This Cylaid is a slightly overrated cell with a useless pulse rating. It matches the Samsung 35E in both appearance and in performance.
While this cell has the claimed 10A rating in fine print on the wrap it has a useless 20A “max pulse discharge” rating on the wrap too. It also features “20A” in a larger 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 “20A” rating, or any “pulse” or “max” rating, is misleading and shouldn’t be used.
I am rating this Cylaid at 8A and 3500mAh.
My thanks to Cylaid for donating the two cells for testing! (https://cylaid18650.en.alibaba.com)
