Sorry my guy but you got ripped off.. sad but this has happened to me before now I buy direct from EVE only, pay more but its good stuff.
Can you Send a private message ?With Alibaba I would usually say there will be a fair resolution, But this can be very complicated, and I can't offer your next steps. What I can say is it will be watched by many.
So dumb question, but how much of an issue are swollen cells really beyond the A grade vs. B Grade argument? The guy who got me interested in solar had cells more swollen than those in the pic, but they maintained rated capacity and had been cycled many hundreds if not a thousand times when I saw them. Is that abnormal for swollen cells or....?
In my experience once cells are swollen irreversible damage has been done to them.
All the cells declaring CATL,100% grade B!Bought some cells from Alibaba, they said they were grade A CATL but most were scratched up, minor dents, and a few were a different shade of blue, slight bulging, is that normal? At least the QR codes were intact, currently load testing, are these CATL or someone else?
Can i ask what app / hardware your using here ? Also of course gutted to read your problems.Just finished the capacity test, after parallel top balancing at 3.65v for several days, I hooked it up to a 12A load and it ran for 25.5 hours and came in at 302AH, toward the last few minutes of the test cell 4 was way lower, should I just set the BMS to cut off at 3.1V and max charge of 3.6V? I will be using this in a sprinter van, so would it be better to use 20%-80% of the battery pack?
PWOD and Sanben are the same Grade B or G junk, selling at Grade A ($185 ea to my house) prices. I received 10 out of 16 swollen, advertised as 320 aH, tested between 305-316 aH, IR range= .22-.26 mohm. Steer clear and no, swollen cells are not normal for Grade A. Only cells that did not meet factory specs, were overcharged, charged with a cheap lead acid battery charger or over six months of daily use on them are swollen.
Yep. Same Grade G (Garbage) they sent me. By the time I received the cells, they had already closed everything out and said I had received them two weeks earlier. When I did complain on Sanben and and Liitokala’s store message center, it was the same old BS...our cells are perfect grade A, meet specs, swelling is normal, you need to test more, etc. The worst customer service I have ever received, next to Rareelectric on Amazon.Yes, exactly same problem what I received. All batteries with small QR code that is painted in the corner are refurbished old cells that are considered JUNK. Did you open a dispute ? Any success ?

Seller created a text that say only lies, they say all is normal and all is fine.
