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.
