I don't care about hoverboards, but a great side effect of their mass production is that you can get a pretty decent brushless motor now for very cheap. I also saw a video about a hack you can do to make it run better at higher RPMs. You can get one of those hoverboard motors for like $30 on ebay and pair it with a $25 ODrive clone from aliexpress. Its good for probably 10 nm of torque at 36v 10a.
I see a hoverboard at my apartment dumpsters practically once a week. I rip them open for the battery pack, its always a stack of 18650s. I guess i should start collecting the motors too?
(you probably already know) but this is common in a lot of battery packs. Batteries for power tools are good sources for the 18650s too. I never checked but I saw someone open a Tesla car battery and they look like a bunch of 18650s inside too.
I refurbish my power tool batteries instead of buying new ones because it is so easy.
