Features:

Module name: 3S 12.6V Li-ion Lithium Battery 18650 Charger Protection PCB Board

Suitable range: For nominal voltage 3.6V 3.7V lithium battery(Including 18650,26650, lithium polymer batteries)

Product Size: 64mmx20mmx3.4mm

Material:Metal

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.

Attention:

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

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