A lot of times 18650s and 26650s are double wrapped. Once when produced, and once again when the PCB for voltage protection is added (they don't remove the first wrap).Way too much of a good deal. I got some 18650 trustfire batteries from aliexpress with a charger. The batteries were no where near the rating and when I took the wrapper off them it looked as if they were old cells that had been rebranded.
