C rating mostly decided on being able to hold a voltage, which makes higher amp capable packs better. You'd be amazed at how high voltage spikes can get during braking, easily twice the pack nominal voltage with bad packs. Since the the MMM and MM both have 30 volt fets this was not an issue with the MM as 3s was the rated limit.

And this is why on 4s the failure rate for the MMM is far lower than on 6s, greater difference between the pack voltage and fet rating... right?
