Ownership verified by DX A deal that can't be beat.

Pros: Great capacity.
Good looks. (I like blue more than grey)
Protected.
Fit all lights I have tried.
I think the wrapper is better than UF brand.

Cons: Of the 6 or 8 I have, none will make the light go GREEN in the DSD charger.
At first I was REALLY worried about overcharging, but then I thought about it for a while.
Instead of going green, the light would start to flash like there was no battery in the charger.
I measured at the charger tabs and it had stopped charging.
The cell just caused the charger to think it was empty, instead of done.
I guess this isn't a huge con, but I was worried for a minute.

Other Thoughts: Better capacity and more efficient than using 6v to run a 3.7V led.
I wish DX would list max discharge rate.
That would be really nice.

Bottomline: I can't find a better battery for the price.
If you can then please start a thread.

Pros: Great cells, fits very nicely in my Aurora WF-600 (BOUGHT FROM DX!!), my Jet III Pro ST and now i want more lights that use 18650s. The runtimes on these cells are 1hr 48 minutes on max on my Jet III (225 lumens), havent tested them to run till protection cuts in on my Aurora.
The protection circuits work well, have left these overnight in my Ultrafire WF-139 charger (BOUGHT FROM DX!!)with no fears at all.
The cells come off the charger and popped right into the flashlights and are not hot.

Cons: None at all, everything is great!

Other Thoughts: Good for flashlights, and anything else that could use 18650s

Bottomline: Get these cells, this is the 2nd time i am purchasing them, now have 4 of these and may get more as i get more flashlights.

Pros: Good battery, works well in my flashlights. I get about 5-6 hours of run time. They fit well in the battery tube, although one was pretty tight in the tube. They cut off around 2.72v in my experience.

Cons: A little expensive, but all 18650 batteries are. The coating scratches easily.

Other Thoughts: Good batteries that work well, haven't had any problems. They seem to be about 2400mah based on my charger, so pretty accurate capacity statement.

Bottomline: These are an excellent choice for an 18650 battery, hold pretty much the stated capacity (actually 2400mah in my batteries) and cut off at 2.72v so that they don't over discharge.

Pros: These battery's drive mine ssc P7-c flashlight for more than a hour.
Build quality is nice too!

Cons: Maby a bit expencive.
The melted plastic is a bit cheap around the battery.
more coulers should be fun.

Other Thoughts: You can use this battery's for P7 flashlights easy.
They can drive mine flash light for 10 min and after that they only gone down 0,08 volts

Bottomline: The first time you use this battery's they are around 4.17 volts when charged, after serval times of use and charge they are above 4.19 volts :)
