Trophy Batteries are an Investment in Quality

“I think the Trophy Battery pack is probably the best
server rack LiFePO4 for the money on the market right now.”

Costs a little bit more than EG4, but lots of features and some of the best cells around. Just the terminals alone and the screen information are fantastic.

Very professional communication with that company as well.

I am thoroughly happy with my Trophy Batteries!  

I ordered these because they were the only quality battery on the market with built in heaters.  I live in PA and the batteries are in my garage.  I didn’t want to risk low temperatures preventing me from using my batteries. 

What I didn’t know was I was also buying some of the best customer support I have ever had!  These guys are all over it!  I even emailed them on a Sunday with a small question about the batteries I ordered… five minutes later my phone was ringing with my answer!  THAT is what counts these days.

They stand behind their product.  They are based on the East Coast, so I know I can call and speak with a knowledgeable person during business hours (or maybe even outside of business hours if there is an emergency).

Bottom line is this is the company you should choose.  Good old fashioned American pride and support.  That’s hard to come by these days.

                              Dave, Owner of Five 48V110C-1 Trophy Batteries

Trophy Battery offers premium batteries that are designed for long life. We use quality components and our build quality is excellent.

To back up our claims, we strive to provide the best “Customer-First” warranty in the battery industry.

Every Trophy Battery includes a 10-Year, Non-Prorated, Limited Warranty.

Some companies claim to offer 10-Year Warranties, but the warranty benefits taper off after an initial period which may be as short as one year, thus they are prorated warranties.

Our Limited Warranty is readily available; just click on “Warranty” in the above menu. We do not hide our warranty details.

Our warranty excludes physical damage, abuse, and diminished battery capacity. The capacity of all batteries diminishes over time, and this depends on how they are used and environmental conditions. Excessive heat is detrimental to batteries. 

If our batteries are properly used, and not abused, the remaining warranty may be transferred to a second owner after we determine that the battery has not been abused.

At this time, Trophy Battery is unique, as far as we know, as we use name-brand Lithium Ferrous Phosphate (LiFePO4) battery cells.

We currently use two top-tier battery cells, EVE Power and CATL. Both of these companies are widely recognized as quality manufacturers. 

CATL is the largest LiFePO4 cell manufacturer. Their battery cells are considered the best in the world.

Trophy Battery does not hide the brand of the cells that we use. Full specifications, Safety Test Results, and Material Safety Data Sheets are readily available in the Info section of this website.

After years of researching the Lithium Ferrous Phosphate battery industry and the batteries that were available, we decided to design/specify new batteries.

Our goal was to build batteries with every important feature and the highest quality components.

Specifically, the very best battery cells, laser-welded together for reliability, a top-quality Battery Management System (BMS), a User-Friendly Battery Status and History Display, quality internal battery cables, terminals, and a very strong steel case with proper internal bracing.

We selected a great battery company in China to build our batteries. Note that few LiFePO4 batteries are actually built from the ground up in the United States. Some batteries are assembled in the United States, but even this is rare.

Trophy Batteries are the highest quality, fullest-featured batteries that our high-volume manufacturer has ever built.

Only top-quality components are used in Trophy Batteries. The best name-brand battery cells, a great, programmable Battery Management System with current regulation, a strong steel case, and quality internal power cables.

All of these items contribute to a battery that is designed for long life.

The battery cells are laser-welded to the busbars that connect each battery cell to the next. This is for long-term reliability, as laser-welding does not loosen over time due to temperature changes or vibrations. With bolted-together batteries it is very easy to strip the threads causing a major problem. This will never happen with laser-welder cells.

Our top-quality Battery Management System (BMS) protects your battery. Over-charging, Over-Voltage, Under-Voltage, Excessive Discharge, Over-temperature (Six Sensors), and Under-temperature conditions are detected, recorded in memory, and corrected.

For example, when an excessive charging current is detected, the BMS takes action and regulates the current down to an acceptable level, then after an appropriate time restores normal charging if the current will not be excessive.

If the battery cells or the BMS gets too hot, corrective action is taken.

Trophy Batteries include battery heaters. Every state in the United States, including Florida, Texas, and Hawaii have areas where the temperature gets below freezing.

Most LiFePO4 batteries do not have battery heaters. These batteries cannot be charged when the battery cell temperatures get below freezing. If charging does take place, the battery will be destroyed.

The BMS in Trophy Batteries will detect near-freezing temperatures, then during charging, activate the four internal heaters to warm up the battery, then charging proceeds safely.

Many people may feel that they do not need battery heaters, but the risk of charging a freezing battery is too great.

The Trophy Battery heaters are a critical feature that allows us to offer a non-prorated 10-year Limited Warranty. Without this feature, the risk of damage to batteries is too great.

The following features are included in every Trophy Battery:

  • Name-Brand Battery Cells
  • Automatic Soft-Start to prevent damage to inverters
  • Laser-Welded Busbars to the Battery Cells
  • Programmable BMS with every battery protection feature
  • BMS with fault recording and memory
  • BMS records the number of battery cycles.
  • Automatic Charging Current Regulation
  • Over-Current Discharge Protection
  • Short Circuit Protection
  • DC Circuit Breaker for Redundant Over-Current Protection
  • Rugged Battery Terminals
  • Battery Status Display with History from BMS memory
  • BMS detection with automatic corrective action for adverse temperature conditions.
  • Battery Heaters (4) with Automatic Operation by BMS
  • Strong Steel Case with Rugged Internal Bracing
  • Each battery may be oriented in any position.
  • BMS is programmed to extend the life of the battery.
  • BMS protects the battery from over-temperature conditions
  • BMS protects itself from over-temperature conditions
  • Automatic Battery Cell Balancing to extend the life of the battery
  • Battery protected against accidental abuse by preventing discharge to 0% State of Charge.

Make no mistake, Trophy Batteries are not budget batteries where compromises are taken to achieve a low price

The Trophy Battery Battery Management System provides extensive protections for the battery cells and the battery overall.

Thus, primary protection for the battery cells is provided by the programmable Battery Management System.

For a redundant second layer of over-current protection,
a DC Circuit Breaker protects against over-discharge and over-charging.

For any battery that does not have a proper DC Circuit Breaker or uses an AC Circuit Breaker to save cost, an external DC Circuit Breaker or Special T-Class fuse should be installed to protect against excessive current or short circuit conditions.

Thus, Trophy Batteries, with their built-In DC Circuit Breakers provide extra protection and may prevent you from the extra cost of these external devices.

All Trophy Batteries include built-in battery heaters as these, along with our programmable BMS allow you to charge your batteries when the temperature is below freezing.

Other batteries without low-temperature protection are vastly inferior as their batteries can be damaged or destroyed by charging, just once, when the battery cells are at freezing temperatures.

Other batteries with low-temperature protection, but not heaters, are also inferior. During cold weather, you may need to charge your batteries, but the low-temperature protection will prevent you from doing so. Thus, a bad winter storm, such as that occurred in Texas in February 2020 may leave you in a crisis.

Trophy Batteries support both CAN and RS-485 communications. 

Some inverters may require you to use CAN or RS-485 communication protocols. 

To be very flexible, for now, and for the future, Trophy Batteries support both CAN and RS-485 communications.

Without this flexibility, if you want to upgrade your inverter or inverters in the future, you may find your battery to be incompatible with your new inverter(s).

Many batteries do not include both a CAN Port and RS-485 Ports.

Trophy Battery rates its batteries conservatively.

For example, our 48V220C-1 battery contains 32 CATL 120 Amp-Hour battery cells. Thus, the overall capacity of this battery may be rated by other companies as a 240 Amp-Hour battery.

But, we rate it at 220 Amp-Hours (AH) for a few reasons.

1. There are always some inherent losses in a battery. This reduces the effective capacity of the battery.

2. We extend the life of every trophy battery by not allowing full discharge to 0% state-of-charge (100% discharge).

When discharging a battery completely, the number of battery cycles is reduced, limiting the life of the battery.

We encourage our customers to not routinely discharge their battery below 20% (extending the life of your batteries).  We also prevent discharging below 5% state of charge. 

Thus, we do not count this 5% safety margin in our rated battery capacities.

3. If any LiFePO4 battery is ever discharged to a 0% state of charge, it should be recharged immediately to prevent damage to the battery. This may not be possible in many cases, especially with solar systems. Thus, discharging to 0% state-of-charge prematurely ages your battery.

Note: Using LiFePO4 batteries with a Solar system is ideal if you adequately size your battery system. Ideally, do not routinely discharge your battery below approximately 30% state-of-charge. This can greatly extend the life of your batteries.

Lithium Ferrous Phosphate (LiFePO4) batteries are far superior to Lead Acid batteries and are generally more economical long term.

Trophy Battery is a customer oriented company. Our Limited Warranty and our policies are always “Customer-First”.

This video clearly shows the superiority of Trophy Batteries. The two “Mystery Batteries” in front are our 48V100E-1 batteries. These use premium, brand name EVE Power Cells.

Note that the testing shows that our batteries outperform the other batteries.  On paper, the batteries should perform equally. But our batteries are very conservatively rated. You get more with a Trophy Battery.

Our batteries have a 10-Year, Non-Prorated, Warranty.

Here are Will Prowse’s comments about our batteries:

Trophy Battery: Internal Heaters And Non-Prorated Warranty





100AH Pack Is $.331 Per WH

This company is new to the scene, but they have some pretty nice batteries. Every pack comes with:

  • Large Terminals (EG4 and Jakiper have small terminals and cannot fit 2/0 cables)
  • High Quality DC Rated Circuit Breaker
  • Internal Heaters! This usually costs a lot of money, but these packs have this feature included
  • High quality, expensive cells from EVE or CATL. These are best in the industry
  • No questions asked 10 Year Warranty that actually transfers to the next owner if you sell it
  • 10-20 Year Design Life

I’ve actually been running these packs longer than EG4, and they work great. I have not had a single issue, and I prefer the trophy battery display and terminals. 

This is also the only server rack with low temperature internal heaters. If you are in a cold climate and need some serious energy storage, these are for you.

They have 3 sizes:
100Ah 48V Battery
220Ah 48V Battery
304Ah 48V Battery

Are Trophy Batteries Right for You?

After installing Solar Power, many are surprised that it shuts off during every electrical power grid outage. If you add Trophy Batteries to your system, you can continue producing electrical power when the grid power is down. Your Solar system may already support batteries, or you may have to install an inverter or inverters.

With Trophy Batteries, you may store excess solar power during the day, use it at night, or use it during cloudy days.

With an appropriately sized battery system, your stored electrical power can be used for critical loads when your Solar system is not producing enough power.

With a larger capacity Trophy Battery system, you can provide power for your entire home during the evenings. Of course, the amount of power you can store depends on the power output of your solar system and the capacity of your battery system.

Depending on your power company, you may be earning just a few cents for every KiloWatt of power you generate for them, but they charge you many times that amount for the power that you use from them.

With a Trophy Battery system, you can store your excess power in our batteries instead of sending it to your power company. Then you can use the power stored in your batteries instead of paying for power from your electrical company.

Backup or standby electrical generators are helpful. But, they have to be located outdoors, at least 10 feet from your home, due to the dangers of carbon monoxide. They are also noisy, require routine maintenance, and sometimes hard to start.

Natural gas-powered generators are not ideal for those in earthquake zones, as the gas company will shut off the natural gas supply immediately after an earthquake.

An alternative to a generator for electrical grid outages of a short to medium duration is a Trophy Battery system. You may place your batteries indoors or in a garage. They are fume-free, do not generate carbon monoxide, do not require routine maintenance, and start automatically without any interruption in your power.

The Trophy Batteries can be used just for critical loads or provide enough power for your entire home (which requires a high-capacity battery system).

In many areas, power outages are of short duration, typically under 8 hours or so.
In other areas, power outages may last for days. In this case, it is more practical just to power your critical loads, such as for refrigerators and freezers, and a few other items.

Powering critical loads is a great application for Trophy Batteries.

Depending on the length of your typical power outages, powering your critical loads is an easy task for an adequately sized Trophy Battery system. You can power a refrigerator and freezer for about two days with even our smallest Trophy Battery, if you have modern, energy-efficient appliances.

Note that you do not need a Solar system for this application. You may use your regular electrical grid power to charge your batteries.

A Trophy Battery System can help keep your critical refrigerators and freezers running.

Depending on the length of your typical power outages, powering your critical loads is an easy task for an adequately sized Trophy Battery system. 

Note that you do not need a Solar system for this application. You may use your regular electrical grid power to charge your batteries.

Time-of-Use or Peak electrical rates are becoming more common in the United States. These plans charge you more during peak times.

Some Time-of-Use plans have just two rates, peak and off-peak. During peak times, your electrical power rates are typically far more expensive than off-peak times.

Other plans have three tiers, peak, off-peak, and super-off-peak. The latter is typically late at night to early morning hours.

With a Trophy Battery system, you can charge your battery when the electricity is the cheapest. You can then use your stored electrical power during peak times instead of paying peak electrical rates to your power company.

For those living off-grid, you may be using Solar Power, a generator, or both.

By adding Trophy Batteries, you may increase its efficiency, extend its life, and use less fuel.

With a Trophy Battery system, you could use your generator to charge the batteries while the generator is running. Then, you can shut off your generator and use your batteries for power.

Generators are most efficient when you are running at high power. When your electrical load (demand) is low, your generator is less efficient, but still uses quite a lot of fuel to power a light load.

Thus, whenever the generator is running, use the electrical power from the generator to charge your batteries, then shut it off, and use battery power for your electrical needs. Of course, this is quieter and uses less fuel.

Some inverters have built-in features to manage this for you automatically. When your batteries are getting low, the inverter can start your generator. Then when the batteries are full, the inverter shuts off your generator.
