What is max voltage for USA-1 motors?

What is maximum voltage I can feed to the USA-1 mega 360 motors?
Can I use 9.6V battery, if my ESC can handle the higher voltage? At least it should increase the power a little bit.

they are like any other motor. they should be able to take 14.4v, but will wear out the motor alot faster.
