Today I had an eye-opening incident while charging a LiPo battery. It was an SLS Quantum 4S 1500mAh 65C from StefansLipoShop, but they no longer seem to sell this exact type.
As usual I charged it using my iSDT D2 smart charger. I heard a strange popping noise and was not sure at first what caused it. Then I saw this hanging from the charger.
I immediately unplugged it and put it outside on the balcony. The cells were noticably hot to the touch. If I hadn’t noticed anything I think the charger would have happily continued until a more catastrophic failure would have happened.
After building nicer storage boxes for my batteries I’m now thinking about only charging in a can as well!
