Does anyone know of a way to neatly provide slack (So that electrical devices can be moved to convenient locations to service). For instance I would like to have the battery on my runabout tucked way into the transom, but I want to be able to pull it out to service and at least initially with the cables connected. And since the bilge pump attaches and travels with the battery, I would like slack there too without a mess of wiring. Is this possible?
