    To prevent any confusion with the eGo-type "batteries", I use the term "cell" here to refer to a single 18350, 18650, 26650, etc.

    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 says "max discharging current" 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 "40A" Enook has a ludicrously exaggerated current rating and an exaggerated capacity rating, it is only a 10A 3000mAh cell. At 40A continuous, it delivered only 31mAh down to 3.2V.

    Basen did the same overrating with their 40A 3200mAh cell but they used a rewrapped Panasonic. Both are among the most overrated I have ever seen...shameful.

    This Enook's appearance is identical to the 10A 3200mAh LG MH1 but it has a lower capacity than the MH1 and performs worse. It seems to be a lower grade MH1.

    I am rating it at 10A and 3000mAh. The 18650 ratings table has been updated to include this cell.

    Comparison to the LG MH1

    Pulse-Current Test Results
    No pulse tests were done as this is an MH1

    Always Remember
    - There is no 18650 that can have a factory/manufacturer rating over 30A.

    - There is no 3000mAh 18650 that can have a rating over 20A.

    - There is no 3100mAh-3500mAh 18650 that can have a rating over 10A.

    - There is no 18650 with a capacity rating over 3600mAh.

    • At 10A continuous this cell delivered less than 2700mAh. This is terrible performance for a high internal resistance 3200mAh cell at 10A so I am rating it at 3000mAh.
    • At 40A, the cell's rating, it delivered only 31mAh down to 3.2V. Clearly, this is not a 40A cell.
    • I am setting a CDR of 10A for this cell. While operating any cell near its rated maximum current level causes damage, I would expect ok cycle life at 10A continuous.

    The shame bell needs to be rung for the whole Enook range of scumbag re-wraps.

    This really is a shame as new vapers could believe their numbers and be in a world of trouble
