thats not true ... if you run 2 batts with an isolator it doesnt just work with the jeep off. the vehicle batt powers the vehicle and the second batt powers your acc. winch, lights, etc. when the jeep is running it charges both and still will only draw power from sepreate batts.

 

Just wanted to update this thread. We're still offering the best deal and the most comprehensive Dual Battery Kits. https://www.jk-forum.com/forums/show...00#post1134700

Also, watch that thread in the coming days for a complete Smart Isolator and Wiring Kit.

Thanks!
