Super-Duper 12-cell, 3-format 1S Charger
FP100 charger (less than $3!) and soldered in some eflight charging leads. It was easier than I thought. I didn't need to unsolder the FP100 connector from the board; instead they were perfectly sized and positioned to be solder pads for the cables. I did open the case to do the soldering though, so I wouldn't have to be so precise in navigating the soldering iron in the plastic case.
I've hot glued the chargers to an old USB hub, and will power the hub from a wall wart power supply. I think I'll be able to fit six of the chargers onto this particular model. I wish I could find some 3 inch cables! If I were to go totally insane on this project, I would eliminate the connectors and directly solder the power leads.
I'll check the amp rating on the hub and power supply to see if it will charge 12 batteries simultaneously at full power; It would be cool if it did, but I imagine I won't be needing to do that very often.
