I run with one fine, they never burnt out, even when i burnt out 2 motors on one side (I was using the 24 amp Version but it's basically the same as 1 on 12 amps) , it didn't burn out, and it has heat protection and alsorts, there really good and adjustable, the fact they can fall of the metal plate on large impacts is the only problem, but if you mount it correctly it holds it in place.
