Generally the only way to know the amp capacity of the ESC needed is through testing, recommendations, or previous experience. The voltage and prop are going to be main things determining how many amps the motor will pull. Of course the ESC needs to be a bit over the maximum drawn by the motor. The mAh capacity of the battery has almost no effect. Adding a larger capacity battery of the same voltage does not require a higher amp rating on the ESC. With a bigger pack you may see slightly higher amp draw due to less voltage sag. That's one reason you want a little safety margin.
