Be careful:Lithium iron phosphate battery can not be used for lithium battery protection board, hernia lamp, electric hand drill battery pack, electric fish machine battery pack, electric bicycle battery pack, children's car battery, more than 550 power motor, 1W fish eye LED lamp. Customers who use the above combination to buy are requested to pay attention!.

Main functions:Overcharge protection, over discharge protection, short circuit protection, over current protection

Wiring instructions:B + to battery positiveB-connected to negative pole of batteryP + battery pack output input positiveP-battery pack output input negative

Matters needing attention:1、 Please pay attention to the use 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 electrical parameters.2、 The load current cannot work between the upper limit continuous working current and the over-current protection current for a long time.3、 When the battery is connected, it may be unable to discharge. In this case, the charger can be connected to return to the normal working state.4、 Although the protection board has built-in anti-static protection circuit, please do not touch the board with your hands when the electric protection board is working, so as to avoid electrostatic damage to the protection board.
