How much volts did you use ??
It might have burnt the motor,striped the gears or fried you FETs(somehow)..

Donzii said that you shouldn't use above 4.8v I think, that little motor can't take it dude.

I mean, people wreck the motor on 4.8v, I wouldn't doubt that it wouldn't work on Li-ions..

You really don't need li-ions for the servo motor. That motor is fried no doubt.

Are you sure it isn't your Xmod? Check all the connections from the motor to the ESC, even inside the servo case to make sure a wire just didn't pop off. If everything is in tact your probably fried your servo, somehow.

Whatever voltage your can run safely through your ESC can be used to run the servo. However, because we put these servo motors under such strain, it causes them to weaken and "fry" faster. Most of the time this isn't reversable unless you know what the problem is; the motors are just too hard to disassemble, fix and then reassemble.

My guess: you've ran the motor at the higher voltage for too long, causing it to get too warm and not be able to disipate the heat fast enough. This caused your brushes to lose contact with the communicator and stop the motor.

Is it a HS-55? Mine blew out with stock voltage so the same might have happened with yours.
