AI Overview
Battery protection board testers (BMS testers) are specialized devices used to verify the functionality of lithium battery management systems (BMS), including overcharge/discharge voltage, overcurrent protection, and balance efficiency. These testers often connect to PCs, providing fast, accurate simulation for 1-32 series battery packs.

What does a battery protection board do?
During charging, the protection board monitors the battery voltage. If it exceeds 4.4V, the board disconnects the charging circuit to prevent overcharging. Similarly, during discharging, the board ensures the voltage doesn't drop below 2.3V. If it does, the circuit disconnects the load to avoid damage.Mar 7, 2025
