Mac powered drill

I have a very nice Bosch power drill, but that spends most of it time in the Munich Maker Lab as of late, and I needed one for a project asap.

I had a crappy one with a broken battery, and I had an old Macbook battery with one broken cell. So I did the obvious thing, I ripped the working cells out of the MB battery (in which everything was glued together *grrrr*), assembled a 3S lipo pack compatible with my rc lipo charger and transplanted that into the old battery box.
