Yes, saw it too, really good reporting. There was a very good [in the
"real engineering facts" department] article some time ago, prior to the Samsung debacle. It was aimed primarily at electric vehicle batteries, and touched a bit on large lithium-chemistry batteries for the home. Tesla's "Gigafactory" making PowerWalls and vehicle batteries is about 45 km from us. It might have been in Scientific American, sadly I don't remember. But I do remember: The energy density of lithium-chemistry batteries is extraordinarily high, and they have an almost infinitesimal internal resistance. Consequently, anything that shorts even part of the battery is going to result in extreme currents and resulting electrical and pyrotechnic displays. The "secret" to safe lithium-chemistry batteries appears to be really good engineering and manufacturing quality control. I've had one LiPoly RC battery I used with my KX1 go up in flames while I was calling CQ in the Spartan Sprint. Fortunately, I was outside on the deck, it was externally connected via a pigtail, and I was able to fling it over the deck railing onto the gravel driveway. It's provenance was difficult to determine, but I suspect somewhere way way to the west of NV. If a lithium-chemistry battery ignites, water is not likely to put the fire out. Cheap isn't always a good deal, and I'd never use one internal to the radio. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 2/7/2017 3:19 PM, Ken G Kopp wrote: > Yes, the PBS / NOVA program was indeed informative ... and free of > political BS 😁 > > 73 > > K0PP > > On Feb 6, 2017 8:26 PM, "[hidden email] [KX3]" < > [hidden email]> wrote: > >> >> For anyone who would like to know why Lithium batteries can be so >> dangerous I ran across this interesting video from PBS Nova.

Re: [KX3] Lithium Battery Video

I agree with all of that. The ability to store lots of energy in a very small form factor and deliver it quickly as needed (low internal resistance) has been and will continue to be an enabler for many of the electronic marvels we pursue (including portable electronics, electric cars, and off-grid homes). Unfortunately, that is also precisely the physical definition of a bomb, and the key to being able to use such capabilities safely is predicated on proper design (quasi-intelligent current limiters) and effective quality control (elimination of variables at all levels). It's most likely going to continue to be a rocky road, and personally I'm expecting some spectacular failures along the way. 73, Dave AB7E On 2/7/2017 6:08 PM, Fred Jensen wrote: > Yes, saw it too, really good reporting.

I had a poor quality Lithium-ion pack explode with the force of dynamite
while recharging. Shrapnel was embedded in the sheet rock 8 feet away. The shock wave was so intense, it ruptured my left eardrum. I never considered that they could be dangerous. Now I know by finding out the hard way. The PBS show was excellent. Doug -- K0DXV On 2/7/2017 6:08 PM, Fred Jensen wrote: > Yes, saw it too, really good reporting.
