Bottom Line: This Efest is a rewrap, identical in appearance and performance to the Panasonic 10A/3300mAh NCR18650GA. Both the Efest's current and capacity ratings are exaggerated. At 20A continuous this cell gets hot enough to boil water, 111°C. I am giving it a 12A/3300mAh rating since at 10A it runs cooler than the average temperature for a cell at its continuous discharge rating.

Another eFest nightmare. I think it's very unethical and dangerous what their doing. Batteries exploding in vapers pockets is all over the news when it happens and here we have a company selling inferior batteries passed off as high end. I have mech mods and cringe when I think what will happen to someone who builds low expecting their eFest to perform
