Hello, i have purchased a single V4L XL auto battery and another Ultimate kit of Medium batteries, the medium batteries worked great, and i am loving them, but i have a problem with the XL battery, when i tried to use it and after screwing the cartomizer i could not get any vapor, when i drag on the tip, i dont hear that popping sound i usually hear when dragging on the medium batteries,its like the cartomizer isnt heating up,so nothing comes out of it and i also hear a strange sound of air flow through the battery,just air flow, i also noticed that the cartomizer takes less time to screw to the XL battery than to the medium batteries, its like with the medium batteries i need to rotate the cartomizer alot more to get a tight screw to the battery, i am guessing that the cartomizer isnt screwing tightly to the XL battery,i tried different cartomizers but none of them worked with the XL battery, however when i take a drag the LED light on the XL battery flashes, am i doing something wrong or could it be that the battery is not working properly, anybody had the same issue ? i couldnt call the V4L customer service because it is a weekend, so i thought i could ask you guys for some advice before i call them on Monday.
thank you
