    These tests below only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

    Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

    Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

    Any rating in my ratings tables can change at any time as different grade cells appear on the market or we get swamped with fakes. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.

    If the battery has only one unexplained current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.

    Bottom Line
    I am delighted to see the ratings on this cell. It looks and performs the same as the good cell wrapped by Aspire, Golisi, and iJoy for their 4200mAh-4300mAh rated 26650’s (when I tested them) but this Vapcell has its 32A continuous current rating clearly marked on the wrap and no “pulse” or “max” rating. This is fantastic and I hope more companies start doing this.

    I estimate this cell’s ratings to be 30A-32A and 4100mAh-4200mAh. As with many cells that are manufactured in China there is greater cell-cell variation than from Samsung, Sony, LG, and Panasonic/Sanyo. That makes it difficult to pick a single number for the ratings.

    Two cells were donated for the purposes of testing by Vapcell (Shenzhen VapCell Technology Co., Ltd.). Thank you!

    Performance Specs
    • DC Internal Resistance = 20.8mOhms (milliohms) average for the two cells.
    • Total energy delivered down to 3.2V at 10A continuous = 13.0Wh (Watt-hours) average.
    • Total energy delivered down to 3.2V at 20A continuous = 10.9Wh (Watt-hours) average.
    • Total energy delivered down to 3.2V at 30A continuous = 6.8Wh (Watt-hours) average.


    Comments
    • Vapcell paid a fee to be moved to the front of the testing queue, which currently has a 10-12 week backlog. This cannot influence my test results as they pay in advance, have no say about what is in this report, and I don’t care if any company never does this or donates batteries again. My reputation is a lot more important than any battery donation or payment.

  2. Thanks for the review. My dealer/neighbor Jon from Liionwholesale sells this battery and the Ijoy. I guess I can not lose with either one!

    I wonder what the Vapcells voltage curves would look like at 10A against the Golisi,Ijoy and Aspire?

    Thanks

    Compare them. :)
    Pick a voltage, perhaps 3.2V, and see what capacity each delivers down to that point.

  4. Sorry if I confused you. I do not have any of the batteries[yet]. I was just making a statement.

    I see you compared them @ 30A . I was wondering what the graph would like like at 10A?

    I am not a vapor[I hope u do not kick me out!]. HKJ did not test this cell so I have no way of knowing how it acts w/ loads other than 30A.

    Thanks,,,,,,,,,

    Check my continuous current discharge graphs for each battery for the 10A discharge curve. Pick a voltage and note the capacity that battery reached at 10A at that voltage. Do that for each battery. The highest number indicates the best performer.

    Wait...the other cells you mentioned are the same battery as this one, as mentioned in my test report. The exact same battery. There is no difference between them.

  7. The 30A graph shows the Vapcell sagging a lot more in the beginning and then catching up to the others.That seems like a difference to me..but then again with the vaping regulator that a member explained to me this may not matter. For modified flash light guy who is a fish "Out of water" here[!],,,that can make a difference.

    What I am looking for is a constant current graph like you have for the 30A that also includes several other batteries for comparative analysis.Inclusive to the 30A would be 10A/15A/20A. Basically a comparator like HKJ has.I am addicted to that! I can compare numerous Amp draws for two different batteries,pick the winner and bring in another challenger!

    Thanks for your time Mooch

    ,,,,BTW,,,How did you get that nick name?Were you always drinking someone else's beer?!!

    Hmm...same cell though so probably just cell to cell differences. But I’ll check.

    A comparator is on the wish list but it’s been there for a year so I don’t know if it will ever be done. No time.

    Mooch has nothing to do with the dictionary definition. It is one syllable from an unfortunate grade school nickname that was rhyming off something else.

    I believe you may have to ask a mod to do it? Could PM one and ask?
