A "Lithium Energy Storage Battery Protection Board"(BMS) is a critical component designed to safeguard lithium-based energy storage systems (ESS) from operational risks and ensure long-term reliability.

It actively monitors and manages voltage, current, temperature, and cell balancing to prevent "overcharging", "over-discharging", "short circuits", "overheating", and "cell imbalance".

By automatically isolating the battery during abnormal conditions, it enhances safety, extends cycle life, and maintains stable performance in high-capacity applications like solar energy storage, grid backups, and industrial power systems.
