NiCd and NiMH can also output huge amounts of current when shorted. |

I have seen NiCd sub-C cells shoot out flames about 5 inches long. This was in a radio controlled race car which draws huge amounts of current. Who knows how the owner treated the cells. |

Li-Ion cells contains flammable electrolyte and are suspect to thermal runaway when shorted. Sorry about repeating myself but those who say "scaremongering" are advised to read more about 18650 Li-Ion cell failure modes and statistics of accidents in US alone: https://www.usfa.fema.gov/downloads/pdf/publications/electronic_cigarettes.pdf Affected individuals most likely are suing manufacturers out of their money and mind, this is main reason of disclaimers and warning videos. I don't mind that they are dumbed down because many people are indeed that dumb while using dangerous stuff. |

It’s common knowledge among electronics experts that lithium ion cells have insanely high short circuit currents, far more than NiMH, and are much, much, much more susceptible to catastrophic damage resulting in fire. (Fire is NOT a common failure mode in NiMH cells, even if it’s possible.) I don’t think it’s fearmongering in any way to warn consumers away from bare LiIon cells, since most consumers have no idea just how badly a mishandled LiIon cell can behave. As for Rossmann, I don’t understand why people give him so much attention. He’s a whiny windbag with a chip on his shoulder. I do agree with him that the USA has become cripplingly risk-averse, but I don’t actually see this particular instance as being evidence of this. |
