Found my first #StreetLithium in a long time (since the Quebec ban on flavoured vapes). This one has a large screen(!) (FP-144HSV03B on the flex connector) and a rechargeable 1000 mAh LiPo (but not refillable). The PCB is partially coated (nail polish?) making the chips hard to read, but the processor is a CMS32L032 ARM M0+. One of the other chips must be the flash, and the test points are exposed. (H/T @bornach )
I've collected a handful of examples of #streetlithium and they've come in roughly 3 distinct sizes. Small, medium and large.
Small have about 1Wh of capacity.
Medium has around 2Wh.
Large has 4-5Wh.
They all seem to work fine, though some self discharge from 4.2v to 4v before settling.
I have no idea what I'll use them for, but I like that they're in my parts bin to be used rather than landfill.
Another street lithium find (my 3rd so far).
This one only claims 0.6ah capacity, I'll test it soon to see how close it is to that.
2nd street lithium found!
This 18650 was found on the ground next to a bin in the high street, no vape casing nearby. I'm not sure what it came out of but it was almost fully charged when I checked, It looks like it holds pretty much it's stated capacity.

Electronics youtubers have often mentioned you can harvest rechargeable batteries from discarded single use vapes. It sometimes sounds like they're all over the floor and easy to find. I had not see a discarded vape until yesterday when I found my first.
Testing the battery shows it has a 1.1ah capacity.
