You asked and we got it done...we now have e-POWER Replaceable Battery eGo spare kits available for use with 14500 batteries.
The size is the same but the tubes now accept the unbiquitous 14500 battery. Find them in the e-POWER section. Right now they are only available as spare e-POWER kits and that means they include the tube in all three colors, new black rubberized paint finish, stainless steel and titanium. You also get a matching cone and the e-POWER 3.7v regulated PCB switch.

These also can accept a 14650 battery but it takes a little force to push them down into the tube and then screw the switch into them. But the factory demoed for us and it can be done sucessfully (of course, for ease of use, the 14650 tubes, also available on the site in spare kit and full kit form, will be easier to use for 14650 battery insertion)
