Welcome to the forum, Karl.

It's pretty simple. Put an isolator up the front, run a pair of decent-sized cables to the back where you mount the battery and make sure both ends of the positive (red) cable are fused. Try to run the cables in a protected area.

If the battery is under the tray, it could be exposed to water/dirt/sand/mud etc, so after you've hooked it up, give it a spray with that blue stuff that auto electricians spray onto battery terminals under your bonnet. It will help stop corrosion and debris from getting into the joins.

+1 to tony and his idea. If its not wanted under the tray you can either buy a battery box from anywhere really or make a custom box like most of us here. I would use some 6b&s wire between the batteries and an isolator to keep things charging and also so you don't kill the starters. Even if its in the tub I would still put that blue stuff on the terminals.

Thanks Tony should i get a under tray tool box to put the batt in

Personally (if I had a tray and I was putting the battery underneath) I'd make a lockable enclosure for it, just so I could be sure it is at least difficult for someone to knock it off or damage it. If the tool box does it for you then go for it.

Just make sure it's not air-tight. Even "sealed" batteries - VRLA, Gel and AGM - will emit hydrogen gas if charged hard enough.
