Precautions:

 

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.

 

 

Attention:

 

Do not mix the good battery and poor battery to use.

The internal resistance of 3 battery capacity are closer will be better.
