Relevant: "Louis' front door goes BOOM courtesy of UnitPackPower battery" https://www.youtube.com/watch?v=JCaDz_2YcGQ https://www.youtube.com/watch?v=JCaDz_2YcGQ Lithium Ion (and especially LiPo) are not to be trifled with, small things might matter (such as whether the battery is under mechanical stress, dented or bent). I would never want a large battery from a non-reputable supplier around my home.
