What resistance are you generally running and how long is the battery lasting for you?
I usually run about 1.5 ohms (that's my sweet spot in about everything I vape). The battery will last me most of the day if I'm vaping on more than one device (and I vape quite a bit, not quite chain vaping but close). But if I just use the VS maybe 4 or 5 hours. That's with it set to about 10 to 11 watts.
