Battery Life
I posted this question on another RV forum and Ill be darned if I can find that forum. (arrgh). So much for keeping good notes. Anyway, I have a 2016 Dutchman Denali 38ft 5th Wheel. I'm thin...

But wouldn't a pair of 12V batteries do better cooking a costco size box of hot pockets?
Flooded batteries are "rated" at a 25 amp draw @ 25 C (77 f)
So 4 pairs would give a continuous output of 100 amps, with 450 amp-hours of reserve (8 jars)
That may run a microwave for a time, and many folks have done so, when the wire is big enough and the bank is close enough to the inverter.
8 pairs would be 200 amps, with 900 amp-hours of reserve. (16 jars)
That would run the microwave for a long long time.
1 SiO2 can do 342 amps and a pair can do 684 amps, with 200 amp-hours of reserve.
So IF you go by rated capacity, the pair of SiO2, in THEORY ought to be a bit better than 4 pair of golf cart jars, as a single SiO2 can run a microwave at 20% state of charge. I would imagine that with twin SiO2 the microwave would run at 10% state of charge.
It boils down to which is cheaper per amp-hour and how much weight one can carry.
