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"

except with the LFP batteries you can do that from empty to full and a lot higher current than SiO2 even. the curent charging restriction is why I am not concidering them, well and the price. I think that even with normal GC batteries if you have a big or multiple charge sources you can charge faster than SiO2, with a 25amp limitied charger that is all you can dump into it then of course it will charge faster than my LA, but if I am dumping 75 amp into my GC then I think Ill win the race. for me this is why the Li are more attractive. I can dump 150 amps into them from empty to full if you have that kind of charging. so realisticly say you have 75 am converter and a 30 amp solar set up you could fill a 280ah li back from empty in under around 2.5 hours. or for the people with gennys using for the 2 hour allowed time they could totaly fill there bank in that alotted time and not use the evening genny time. to me i think the capacity size and speed of refill are the teo morst important factors , well life also and Li blowes anything else out of the water for all three. even cost for Li is now the cheepest if you build it your self per/usable capacity.
