What is this BS Castle is feeding this customer?

Personally, I think someone isn't telling the whole story. The truth is that if a MM ran the system before, changing to a MMM with the same motor and battery setup will change nothing. The motor will draw the same current as before and the battery will see the same load as before, neglecting any minute changes for the resistance of the FET's that have changed between ESC's.
