Product size:59*20*3.4mm
Product weight: 4.4g
Charging voltage: 12.6V
Maximum output current: 20A
Maximum output power / charging power: 252W

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.

Note: 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
