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 need 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 3 battery capacity are closer will be better.
