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
