I am sure you will get that with the VV REO.
From talking to Rob last night he is going to set it up to use a lot of different batters.
We talked about the IMR 18350's last night and it looks like he will try to make the VV Grand work with as many batters as possible.
Awesome! I was hoping to get away from stacking batteries all together, but if I can get a full day of vaping from stacking 18350s I'm down.
