Probably more like 3 to 3-1/2 hours. The first 100AH would flood into the
batteries in about 1/2 hour, and then the rate would start dropping, but it
would still be putting it in way faster than a 75 or 100-amp charger for quite
awhile. In the comparisons we were doing, 75 to 100 is not a huge increase. 100
to 200 is huge.

I don't believe there is any way you can push juice into a battery at maximum
amps while constraining voltage. If there is, that would be fast, but it defies
the nature of a lead-acid battery.

I've certainly thought of it, and might consider it if I was a year-round
boondocker like some people I know. For us it is about 40-60 nights per year,
and not worth the aggravation.
