The protection board uses lithium iron phosphate rechargeable battery protection IC;

1. High-accuracy voltage detection circuit;

2. The terminal is connected charger with high withstand voltage devices;

3. Built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit);

4. Through the MOS transistor can control the battery charging and discharging;

5. Low standby current consumption.

Welding Point:

B + Connected battery cathode;

B-Connected the battery negative;

B1 Connected battery connection point between 1 and cell 2;

B2 then the battery connection point between 2 and 3 batteries;

B3 battery is connected to the battery connection points 3 and 4;

P + Connected charge / discharge upright pole (charging terminal / discharge terminal shared);

P-Connected charge / discharge terminal negative (charging terminal / discharge terminal share).


1. Note that the input and output voltage, and load current conditions, the protection board power consumption does not exceed the allowable Power dissipation electrical parameters;

2. Pay particular attention to the load current can not work long hours between maximum continuous operating current and over-current protection current;

3. The situation is not likely to occur when you connect the battery discharging. In this case, connect the charger can be restored to normal operation;

4. The battery over-charge and over-discharge of the battery mixed together in series, the protective plate and the overcharge state of over-discharge state, the battery can not be charged and discharged;

5. The protection board built-in electrostatic protection circuit, but please do not hand protection when working in electrical panels to touch the plate, so as to avoid damage from static electricity protection board.
