Does anyone have any suggestions as to how I can get my Bannana carts from NHaler to work on my manual and PT (sealed) batts. I have a VK 808 and I notice the Bannana cart is not notched like the V4L carts. I ordered an XL 808 batt from Drew and it is the same design as VK so the bannana carts still do not work. I also got a five pack of blanks from Drew and they are notched. Please help me so I do not let all of that bannana goodness go to waste. P.S. The carts do work on auto batts as they are not sealed so the air can flow.
