The point of isolating the pack from the motor *and* the GFI are both
*safety*. They are not exclusive on one another, I recomend both! The
safety value is more than just avoiding shocks, its a second disconnect in
case of a full on controller. It eliminates any capcative coupling ground
from the motor while charging too.

I did not mean to imply it as a fix for a motor with a ground fault. That
should be fixed too. If you start with one ground fault and ever get
another you could have some serious fireworks. You could also get bitten
hard just checking a battery cable.
