I was wondering if anyone of you guys have performed this yet or considered it. I want to upgrade the Jeeps battery power by adding a second/back-up battery resource. I was considering installing it in the engine bay compartment behind the cooler since there is so much room availability in the V6. I want to link these two batteries and turn over all additional power using devices to this second battery. The battery would serve as the primary resource for auxiliary lighting (all cargo-mounted lights, guard-mounted lights, CB, and Scanner radio, on-board air, rocker lights and winch when I get those - AND would serve as the back-up battery source to start the vehicle should the primary fail.

It requires more electronics than I'm capable of understanding. Lol, I understand microbiology but very little about electronics. Anyway, I know I wanted to install a primary switch in the cabin that I can use to grant access to the second battery for the additional devices.


Thoughts/Criticisms/Concerns!?
