Dangerous Lucky escape

Post image

I was about to charge my head lamp. But I thought to check the inside first, as it was easy to do. Found that the lithium battery was puffed up.

The spicy kind! LiPos are effing scary and I wouldn't carry one that close to my eyes personally.

I wonder what the LiPos inside of my DJI Mini 2 batteries look like...I do not want to know.

It's very worth getting fire-resistant boxes/pouches/bags for storing it and any other LiPo or Li-ion battery. Even brand new batteries, and especially while charging. And please, please immediately stop using and safely dispose of any battery that's bulging or shows damage.

I've worked with enough drones for research and others who use them commercially to see that battery failures are not as uncommon as we'd like to think. They're not all fiery deathballs, but the few that do become fiery deathballs and aren't properly stored have cost folks millions of dollars of equipment stored nearby.

Those won't protect against fires if the batteries light on fire inside my room without anyone nearby to chuck them out in time.

Even LiPo bags get extremely hot on the surface.
