Not sure what virually means either, but you can elaborate on that too. Your errors in spelling and grammar make me suspect you are a shill defending the alibaba sellers of junk lithium.
The reason I always buy CALB is **BECAUSE** of the Chinese government ownership in the company. Having the China government stamp on the CALB test reports is as good as the Canadian Mint's assurance of 4 9's fine gold in their coins. You're not going to get away from Chinese manufacture of cells except for K2 energy, who really only serves the US Government demand for LiFePO4 batteries made inside the USA. K2 is massively overpriced. So, I looked for the most trouble-free mfg. of LiFePO4 in China.
As for me selling cells, and having a personal motive in this discussion - if you had READ carefully, you'll note that I **BUY** cells, not sell them. I have another 64 cells destined for my next project that are on the way somewhere in the pacific ocean right now. The two ways I get my price down are #1 taking advantage of currentconnected's buyer, who is in China, and who buys in 1M quantity, thus getting the price discount and opening up a range of factory new cells people can't buy using alibaba. #2, I pay in advance when the order is placed, then wait patiently for them to arrive, just like buying from alibaba, except the person I'm dealing with is a US business that takes credit cards, has free shipping, and not a photoshopped alibaba storefront insisting on ali-pay. If you get a bad product from alibaba, can you just pick up the phone and call them?
i.e. You can get a low price on new CALB, provided you order in advance and wait. If you want something today, you'll no doubt pay web prices.
Comparing the NEW CALB cells I purchased from currentconnected (with a 10yr warranty and free shipping) to their "A-" grade 271 Ah CATL cells (with 30 day warranty plus extra to ship), it looks like the seller is clearly saying these are either used or reclaimed cells, they do not meet the factory spec, and they are already inside the US for fast shipping. I call it "Junk Lithium" regardless of who you buy from - those cells are so degraded that they won't make a decent pack. If you want a 48v, 16 cell pack, it will be limited by the capacity of the WORST cell in the pack, provided you have a decent BMS watching each cell's voltage. Also note CATL does not make a cell with a threaded nut or screw-in stud. After the cells are reclaimed, the 3rd party house laser-welds these features onto the flat terminals, which are meant for busbars. Or, worse, they drill & tap the aluminum terminal with only 4 threads before penetrating the hermetic seal, which lets the liquid electrolyte out and atmospheric moisture & oxygen into the cell.
CALB, on the other hand, made the -B version of their 230Ah cell just for folks like us who need to bolt-on busbars or cables. Those welds of the inverted T nut, with helicoil inserts in the aluminum, are done perfectly by machine at the CALB factory, not by a 14 year old girl in a sweatshop using an IR laser welder without any IR blocking glasses nor PPE. The only other mfg. that I know of who has a threaded option from the factory is Winston-Thundersky.
If people are ordering 271 Ah cells and getting 250-253 Ah in their worst cell, then they are worse off than buying a 230Ah CALB that tests at 245Ah because CALB always includes margin ABOVE their spec, just like battleborn did in the early days. CATL specializes in QUANTITY. CALB specializes in QUALITY that is good enough for aviation. Those worn-out 250-ish Ah CATL cells already have one foot in the grave, while the CALB cells are straight off the production line, into a wooden crate packed with foam slabs, and with the slowdown at the port of LA, they get here in ~65-85 days. Lastly, the CALB cells are thinner than the CATL was 300+ now 250Ah cells.
"A-" CATL says 271, but tests at 25x with a 30 day warranty (PLUS Shipping)
NEW CALB says 230, but tests at 245 Ah with a 10 yr. warranty (Free Shipping)
Which one would you choose?
