Comments:
This is one heck of a cell. You aren't going to come close to its capacity in any other IMR 18650. It destroys the AWs I have and the Bestinone.net cells I tested. It doesn't quite have the capacity of today's LiCo cells, but it holds voltage higher than just about all of them. The only competition are the Sanyo 2600s I have and there's nothing intrinsically safe about them.
They do get plenty hot during a 10A discharge, so I wouldn't use them at that rate, but so do my AWs (Which I actually haven't completed a full discharge @ 10A due to them getting so hot)
The 4.6A draw I got from the MF/UF test is the highest I've ever seen, it even beats an IMR 26650.
