For celldiers, if you want them to charge properly, they need to be in a line Wink

Looks pretty good overall. I know how the time thing gets in the way.

One thing you might want to adjust is either the length of time the solder is on the cells, or get a bigger iron. If solder balls, it's not a solid contact. Most of the solder on those cells are balls, and not a blob. There shouldn't be any curves going "under" the solder, it should be more flattened.
