Got an X6 battery from my freedom smokes a few weeks back,love the battery, great design comfortable to hold, fits in pocket nicely, produces good vapor when paired with a decent clearo and great battery life. Only have one issue with it, when I use my kanger t3s with the battery it has a tight draw, one of the things I like about my t3s is the airy draw I get on a standard ego battery. The collar at the threads on the battery seems to be the problem it's not giving me enough airflow. Anyone know if I could safely drill a few small holes in the collar without damaging the battery? I figure a few holes would open the flow back up and let air get into the t3s easier. Is this do-able?
