Install Rating (3rd Party Work 10 = Best, 1 = Worse)
I installed a stirling 50Amp battery to battery charger under the drivers seat behind the house battery. This done due to the fact that our old Zig charger burned out whilst servicing the needs of my daughters to watch TV ALL the time. It is an excellent system, gives us a great charge quickly and looks after our house battery really well.
I put in a 15mm sq stranded cable via grommets under the van, passing it though a plastic tube to prevent rubbing.
The cab battery end protected by a 100Amp fuse and and isolation switch.
