Thread: Dual battery Install

You are probably looking in the wrong spot, you have posted in the Series Land Rover section, not the Discovery section.

Moved to the correct area.

Discobaz,
There's a good thread on dual battery install into rear cargo bin in post:

http://www.aulro.com/afvb/discovery-...ery-setup.html

Within this long thread there is a lot of discussion of issues and there are links to other install instals.

Not sure if I've pasted the link correctly as I am not sure how to do it.

I've just finished relocating my dual battery from under bonnet to rear left bin. I'll take and paste a photo for you shortly.

Not really, for me. I'd already had the cabling to the rear power users (lights, compressor, water pump, fridge, camera, outlets) from the original installation so the only difficulties were getting support under the bin bottom for the heavy battery without pulling everything apart, and getting the location of the drilling through the bin and vehicle floor right so you don't hit one of the various captive nuts or floor ridges. Of course, space is always a premium so I've lost 3/4 of the bin and don't know quite what to do with the stuff I had in there. I am in the process of making a shelf to go over the battery.

I also included a bypass switch in the rear bin, in parallel with the isolator, so that if the isolator dies, the second battery dies or if you wish to connect both batteries without the engine running you can get power to the rear power users. I also used eyebolts as through the floor so so I can easily connect the battery hold down bolts and also remove the battery without leaving unsealed holes in the floor.

The only other thing is that I have gone to using bus bars for power supply but am amazed you can't seem to get 12v bus bars with covers. So I've had to come up with a cover for the positive bars to avoid unfortune shorting contact.

Hi All
I went from SLS to coils, just a personal liking, I have seen many a debate eaither way here. It left where the compressorwas free under the passenger door. Does anyone know of a dual install with the battery there? It looks like an 80Ahr will fit there. Its just the bracket to hold it in that would stump a double left thumbed person like me.
cheers

Hi Mat. I have a client at work who has a D2a V8 with coils, and he installed a 48A/Hr Optima Yellow top, on it's side, on the SLS compressor tray. He has a solar panel permanantley on the roof rack connected to the Optima.

As promised, attached are the photos of the rear bin battery install. Looks a little like a dog's breakfast in the first photo but it isn't that bad. The second photo shows the shelf installed.
