I heard about this phone thing and thought it sounded a little fishy. Cellphone bats are tiny, I wondered how the heck it could have killed a guy!

Person 2 becomes agitated and / or offended and says that Person 1 isn't allowing them to express themselves

Sad, but true.

Co-worker confesses to killing quarry worker with drilling vehicle

4:55 a.m. November 30, 2007

SEOUL, South Korea A death originally thought to have been caused by an exploding cell phone is now being blamed on a co-worker, who confessed to making up the story after accidentally striking the victim with a drilling vehicle, South Korean police said Friday.
The quarry worker, only identified by his family name Seo, was found dead Wednesday with a melted phone battery in his shirt pocket. Police and a local doctor who examined his body said a malfunctioning battery may have killed the man.

After reading of the actual chain of events, I kinda wish it would've been a Li* accident.

Sad story... Thanks for following-up

These are pictures of my Giant Stinger that was setup for Electric Flight. We had 10 LiPo cells of 7400mah range. This plane ran a 24x12 prop and sucked about 95 amps constant. We had a cell burst while in flight and the plane actually was in flames on landing. These are what is left of the plane. Mind you the charger said the cells were charged perfect after charging. We let the batteries set for a few minutes after charge and took off. 1-1/2 minutes into the flight we saw a extremely dense smoke trail , at that point we knew we were in trouble. Good news is the skydiver on the bottom did jump for his life and was fine!!

Wow edge pilot, wow. . .

I am glad it was safely landed and not just a flying heap of fire!

We did not even think of the receiver being on fire until we landed and opened the hatch up. The receiver was a melted ball of plastic and copper wire. Woke me up to the proper care of large cell LiPo packs.

I witnessed a similar "in-flight" fire to that one last year at our field.

After careful dissection the fire was determined to have been started by a faulty and very expensive brand new ESC, not the battery pack. The battery pack joined in the "in-flight" conflgration making for a spectacular smokey display.

The smell was hideous, though.

So I'm going to have to join the "Well, I'm dumb" club when it comes to Lipo batteries. I'm just getting into lipo's and building my own packs. So today my order of 31 cells came in and I had soldered a couple connectors onto a couple different cells to do some testing with and see how long I could make a Walmart special AirHogs Plane run with one of my new 600mAh cells when my 6 year old daughter walks in. She goes to pick up a couple of the cells to look at and I gave her a lecture on lipo safety and if they short or get punctured they could blow up and that she should never even pick them up if i'm not around. So I was putting the cells away in their containers and I noticed one of the cells move on the table. Sure enough, one of the insulators on the - side came off and it was shorting the two poles across a screw driver and beginning to heat up and balloon. Luckily for me and my house I was prepared for what could happen and grabbed the cell, ran out on the deck and threw it in a pile of snow to watch the explosion. To my surprise, it cooled down shrunk back to normal and held it's charge, I let it sit for about 30 minutes outside, checked voltage and put it on the charger. It charges fully to 4.14v just .03 short of the other cells. I won't ever use this cell in a pack, but it may be ok for testing things with and who knows, maybe one day i'll make my own lipo destruction video to post here.

The reasons for lipo fireing is multifarious.
The quality,the storage,the operation.....
So we should take more care of the products,and flying.
In a word,safe or not depend on ourselves.

lipos in cooler or compact fridge in garage??

I have read several posts on storing lipos, and if I go that route, would like to determine the best place for storgage.

Some store in a garage, but some say, it is too hot in the summer or too cold in the winter, and not the ideal place. Some say they don't want to store in the house due to the danger of the toxic fumes corroding the house should one set off, even if the fire is contained.

If they were kept in the garage, what about in a vented fireproof safe (sentry 1100), with the lipos in a lipo bag, and put the safe in a good ole fashion plastic food cooler lined w/ sand, or even a compact fridge from walmart for $70, since some also store them in the fridge?

I would like to store them in the garage and in Colo, the winters and summers are not too extreme, but it can get cold and hot at times. The cooler and/or compact fridge would also provide additional protection from fire? I could even run a garden hose from the cooler drain hole to the outside for additional venting to the outside?

Heck, I could store my fish bait in the compact fridge too if I didn't go the cooler route. Any thoughts? I now have to explain to the wife why I have a new additional fire extinguisher, smoke alarms, cinder blocks, firesafe and flower pots.

hehehe, right....
If you want to play it realy safe, just put the packs in individual bags (to prevent shorts from the leads touching), and place them in a clay planter or pot, filled with dry sand. Then put a clay lid on top of that. Even if a battery burts into flame (and why the H. should it do that?), all you'll get is a smoking pot.

I have kept my lipos in my "battery fiel-box" (just a toolbox large enough to carry the charger, balacer, all the cables I need, plus the batteries) in the house, for some years now.

If you got a bad lipo that you planned to recycle anyway - go outside to a far away dirt road and try to make it burn... keep a safe distance and all that, to be sure. You will be quite disapointed, or astonished, how hard it actually is, to make them blow.

I have seen lipos that got shorted from badly done plugs. What usually happens is that the solder tabs melt through, or they just desolder.
The only 2 ways to make them actually bloat, burst and burn is to overcharge them, or drain a lot of amps (enough to make the cell in the middle get real hot, without any chance to get rid of the heat).
