Notice:

 

1) Please note that the input and output voltage, and load current conditions for power protection board does not exceed the electrical parameters of the allowable power consumption;

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

3) When connecting the battery ,it may not discharge. In this case, connect the charger can be restored to normal working condition;

4) Although the BMS built-in electrostatic protection circuit, but please do not hand touch  when BMS in the working condition, so as to avoid damage from static electricity protection b
