mamba 4600 capable of mutiple runs on 4s?

[Sammus]

One of the castle reps on here said that the MM esc cell rating is based purely on the max cell rating for the motors that come with it in their packages. So if they say you can only run the 4600 at 3s, I wouldn't want to push it beyond that - 4s puts it at nearly 70,000rpm which is beyond the recommended max rpm of even the high quality hand wound neu motors.
