Hi,
I hope this is the right place for this. If not I'm sorry. I was wondering if anyone might be able to show me how to build this? My balance/charger only charges 2s & 3s batts I fly mini and micro electric helis and I have several 1s batts I want to charge with it. I'm new to the battery scene and dont want to screw anything up. I have good skills with the soldering iron and would rather build my own than buy. My problem is where the shrink wrap is I dont know what wires go where. Maybe someone could post up a drawing or schematic showing how to wire it. Can anyone help?
