Silly question.

Just wondering, I have a warrior 9920 ESC and it only has one set of battery wires. To make things simple, could I just connect a deans plug onto the wires, and then make a dual deans plug adapter from this?

I would do what others have done with the wire between each pack, but would this not mean I would need a charger capable of charging an 18 cell pack?

Sorry if these have been answered before, but I couldn't see these answered anywhere.
