This Battery Talks Directly to Your Inverter for Smarter Power

The INV version connects with EG4 and Victron inverters using CANBus and RS485 protocols. This two-way communication lets your system charge and discharge more efficiently, protecting your battery and squeezing better performance out of every kilowatt-hour you store.

Cold Weather Will Never Kill Your Power Supply Again

Thanks to a built-in self-heating function, this battery stays fully operational down to -4°F. Whether you're winter camping or surviving a cold-weather outage, it charges and discharges reliably while most other lithium batteries simply give up in the cold.

With 5.12kWh and 100Ah of LiFePO₄ capacity, you get nearly all of its rated energy unlike lead-acid, which caps you at 50%. That means longer run times for appliances, lights, and devices without worrying about damaging the battery.

A Smart BMS Keeps Your Battery Safe Around the Clock

The advanced Battery Management System watches over voltage, current, and temperature every second. It automatically steps in to prevent overcharging, over-discharging, and short circuits keeping both your battery and connected equipment safe without any effort on your part.

Rain, Dust, and Rough Roads Cannot Slow This Battery Down

The IP65 / NEMA 4X-rated enclosure blocks out dust completely and resists water jets from any direction. Combined with a vibration-resistant build, this battery handles boats, RVs, food trucks, and off-road rigs without missing a beat.
