    While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.

    Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.

    If the cell has only one current rating number on it, or if it only says "max" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously.

    Bottom Line
    This Vapcell appears and performs identical to the great performing Sanyo NCR20650A.

    The Sanyo NCR20650A has a “rated” capacity of 2900mAh, a “minimum” capacity of 2950mAh, and a “typical” rating of 3100mAh. So while I always try to use just the rated capacity for a rewrapped cell for my ratings, 2900mAh in this case, Vapcell’s rating of 3000mAh can still be considered accurate. It all depends on which rating you use.

    I am rating this Vapcell at 30A and 2900mAh.

    Unfortunately, this cell has Vapcell’s usual paper top insulating ring so juice spills could damage the ring. Be careful.

    Two cells from Vapcell were donated for the purposes of testing. Thank you!
