Curious what the general opinions on dual battery setups in 2024 is.
Got a 96 K2500 Burb 7.4l. Previously had the second battery tray added, but the battery on that side doesn't fit, the other batt is dead (2.5v) and the wiring is.... special (pretty sure OEM doesn't route the starter wire through the passenger control arms. Right now the plan for this thing is the camping/family hauler, some towing, general purpose kickaround. Not planning on making it into a living space - I have my trailer with its own battery for that. I am planning on installing a winch I already have and some radio gear.
So as I see it there are a few ways to do this
2 Starter batts, completely tied. Easiest to do, gives double CCA, can have something left on prevent starting
1 starter and 1 deep cycle batt, completely tied. Again, easy. Can have some charge limits and stuff between the two
2 Starter batts with isolator - Added cost of isolator, would find one with a failover function
1 starter and 1 deep cycle with isolator
I'm about to buy batteries, so I need to get that part figured out. Right now I'm leaning toward just 2 starter batteries. If I want to add an isolator down the road its only 1 added cable.
