Detailed electrical parameters are shown in the picture

Suitable for:

1.Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit)

2.Suitable for electric drill with starting current below 80A and power below 170W .

Attention:

To successful starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 battery can not start the drill!! Recommended power battery models: VTC4, VTC4A, VTC5A, VTC6).

0V and 12.6V cable, use copper wire of more than 3 square millimeters (cannot use nickel plate!!!).

Strictly according to the diagram wiring: 0V/4.2V/8.4V/12.6V,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.

Package inlcuded:

1x 3S 40A lithium Battery Protection Board
