What's so hard about putting together some cells? I've put a couple together, for testing, at work. It wasn't very hard at all. I know your supposed to use a spot weld to attach the battery tabs, but we didn't want to invest in one, so I just used a decent weller soldering iron. Turned out perfect, with no damage to the cells. They were LiFePo4 cells, but I'm sure any of the chemistries is just as easy.
