Ok, basically what happened was that I plugged it in, heard it hiss for like 1/2 a second, and then immediatly removed it. Currently at 7.5 V (2cell). Can I use it for my maiden flight of a plane and then dispose of it? Thank you!
My understanding is that most of the risk of lipo fires comes during charging and discharging. If you decide to try charging it, do it somewhere fire safe with ventilation, like on a stovetop or in the middle of a garage floor, and in the fire proof lipo bag. I saw one person who said that they charged potentially damaged lipos at a low C rate, like .5c, to reduce the risk.
For full disclosure, I’ve never actually had one catch fire, so I’m just going off of what I’ve read on the internet (where everything is true). I hope someone with more experience chimes in. 🙂
