Well as it turns out the guy who was involved is so embarrassed he is refusing to share ANY more details about the incident.
The "picture says a thousand words", to steal a phrase.

Not with DJI drones. In fact, has a Mavic battery ever caused a fire while charging on the DJI supplied charger? Probably, but it's so rare it wouldn't surprise me if it's never happened.The LiPo advice that you call needless are posted by me now and probably in the future on any forum because in the Remote Control Hobby the BIGGEST cause of injury and or property loss is LIPO FIRE.!
So why not talk about it when the conversation arrises. You say you have no problems leaving your DJI batteries alone while they charge, and thats fine for you I suppose, BUT the subject picture clearly shows a couple of 4s -RC- batteries laying in ashes in a kitchen. These batteries look to have NO balance lead connected, NOR where these batteries charged well away from flammable materials such as all producers of these batterys clearly print on their labels.
This is where you are misinforming people. It assumes DJI battery assemblies carry the same risk as naked lipo packs. This simply is not true.Charge your battery as you will folks but unattended is just asking for a fire (wouldn't you rather be there the instant something happened rather than get told by the fireman.)
Assuming the battery didn't show any bulging indications, based on the picture I'm inclined to say that the charging might have been pushing too much current for the battery.Lucky there, the runaway lipo fires can be hard to put out, and the gases emitted can be very toxic.
Be interesting to know what sort of drone, but looking at the charger wiring, probably not DJI or other high end consumer drone.
Lipo fires are very rare in well made, hard cased batteries, and the DJI (and likely other brand) BMS's really do their jobs well.
Certainly there are cases of Phantom battery fire incidents, those might be just that much older, and possibly not as good a tech, but in years to come maybe older Mavic Pro, Spark, and other early drones will see batteries becoming more unstable in the battery chemistry, which can result in fires.
You don't take any chances do you?I store my MA 3 batteries in LiPo bags and put those bags in an ammo box. I suppose could charge in that ammo box as well.
and I charge my ebike battery in a metal toolbox on a concrete floor.You don't take any chances do you?
The typical output of the typical 30W dji charger is 5 volt 2 amp -THE USB SLOT- and that goes up to 5v 3 amp
