I just started vaping on it. I love it thus far, but I'm only about 15 min. in. I was just wondering if anyone has any tips, or tricks for maintenance, or to improve performance. I got the 1100 mah batteries. I'm guessing they came partially charged because the first one was only on the charger about an hour before the light went green. Thanks in advance. I started vaping about a month ago and am really enjoying it and the forum.
