edit: after 20 comments, i’m adding a post description here, since most of the commenters so far appear not to be reading the article:
This is about how surprisingly cheap it is (eg $15,000) to buy a complete production line to be able to manufacture batteries with a layer of nearly-undetectable explosives inside of them, which can be triggered by off-the-shelf devices with only their firmware modified.
Lithium burns intensely but it doesn’t explode. An electric car can burn for a long time, but they don’t explode. One of the comments says so
It shouldn’t be undetectable. Throw a device from s series into a fire as a spot check and if it burns it’s ok, if it explodes give the entire series to your enemy’s kids to play with.
Did you read the article? It sounds like you didn’t.
Are you able to say anything but that?
Heads up, I don’t think C4 explodes when burned. I think it requires electronic detonation or a blasting cap.
It’s right next to or in a high intensity lithium fire, not just a normal little flame. That should alter the equation somewhat.
