So, MA packs are killing MMMs. Hmmm, sounds a bit odd. Like someone said, they don't seem to popping caps or FETs, just something on the controller board.

I agree with others: What works on the MM should work on the MMM, electrically speaking. If the appropriate cells for the application are selected, things should be fine. Yeah, excessive current draw should trip the LVC and/or overheat/puff the cells quicker.

Could it be something related to the AC ripple on the power line not being filtered enough for the BEC's liking?

Could it be something slightly wrong with the FET switching where both legs of the H-bridge are switched on at the same time for like a micro second? That would short out the pack for a VERY brief time, yet not damage the FETs because of the short time. True, this is unlikely, but this whole thing sounds odd.

Even if this is true; with any new release, there's bound to be issues to iron out. Even in extended testing, it's very difficult to test every possible scenario and setup out there. Before people start pointing fingers, we should hear direct for MA or CC to see what exactly is going on with the failures.
