They look like standard 1865 cells but obviously not high enough res to spot the manufacturer. I would imagine EVE though. CATL is too hard to get a hold of but EVE Grade A is still pretty easily available from Alibaba.
EVE cells are also used in newer Ryobi power tools, it's worth pointing out: https://www.reddit.com/r/ryobi/comments/oxn53g/psa_ryobi_is_...
But you will find articles and sources online referring to them as 1865 cells, like Wikipedia.
"An 18650 battery[1] or 1865 cell[2] is a cylindrical lithium-ion battery common in electronic devices"
https://en.m.wikipedia.org/wiki/18650_battery
I imagine Tesla calling their new battery a 4680 (opposed to a 46800) also leads to this usage.
