Hi all, i'm new here. I ordered 8 prismatic cells from tewaycell on aliexpress and i'm not sure if they're ok. i ordered 8 x 310ah cells and they're swollen, i'm not sure how much swelling is acceptable for new grade A cells, but they seem like B grade maybe because there is some swelling.
Can anyone tell me from the pics? I measured a single cell at 72mm, the 8 are 597 so divided by 8 is 74.625, an average swell gap of approx 2.625mm, actually a bit more because i only divided for 7 gaps. Is a 1.4mm of swelling on each side of a cell ok? Is it normal for grade A new cells? Or did i get ripped off? I haven't done a capacity test etc.
Also are these safe to use? I'll need to compress them but because there is already swelling i'm concerned about squashing them.
I included the qr code but don't know how to decipher the code for a manufacturing date.
Can of wd40 included for scale, those two are front and back shots.
