GOOD grief!
I ran across this on an aviation website. It details a small LED flashlight that exploded due to [apparent] lithium battery "runaway".
Lithium batteries are apparently like Nicads- the more current they deliver, the warmer they get. And the warmer they get the more current they want to deliver. It is a vicious circle, and nicad batteries routinely catch on fire. Lithium batteries apparently blow up! Look at the pictures- this is insane!
This flashlight? It uses those little 3 volt lithium cells. It exploded, took out an aluminum sliding patio door, and then flew 90 feet!
I have one of these and removed the batteries as soon as I saw this!
