Hi, I have a 2017 silverado 1500. I would like to set up a dual battery system, but i'm getting bogged down with all the info and technology on these new electronic systems. Apparently you cannot use a traditional dual battery isolator on the new trucks with the smart alternators. So I found numerous versions, but they all have widely varying descriptions so i'm finding myself spinning around and unsure of what I actually need. there are smart isolators, but there are also dc to dc battery chargers for use in dual battery set ups. what do I need ? do i need both the smart isolator and a battery charger ? or just one or the other ? ugh... I just installed a yellow top optima as my primary, and will add a smaller yellow top for the auxillary. the brands I have found include: Redarc, Victron, smart gate, keyline, etc. THe prices are all over the place. I m certainly in no position to spend a thousand dollars to do this, so hoping i'm just confused with what I need and there is a simple resolution. End result i'm looking for....... dual batteries, isolating main from aux so that I can protect starting battery , while using aux to power accessories, then my alternator charges both while driving. sounds simple right ?
TIA
I also found a blue sea systems ACR unit that sounds like it fits the bill, but again, confused as if that is all i need, or ?????
