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.
