Sand down the tip of your iron (if it has buildup on it), re-tin the tip, Sand down the ends of the batteries. Once all that was done, I checked the "layout" of the cells, and glued them together. I then let the iron get up to temp, placed the tip on the end of the battery, and applied Solder to the battery. (DON'T put the battery bar on right away. It will take too much heat to do it all right away) I did all the ends on one side of the pack. Then DOUBLE CHECK the polarity, and where the bars will go. Set the bar (or wire) on top of the solder ball, and set the iron on top of the bar. As the solder heats, it will automatically join the bar to the battery.
