I've got pictures of one that also is labeled BAK 18650C4 which is a 2100mAH cellbut it tested 2623mAH so it appears to correctly be a LS cell:

Hi. How is everyone? I am new on the blog. I am starting to sell electric scooters and i would like to understand better about batteries. Would this model be good or not? And why?

It's not very good in my testing. It's a relatively low capacity and degraded quickly under high discharge/charge conditions which makes me believe it would have poor normal cycle life.

Can anyone tell me why the cells say 2150mah? As well as does anyone know the amp rating?

I have now gotten three of these cells and all three of them say 2150 mah yet they all test at at 2600 mah or higher which is what the LS cell claims to be. This time I also noticed that even on the battery pack itself it claims 2200 mAh. And then when opening up the pack it is wrapped with a blue wrapper and a sticker claiming 2200 mAh. And then obviously finally when you get down to the green cell you can see the 2150 mAh markings as well as the ls markings. This is one of my weirdest encounters with recovering cells.
