2S BMS Cnnection instruction:
B+ Connect battery positive;
B-Connect battery negative;
MB Connect the point between battery1 & battery 2;
P+ Charge/discharge positive;
P- Charge/discharge negative;
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 board.
