Different brands can charge and discharge at different rates.
My 3 Lion Energy UT1300 can each discharge at 150A and charge at 100A but prefer 45A. I upgraded my charger to a lithium rated one and went to 75A. Even at 45A it's just over 2 hours from 0 to full.
The beauty is that the charging rate doesn't slow down as they fill, like all lead acid based. Their "internal resistance" is much lower so the last 10% is as fast as the rest.
Those are 105 AH batts, so 3 x 105 = 315AH/75 amps = 4.2 hours
315/45 = 7 hours
So "even at 45A it's just over 2 hours from 0 to full"---where on Earth did you get that from?????????? :(
EDIT-- 105/45 = 2.33 hours
I think he was talking about just 1.
