“ That means you can restore 125AH in an hour which means you have a 125 amp charger. Also that the batts get to 100 with no tapering. The Onan gen can run the 125 amp charger.”
So with SiO2, sounds like there’s no chemical soup resistance?...Not sure what you mean here but I must say that that is pretty dang impressive, outpacing even LiFePo4 !!...
Either way, for uber efficient off-grid solar harvesting (within peak harvest window), internal resistance is a factor worth considering...

No! That was in reply to the guy with 250AH worth of LFPs.
SiO2 are limited to about 30% charging rate, same as regular AGMs. Some gen time advantage with SiO2 over regular AGMs is between 80-90 % where they stay constant amps before tapering around 90%, and that you can start the high rate constant amps from 20% instead of 50% (LFP can do that too) so no wasted gen time while amps taper if doing a "20-90"
I covered that in my SiO2 testing in that long thread a couple months ago.

"I almost believe I could deplete my batteries and charge them twice by the time you had yours done once just using my 2200w generator."
As in the example above, you could do 125AH in half the time it takes the same size bank of FLAs to do that many AH doing a "50-90". All you need is a big enough amp charger and a gen big enough to run it.
Gets harder to compare 500AH banks with RV size chargers and gens! Have to be very specific what the two things are being compared.
