Amp draw is determined by prop size.. in your computation, increase your prop size 'til you get to the amp draw you need (but stay within the motor's limit).

ESC's don't limit amps.. they let through what they are capable of letting through... exceed that and they fry.

The low current to the motor indicates that the pack cannot deliver what that calculator suggests is what the motor/prop would demand, without dropping voltage.

NiMh cells (1.2v-1.4v HOC) typically can maintain only about 1v under load... in the same way Lipo cells (4.2v HOC) will be at 3.5v-3.8v under load.
