Not related to a dji drone but just something I want to share as it scared the life out of me. I had these little 1s batteries for a while. Not going into detail about what exactly happened but one started smoking so I threw them both outside onto concrete and they started pouring out smoke and acid everywhere. It was on fire for a very short period of time. I usually keep theses in a lipo safe but definitely not testing it again. I’m surprised how much damage a small little 1s battery could actually do. You can see in one of the photos how it ruptured down the center and on the side. Have a good one and stay safe.
