A neat solution to the controller battery disconnecting/no power problem. If you fit longer batteries, the positive terminal spring plunger can be pushed in beyond the height of the castellated insulator ring. If the battery is rotated either during insertion or removal the positive terminal spring plunger lugs can sit on top of the insulator ring castellations and stop it providing a constant positive pressure to the pos battery terminal.
