    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 “80A” on the wrap. This is so much of an overrating all I can do is laugh. Even if we consider the 80A rating to be a useless “pulse” rating it’s still grossly overrated. At 80A the voltage dropped to my 2.5V cutoff in a fraction of a second.

    The 4500mAh capacity of this cell is also exaggerated. It is a 4300mAh cell, at the most.

    The wrap has “IMR26650” on it but I do not know if this cell uses the chemistry associated with the IMR model number prefix.

    I am rating this Brillipower cell at 23A and 4300mAh. Its maximum vaping amps (MVA) limit is 25A, limited by voltage sag. Now that we have better 26650’s to choose from this Brillipower will be removed from my Recommended Batteries table.

    With all the other cells that are available to us, without this degree of overrating, 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 due to its overrating and Do Not Buy recommendation.

    @Mooch what was the length on this? This was one of the first 26650s I purchased and I remember it being hard to fit in certain mods...

    NVM, found it from your first review (66.3mm). Thanks for the retest results!
