Welcome to camper paradise Gary 🙂 !!
Questions to you Sir:
When you say 84%, does this mean 84% of 225a/hrs (e.g. 189a/hrs consumed), or something different?
Does your CPAC run off 12vdc or from a 120v inverter?
Would Lithium be an option for you?
Just trying to think outside the box here – lol …BTW, for clarity only 6v’s are wired in series, while 12v’s are wired in parallel…
