We insulate the poles with Kapton tape.
Solder the balanced protection controller.
We glue it to the batteries with double-sided tape.
We solder the wires to the charging connector and insulate them with heat shrink.
We install it in the case.
Solder the wires from the connector to the charging controller.
Next, we solder the wires from the controller to the converter via a switch.
