Step 3 Making the battery pack

I forgot to buy a battery holder, so insead of having to drive back to Radioshack to buy one, I just soldered three batteries together and duct taped them together. If you feel like it though, go ahead and buy a holder, and skip this step.

This is simple, just solder the "+" end of the battery to the "-" end of the other. It should be labeled on the battery which end is which, but if not, the flat end is the negative side, and the side with the little bump is the positive end.

Please note: soldering to a battery is an excellent way to heat up and potentially cause an explosion. It is best to use electrical tape or some other adhesive rather than solder directly to a battery terminal. Be Safe rather than Sorry and covered in an acidic mess!
