And I could use some help.
Here is the case: New-to-me Chevy AWD has a smallish single chassis battery and it has side posts.
I hate em.
For the time being I'll be rolling with one battery and this weekend I'm adding a small house fuse panel off the main power supply wire for the cab fuse box, which fortunately is right under the driver's seat. It's 4 or 6 gauge from the engine bay which was a pleasant surprise.
So, I will eventually add an isolator, probably inverter, solar and full house setup off of a house battery but for now I need to improve upon this smallish side post battery for an upcoming trip.
I could add the screw in charging post lugs and get some military style terminals for the time being (I actually already ordered this stuff, just can't decide if I'm going to use it):
Or I could just go get a bigger chassis battery, say a group 31 with studs instead of posts. I like these because you can very easily add things like winches or extra cables to isolators/batteries, etc. I'm considering this guy:
The current chassis battery seems healthy, 2019 sticker on it. It's an 800 CCA, 110 reserve capacity, group 78.
For the time being I am going to add only 1 thing to this chassis battery, winch wiring, but I can't even do that with this side post only battery.
Another consideration. There is PLENTY of room for the bigger battery. Some people have even done 2 78's side by side but I don't have time at the moment to build a mount for both. I should probably also note that the group 31 is almost 20# heavier than the current group 78. No matter what the specs are that's a good bit of lead.
