Glad you weren't hurt - whew! It might be a good idea to report your experience to the Consumer Product Safety Commission. If your battery had a defect there's a distinct possibility other batteries from the same lot or manufacturer are defective also. Getting the CPSC involved might prevent someone else from being injured - or worse. There are downsides to packing more and more energy into smaller spaces. EDIT: In a related item, I just noticed the following on UPS' website: --- Service Update International regulations applicable to air shipments of lithium metal batteries have changed. Compliance with the new regulations becomes mandatory January 1, 2015. The regulations, published by the International Air Transport Association (IATA), prohibit transport of lithium metal batteries (shipped without equipment) on passenger aircraft. As a result, UPS will limit transport of these shipments to within its International Dangerous Goods (IDG) network. --- 73, Al On Wed December 10 2014 6:39:25 pm Doug Person via Elecraft wrote: > Have to admit, outside of actually combat, that was the scariest thing > I've ever experienced.
