I bought some Volcano carts since they are supposed to fit on the blu batts. After I screwed it on and took a drag off of it, the blu batt started blinking and now is damaged!! When I put a Blu carto on it, it automatically lights up on it's own and won't shut off unless you unscrew the battery?? Even while unscrewed, the light will not shut off until you place it in the charger pack. WTF happened???
