Bench Test Results: Brillipower Pink 5000mAh 40A 26650...comically overrated, very long, 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 “Max Continuous 40A ” on the wrap but this is a ridiciculous overrating. The “Pulse 85A” rating is completely useless. At 85A the voltage dropped to my 2.5V cutoff in a fraction of a second.

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

This is a very long cell, averaging 67.3mm, and will not fit in some mods. I do not have a list of which.

Compared to the Shockli Black 20A 5500mAh this Brillipower hits a little harder at the start but performs worse for the rest of the discharge. For low to moderate power vaping the Shockli is a better choice.

I am rating this Brillipower cell at 20A and 5000mAh.

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