I do not understand how pulling the red power wire out plug of the ESC cable to the receiver will void the warranty?
You do not have to open the ESC itself to do that?
Just lift up the little lip on the connector of the receiver wire, and pull the little red cable out.

Do not power the receiver with the ESC and a seperate BEC at one time!
That will blow up your receiver, most likely.
