The MMM lvc is not a hard cutoff, the better the lipos, the softer the cutoff.
Castle was asked about the MMM cutting off early probs and this was their reply -
"After a cut off, if you go to off throttle and leave it there, and the ESC flashes green and yellow the ESC has hit Low Voltage Cut Off (LVC). It this happens prematurely the battery pack cannot maintain voltage under the load of the motor. You will need better batteries."
