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, over current, over heat, etc. It would cut off the battery input or output for protection once necessary. Overall, the BMS helps to ensure safe and accurate running.
