The most balanced and succinct opinion I can give:
1. There aren't a lot of experiences to form an opinion from, but it seems people have generally been mostly happy with the cells they sell (dunno about assembled batteries). This was before any of the issues with honesty came to light.
2. The point person for English language Sales, Carl, is helpful, speaks good english, and seems like a nice guy
3. The company misrepresents themselves and is disingenuous, more so than even other Chinese resellers, and are shady by Western Standards, and, probably Chinese standards too.
4. They do not manufacture the cells they sell, even though they publicly and privately state they do, even when explicitly asked and pushed on the issue. Best guess they sell grey market CATL cells (at least the 271 Ah)
5. Their website, including the about section, pictures, and supposed corporate partnerships and deals, are plagiarized from another companies website. And the certifications they post on their website appear not to be legitimate and are likely forged
All that said, as I said in point number one, people have been not had issues with their cells as far as I know, and my interactions with Carl have been positive (apart from the misrepresentation). I wish they would be honest about their business model / role as a reseller, I had a pretty positive impression of them before learning of the misrepresentation and fraud.
(For the nitty gritty, read page 3-4 of
this thread, for a fuller picture, and to watch my impression slowly change from positive to disappointed, read the whole thread)
