My electric scooter came with those cells:

I could find nothing about those cells. Except for the Capacity and nominal voltage printed on them.
I need to replace those because they were deep discharged to 0V.
I thought it might be Kokam SLPB100216216H, but that doesn't quite fit. But those cells would have been what I would have chosen to replace those with. But Kokam cells are expensive and I could not find a good deal.
Then I found a pretty decent set of second life cells from a dealer who carries the same scooter. Those batteries are probably identical with the ones I got before but have yet another useless no-name label printed on them.
I suspect it might be those cells http://www.libatt.com/productview_79.htm The specs fit very well and the physical dimensions are spot on too.
But I don't want to make any bad mistakes here. I want to set up the BMS with the correct settings. Especially for charge and discharge rates.
I don't want to take to many risks with LCO cells. (The fact that I bought them used and I don't know their history already freaks me out quite a bit. I know some of those cells were once in their life discharged slightly below 2V! see https://endless-sphere.com/forums/viewtopic.php?f=14&t=95831)
I was hoping perhaps somebody here has seen those branded cells before.
If not I guess I go with the specs of those China cells.
