so i just got my titan stealth manual XL battery in the mail. first thing i notice is that it seems that there is something loose inside. i can feel movement inside the battery casing. so far its functioning fine but i want to know if anyone else has experienced this before, and whether or not it may be a problem. if its a defect that affects my vaping i am going to try and get another one. btw this is my first XL battery.
