Some of you know that I've been using laptop batteries for a number of things. From Flashlights, RC, Power wheels, Transmitter, Receiver, and rumors of breast pumps.
Well I have a cheapo chinese drill with even cheapo nicads. Also have a 12 yr old Makita drill with bad batteries. So instead of buying some overpriced nicad pack to replace them, I opted to use the 18650 laptop batteries. I have a choice of 3s or 4s on the Makita, which was originally 9.6V. Son of a monkey is one powerfull setup now. The chinese drill got a 3s2p pack, for really really long run time when I polish metal pieces.
