Motors have a maximum current they can use, and a battery that can
supply higher current doesn't provide any added run time.  (that's the
case of nicad tools running on an li-ion battery).  But if you give it
less, it will produce less power.  The first cordless oscilllating
multi tool I had was an m12 that came with a small battery, w/ one set
of sells in series.  It was garbage, couldn't cut at all, battery
lasted no time at all.  Put an XC battery on it, with two sets of
cells in parallel, and it worked much better, and the battery lasted
longer than you'd have predicted based on capacity.  (it was still
crap.  The m12 fuel currently available is worlds better, though.)
