As the day progresses I need more nic and more voltage. For three days in a row I've run down my eGo Twist 1000 mAh empty in barely 4 hours. Completely dead, the button blinks and will fire no more. I'm vaping with a Kanger T2 at about 3.8 v with a 1.8 ohm head. I wonder if the batt is defective or if I'm vaping too much. The numbers don't add up.
