Question CALB quality slipping?

Two recent cell deliveries that came with a large resistance spread, some sloppy looking cell construction, cells out of sequence, and questionable crating, have me wondering if CALB cell quality is not as good as it used to be. My order from three years ago was much more closely grouped and packaged better than these two orders:

Has anyone else seen similar resistance spread and sloppy cell construction?

Can you quantify your observations?

It's all in the linked thread, basically my cell resistance range from three years ago was .28-.35 for 100 ah cells and the new shipments came in with twice as large a spread, plus some sloppy looking cell construction:

My appologies for not reading the linked thread.

The resistance/capacity values being referenced to,is what they supply with the cells as a data log?

Not having read the whole thread that you linked to, Did you verify the data?

My cells came with a sheet listing the serial number, tested capacity, and tested resistance for each cell. I also had the data sheet for the entire shipment of cells, it was an early order for EVComponents. All cells were more closely grouped than the two recently reported deliveries mentioned in that thread, and the resistance numbers were lower overall for the shipment three years ago compared to the two recent shipments in that thread. I also saw none of the reported sloppy cell construction that they mention, and my shipping crate was of good construction and the packaging was tight and proper.

Looks that way. Wonder if it is temporary due to part of the production line down or similar. Quality was looking good with the shipments to diyguy and electriccar. Sorry to see this. I think I would ask to have some replaced to narrow the spread.

I got mine from Keegan last fall and they were tightly grouped and well packaged.

FWIW: I don't see the 130ah cells listed on the Chinese (company) website in either the blue, SE or the (newer?) gray, CA series. Does anyone know if they're still being produced or are they discontinued?

Did you get them from the CALB factory in LA or did you order them from an obscure site from China? Sure they are CALB's? Seems a bit odd that CALB would sell you crappy cells and sell you poorly built ones as well. I'd expect to see that from Hi-Power maybe but even they have gotten better. Odd indeed.

I don't know where they got their cells, I assumed from Calib power, the US CALB distributor.
