What do you mean with running just one lead? if that is about the controller; then no, the controller uses different powerboards; if you use only 1 lead instead of two, the controller can't deliver the current, since you are not using its full capacity.

What I meant is there are 2 positive battery lines, 2 neg and 2 for each of the 3 motor lines. So both wires have to be connected for the controller to work correctly?

Any pointers on how to solder two fat wires to the little deans connector?

Thank you! Damon

Well, you could use 5.5mm plugs instead of using the Deans connectors. Just make sure use heat shrink wrap the female plugs real good. Also consider using and one female 5.5 and one male 5.5 on the battery (and vice versa on the ESC) to avoid "polarity" accidents.

Deans plugs are great but as you mentioned small and a major PIA to solder two large wires to them.

BTW...I would advise against using only one each of the double wires. That is a hi amp ESC and it has double wires for a reason.

Thank you all for great advice. I spent a few hours resoldering today and used the sandwich technique. It was really challanging with the deans. It works GREAT! It was really jumpy from the UBEC, so I cut it off and put a battery pack on it, it is awsome. A little cogging, but it has never gone so fast! And the temps are no where as high as they were before. The ESC never broke 100, and the motor about 110 max with plenty of speed. Once again, thank you!
