Also,which charger, nitecore I4 or LUC v2 ?
Thanks! I got an extra 18650 tooI'm not a fan of stacking any batteries, go with 18650.
I second the 18650 and Nitecore.
Make sure you get unprotected imr batteries for the vamo. It has a built in protection circuit. They don't work well with the protected ones and will cut off.
i have two vamos and p.busardos reviews indicate that two 18350s enable a measurable although imo undetectable advantage over one 18650. i use efest batteries and charger. i have sony us18650vtc3 and the vamo turns itself off occasionally. high end vendors are carrying AW and efest. you decide. happy vaping!
These say IMR but nothing about protection
