Material Safety Data

Why Choose the Trophy Battery 51.2V300E-3UL?

This model is ideal for users who need significantly more usable energy than 100Ah-class batteries, without sacrificing safety or longevity, while reducing the battery count.

Key advantages include:
  • High-capacity EVE Energy cells from a globally recognized manufacturer
  • 200 Amp BMS, allowing substantially higher output than competing batteries with 100A limits
  • Automatic Built-in battery heaters to warm a battery when necessary
  • Heavy-duty dual battery terminals for high-current connections
  • DC-rated circuit breaker for redundant protection

Many batteries in this capacity range are limited by undersized BMS systems. Trophy Battery designed this model to fully utilize its capacity.

Technical Information

Conservative Ratings for Long-Term Performance

Although each EVE Energy cell is rated at 102Ah, Trophy Battery conservatively rates this battery at 300Ah. Since there are 48 102Ah cells, the actual capacity is higher.

We do not count:
  • Inherent system losses
  • The final 5% of capacity reserved by the BMS to prevent damaging deep discharge

This approach delivers predictable, repeatable performance over the life of the battery, not short-term marketing numbers.

The 51.2V300E-3UL includes automatic internal battery heaters controlled by a fully programmable BMS.

  • Temperature sensors monitor cell conditions continuously
  • Heaters activate automatically during cold-weather charging
  • Charging resumes only when safe temperatures are reached
  • Heaters use charging power, never battery power

This protection is essential for cold climates and seasonal installations and is a key reason Trophy Battery can confidently offer a non-prorated 10-year warranty.

This battery includes multiple layers of protection:

  • Over-charge and over-discharge protection
  • Over-current and short-circuit protection
  • High- and low-temperature protection
  • Automatic cell balancing
  • Built-in DC circuit breaker for redundant safety

With a 200A BMS, this model supports higher inverter loads without artificial bottlenecks.

Up to 16 Trophy Battery 51.2V300E-3UL units can be connected in parallel to increase total capacity and current output.  Additional banks of up to 16 batteries can also be connected in parallel.

This makes the battery suitable for:
  • Whole-home backup systems
  • Larger solar storage arrays
  • Off-grid installations
  • High-demand inverter systems
