I don't get it. The article reads like the company had a demand for 52V packs, so they built a bunch with shoddy construction, then blame it on the fact that it's a 52V pack when they failed? Is that it? Not sure what to conclude. Or are they focusing only on Hailong packs?
I don't get it either. But I noticed that "the company" from the article is also the same company that started this thread. I'm calling something on that. A quick perusal of "the company's" website shows that they are a dealer of Bafang mid-drives and not much (anything) else. Bafang mid-drives probably don't have much tolerance for voltages above 48V but that could never be the case across the entire spectrum of EV's.
I have to think that 48V batteries could be made as badly as the examples of 52V batteries given. I am a relative newcomer to the actual planning and execution of an e-bike build but I have had an interest for years. There are more ways than just cramming 18650 cells in Hailong and Reention cases. What about 52V (58V) tool packs? What about battery packs from electric cars? What about batteries built with 21700 cells? What about batteries of 52V, 60V, 72V and more, handbuilt (with love) by skilled fabricators for their own use or limited sales???
Yes, it sounds like 'this company' has an issue with 52V packs and want to use their positioning in the industry to push an agenda. Of course I could be way off base. I would love to be proven wrong actually.
