Over discharge protection detection voltage

(2.4±0.05)*n(V)

Battery voltage is less than the protection voltage, and the delay time to reach, then the state of the battery into over discharge protection.

Over discharge protection delay time

100ms max

Overcurrent discharge protection current

55-65A

Battery discharge current is greater than the protection current, and the delay time to reach, then the state of the battery into overcurrent protection
