Update!
Hey guys so I did a little digging on the electrical setup on my RV. And I am confused. As a reminder this is how I bought the RV back in 2016 in terms of the battery setup. There is 1 chassis battery up front for cranking, 2 more batteries up front for Coach and a Battery at the Fridge that is (I believe) also connected to the other 2 coach batteries up front. The first photo below shows the battery at the Fridge. I thought the cable I am holding went up to the other 2 batteries since it carries a load, but after tracing, it goes back to the onboard generator. So that explains how it charged when I am running the generator. When I unhook that same cable from that Fridge battery, it still has power though and the generator is NOT running. I never traced it until today as I just assumed it went up front to the other batteries since it was carrying a load while not plugged in and not running the Gen. The fact that the cable has a load without hooked to the battery and without Generator on its got to be getting power somewhere?? The Voltage on the battery noticeably increases when I plug into shore power, so to me that battery is getting power somewhere when plugged in??
The other pics shows the battery bank up front. All three battery grounds go to the main shutoff you can see on the very left. I see a total of 3 solenoids. I tried to get a pic of all three together so you all can see where cables/wires run but it was tough to get it all - Its a bit of a mess :) I haven't touched any of that stuff as I am afraid to mess something up. There is so much electrical going on it's a bit intimidating. I am not sure with this setup if these batteries are considered in Parallel? Which gets me back to my original questions on going with the Lithium battery setup. I have been in contact with Battleborn and their customer service has been top notch so far. I sent them a few pics and am waiting on their recommendations. If I cannot just drop in the batteries I will likely just stay with how I have it set, but from what I have explained to them on the setup, they seem sure that just dropping the Lithium batteries in will be just fine. Anyone have any input on all these solenoids? From what I could tell 1 solenoid is standard and goes to the starter. Another goes back to the Generator and I will have to check on the other. But they all seem to be connected to each other which explains why I also charge while driving down the road. Anyway, a lot to unpack here but appreciated any and all help!
Threw is a side view for the heck of it :) May post a few inside as well as thats been updated quite a lot. Thanks all for any input you can provide! Oh the joys of an older motorhome. I must say I do love it though.
