I’m planning my upgrades for my new 4xe Rubicon. One of the mods I was considering was a dual battery setup to get rid of the aux ESS battery. Do we know if the 4xe will have a aux ESS battery or will they just use 4xe battery pack for power? Can we tie into the battery pack for our power needs or would use the standard battery like a normal Jeep? Sorry if these are newb questions, but it is my first Jeep and first hybrid vehicle.
