I would have to defend some of the abusers/misusers. The documentation that is being supplied with the MMM systems clearly states that, "High quality batteries are not needed, but will not perform as well", Or something like that. But in reality and later learned once failure occurs this is bad information. Bad batteries are killing the ESC's, at least that is what I was told by support. I know the MMM is a powerhouse. But until the manufacturer educates the end user properly before damage, they can expect alot of failures.
Just my .02 cents
