Did you at any time have 2 BEC's operating at the same time? and to the correct polarity?

Another question.  Did you disconnect the ESC's BEC before reconnecting the ESC to the receiver ~with~ the receiver batteries still connected?

If the batteries connected to the ESC and the batteries connected to the receiver are both the same voltages there should be no problems.  If they are not the same voltages, there certainly can be problems.  Paralleling two simular batteries doewsn't increase voltage.  Paralleling two dis-simular voltage batteries creates 'smoke' somewhere.
