Enerdrive Lithium Batteries eLITE and ePOWER B-Tec

Smart Lithium Battery with Built-in BMS

Available in 12-volt 125Ah and 200Ah capacities, the ePOWER B-TEC lithium battery is designed and intended for use in deep cycle applications where a single battery meets the amp hour capacity and maximum current ratings of the application. The battery has a builtin BMS which means that no external components other than a battery switch and appropriate fuse protection are required.
