Panasonic Sanyo NCR18650GA 3450mAh 10A Battery

The NCR18650GA is Sanyo and Panasonic's and newest high discharge capable 18650 Battery, 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 flash lights because it's lower internal resistance allows these high forward voltage LEDs to remain brighter longer. This cell, like all lithium and IMR cells, should not be discharged below 2.5 volts. It competes with the LG MJ1 in the medium discharge, high capacity category that is great for things like e-bike batteries and electric vehicle batteries.
