Overview
E-Power Battery Management Systems (E-Power Smart BMS) are designed for use with E-Power batteries. It can be modified based on customer requirements when sold separately.
E-power Smart BMS is used to monitor the temperature, voltage, current and status of 4 series lithium battery. It can accurately calculate the capacity and life of the battery. This BMS supports series and parallel connection of the battery, up to 6pcs battery modules in series, with a maximum voltage of up to 72V.
We will configure BMS according to your requirements. It supports to display some parameters on LCD screen or monitoring all available parameters to PC and mobile APP.
