Ok. I bought that charger and the universal pigtail. Total came to $125 for everything. I am going to end up making adapters for all my packs. I am going to make them all like the Team Orion lipo pack, just balance port type. I have a maxamps 4400mah saddle pack that I took apart already, an rc common sense 4000mah battery, and going to be getting some A123s soon.
