This is an 'FYI' for those who have said here, they wanted to try something more than an eGo but don't want a bulky eVic or Provari. It's in between using the 16650 batt - larger than an eGo's batt but not an 18650.
cignot has them in. ecigsupply has them listed but "out of stock"...
I don't have one. I'm staying with the eGo-c upgrade batts, but I did get an iSmoka IGO (pretty sure Joye made this too), which is the same size as the eMode. I still prefer the eGo-c's. The eMode has VW capabilities that the IGO doesn't.
