I ordered a nitcore headlamp and a 2 pack of 18650 batteries that came in separate package from amazon $70. I got them and as soon as I opened the batteries, it started to get hot. I burned my hand before I knew what was happening and almost burned my house down. I got the lamp for free from amazon after a call haha. A coworker of mine uses them in his vapor thing and one day, another employee said hey man, you’re on fire. His pocket was smokin. He was able to pull it out with a few hand burns and we burried it. Fast forward a few months. As I was walking in to hunt with my nitecore head lamp, I felt my forehead get hot. Had to chuck the lamp and it got scorched inside. Thankfully it was morning so I waited until sunup to keep hikin in. There is a reason you cant put them under a plane as well. Soon, I cant imagine you can even have them on a plane. Very high lumen output though for a headlamp.

I have 30-40 18650’s and have run THOUSANDS of charging cycles and haven’t had a single problem.
If simply taking them out of the package causes them to get into thermal runaway... they are most likely cheap Chinese knockoffs. Unbranded, budget batteries of any kind are a bad idea, and unfortunately lots of light and vape sellers cheap out as far as they can on the batteries. Vape manufacturers are notorious for skipping easy, inexpensive design changes that could totally alleviate the risk of thermal runaway. As an example, instead of charging a capacitor to achieve the needed voltage for the vape device, they typically draw extremely high amperage on the batteries. (Far exceeding manufacturers limits) this is why their products are well known for catching fire.
The restriction on batteries on planes is for anything lithium ion... it doesn’t matter if it is 18650’s, lifepo’s, lithium AA’s, lithium CR123 (think hearing aids size).
With properly manufactured cells, and devices responsibly engineered to use them, there is absolutely zero problem with running an 18650 as a cam battery source. This is especially true because trail cams are designed specifically to run with as low power draw as possible, meaning they will never come close to over drawing a battery cell.
