You need a class D fire extinguisher. They are not cheap. The typical ABC household extinguisher will be ineffective.

I believe a lipo battery on fire is a chemical reaction fire. It will burn without oxygen. I mean fire needs oxygen to burn, so im not exactly sure.
I'd just use a metal ammo box like GTDC said. Good containment

Cell Phones and laptops are NOT using LIPO technology..
they are using LI-ION which is much more stable and lower output.
and not as prone to exploding or fire as LIPOs

Well we took a grille ran power up thru middle and have power supply and charger on grate so now batteries can burn and will be contained . Everything is new so really shouldn't have any more issues .I stole it ,flew it and gave it back ;)

Guys, are we seeing more of this now that we are charging at higher charge rates? How about just plain complacency with charging?

I too almost lost my house from charging a lipo. I was using a Schulze charger (not a cheapy) and felt like it would handle any situation that occurred. (There, I admit stupidity!!!!) Boy was I wrong. I also never properly stored my lipos. Now, all my charging is done outside and I store in an ammo box outside. Some of us are just hard headed until it happens to us.

As far as cellphones and such, don't most of them use lithium Ion batteries instead of lithium poly? Plus they aren't charged at really high rates like we do.

Yup Tag I posted that above.. Cells and Laptops are not using li-po mostly LI-ION
not sure other than some Military radios and RC are actually using LI-PO

If you open some Cellphone batteries you will find a regular softpouch style Lipo. At least the batteries I broke apart (Palm Pre chinese and EVO Extended size Chinese) were made that way. They also had a temperature and overcharge monitoring chip.
Maybe that's why exploding cell batteries are mostly cheap chinese clones.

um bro it may look like a LIPO.. but its a LI-ION..
all it takes is a quick google search.. NO ONE uses LI_POs in phones.. they are too dangerous.

LI_ION is stable LI_PO is not.

If that's the case, why does the label on the battery in my Droid say "Lithium Ion Polymer"?

I guess they are just too dumb to label it correctly, since Google answers are never wrong

Short class LOL love copy and paste LOL

Li-Ion and LiPo batteries have essentially the same chemical make-up and are cared for in the same way; the differences are in how the cells are packaged and the type of electrolyte that is used.

Li-Ion

Li-Ion batteries use an organic liquid solvent as the electrolyte. This electrolyte is responsible for the ion exchange between the electrodes (anode and cathode) just like any type of battery. This organic solvent based electrolyte is highly flammable and the reason why Li-Ion batteries are more volatile and can catch fire or explode if mistreated. Li-Ion batteries are usually encased in a hard metal can (again like a more conventional battery) adding weight and not allowing many different options as far as shape and size.

LiPo

A true LiPo battery doesn’t use a liquid electrolyte but instead uses a dry electrolyte polymer that resembles a thin plastic film. This film is sandwiched (actually laminated) between the anode and cathode of the battery allowing for ion exchange – thus the name lithium polymer. This method allows for a very thin and wide range of shapes and sizes of cells.

LI_ION is stable LI_PO is not.
So why is LI_ION stable if it contains a flammable electrolyte?

Sorry about your accident.

Never put trust in a bag, just because they sell it, and call it fire proof, lipo safe bag, what ever.

When I charge, I'm never more than a room away from the battery, if I leave it unattended it's only for a few minutes, and I'm never far away. Always within smelling/seeing distance. I've charged Name brand batt's, cheap ones, used ones. Never even seen one puff.

Lot of times, I believe the batterys have been abused to much, and the last charge does them in. Or the batt gets hooked up wrong, or charger set wrong.

Off topic but it amazes me how many people fly crashed lipos either as a main pack on an electric or just as bad a receiver pack on a nitro.

I routinely give crashed packs away and find them on guys helis, lol, I guess they don't mind their $2000 helis going up in flames because they are too cheap to buy a $30 battery.

I also get a kick out of the "smell" test, if the battery is crashed and somehow passes the "smell" test it's good to go ... lol, not on my helis, if the pack is physically altered in a crash, I'm done with it.

I've been intending to buy a few ammo cans for a while now. This thread finally spurred me to do it. I've been taking my chances for eight years and that's long enough. Thanks.

Our RC lithium polymer batteries are not the only ones that go up in flames. There have been many instances of lithium batteries in phones, laptops etc. experiencing catastrophic failure both on and off of chargers. Last summer I personally warned multiple contractors here in Louisville Ky. about the dangers of leaving their cell phones, iPods, laptops and any other device containing a lithium polymer or ion battery in the car. Two days after this warning the Project Manager with the General Contractor showed me what was left of his Apple iPod. He left it in the car on the dash. It went up in flames before lunch time and burned a hole in the dash of his SUV. He was very lucky the plastic in the dash was fire retardant and there was no paper in the immediate vicinity to further fuel the fire. The outcome could have been much worse.

Um read what you just posted there.. THAT IS LI-ION

2 different technologies..

holy crap man.. see that little word there that says ION thats where LI-"ION" gets it's name..
