There are 7 Emoli cells in a Milwaukee pack. There should be 10 A123 cells in a Dewalt pack, each with a nominal voltage of 3.2-3.3v and a full charge voltage of 3.65v at room temperature. Unless you have special equipment, the A123 cells are not ideal to charge. Also, I've read that you're not supposed to solder directly to the A123 cells (at the center is the pressure release point), which is why A123 sells a Developer Kit containing 6 cells each with tabs welded onto them.

There are some tutorials and the like on disassembly/assembly on Emoli/Milwaukee cells/packs.
