This is Sanyo and Panasonic's and newest high discharge capable 18650 cell, rated for up to 10A continuous discharge. It is a good compromise between IMR and regular LiCo cells, offering lower internal resistance and higher discharge rate capabilities and higher capacity than IMR. This is a popular cell for high drain XM-L & XM-L2 lights because it's lower internal resistance allows these high forward voltage LEDs to remain brighter longer.
The protection circuit features a high-quality Seiko IC (made in Japan) with AO MOSFETs.
Manufacturer Cell Specifications:
These cells, like all lithium and IMR cells, should not be discharged below 2.5 volts.
