Someone tagged me on Facebook because they knew I had a P3P.  They'd seen this video about a battery exploding causing a fire.

That is a scary occurrence.. Never heard of DJI batteries going off.

I wonder if it was a third party unit?

Aside from the property damage, thankfully, no one was injured...

An inspire battery caught fire in carry on luggage a few years back.  That's all I recall.  Sell enough of them, it's bound to happen.

Note the guy on the bottom left knew what was important - regardless of the circumstances, he wasn't about to let go of that sandwich:

It's a rare occurrence, but they can have the same risk as any LiPo battery if not taken care of properly. 3rd party batteries could have been a possibility, but I'd be speculating.

It must have been a pretty good sandwich...

It is a pity that most of the advice given in that report is pure BS. LiPo batteries may catch fire, they do not explode. And the guy advising using the right battery matched with the 'right sized' charger is full of it too. Seeing the item was about a DJI battery, the charger is automatically the right size.

Talking about DJI batteries and appropriate chargers, made me think of Solentlife, and his using alternative chargers, that balance and override the intelligence quotient.  


I only hope, that who ever had this frightening experience isn't jaded or scared off from enjoying RC hobbies. This has to be a once in a lifetime experience, one in ten million... Much like winning the lottery.,
Only with bad luck though. ;-)

Is it only during charging the intelligent flight pack, that over considerations should be made?

This here is interesting. Looks like after a bath the battery seems to be a continuous hazard.
I'm wondering how to properly get rid of it:

Maybe just take it out into an open area and throw it in a campfire?  Once it has burned it will be safe. It would be exciting.

I beg to differ. It may not be an explosion compared to C 4 but it can explode as any container under pressure can.  It happened to me with a Li-ion battery. It was one of those compact car jumper batteries. After the car started the battery began sizzling and I went to disconnect it but it exploded and caught fire just as my arm was over it. Had some burns and bits of plastic embedded in my arm. Fire extinguisher put it out but they sure do make a mess.

Heavy duty Li-on cells typically have a very thick metal housing to protect them from impact damage. These can hold a HUGE amount of pressure before bursting, as you discovered the hard way.

Flight batteries have a thin foil covering the cells, so they tend to rupture before there's enough pressure built up for an explosion.

Whether Lipos explode or not depends on how you define the word.  IMO, the word explode is a good word when describing ignited liipos.  It's a pressurized ignition which is why lipos should be stored in a well-vented flame-proof container which should be kept away from other things that may ignite.  Know that upon ignition, the flames will shoot wildly out of the vents.  The fewer the vents, the more wildly flames will shoot out.  

In addition, if I may borrow a quote from Maximum PC's July 2002 issue:  "If the lithium inside the battery comes in contact with water, it can mess you up bad ..."

All right, I will further qualifty it and say the batteries used in DJI aircraft do not explode. The word 'explode' is a favourite term used by the media because it confers a bigger incident than actually occurred. In other words, alternative facts', the new Trump-esque term for media lies.

That's good to know.
