The PowMr battery is a rechargeable lithium LiFePO4 battery with a built-in BMS system that offers stable performance and long life. With a capacity of 300 Ah and energy of 3840 Wh, it provides a large energy reserve for demanding applications and long-term operation without frequent recharging. The nominal voltage of 12.8 V and M8 screw terminals allow for easy and secure connection to larger systems. Thanks to the LiFePO4 technology, the battery is suitable for caravans, motorhomes, boats, and solar systems, and is an ideal direct replacement for lead-acid batteries. The built-in BMS monitors over-voltage, under-voltage, short circuits, and temperature, extending the lifespan of the cells. High efficiency of over 99.5% and low self-discharge of below 3% per month ensure minimal energy loss even during prolonged storage.
Main features:
- Capacity and energy — high capacity of 300 Ah and energy of 3840 Wh covers even long operation
