OK, I have eight six volt batteries powering the coach including the residential refer., wired in series and parallel. I have deep cycle golf cart batteries rated at 226AH @ 20 H I see where the Shunbin has a 400AHrs. So, if I figured it right, I have 904AH, which divided by two , gives me 450AH of usable power. I see Lifepo4 by Shunbin has a 400AH 12 volt for $1499 w/charger.
I'm looking to replace them. Is this a close enough match?
