Size:53 mm×17 mm×4mm/ 2.09″ ×0.67″×0.16″(L×W×H)
Suitable for:
10.8V (Rated voltage of polymer battery)
11.1V (18650 or 3.7V lithium battery rated voltage)
12.6V (Lithium battery full charge voltage)
Attention:
Strictly according to the diagram wiring: 0V(B-)/3.7V(B1)/7.4V(B2)/11.1V(B+),Otherwise it will cause damage to the chip.
Do not mix the good battery and poor battery to use.
The internal resistance of 3 battery capacity are closer will be better.
