Hot Rodding a Power Drill Battery

Step 6 Now the tricky part...

After getting the battery assembled I removed the electical tape. The bars are very rigid and have no problem holding the pack together. Soldering the bars on and getting everything to line up is the hard part. Be patient.

The real tricky part is the cell that sits on top of the pack.(red wire attached) This top-most battery sticks up into the shank of the battery case. The little black plastic bit houses the stock connectors that mate with the actual drill and charger...so save that and be careful not to brake it.

The top battery needs to be attached to the battery direcly below it and sit slightly offset. B&D accomplishes this with another plastic part that I tossed. I used one of the stock battery bars that I pulled off the stock battery pack since they were thin and flexible. Both batteries were soldered to the sock bar while they were sitting next to each other. Then, to move the one onto the top, I just folded the battery bar in half...clear as mud...I guess I should have taken a picutre. Finally I wrapped the bottom of the top battery with electrical tape to prevent any shorting.
