I am new to this forum but not new to vaping. I have been vaping for about a year and a half, and vaping exclusively since Feb of this year. My home is almost in the exact center of the USA (one of the fly over states)so there isn't a lot of local vapers here. Nearly all of the information I get is from the people and sites just like this one, so I will be very respectable to you all. I'm pretty quiet so I probably won't post a lot, I like to listen and learn as much as possible. At the moment I am learning everything I can about batteries and battery safety. I've had only built-in batteries until recently and have only been running single 18650's. I have a dual 18650 coming this week so I need to know how to use it safely. Hopefully I can get Mooch the Battery God to answer my main question. LOL. And I'm sure it's been asked and answered a billion times, I just kinda want him to answer to my post.
