Only a comment to illustrate that these batteries can be scary. Not any suggestion that this was part of the 804 problem
Yes but the pack in the R/C Heli was also probably at least 0,5kg if not more. And it burns only very briefly intensely, usually about 2-3secs per cell if they are fully charged. (I have burnt a few/witnessed a few burning. The last 5 cell pack (0,5kg) last Saturday after it was damaged we drove a nail through it -for educational purposes). The subsequent smoldering is not very violent.
They have to be handled with care but I repeat -a 0,1kg LiIon or LiPo will not bring an airliner down as long as it is in an accessible place. It gets dangerous if it can ignite other stuff and is not accessible.
