Good luck, I havent had much luck with the trustfires latley. I got a set of the 18650's that where pretty lack luster and a set of 14650's that where about 60% of their rated output. Not to mention being labeled as protected on the wrapper, they are in fact not protected.
My 1.5 year old (heavily cycled and abused) flame trustfire 18650's from DX perform better than the last 2 batches of brand new ones I just got recently. Cycling them only made things worse for the new cells... not better. I can say that I'll never buy another one unless something amazing happens to improve them. Reverend Jims panasonic 18650 deal blow these out of the water at 1/3rd the cost.
I have 20 Trustfire flame 18650s that are about a year old and they are great except the 2 I got with the bad protection circuit.
Rev Jims batteries are the bomb and I have enough to last me a life time.
I was just hoping to find some 18350s that performed better than the ultrafires, the bestinone 18350s put out some serious amps but they don't last long. I was hoping to get the amperage of the bestinones and the lasting power of the ultrafires, so I guess I will be the guinea pig and see what these things can do.
I got 20 of Reverend Jim's batteries and they have been awesome. I, too, am interested in how these shorter 18mm batteries perform. By the way E, I still have not fixed my F15. (swamped at work, preparing to move, etc.)
