Instructions for lithium battery protection board 1: Overdischarge protection recovery: After the protection board is under over discharge protection, the battery voltage continuously increases when it is stationary or in a charging state

When the protection board detects that each voltage is higher than the recovery voltage of the over discharge protection, the load is disconnected or charged again, and the protection board outputs a signal

Turn on the discharge MOS tube and it can be discharged at this time.

Lithium battery protection board instruction 2: overcurrent protection: When the battery is in a static or discharge state, the current suddenly increases. When the protection board detects that the current reaches the overcurrent protection value,

At this point, the protection board starts timing, and when the current duration in the circuit reaches the overcurrent protection delay time, the protection board outputs a signal to turn off and release

The MOS transistor and load locking circuit are working and cannot discharge at this time.

Lithium battery protection board instruction 3: Overcurrent protection recovery: After discharge overcurrent protection occurs on the protection board, the discharge MOS tube is turned off, and the current in the circuit becomes 0

Disconnect the load or charge, output a signal from the protection board, turn on the discharge MOS tube, and discharge can be carried out at this time.
