4. Circuit Protection
The batteries are supplied with a LiFePO4 Battery Management System (BMS) that can monitor and optimized
each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge,
short circuit. Overall, the BMS helps to ensure safe and accurate running.
