The 18v grip  (and nicad pack) can fry the motor drive pins. Sometimes it
will do it if the motor / nicad (already screwed together as a pair) are
then mounted to the camera with the nicad / grip switch turned ON. (I
discovered this caution is featured in atleast the nicad instruction book,
it may be in the 18V grip instructions too, I'm not sure)  This can cause a
power surge and may cause the experienced motor damage.  In the 18v grip it
can also melt the battery contacts inside the grip AND the contacts on the
battery holder.
This melting can also occur with the 18v grip if the switch is OFF,
depending on what day of the week it is, or where the moon was positioned
the night before ;-)
