This Nitecore is a 22A rewrapped cell with a useless pulse rating (see the Comments section).
While this cell has a 20A continuous rating in micro print on the wrap it has a useless 30A “max pulse discharge” rating on the wrap too. It also features “30A” in a huge font which many people will use as the cell’s rating when shopping or when a vendor displays it on their web site. For these reasons I feel the large “30A” rating, or any “pulse” or “max” rating, is misleading and shouldn’t be used.
I am rating this Nitecore at 22A and 2100mAh. It appears to be a Samsung rewrap and might just be 2000mAh cells that test well for capacity. Its performance is similar to the 20R but its appearance isn’t a perfect match to the 20R’s I have.
The two cells that were tested were purchased by me from IMRBatteries.
