Oh, interesting. Hoverboards. UL 2272 certification was created in response to all the hoverboard hazards. It certifies the safety of the electrical and battery systems for a hoverboard. Particularly interesting is the language on the site that refers to “high energy density batteries.” Indeed, these have become a new hazard similar to the hazard of gasoline, only they are even more dangerous.
