I have 3 vtc4's in mine and the battery life is probably around the day and a half to 2 day mark (I never let it run down that far and usually charge each evening after work). I vape at between 20 & 40 watts and I use less than a third of a battery from 7.30 am to 6 pm. I don't vape heavily at work but I do travelling to and from it. No complaints about battery life here
I've been using mine with a set of Samsung 30Q's, Charged to 100% at 8am Monday morning, Run at 40w in TC mode - batteries stand at 24% as of 1830 on Friday - so pretty much 5 days use from it...
What are people's thoughts on the sx200 version that is about to be released. Would anyone consider buying?
