My turn to build... DIY Dual Battery Tray

Start by removing the monster battery tray. This thing is one huge molded plastic piece that connects the battery tray, fuse box stand, and air box mounting locations all in one mold...take it out:



Next you will need to cut off the section that your fuse box and air box mounts to. You will keep this section and discard the other:



Remove this reservoir from the front of the Jeep to allow easy installation of your new tray:



Make a template using foam poster board for your main mounting plate on the firewall:



Transfer that pattern to your 10 gauge and cut out the template. Next measure the battery width of the batteries you want to install. I found that you can't go much more than 7.25" on each battery compartment side for a total of 14.5" floor plate. It just fits, but barely, weld the sections together after you find your center line and cut a center support:









Remove and fabricate the plate the fuse box and air box base will sit and attach to:





Add a mounting post for the Evap solenoid, drill holes for water drainage, and prime for paint:





Paint your choice of paint:




Install in the Jeep:











Second Bat in, everything hooked up and working properly. Good to go.

That's really slick. Great work.

Are you concerned at all about the battery closest to the engine getting too hot and possibly boiling?
I buddy of mine constantly has this problem in his 4Runner.

No..there should not be a problem. This DIY is exactly what you would get from the other manufactures like Rugged Ridge, Benchtop, etc. If there was an issue with the battery overheating I think that would have worked out already. However, it wouldn't be to much of problem to line the battery with some type of insulation.
