Hi Everybody,
I just received 16 272AH cells from Basen on Saturday. They were ordered as Lishen 280AH, new Grade A, matched set in December. They appear to be multiple brands re-wrapped in blue PVC by Basen, bubbles and all. The batteries have several different vent color/config (photo below). 4 appear to be CATL ("broken" blue ring), 5 another brand (continuous blue ring), and 7 Lishen (clear vent, no blue) as ordered. Does anyone recognize the continuous blue ring's manufacturer?

The package included a note from Basen stating that Lishen provided the cells to Basen without any wrapping, so Basen did it in-house. Plausible, except if Basen wrapped several different brands and sent them to customers as Lishen. Anyone else get the note and different battery brands?

The QR codes are there, partially tucked under a new top cover. Despite the vent differences, the QRs all share the same format: 08BCBPB119C0519CSA121651, 08BCBPB21AA011AAK1101784, 08BCBPB119B1319BWA210029, etc. All start with an 08BCBPB. Are these Lishen factory formats? What are the odds that different brands all share the same QR? I searched the web and forum and can't find any Lishen factory QR examples. Can anyone share some?

Regarding condition, the 7 Lishen and 4 CATL are resting within 0.010v or less, but the 5 unknown with the continuous blue vent ring are noticeably lower by 0.018v on average.
I've contacted Basen and would like to think that it's all a simple misunderstanding and these are all Lishen batteries, but between the re-wrap story and different vents, while sharing conforming QR codes, have my doubts. In addition, there are discussions noted in forums that Basen ran out of Lishen batteries in late-December to early January and was only offering CATL or others. I really don't want to combine different brands, ages, specs into one bank. Anyone else run into this?
--Thanks
