best when charged and discharged at appropriate amperage for the size of the battery.

Good charging and discharging rates for a 100 Amp-Hour battery are 50 amps.

The batteries are capable of higher rates for both, but these moderate rates extend the battery’s life.

For a 110 Amp-Hour battery, the best rates are around 55 Amps.

For a 220 Amp-Hour battery, the best rates are around 110 Amps.

These are approximate recommendations; it is not necessary to always charge or discharge at precisely these rates.

When considering buying a battery system, it is best to consider your power needs.

The following information is very general in nature; your actual needs may be much more or much less. Your actual usage will vary, your battery run time will vary.  Our calculations may not apply to your specific situation.

We recommend considering the devices you want to power, their wattage, and how long they have to run during a power outage.

Your “Critical Loads” are the devices that you consider essential. These typically include refrigerators and freezers, television, and some lighting. Depending on your climate, you may need to power a furnace.

If you have a modern refrigerator and freezer, these do not use much electrical power. They may only use 100 watts. And it is unlikely that they run 24/hours a day.
Thus, 200 watts, running for an average of 8 hours a day, is only 1,600 Watt-Hours a day.
Then powering a modern television may only use 70 watts or so, and you may have it on for 12 hours a day, thus 840 Watt-Hours a day.

If you use LED lighting (and you should), each light on average is only 10 watts. If you have on ten lights, for 8 hours a day, this is only 80 watts-Hours.

A gas-powered forced air furnace motor may use 600 watts (more when starting), and run only 10 hours a day, thus 6,000 watts-hours.

The above are just the basics for keeping your food safe and connected to the rest of the world via television.

With the above level of very Spartan living, without including the furnace, you might need 1,680 watts-hours per day.

A 5,120 Watt-Hour (conservatively rated) battery, if you discharge it to 20%, gives you about 4,096 watts-hours.

With every Trophy Battery, we lower our Watt-Hour rating since we program your BMS to cut-off at 5% state of charge to protect your battery and lengthen its life. The actual capacity of the battery is greater, but we do not count the last 5%. 

Many inverters are 85% or higher in efficiency. The 4,096 x 85% = 3,481.6 Watt-Hours.

So, with only one 100 AH (Amp-Hour, 5,120 Watt-Hour battery, you can run the above critical loads (only) for about two days.

But, adding in a gas-fired forced-air furnace might add 6,000 Watt-Hours for a total of 7,680 Watt-Hours a day. In this case, the same battery may power your critical loads for around 10.8 hours.

If you add more batteries and run them in parallel, the Watt-Hours provided by your Battery System will increase.

Using this exact scenario, counting for not discharging below 20% and 85% inverter efficiency, with two batteries, your run times double, with three, your run times triple.


Many people may wish to purchase multiple batteries, especially in areas with frequent power outages, time-of-day electrical rates, areas prone to natural disasters, or those preparing for major electrical grid failures.

Also, many people will want to use more power. Electrical Water Heaters and Stoves/Ovens use a lot of energy, as do Air Conditioning systems.

A Trophy Battery system with multiple batteries can be very powerful.

For example, our 220 AH (Amp-Hour) battery provides 11,264 Watt-Hours. Adjusting for discharging to 20% is 9,011 Watt-Hours. Adjusted for 85% inverter efficiency is 7,659 Watt-Hours. Multiplying by 16, since one Trophy Battery system can consist of up to 16 batteries is 122,552 Watt-Hours or 122.5 KiloWatt-Hours.

You may review your electrical bill to determine how many KiloWatt-Hours you use a month, then calculate your daily usage, or your statement may show the average daily usage.

Another advantage of a multiple battery system is that the available current for your inverter(s) increases.

For a single 48V100E-1 battery, the charge and discharge current should be kept around 50 amps, but it can go higher up to 100 amps.

For a single 48V110C-1 battery, the charge and discharge current should be kept around 55amps, but it can go higher up to 110 amps.

For a single 48V220C-1 battery, the charge and discharge current should be kept around 110 amps, but it can go higher up to 200 amps.

By adding additional batteries, these current values are increased (multiplied by the number of batteries).

