The recommended max voltage for the continous servos is 6v for long life.· If you use anything above 6v you can damage your servos or significantly shorten the life span of your servo.
Like Dave said using a voltage higher than 6V will shorten the life of the servo, but if that isn't an issue 7V should be fine, the consensus is that somewhere around 9V your servos will immeadiatly self destruct, between that·and·6V is possible but you'll need to replace them more frequently.
