Please pay attention to the conditions of input and output voltage and load current, so that the power consumption in the protection board does not exceed the allowable power consumption of the electrical parameters.
The load current cannot be operated for a long time between the upper limit continuous working current and the overcurrent protection current.
When the battery is connected, there is a possibility that it will not discharge. In this case, the charger can be restored to normal operation.
Although the protection board has built-in anti-static protection circuit, please do not touch the board by hand when the protection board is working, so as to avoid static damage to the protection board.
