BT2.0 interface 1-6S charger

I've recently been using a 65-cell battery pack, but discovered I didn't purchase a charger, and the charger price was exorbitant.

I planned to create a simulated 4S battery cable, but this cannot be arbitrarily increased or decreased, only charged in fixed quantities.

Therefore, I created this 1-6S switchable charger.

The front of the casing houses the balance and XT connector outputs; the rear 3mm circular holes lead to a wire connecting to a BT2.0 female connector.

This female connector is designed to plug into unused charging ports.

For instance, with only four batteries, plug the BT2.0 female connector into port five.

Absolutely ensure that after connecting the wires, you test each interface individually with only the balance connector plugged in to verify proper recognition.

Required Materials

6S balance cable                      1

XT60/XT30 female connector          1

BT2.0 male connector                  6

BT2.0 female connector                1

M2*10 machine screws                4

Optional:

16AWG wire

18AWG wire

(The wires between the positive and negative poles can utilize excess wire from the balance connector, but 18AWG wire is recommended; thinner wires have insufficient current carrying capacity)
