I was flying today, and on my last pack, as if pulled it off, I noticed it was warm and puffy! It was a 1s, and in my experience they don’t puff. My other lipos do that, but they are 2s and up. Has this happened to you? Pretty funny, if you ask me. Nothing like a good session of flight.
Some of my 1s batteries are a little fluffier that others… I keep an eye on them, but I still use them.
They can puff just like any other battery… but usually the sagging performance lets you know you have to stop before you get them puffy.
Some of my mylipo 480mah batteries are “soft and squishy” from being puffed so many times… (retiring them asap at this point lol)
