same here use a thermocouple attached to my 902. also place the batteries in a ammo can with the batt connection on the outside, so if i need to eject the ammo can out of my 2nd story window to get it out the house i can. i also have 3 break away points in my system 1 inbetween the deepcycle/ pwr supply and the charger. second is the jacks into the charger to the battery so 3break away points. so ifthe charger starts to flame out can dispose of it. i dont sit and watch each n every second of the charging but i am in 10' of it with a co2 extinguisher. i ed like argon but only at work as they only work well inside.

I guess you have to feel sorry for the guy, however, it would seem the proper precautions were not taken in this instance. too bad.
when I would charge my batteries before the temp gauge wire was added, (BTW, it should be standard issue, if the jack is there) I would always "baby sit" the batteries, but now if they start to heat up, the charger kicks out and an alarm goes off, which all chargers should do. I would imagine that the owner of that charbroiler would have given anything if he HAD been in there at the time.

For Li-Po fires you need a class D extinguisher. It is a lance that ejects loads of black powder. They make one hell of a mess all on their own
A standard dry powder extinguisher works just dandy on LiPo batteries. We aren't dealing with a mangesium wheel or engine block (vw's used to have them, maybe still do, I've been out of the fire service for a while) but you dont need a MetalX extinguisher to put out a model battery.

The issue I have is that in order to see the "little bit of smoke" you have to baby sit the batteries and don't take your eyes off them for an hour (or more). NO DISTRACTIONS! How is that even feasible?
I didn't say a "little bit of smoke". I said it smoked for a little bit. I'm not saying that they all smoke for a while before catching of fire though.

The last one I saw go up smoked A LOT for probably a minute before bursting into flames. (CY's Henseleit Rigid w/large Outrage lipo 8-12S?, happened in flight. He had enough time to auto it, run over there, and pull it out of the heli before it started burning)

I had to read the link - because he said "black powder". Now I realize he meant black colored metal powder. Applying _black powder_ would certainly make things interesting.

Ask your doctor if your heart is healthy enough for Radio Control Helicoptering.

What I don't understand is here, we are sitting here having numerous people with issues of exploding batteries, whether it be during charging, storage, or discharge, and yet the laptop industry has been using lithium batteries for years (probably more laptop lithiums batteries out there than RC batteries), and yet with the exception of one incidence with a recall Dell made on a screw up they had with their batteries where one caught fire, I haven't heard of any lithium laptop bonfires. The only difference I can see is faster discharging and recharging. If that's what it is, while we can't avoid fast discharging, we can avoid fast recharging.

Anyone know if the laptop computers have a built in balancer as well?

I treat them with respect, and the car fire encouraged me to finish my storage setup.
Three metal steel ammo cases with vent holes drilled near the top.
These then go in a steel filing drawer, nothing else in the drawers to burn.
All my charging is done in a Lipo Sack, never unattended.

Sorry for your friends loss but publishing it may have saved some others from being careless and losing a car or home. Thanks for sharing.

My ammo cases.

]EDIT: I have seen a car burn like that from a lite cigarette. The driver flipped the cig out his window and the back window was open so it went onto the back seat. By the time he realized he was on fire he pulled over on the side of the interstate, but by the time someone (trucker) showed up with a fire extinguisher it looked like the 2nd picture.
So store your cigs in a fireproof container.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Sorry about your friends van. what a shame and especially because it was a handicap van.

I prefer lipos for heli's and nitro for planes. I fear the lipos but that just makes me more careful with them. I have seen both nitro and lipo fires. the only thing is nitro after a crash. I charge my lipos on my wheel well of my jeep. I'm going to change that to the floor in front of my jeep with some longer cables. Sorry for your loss but your post has done its purpose as a reminder.

Lloyd,
we tried that with some older puffed packs that we wouldn't fly anymore and all we got was a small puff of smoke. we charged them and then stabbed them with a garden rake.

Here is my only lipo fire so far. During a crash one of the cells got nicked. For about 15 secs nothing happened, then smoke started squirting out of the cut, next a flame hot like a road flare, one cell after another until all five cells had there say that they were not going to fly anymore.

.
A little burned grass and a lot of cussing.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Sorry for the loss but:
(1) He left the lipo unattended
(2) He left it unattanded in a vehicle (full of combustibles)
(3) Ii does not matter what it is, if you mistreat ANYTHING on a heli whether it be a lipo, a nicad, a gallon of nitro, a gallon a gasoline , or anything of the sort, things like this can happen.
(4) Mutt does not like lipos, he is entitled to his opinion no matter how misplaced it may be
(5) We fly, play with, build, and repair some of the most dangerous toys in my opinion.......who doesn't want a little danger ......................Ron

I think I need more detail about how it happen.
What does it mean ,don't charge your lipo
batteries unattended .
it is impossible to look at your battery 2 hours long while it been charged.
When it happen only a second . Only time run away save your life

Chances of an accident is hegher when you have more of anything.. Nitro heli have less chances of lipo mishaps, simply because we only need one or 2 lipo packs for the entire weekend. hence, a lot easier to manage when there are less of anything. having said, Nitro heli is still not exempted from such mishap..

EP like what one of the post here mention, the owner rush to pull out a bucket of another 10 lipo pack.. Dude.. With that many power plants to take care of, and the enthusiasm for a great day at the field and who would want to miss a good chat with the buddy?? With this. less attention is place on minor but potentially hazardous details.. ie, cold solder joints, worn out joint which may cause brownout, sparks, bad cells, bad chargers etc.. and last but not least, Patience, as everyone wants things done in double quick time, and everything done all at once so as not to miss out the fun..

It's like taking 2 kids to the park vs 10 kids, where chances of losing one is higher if there's any guardian lapses..

Sorry for what have happen. We all just have to learn to be careful and be responsible for what we have..

Just like what Uncle Ben said to Peter Parker. "With great Power comes Great Responsibility"

everything in this hobby has its dangers. you just have to know what safety measures you have to take. this reminded me of this guy that flies in a field where I used to fly that charges his batteries in his BMW 650 while the engine is running for a/c. he believes this will prevent his batteries from blowing up. I would love to go to that field and show him these pictures. doubt he'd listen.
