Yeah the cut off voltage is not adjustable, factory set at 3.1 according to MGM. If you are seeing max amps of 2400, then I would say you need larger batteries to maintain voltage. It may also be possible that you are seeing the current limiting feature in the MGM (which is disabled in race mode). Even running a Big Maximum on 6s, I only saw max of 900 amps and with the current 2.5D it only runs 400 - 500 amps. Even thought these values are not accurate (according to MGM) they do give some indication of the maximum amps of your set up. I would try a larger capacity battery if at all possible, to see if you are in fact dropping the voltage too low. Perhaps try 2 of your current battery in parallel.
