Well, its time for me to buy a new pair of batteries for my segalei 150w. My sony vtc's still run good but they're old, had em since april. Its safe to say, Sony VTC's were the battery kings of the 18650 realm, but now they're out of the game. With so many rumors of fake vtcs out there, its not worth the risk of trying to look for antithetic vtc's. What I want to know is, who is the new battery king, or are they all pretty much the same performance wise? I heard alot about the mxjo and the samsung imrs... Whats your opinion???
