My dad used to buy disposable vapes. I decided to take them apart just to find rechargeable li-ion batteries. By the way, in many of them there were quite thin wires and some of the insulation was visibly burned, looks quite dangerous.
Similarly there are some single use power banks. DiodeGoneWild made a video about those and also how to recharge them.
Just a stupid waste of batteries.
I like to tinker with things. I wanted to see if I could hit a weed cart powered by my phone so I bought a bunch of cheap 510 batteries with temp select from DH gate. They were all the same brand, same seller, same packaging. Inside was a different story though. All the batteries were from different manufactures with capacities different from what was listed.
