Actually mine are flooded (T105s). Trojan says to charge at 10-13% of C which would be approx 22-30A. But, if I understand correctly, slower is fine when on commercial power and not worried about running a generator. Is that correct?
The only time I'd charge fast is on the generator. I know you said 2 GC2's at 50% will happily gobble up 60A for a while, which I would aim for on a generator, at least from 50 to 80.
