I was wondering what is underneath the 12V battery under the hood of a 2.0turbo JL. I know the 3.6 jl has the small auxiliary underneath the starting battery. Is that cavity just left empty on the 2.0? I know the 2.0 doesn't have the small auxiliary underneath since it has the 48 volt battery in the back under the body. I am looking for a place to mount/install a small LiFePo4 battery to run a fridge or other accessories while camping/overlanding and thought this area might be good if its empty.

I'm interested in this too, but for different reasons. It would make a nice (waterproof?) spot for a winch solenoid or air compressor.
Yes I thought about a dual ARB compressor here also. But think I might go with LiFePo battery here if it’s empty and has the room. Was just trying to find out if anyone has already taken the top battery and fuse panel out and knows what’s under there and what kind of space is available before I tackle it and investigate. Everything I ever see is in regards to the 3.6

It just the empty box, I pulled the flare while running the wires for the side steps through the firewall and the box is there and empty.

Hmmmm, I would think that the heat in there would kill the potency. There are much better places to hide it :rock:

This is an amazing idea. I would think that placing a LiFePo here would be perfect. Apparently you can also upgrade the size of the main battery. Just would need somewhere to mount the control unit.

Yeah these are all the ideas going thru my head. Just need to do some researching and planning before I put into action. Kinda new to this electrical auxiliary battery wiring and setup stuff.

Well I decided to go the compressor route instead of the LiFePo battery in this location. I removed the empty auxiliary battery box. I then cut a .25” aluminum plate to mount the twin ARB compressor to. The plate mounts to the 3 screws that held the auxiliary battery box in place, plus 2 more screws that come thru the bottom of the main battery box. I then ran “push to connect” air line to a pressure gauge and then thru a pressure regulator mounted on the topside by the main battery. The air line then connects to my factory rock sliders that I welded airtight to act as 2 small air tanks. They hold almost 3 gallons of onboard air combined. I then ran air line for a rear connection inside the fuel door and another mounted inside the front bumper on the passenger side.
