From the pictures I get the sense this guy knows what he's doing. Sure his shop's a little dusty, and that fume extractor is maybe a little ghetto (better than my aquarium filter duct taped to a fan though). It's hard to tell what those grey cells are being used in the pack, which is probably most important factor, but the construction of it appears solid. It's also evident from photo that he is disassembling a damaged pack. See the missing row of cells at the top, and corrosion on the bottom in this photo: https://149346090.v2.pressablecdn.com/wp-content/uploads/2024/03/NYIMASLAULA_ROW_Bali_Ebike_8587-600x900.jpg https://149346090.v2.pressablecdn.com/wp-content/uploads/202...

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 would be my guess too, possibly INR18650-35V, which seems totally cromulent for an ebike. 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_using_chinese_18650_cells_in_most_of/ https://www.reddit.com/r/ryobi/comments/oxn53g/psa_ryobi_is_...

  I think you mean 18650? Unless 1865 is a new battery standard that has 10x the capacity, in which case EDC light with 1000 hours runtime here we go!

    They are indeed called 1865 cells too. The 0 at the end, according to some sources, indicates the cylinder form factor; I couldn't find a definitive reference for this though. 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 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.

      Yeah it's abbreviated sometimes and I'm lazy. I should have added the 0 for clarity.
