is 4.35 the max voltage that can be used?

Yes and No. It may work for a short time, but more than rated maximum voltage will eventually overheat and destroy the motor. The higher the voltage the less time it will take to burn it up. That said, it could survive for short periods at 4.5v peak, but if you are doing much more than that, you'll kill it.
