Bench Test Results: Brillipower Pink 2600mAh 45A 18650...ludicrously overrated, lower grade, not IMR

    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 has “45A max” on the wrap, which is an impossible overrating. If “max” is some sort of “pulse” rating it is useless because we don’t know the pulse length, time between pulses, and the criteria used to set the rating. It cannot be used to compare this battery against any other.

    The wrap has “IMR18650” on it but this cell does not use the chemistry associated with the IMR model number prefix. It uses the chemistry sometimes indicated by the INR prefix.

    Its appearance is identical to the Sony VTC5 but this Brillipower doesn’t perform as well. It appears to be a lower grade VTC5.

    I am rating this Brillipower cell at 20A and 2600mAh. Its maximum vaping amps (MVA) limit is 25A, limited by temperature and voltage sag. With all the other cells that are available to us this one is a terrible choice and earns a Do Not Buy recommendation from me.

    The two cells that were tested were purchased for that purpose by me.

    Pulse-Current Test Results
    Pulse testing was not done as this is a rewrapped VTC5.

    There's nothing 'Brill' about these

    Thank you for doing the testing, Mooch! It's so great to have a battery expert (well, several, but you really rock it out) on the site!
