Outer Limits 4x4 Board

gday lads,
am going to install a dual battery system into my rb30 patrol.

i already have a deep cycle gel battery here, so if i can use that would be good.

am wanting to run the second deep cycle battery in the rear of vehicle, as no room in engine bay unless i remove air compressor. I am wanting to rum just the stereo and dvd system and rear lighter plug in the back for fluros off the second battery.

wondering if the deep cycle will perform alright. just throw me some ideas guys. will also need to by a kit, what would you advise for this.

cheers

ive installed the redarc ones off Egay on 4 4wds so far and not one has failed! i swear by them, easy to fit and work real good!

cheers
