    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 cell is identical in appearance and performance to the 5-leg top contact iJoy and the Efest, Ampking, and EBAT 3000mAh 20700’s.

    This cell is double wrapped. While this provides a lot more protection from damage to the wrap it does increase the diameter of the cell a bit. For the two cells I tested the largest diameter was 20.39mm. It has a plastic top insulator ring which should resist juice leaks.

    I am pleased to say that EnerCig has rated this cell very close to what it tested out to, delivering 2915mAh. I am rating this cell at 30A and 2900mAh. This does not mean the EnerCig’s ratings are wrong. When the numbers are this close it’s all up to the equipment and the criteria used to set the ratings.

    Two cells were donated for the purposes of testing by EnerCig in Germany ( Thank you!

    Pulse-Current Test Results
    No pulse tests were done as this is the same cell as the 5-leg iJoy and others.
