Haha, glad someone tried to guess! But nope, there are several cells that beat the VTC5. Two that come to mind immediately (that beat the VTC5) are the 25R and the VTC6, both of which run cooler and have a higher capacity than the VTC5. You probably haven't heard of the specific battery I'm thinking of unless you've worked a decent amount with batteries, though; it's not terribly popular with hobbyists (part of that, of course, is that it can be hard to get.)
