Welding point Description:

• B+ : Connect to the battery positive
• B- : Connect to the battery negative
• BM: Connect to the battery 1 and battery 2 joining point
• P+ : Connect to the charge / discharge side of the positive terminal
• P- : Connect to the charge / discharge side of the negative terminal

Precautions:

• Strictly according to the diagram wiring: 0V(B-)3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit.
• After the line is connected, Need to charge first, then have output.
• When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use.
• Do not mix the good battery and the battery.
• The capacity of the battery internal resistance is closer will be better.
• Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying
