Do you really think there are tons of dodgy Chinese companies producing battery cells? A notoriously technically difficult, capital intensive and above all massively competitive business with tiny margins unless you are running the absolute best process at enormous scale?
No. There is just a handful of companies producing cells at reasonable scale and cost. Pretty much every cell you can buy from Alibaba (which is almost certainly where these e-bike pack makers are buying from) come from just 7 companies: CATL, BYD, EVE, CALB, Gotion, Sunwoda and Farasis.
All of these companies make high quality cells and these are definitely the only ones with a good enough price/performance to shove in a hand-made e-bike pack and make a profit.
This notion that Chinese batteries are somehow bad is ludicrous and the lengths people go to state as fact something they clearly have no experience with is intellectual dishonesty at best.
- infecto 3y agoI can see you are very passionate on this topic. I did not realize in the article that these shops were actually making individual cells but the rather the complete pack. My notion was that the complete pack may be safer than complete packs coming from china under generic fake names. Thanks for clearing it up. You clearly have a lot of experience in this area with incredible honesty but low capability at following thoughts.
- dghlsakjg 3y agoThe fact is that there are demonstrably under-specced batteries being sold. (https://www.youtube.com/watch?v=qMZuHMlRw_0&t=579s https://www.youtube.com/watch?v=qMZuHMlRw_0&t=579s) Is this just a case of people buying reputable batteries and selling them under their own brand name with higher specs? If so, why do these 7 manufacturers make bad batteries? Clearly there are plenty of badly made cells out there, so I think I'm misunderstanding something.
- mbgerring 3y ago> Do you really think there are tons of dodgy Chinese companies producing battery cells? Are you serious? Yes, obviously. Spend 5 minutes on Alibaba looking at the panoply of companies selling cheap cells, and reading forum posts from people who build their own batteries unfortunate enough to buy those cells.
