TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries (2-Pack)

-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.
