Quick question, my wife as a BB from altsmoke...the battery was getting really hot shrinking the plastic wrap on the batt and the spring shrunk so the batt could not make a connection. She was using a 306 atty when it happened. Never had an issue before. 14500 900mah ultrafire batt. I took the 306 and put it on an ego batt and my silver bullet and it is shot. I straighted out the spring, used a new carto and it is working again. WTF happened?
