Been looking around for my first mod and have it narrowed down to either a gg or super t. The problem seems to be the battery life. Looks like both of them only last about 2 hours on heavy vaping. I was really looking for something that would last all day. I don't really want to keep recharging or keep a lot of extra batteries with me. I currently have a Joye 510 and got a pcc but would like to lighten up my arsenal. I work 12 hour shifts in manufacturing and carrying all this stuff around is getting cumbersome. I am looking for a true 3.7 volt that isn't too big with sealed battery compartment and hopefully a locking switch so it doesn't turn on in my pocket and is 510 compatible. Any help will be most welcome.
