Note:

1. Strictly according to the diagram wiring: 0V/4.2V/8.4V/12.6V, Otherwise it will cause damage to the chip.
2. After connection, it needs to first charge activation, then will have the output.
3. Do not mix the good battery and poor battery to use. The internal resistance of the 3 battery capacity is closer will be better. Please, buyers, know the professional knowledge of this module before buying.
