    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    Cons:
    Batteries are rated 2500mAh but the real thing is around 2100mAh.

    Great near-standard-lenght cells

    posted by Vasfed0 on 01/28/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    The cells are exactly 65mm in length, which is standard for 18650 (650 stands for 65.0mm) and can fit where some others cannot. Good build quality Cells came in plastic storage case Capable of high-current Of course not 2.5Ah, but somewhere close
    Cons:
    They are unprotected, thus: dangerous if incorrectly charged/overcharged can stop function if deeply discharged

    Great 18650 cells for the price

    posted by Eudaimonium on 10/27/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    The batteries are different from other $8 level batts, in a way that the positive point is not sticking out of the battery, it's rather recessed in, and cell's finish itself gives a high-quality feel. The batteries came in a nice plastic box in which you ca...
    Cons:
    Ofcourse, capacity not exactly as advertised, but can we really consider that a con at this point?

    posted by lcys73 on 05/28/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    2000 mAh + according to my iMax B6. The strongest I bought so far.... Can power my laptop for 2 hours or more witch is pretty good I guess. Worh their price! THIS would be the one if you want to buy a laptop battery cell replacement.
    Cons:
    Hmmmmm....the biggest con is the PRICE.... I guess could be cheaper a little bit [ about 1-2 $ ] I found about 8% difference b...

    Great for an XML direct drive

    posted by Darrenm on 04/05/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    - UNPROTECTED!!!! - I get up to 3.2 to 3.4 amps on an XML C8 flashlight (which I am pretty sure is direct drive on high mode) vs 2.6 to 2.8 amps for trustfire flames. - See the video I have posted. - Some of my trustfire flames were also cutting out on high...
    Cons:
    - be aware, no nobbly bit on the positive end, so to best to use in a flashlight which has springs at both ends - I would tend ...

    Heavy duty batteries

    posted by JuhaniM on 12/24/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Capacity of those batteries is really good. ~2100mAh@1A continious. When 0.2C discharge is done, sometimes the real capacity exeeds original capacity. Internal ressistance is really good. Even better than those 2400mAh gray ones with high current draw. ...
    Cons:
    No cons. I have done around 100 charges and no changes in capacity

    100% reliable.

    posted by cyclist on 12/20/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    These are 100% reliable. Ive have probably bought over 700 of these and i have never had one faulty battery. The only way you can kill these is by running them empty below the recommended lowest voltage. These get used in P7's and single Cree lights and ...
    Cons:
    Batterys are great, but price is more than the protected ones! Should be maybe $1-$2 cheaper.

    True Rated Capacity, Definatly no protection

    posted by RBLAND on 08/04/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Just got mine today. -Did a discharge test at ~1.66A for 1.5 hours. (Basically 2.5Ah capacity on on the dot, which is QUITE GOOD for 1.66A current drain) Battery did get warm! In regards to the other reviews - these are NOT protected -Not much voltage drop ...
    Cons:
    -It looks like they are NOT protected under full discharge test - was expecting this - No positive *bump*. A blob of solder on ...
