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.
