I didn't want to use 18v so I jump on e-bay and looked for a 12v dewalt battery. The average price was 40$ + shipping (no thanks). I noticed that someone was selling a black and decker 12v battery "that fit dewalt drills." I did a little research and verified that some B&D and dewalt batterys were interchangeable. I jumped back on e-bay I picked up a unopened 12v B&D drill + battery + "dumb charger" (Shipped $33). I got the drill and picked up the dremal of death and here is the product.

The battery charges on the dewalt smart charger just fine. All I need to do now is mount it everything.
