That's a MAYBE.... Overvolting this motor to 72V isn't what really hurts it, The issue is people overamp this motor at the higher voltage and overpower it. They put too many amps into it and it gives them issues.
There are tons of people using 72V on the mars and Etek motor on evalbum without any issues.

Hell, Mars 0709 is a 72V motor on their datasheet for it. I've seen curves for other Mars motors and it's the same thing, they have 72V curves. It's not about the overvolting, it's overloading the motor and not putting in place correct current limits on the motor controller.
I've not seen any examples of a 48V pancake motor "melting down" at 72V with correct current limits in place..... maybe you would be kind enough to provide some examples? I'm being serious, if there are example I think the myself and the OP would like to know. Maybe there's some quality issues with new ones?
