Edited.-

Despite Henrik's graph would probably match better if the NCR18650BL cell were have been tested on the newer 4-wire battery holder test station, capacity still does not match even if cell curve shape does.

So it is not an NCR18650BL. There are cells Henrik still have not tested, the one Sofirn is rewrapping could be some 3100mAh 0.2C rated cell from some known manufacturer like an NCR18650A, or from another OEM.

Take care :THUMBS-UP:
