so I just got a new x2 battery because I fried my last one out from charging it incorrectly. I wanted to get a new x2 because these x2 batts seem at least "to me" to vape differently compared to my spinners...the x2 seems to give a more airy draw and seems at least "to me" to work much better on my carts for some reason. when I go to vape my carts with a spinner batt it seems that it has a much tighter draw and it's like i'm not getting a good draw. I'm not sure if this is my imagination or what? I'm wondering if anybody else has noticed this difference in the tightness of the draw between the x2 and the spinner batteries when vaping on a cart? and I have also tried adjusting the VV on my spinners when vaping a cart, it doesn't seem to help....they are just way too tight a draw on my spinners so I switch to the x2 and vaping is much better on carts. mostly i vape the T3 minis with a spinner and that seems to vape gggreat...
