Enerdrive ePOWER B-Tec Lithium Batteries
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.
Smart Phone Monitoring System
The Enerdrive ePOWER B-TEC battery incorporates wireless Battery Monitoring Technology. By downloading the Android™ or Apple® app to your smartphone or tablet device, you can monitor battery capacity, voltage, current, state of charge, battery health and more.
