Just make sure you dont short anything! :P I've made a few 2s and 3s packs from the ebay guy. the + and - tabs are marked, so you just solder together in whatever config you want. When I did it they were the older style U series without copper tabs, and only 20C discharge. A bit harder to solder on one of the tabs (anode I think?) but since they are copper now it would make it a sinch. I guess you also need some decent wire and some good high current connectors.
