This way, a BMS helps prevent your battery from:
Overcharge
Overvoltage
Overcurrent
Overtemperature
Cell Imbalance
Shorter life cycle
Additionally, a BMS optimizes your battery capacity and overall performance in every charge/discharge process. This way, you can get the most out of your LiFePO4 battery pack regarding performance and lifespan.
