I´d say though that all (and I mean all) blown packs I´ve heard of, has been caused by mistakes by the user or a manufacturing error in the batteries (very rarely happens). Either not setting up the charger right, not monitoring the charge properly (check that the charger detects the correct # of cells) or not having the plane setup right with lots of airflow over the high-stressed batteries. I think the problem here is when people who have never flown electric before, go get 10s2 or 10s3p lipo battery packs, without knowing in detail the care and effort it takes to keep them working in a safe manner. So basically I think that while the technology can get a lot better (more forgiving for user errors), I wouldn´t blame the technology itself for the problems encountered by some pilots.

Just my 2 cents.
