The 26650 is more like a long C cell, but it is the biggest I am aware of. I built a box mod for it with a 2 C cell battery box from madvapes. Worked pretty well but I have since moved on to an Evercool mod using 2 18650s in the same box and get a much more consistent vape, with excellent battery life.
