I just tested some Molicel P26A and P28A. The P26A average 2720mah. The P28A average 2780mah. In terms of performance the P26A is just slightly better than the P28A. Using these cells, I get about 40 lumens more than Sony VTC6. I also tested them in the Fireflies E07 and got these results:
Molicel P26A: 6640 lumens
Molicel P28A: 6300 lumens
Sony VTC5D: 6300 lumens
Sony VTC6: 5650 lumens
Molicel P42A 21700: 5600 lumens
I recommend P26A for performance and the VTC6 if you want longest run time yet with good output. Also P26A will continue to perform better than the rest along the entire discharge curve.
All of these cells perform better than the Samsung 30Q from HKJ’s comparator
The Molicel P26A I bought from Vapcell is the best 18650 I’ve tried. It is also recommended by Mooch as the best all around 18650. Surprisingly, the Molicel P42A, which I also bought from Vapcell was a major letdown. Not sure if Vapcell got a bad batch of the P42A. It outputs about the same as the Lishen LR2170SF rated for much less current. Edit: I just checked my 40T and 30T in the E07 and got similar or less output than the P42A. I realize it is because the springs looses resilience and doesn’t push as hard on the 21700 cells resulting in poor contact leading to lower output. The 18650 with the 21700 adapter is longer than 21700 cells so it gets good contact.