Note, if you are going to charge your batteries from a Solar Power system, size your system to keep your batteries charged. A small Solar Power System will not be suitable for a very large battery system.

If you use your batteries for time-of-day rate avoidance, your electrical system may be powerful enough to keep your batteries charged. Note that you will want to charge your battery when the lowest possible electrical rates are in effect.

The same applies if using a Trophy Battery system as an Uninterruptable Power System for your home. You typically use the electrical grid to charge your batteries. But, if you are off-grid, you may use a generator or Solar Power to charge your batteries. In this case, your Trophy Battery system operates like a noiseless, fumeless generator without carbon monoxide hazards.

Please note that this section is general in nature and cannot be relied upon to apply in your case.

Please note that a Trophy Battery system costs just a fraction of many other battery systems. Examples are Tesla Powerwalls, Sonon, Enphase, and Generac.

Trophy Battery uses only top-quality, new, name-brand battery cells.

We use sixteen (16) 105 Amp-Hour rated EVE Power cells in our very popular 100 Amp-Hour rated, 5,120 Watt-Hour Battery.

We use sixteen (16) 120 Amp-Hour rated CATL cells in our popular 110 Amp-Hour rated, 5,632  Watt-Hour Battery.

We use thirty-two (32) 120 Amp-Hour rated CATL cells in our huge capacity 220 Amp-Hour rated, 11,264 Watt-Hour Battery. These cells are in a 16s2p configuration.

There are many types of inverters and solar chargers.

Microinverters are popular. These generally work with individual solar panels and produce 240 Volt AC electricity for your home.

Hybrid Inverters such as the Growatt SPF5000ES are very useful. They are very flexible all-in-one devices, as they accept power from the grid, solar power, charge your battery system, and use battery power when appropriate. They include a solar inverter, a solar battery charger, and a battery-powered inverter.

Many regular inverters work well with batteries; others may not.

All Trophy Batteries pass the UN38.3 testing, which ensures that the batteries are safe for shipping.

UN38.3 is the third section 38.3 of the United Nations Dangerous Goods Transport Experiment and Standards Manual (for safe air transportation of lithium batteries). The purpose is to ensure the safety of lithium batteries during transportation.

Both the CATL 120 AH and the EVE Power 105 AH battery cells pass these rigorous tests.

T.1 Altitude simulation
T.2 Thermal test
T.3 Vibration
T.4 Shock
T.5 External short circuit
T.6 Impact/Crush
T.7 Overcharge
T.8 Forced discharge

To be very frank, we wanted to sell these ultra-premium batteries for less. Even though we had to raise our prices, we still feel that our battery prices are very competitive as we offer name-brand cells, top-quality construction, superior features, and full support in the United States. We design and build Trophy Batteries to last.

Most everyone realizes that prices are rising due to inflation. In 2021, fuel prices, food prices, housing prices, and shipping prices have risen significantly.

Prices of batteries are rising due to material costs rising.

Shipping costs have gone up over 1000%, 10 times.

The value of the US Dollar is diminishing, which affects the price of batteries and other merchandise.

Our batteries are made to our specifications and quality standards by a top-quality battery manufacturing company in China.

China is also experiencing inflation. The price of Lithium Ferrous Phosphate battery cells rose over 70% during 2020.

Shipping costs and shipping delays are also a problem.
We strive to keep our batteries in stock, and we order our batteries in advance.

We want to do our best to keep them in stock, but we expect some out-of-stock situations in 2022.

Due to rising costs, including substantial shipping costs, we may have to raise our prices in the future.

We do not know when this global problem will go away. In November 2021, we noticed an extraordinary number of tractor-trailer trucks on the interstate highways, so things seem to be improving. We are also now using other ports that are less congested.

Trophy Battery will keep its prices as low as possible, but please understand that our prices may change over time.

If we are out of stock, then you may preorder the batteries which reserves the batteries for you.
Or you may join our Notification Waitlist. We will attempt to notify you of any delays, but please understand shipping delays due to port congestion are beyond our control.

Our Notification Waitlist enables us to communicate with you. There is no cost or obligation to join our Notificaion Waitlist. Please note that paid preorders have priority over those on the notification only wait list. We will strive to keep you informed.

