Lithium battery protection board is a kind of electronic protection equipment for lithium ion battery pack, its main role is to protect lithium battery pack, prevent its overdischarge, overcharge, short circuit, overcurrent and so on.

Overcharge protection: The lithium battery protection board detects the lithium battery voltage. Once the battery voltage exceeds the charging limit voltage, the protection board will immediately cut off the charging circuit to prevent the battery from overcharging.

Overdischarge protection: The lithium battery protection board detects the lithium battery voltage, and once the battery voltage is lower than the discharge limit voltage, the protection board will immediately cut off the discharge circuit to prevent the battery from overdischarge.

Short circuit protection: The lithium battery protection board can detect the current in the battery pack, and once the current exceeds the limit current, the protection board will immediately cut off the battery pack circuit to prevent short circuit.

Overcurrent protection: The lithium battery protection board can detect the current in the battery pack, and once the current exceeds the limit current, the protection board will immediately cut off the battery pack circuit to prevent overcurrent.

Temperature protection: The lithium battery protection board can detect the temperature of the battery pack. Once the temperature exceeds the limit temperature, the protection board will immediately cut off the battery pack circuit to prevent excessive temperature damage to the battery.
