"Bench Test Results: Vapcell Purple 3100mAh 35A 21700...appears to be Samsung 30T, an incredible 35A battery.

Bottom Line: The Vapcell is identical in appearance and even better in performance to the Samsung 30T’s I tested one year ago. Perhaps they tweaked the chemistry of the 30T since my test of it or the samples I tested then were a lower grade.

The 30T, and especially this rewrap of it, are incredible performers. They easily hit harder than any other cell available to us and are a great choice for unregulated or regulated device users at higher power levels.

I am rating this Vapcell at a cool-running 35A and 3000mAh, same as the Samsung 30T. The typical capacity you get in use could be higher but the rated capacity is 3000mAh."
