Dual battery setup?

Been looking around for ideas on where to put a second battery for a dual battery setup. I know there is some space in the rear passenger side of the engine bay but that would preclude installing a snorkel if I am not mistaken and that is still currently a plan for me. Are there any other locations in which people have installed a second battery? I was actually considering rigging up a tray to place UNDER the Jeep somewhere as there is lots of room both front and rear for that kind of thing...maybe even have two extra batteries...has anybody tried this?

A couple guys have mounted them in battery boxes under the vehicle, and others have made a removable battery box that they connect inside the vehicle.

I considered doing a second battery a while ago but never bothered, but the removable box inside the vehicle would probably be the route I took

Others have placed them mainly in the rear driver side, behind the rear wheel in the bumper area. I have a spare tire carrier so I have planned to put mine where the spare used to be.

This is exactly what I was thinking too. Seems like a good place for it and almost seems like I might be able to get two of them up in there. Do you know of any write ups that anybody has done? That's what I have been looking for but the search function on this site is less than...useable.

I think .Tuco was one of them. I'll see if I can find a link.

I found the site and writeup you are talking about. Done in a Jeep Commander. This is actually my backup plan but doing this prevents me from being able to install a snorkel. Still debating on if I want or even need a snorkel so this may still be the way to go for me but looking for alternatives.

Here is a thread. @Tango. was the one I liked best. I can't find his specific thread which sucks because it had pics and better detail. Images are probably null at this point anyway.

What I did for dual battery was I hooked up a piranha DEE140SF relay that would connect the batteries after the Jeep had started. Then I hooked up (2) 150 amp breakers , one at each end of the battery cable going from the relay in the engine bay to the battery that I put in the rear driver side quart panel behind the rear tire. I used one of those steel optima battery cages from Jegs to hold the battery to the frame rail

This worked even when totally submerged.

Then I ran (with a 3rd 150 amp breaker to a marine fuse box in the rear cargo area and ran ALL my aux gear off the aux battery. ARB Fridge, Lights, Inverter radios etc.

My diesel is now sold.. and I really wish they still put that MB engine in the Jeeps. Best Jeep engine ever.
I used a deep cell optima for the aux battery, but you can get a cheep battery at walmart (automotive battery with warentee) and kill it cycling it and they are easy to replace in the jegs cage.
