Unless you are asking about stall torque.

All stepper motors have stall holding ability.

But you must consider the fact that the motor windings will get hot
after a while and can be damaged if abused.

Yes, it should do.
Its a motor controller not a battery. It doesn't "hold" any voltage. If you read through the whole instructable you will find your answer in step 8.
