Hello, I'm not new to vaping but i am new to this forum. Anyway I was just wondering how long do 14500's usually last? I've only used 16340's and 18650's and only bought mods that uses those kinds of batts(Saber Touch, mini GLV2, Provari,Omega and Reo Grands). And since I'm happily vaping at 3.7 I was thinking about buying a Reo grand mini. Any estimations would be great. Thx
