Then Castle should remove the predefined 4s cutoff value from the options in the Link software. As far as the motors go, I'd say about half of the people running the MM ESC are actually using it with a MM motor.

Andrew: From various reports, any of the newer MM ESC's won't work with 14 cells. You can try it, but might just get some type of error indicator.

The earlier ones did "fry up." They worked on 14 and even 16...

This is for marketing, the MMM is to the point of be available, and this is for this reason that castle have modify the MM. Like that, the guys who just run 4s and was fine with the MM, could not take the MM, no choice to buy a MMM.
Maybe i'am wrong, but this is what i think.
