I believe I can ship these legally using fixed rate usps boxes with this 3480 label attached for loose cells. I just shipped 100 cells in a medium sized box for 17$ and had lots of room still.
A capacity percentage would be based on the stated capacity of the cell (2.5ah) and zero right? so if a cell shows 2.4ah capacity on a one amp discharge from 3.6 to 2.5 (their stated voltage range) that would be 96% capacity and not based on the cell’s end of cycle life which I think is at 80% of initial capacity, right?
I just got a whole slew more of these and all show the same 95% capacity or better.
