Pros:Pretty powerful batteries. Able to generate 2.880 amps at 4.18v with my Aurora SSC P7.Protection tolerances are slightly wider than on the label (.1 volts higher & lower than spec), but still within safe ranges. The protection does indeed work.Fairly inexpensive.
Cons:They may be too long to fit some flashlights due to the protection circuit, but so far they fit all of the flashlights I have purchased here.Drab blue is a bit bland.
Other Thoughts:I haven't tested the runtime on these things just yet, so no conclusions positive or negative. I'm charging them with Sku. 06105, which does a pretty good job with these.
Bottomline:They're good batteries. I read the previous reviews and bought Sku.20392's to compare. They are both capable of producing the same amount of current output to the lights I have, for the time I've tested them.

Pros:its does the job, if fits in flashlight
Cons:first ones I bought some 1,5 year ago and they were very nice product but now I ordered some 3 weeks ago and they are gone wrong , cos they are 68 mm long not 65 as it must be , so they dont fit in my Trustfire TR-801 , but at least fits in Aurora AK-P7-4 sku.32589 whose body is longer, also build quality looks much worser.
Other Thoughts:first ones costed somewhere 10 usd now only 8 usd, but unfortunately not because so it usually happens after some time, but that they gone worser
Bottomline:not recommended

GARBAGE look for another cell

Pros:-nothing good about these
Cons:-horrible discharge rate - max discharge rate in a single cell SSC P7 direct-drive flashlight is only 1.6A (with an unprotected cell the same flashlight pulls 2.4A+)-ineffective specified protection - but PCB doesnt cut-off over 4.2v (charged over 4.25v before manually ending) or below 2.75v (discharged down to 2.5v before manually ending)-slightly long at 67mm and slightly wide at 18.4mm, maybe too long to fit in some devices-18650s by definition should be 18mm (wide) by 65mm (long) making them a tight fit in most flashlights and chargers - my unprotected cells measure 18.3mm (wide) by 64.8mm (long)-soft metal on negative side (covering PCB) - spring in tailcap leave round mar
Other Thoughts:-charged with http://www.dealtoworlde.com/details.DTW/sku.0936 (slightly tight because of the extra length)
Bottomline:Don't waste your money on these cells. Quality and performance is not the same as earlier versions which received good reviews. These just don't cut it in high power applications like flashlights. Get better cells for full potential performance out of your devices. Very disappointed with these cells.

Pros:it is rechargable so you can use it for a long time. i bought it with sku# 4151 and it works fine . i use it with Trustfire ssc p7 f15 flashlight and it works well.
Cons:battery might be a bit thick. I had trouble taking it out of my trustfire p7 but i don't know it its the thickness or the stickiness the tape packaging left on it but other than that they are great.
Other Thoughts:no tape packagin makes them sticky
Bottomline:great batteries, great price, rechargable... protected so it gives a peace of mind that they wont mess up you flashlight.

Pros:If they are performing like the old batch, it would be a run for money. It seems the quality consistency is off for the blue whereas the black and red are of more even consistency.
Cons:The old batch seems to perform much better than the new ones. It seems that after the price drop, you are getting inconsistent quality out of it. I have ordered these batteries at 3 separate times and the latest one are the worst. The latest only manages 600+-mah at 3A draw whereas the old batch manages 2000+-mah.
Bottomline:I guess the safer choice would be the red and black version of Trustfire. The latest batch seems to be able to work better under low load. Not recommended for high loading. The shrink wrap of the latest batch if of darker blue which is different from the old ones and maybe this suggest Trustfire has cut down on quality.
