Hey guys, new defender user here, as well as first time e cig user. Have a few questions if you guys dont mind. When i got the defender in the mail i charged it up until the battery was full per the website instructions. Now i was wondering what the majority of you guys do from here. Do you let the battery drain all the way down before recharging? do you always fully charge regardless of level? Also is it going to effect the battery one way or another if i chose either method? last question, how do i know when the battery is low? is their any indicator or will it just shut off? does the vapor/taste get weak with a lower battery? If you guys could point me in the right direction i would appreciate it. Thanks in advance.
