Okay I understand that 18650 are used in laptops and tool battery packs so they are getting the most new technology. I have some of IMR cells that are good for 3000 milliamp hours and still support a 20 amp draw. I was just wondering if you guys think if the 18350 and 18500 will ever get some of this new technology. I mean an 18500 could easily be 2000mah and support 12amps. Obviously I prefer IMR cells. I know battery makers don't care about flashaholics but vaping is huge and those guys(me included) use some serious amps