Trophy Battery products must not be used in any life-support or life-critical applications.

You may use a Trophy Battery to power some medical devices if the device is not life-support or life critical.

Trophy Batteries must not be used for any critical application, such as in the nuclear power industries, or in any application where the loss of power would cause a critical situation.

All batteries have inherent limitations.
Battery power is inherently limited and can only provide power for a limited time.
Batteries can fail.

Trophy Battery LLC voids all warranties if its products are used in any life-support, or life-critical application, or used in the nuclear power industries.

Due to the large amount of power in our batteries, you need to use a licensed electrician to connect your batteries to your inverter or inverters.

You must use protective gear, insulated gloves, proper eye protection, and insulated tools.

If you choose to install the batteries yourself, please have a licensed electrician check your work. During installation, ensure that the Circuit Breaker is in the off position at all times. Also, you should measure the terminals with a voltmeter to ensure that no current is flowing before you perform the installation or any work around the battery or batteries.

Every one of our batteries is heavy, weighing from 100 to 242 pounds., even more when in their shipping cases. We recommend getting assistance when handling the batteries.

You must use the proper type and size of electrical power cables to avoid fires.

  1. When connecting each battery to busbars, use equal length, adequately sized cables.
  2. When using multiple batteries in parallel, you will use cables from the busbar to the inverter DC connection. These must be larger size cables than the cables going from your batteries to the busbar.
  3. Use power cables suitable for high currents. If you are using multiple batteries in parallel, your maximum current rating for the cables going to your inverter is a multiple of the current rating for each battery.
  4. Use proper, heavy-duty, UL Listed battery lugs and proper tools to attach lugs to your cables or purchase quality battery cables.
  5. Please feel to check with us for the proper size cables to use.

    Trophy Battery cannot be held liable for improper installation or handling of the battery, including all injuries or deaths.

    Trophy Battery cannot be held liable for your installation and any problems that were not caused directly by the battery itself and not the installation or advice we have provided.

Trophy Battery strives to keep batteries in stock at all times, but due to extensive shipping delays, keeping every battery in stock at all times is not possible.

If we have the battery or batteries you want in stock, you may order them.
If not, you may decide on another battery, preorder your battery, or join our Notification Waitlist.

If we are out of stock, you may preorder the battery, which reserves the battery for you. We will process all preorders in the order that they are received. You will be added to our High Priority Preorder List.

We cannot provide the exact time our next batch of batteries will arrive, but we will strive to keep you informed. Shipping delays are beyond our control. 

If you wish, we will add you to our Notification Waitlist for your battery or batteries. This list does not obligate you to purchase the battery.

We fulfill all preorders before those on the waiting list. We will contact those on the waiting list when we are close to receiving a new batch of batteries.  We will send you an email or call you.
At this time, you may order batteries if you wish.

If you are on the waiting list, you may change to a preorder at any time to reserve your battery or batteries.

It is necessary to use the same model battery when connecting batteries in parallel.
This is for safety reasons, as mismatched batteries may not charge or discharge equally.

Thus, whenever possible, we recommend that you purchase all of the batteries that you wish to use at one time.

Note that multiple batteries are frequently used in parallel to provide an adequate amount of current to your inverters. It is also best to size your battery system to avoid frequent  discharges to a 20% state of charge. 

Since all high-capacity, heavy, Lithium Ferrous Phosphate batteries must be shipped by surface freight only, we have a limited delivery area.

Regretfully, we are limited to shipping to the lower 48 United States only at this time. Thus, we are unable to ship to Alaska and Hawaii at this time.

In the future, we may be able to add other North American countries. 

To Turn On the battery, press gently on the recessed Reset Button with a ball-point pen or similar object.

To Turn Off the battery, press and hold the recessed Reset Button for three seconds or so until the four SOC LEDs start blinking, then release. The battery will then shut down in a few seconds.

All Trophy Batteries use M8 size bolts on the battery terminals. These are superior to the typical M6 size terminals on other batteries.

You may use up to a 3/8″ battery cable lug, but a 5/16″ cable lug provides more contact area with the battery terminals.
