you can but it will run the hot side...I prefer to as high of voltage as you can afford...when you run higher voltage paired with a lower kv motor your system will be more efficent.
to be honest if i could find the 1515 and mmm in stock somewhere i would probably go that route ...but it seems impossible to find...LOL
it would be a good idea to deciede what voltage you want to run before you buy and than buy the motor that is a good match for it..I have learned the hard way (trial and error).....
