Hi everyone,
I have a 2011 3.0L Patrol & I have dual batteries. The 2nd battery Century N70T deep cycle is mounted in the engine bay on the passenger side with a arb tray behind the airfilter box. Currently using a Projecta isolator. Ive had this setup for 12months now & the 2nd battery is stuffed already. I really dont want to replace batteries every year.

So Im thinking of replacing my isolator with a Redarc DC to DC charger which will charge my batteries to it full capacity.

The location of the 2nd Battery is not the greatest as its next to the turbo & exhaust manifold so there is alot of heat over that side of the engine bay which I think killed my deep cycle. So Im thinking of mounting the 2nd battery in a box in the back of the car & use a AGM battery. Alternative mount a Marine style battery in its current position in the enginebay but wrap the battery in some insulation.

Any ideas on this? Im liking the battery in the back idea but I suppose the only downside is it adds to the already crowded rear of the car, also the extra 30kgs for the battery in the back

Any help would be good.
