APM ESC Calibration

I recently read the article on how to calibrate ESCs (http://ardupilot.org/copter/docs/esc-calibration.html) but had a question regarding how the battery should be connected.

If I';m using a power module, and using the manual calibration (where I connect the signal cables of the ESC to my receiver';s throttle channel), do I also connect the receiver to the battery?
Or will the powered up APM (via battery and power module) power the receiver AND the ESC regardless of whether the ESC is connected to the battery or not?

Thanks for the video. It was very helpful.

One question though, if I calibrate the ESCs using one APM 2.6 and I have to transfer connections over to another APM 2.6, do I have to re-calibrate the ESCs or will they remain calibrated?

Short answer, yes. 

Explanation:
When calibrating you are doing so to the Transmitter/Receiver pair not to the flight controller. Basically, it is to let the ESC know the PWM values for Minimum and Maximum throttle.

The APM method is a convenient means of doing all of your ESCs in one shot.  The APM goes into pass-through where it connects the throttle channel of your Receiver to all ESCs transparently, as if hardwired.  In pass-through mode the APM does not perform any of its flight controller duties.
