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

    Pros:

    -They are somewhat slimmer than my grey TF18650 2400mAh (1 grey cell doesn't fit in 2 of my flashlights, but these black/red cells have no problem at all)

    -Genuine capacity of at least 2400mAh, hold their voltages extremely well at high loads.

    I have a 5A MC-E installed in the RC-G4 torch with a 1400mA driver (7135 chips). From the runtime tests, the grey TF18650 2400mAh could only hold full output (1.4A current draw) for ~35' then the light went into direct drive mode. However, when I used this B/R 2400mAh cell, the same light ran at full output for ~102 mins before a sharp drop off.

    -They look pretty good, with the red and black and flame and everything :P, wrapping doesn't seem too durable though.

    -Protection circuit seems to work, my TK30 (runs on 2x B/R TF18650) shut off automatically during its runtime test.

    Cons:

    None at this point

    OtherThoughts:

    These new TF18650 batteries perform so well that you don't need to pay for more premium Li-ion cells like AW, unless the reliability of those cells are of paramount importance.

    Bottomline:

    I'll probably buy only these cells in the future for my 18650s needs, they have the best values and quality here on DX.
