Very tragic indeed, just glad no one was injured and it was a car instead of a house.

Sounds like he was using an external balancer. Any details on what charger was used?

That really sucks thanks for sharing. If you can't warn someone without mass hysteria so be it. I charge on my hood and in the back of my jeep with no thought that this may happen even though I know better.

Oh by the way I am charging receiver packs only because I am a nitro head. Can someone explain again why I am safe from a lipo fire?

Oh and I suppose next you are going to tell me to remove my receiver pack from my heli before charging it too huh?

Wow! hard to see the truth about the dangers of lipos.

Lets face it, until there is a better and safer lipo out in the market, there's going to be incidences being safe or not.

A buddy of mine was charging a lipo and caught fire in his van while driving. "Shame on him". Luckily he had a extinguisher on hand, he pulled over and saved the van from complete fire damage.

well seeing that the car batt exploded i am going to lean on the charger load was cooking the wiring under the dash which shorted and started the fire. when i worked in the auto trade i use to see all kinds of thing from doubling the fuse size to power 10 dc units in the car to them using aluminum foil

That would explain it then... he has been charging it in an "unconventional" way... (more than 20A draw?!?)(several batteries at the same time???)

Inside the car there should be a fuse preventing the battery and the cables to be overloaded... I guess that he bypassed that one...

there we go, I bet that is most likely the thing that caused the fire right there... If the fire started inside the vehicle, and the battery went up also, then most likely he was using a cigarette lighter plug-in to charge with, and it was too much on the wiring system, all the way to the battery. It wouldnt matter what charger you were using in that case.

well I dont know the story here, but a good rule of thumb with Lipos and charging , a Charger that has auto cell count , and a battery that is close to charged or Charged is a NO NO . it will go up in cell count and catch on fire. I have a few auto chargers and I have never had a problem. sorry to see this .

please explain, what chargers are auto cell count? the one I use (Triton and Triton 2) only wants to know the voltage, and mAh's, is it an auto cell count?

No, your ok with the Tritons, by setting the voltage, you are essentially telling it what the cell count is. 2 cell is 7.4, 3 cell is 11.1 etc...

I dunno man I think the auto cell count chargers like the FMA 4S and 10S are actually safer.
They wont let you screw up.
They automatically check cells and capacity before it even attempts to charge and pulls that data through only the balance taps rather than main leads.

Ive never even heard of a FMA accident.

BTW LipoSacs are your friends.. use them.

To clarify...

There are chargers that ASSume the battery cell count based on voltage. My high end Orbit charger does this but it requires a confirmation form the user with the option to turn the cell count down.

The FMA charger actually knows the true cell count because it uses information from the balance tap to count the cells and can identify broken cell...this all assumes the balance tap isnt damaged. I have a CellPro charger and its an pretty much as dumb proof as it gets but I still wouldnt consider it bullet proof.

Bottom line...no matter the excuse if you were not watching a pack while it was charging stuff can go wrong quickly. I never leave my charger unattended and if I have to leave for any reason I unplug the pack until I return.

The only thing a person should rely on is their own eyes.

r/e the original post:

Were the batteries being charged in either a "Lipo Sack", or an army-surplus ammo box? I would like to know from experience how effective those are at containing the fire, as I use both (not at the same time).

Also what kind of charger was being used, if that could be a factor? In other words, some 'root cause' analysis would be very useful.

the older chargers that dont have balancer connectors is the ones Im talking about , the astro 109 for one, also with the astro 109, dont disconnect from car battery and leave the lipo hooked up, ask Ray N . burnt up his little heli trailer at IRCHA 2 years ago. fire department got there pretty quickly and started throwing helis out the back door trying to find the sorce

Attended charge
What I don't see is how attending to the charge alleviates the issue. So when the battery explodes and you are beside it, how does it help? Imagine if the poor guy was IN the car!

From my point of view I want to stay as far away as possible. Not so sure there is enough time between seeing the battery puff and the explosion to attempt to do anything that does not involve getting closer to the battery...

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

The lipos I've seen go have always smoked for a little bit before bursting into flames. If you were there, you would have a little time to remove the lipos or move other stuff around it.

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?

My thoughts exactly. Unless you have an extinguisher in your hands aimed and ready to go whever a lipo is charging, what's the point?

It wouldnt take me no time at all to grab everything, charger, battery and anything else that gets in the way, out the door. If you charge batteries like I do, then you would be feeling them from time to time to make sure they arent beginning to get warm. I went and bought the temp wire for my charger, because I got tired of feeling them soooo much. it kicks it out if it gets over a certain temp.

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.
