So I have abandoned my plan to have an under bonnet dual battery system, I had the intake out, made up brackets and mounted tray and battery to test it out. It lasted fine over some heavy 4x4ing, however I always change my mind on things, so....
I made myself a battery box. I had the box laying around, drilled some holes, fitted a volt gauge, merit plug and a switch to turn on the volt gauge ( I will probably change to a flat style switch, this was all I had laying around). I will probably add other plugs later on. Posi and earth run to an anderson plug. Everything is fused under the lid of the box.
I ran 4 gauge cable from the front, under the kick panel and the scuff guards or whatever you want to call them and up to an anderson plug, earth is under rear seat. Charge cable is fused under the bonnet and on battery side of the anderson plug.
Just waiting for my solenoid to rock up so I can finish the under bonnet wiring
At least this way I can pull it out for portability if needed, and I'm not lugging an extra battery around all the time. It just doens't fit behind the fridge even sideways, so will have to have the fridge out in the middle like this.
