does anyone know where to put an extra battery on the JK Wrangler, for such things as a waeco fridge, cheers chris...

 

Try doing a search on it and see if you can find something. There's somebody here that did a REAL nice install of an extra battery, but I cannot remember who it was. It turned out like a factory install. Looked like some of my work, in fact....and that's sayin alot. LOL

 

search is your greatest friend

try this excellent setup i myself is working on it

I am also looking for a dual Battery kit or a way to move the OEM batt sideways woithout too much mods so to allow the installation of a Hydrogen Bottle!!! Unles the batts are relocated to the back of the car and making mods to the storage tub....
