Heck Chris, how about 15-20 minutes?
I have an off-grid solar backup 48V pack of AGMs, so wired an Anderson 
SB175 to it and directly to the nicad pack on my I-5 (60 bb-600 nicads 
that previously poured 1800 Amps into my Karmann Eclectric dragster).  Do 
the olde Frankenstein connection time the dump pack, grab a beer and 15 
minutes later it’s time to mow.  I haven’t bothered to chart the amps, but 
there’s no hot spots and amps are definitely down after a 15 minute dump 
charge.

Charge On,
