Okay this is interesting. You obviously burnt the motors out here but did you install a rudder some place OR were you still using the VECTOR THRUST ESC that comes with these NQD boats?!
IF So you found a cheap sollution for most NQD owners..
1. Replace the motors with some that can handle the 14v and your done.
(untill the esc burns out)
or
2. Replace with 2x480's as described earlier and toss in an 11v LiPoly 2000+ cell
(untill the esc burns out)

So, I was bored the other day and found a couple of extra battery connectors in my tool box.
With carful thought decided to run 12 cells (two six cell packs 7.2V 30A 3300mah each).
OMG! The boat is fast with 14.4 volts. Motors got a little hot, but to be expected. I know I will probably burn the motors out pretty fast running 14.4, but the motors were 10 bucks a piece. The motors are rated to handle 7.2 to 9.6 volts. So, if I am running two motors in series, with two batteries connected in series, what resistance will the dc motors provide, both motors arent recieving 14.4 volts, right?
