Guy makes “dodgy e-bike” from 130 used vapes to make point about e-waste (arstechnica.com)

Disposable vapes are indefensible. Many, or maybe most, of them contain rechargeable lithium-ion batteries, but manufacturers prefer to sell new ones.

To make a point about how wasteful this practice is—and to also make a pretty rad project and video—Chris Doel took 130 disposable vape batteries (the bigger "3,500 puff" types with model 20400 cells) found littered at a music festival and converted them into a 48-volt, 1,500-watt e-bike battery, one that powered an e-bike with almost no pedaling more than 20 miles. You can see the whole build and watch Doel zoom along trails on his YouTube video.

Yeah, disposable vapes should be made illegal, not only are they lowering the bar for the access because they're cheap and accessible to minors, not only because they are an e-waste, but because it wastes valuable lithium, also those are perfectly chargeable batteries, is a bit fucked up that it's more profitable to use rechargeable lithium batteries than something disposable

My evil side wants them to be more popular where I live so I can collect massive amounts of lithium batteries for free

That's because the global manufacturing industries have almost exclusively gone over to lithium-ion batteries. Disposable batteries are ceasing to be commodity items. It's seriously difficult to find a D cell battery these days.
