[QUOTE="2023 LTZ, post: 8834439, member: 686684"] Enthusiasts Is there reason to believe that different batteries can be safely separated by a battery isolator? Looking to add a deep cycle to the mix. Battery companies recommend when adding a second battery that they be the same. The isolator companies insist there’s no benefit in having a second battery if it’s not used while the ignition is off. Camping enthusiasts begin speaking of air conditioning, lighting, pumps, hours of use between charging. I’ve gathered that I can add a deep cycle to my trunk and have it isolated from the front and feeding my amps. I believe the alternator is capable of charging it and the start battery as well as the electrical demands of the vehicle while it’s driving. I have a stiffening cap but this seems less than what’s needed. I believe the alternator will never put out a steady voltage so I’m over that but wonder if this second battery will “cushion” the electrical dips that the system sometimes experiences. Is it right to think using this deep cycle will cushion the higher demands of my audio system? [/QUOTE]
