I agree with you 1000% on boondocking. I love it. I miss it.

Pianotuna thanks for taking the time for an explanation. I think I understand, sort of.
I'll admit that I'm hooked on boondocking and living off of solar
So in theory a person that has a 12v operating system could use all the same wiring then configure batteries in 24/ 48v get components to match.
Once again thank you.

Yes, I made all the adjustments to the Victron (Peukert, etc) based on the battery manufacturer's recommendations, but it's still not accurate. We're not talking a small discrepancy, more like the BMV shows 83% charge (with voltage at 13.2?) vs 98% on the BMS panel. And this after a full charge the day before - sitting in driveway hooked up to shore power.
I surely have a setting wrong somewhere, just haven't had time to drill down into it.

Not being argumentative just trying to understand better.
Lately it seems more suggestions are to go with higher voltage always by people who don't use the higher voltage but always claim the next time they'll do it. If it's so great why not do it now using the same wiring you have now (should be little to no V drop seeing it's bigger wire). The only thing that seem your changing is the battery configuration and a couple components.
What exactly will it do in an RV that I'm doing now and have been for years? I know run the AC unit but in order to do that for a long period of time won't you need a larger battery bank so it's not depleted even at 24v or 48v? 12v @ 400ah, 24v @ 200ah 48v @ 100ah all equals 4,800wh it's the same capacity isn't it? Or does this benefit more a lead base battery compared to lfp battery?

If you plan on a large inverter definitely jump to 48 volts. I'd pick Outback or Victron with a hybrid (load support) feature.
Mind me asking why? What's the benefit to the higher voltage?

I just did a battery revamp and added 4 lithium batteries, stayed with 12v setup due to pre-existing 12v inverter charger. Very happy with it, They donโt sweat high draw loads, but iโm finding that my Victron 702 is not an accurate indicator of charge. I think it calculates it based on amps out but doesnโt seem to jive with the readings I see on each of the batteries via their BMS panel. Some tweaking to do there. Agree that amps in and out will be the main indicator, but not sure yet how to accurately show that via the 702.
