So far as noted no problem is rechargeable cars but there have been too many Li ion battery failures including a B-787, hover boards, power tools, smart phones, etc.
In my view the primary failure with the B787 was the FAA's decision to undermine their own mandate by allowing the manufacturer to self-certify the design. Those fake hover boards were completely unregulated rather than professionally underwritten, so it's no surprise they had sloppy designs and insufficient safety measures. They probably should have been blocked at the border but I guess burning down people's homes isn't seen as a problem worth preventing.
Well, if you guys joined the rest of us cool kids and used an iPhone, you wouldn't be in this mess.
Not sure if this was intended as a joke but Apple has had their own battery failure recalls in the past. My first generation iPod Nano was one of them.
