12V 100Ah LiFePO4 Open Battery EVE A Grade 6000+ Cycles

Product Description

The Voltpro Energy 12V 100Ah LiFePO4 Battery is designed for users who need a dependable, long-life and high-performance energy storage solution for 12V systems.

At the heart of the battery are EVE A-Grade LiFePO4 cells arranged in a 4S configuration to provide a nominal voltage of 12.8V and a capacity of 100Ah, giving approximately 1280Wh (1.28kWh) of nominal energy.

The battery uses a JK Smart BMS B18S10P to continuously manage and protect the battery cells. With 100A continuous discharge capability, up to 200A peak discharge and 1A active balancing, the BMS helps maintain cell voltage balance while providing essential protection during charging and discharging.

For high-current connections, the battery is assembled with 16mm² pure copper DC cables and 16mm² pure copper lugs. The main positive and negative cables are supplied in red and black, with approximately 1-foot cable length for convenient connection.
