There is a circuit board in the Battery compartment and it may switch back and forth but the affects would be the same. I would guess they didn't get that complicated with the circuitry. I know the internal battery compartment is setup with three banks, the cam can run on 4,8 or12 Batteries. you can put batteries in the first, second, or third bank with the other banks empty and the cam will run. You can run with no internal batteries and just the external battery and the cam will run. I'm guessing the cam sees the external battery as just another Bank. Also you can't charge the internal batteries in the cam, my guess is there is a blocking diode in the circuitry to Guard against feed back and allow the current to flow only one way.
