After 3 years, I've been thru Ego batteries, E-powers, Grippers, EGO VV and a telescoping mechanical. I've settled into using the E-power because of it's size and duribility, EGOs are too fragile. I don't want to carry a "fatty', not pocket friendly. Even a mech with an 18350 is too heavy. I don't care about VV/VW - a 1.7 coil at 3.7 is just fine. Is there anything out there in the 14650/14500 range with a top-fire button?
