There's another way to think about this. There are probably billions of Lithium-based batteries in circulation world-wide. Yet, the reports of fires are few and far between. RC use is not a measure of safety because of the extreme nature of the usage. For example, I have a high-performance glider that draws in excess of 120A for rocket-like climb to altitude. Yet, those battery packs are a few years old and have never given me any problems. I don't know what the 787's issues might be. My money is on a quality problem at the battery manufacturer, not Boeing.
