The motor may handle it but you have electronics and gearing to
consider, it seems everyday products get cheaper, so do the internals.

I doubt that for those voltage (6 to 18 volt) the electronics should not be
a problem. The motors and electronics may well be the same for all units
from a given manufacturer. And the electronics doesn't amount to much of
anything anyway. Not even as involved as variable speed AC motor drives.
