[QUOTE="keep_hope_alive, post: 7692996, member: 576029"] the small terminals on the isolator are for controlling it. refer to the installation diagram/manual for the isolator, but you don't run ground through the isolator. you do ground on smaller terminal, and give 12V to the other small terminal when you want the batteries to parallel (i.e. when ignition is on). the isolator does not prevent the batteries from draining each other while the car is on. it only disconnects them when the car is off. with your planned system, you do not need two batteries. you do need one good starting battery. if you want to play with the car turned off for long periods, then the second battery will certainly help. a cap is a bulky terminal block and one that can give you issues down the road. best to just sell it (or connect it to 120V and let the magic smoke out).
