[h=2]So, i bought a joyetech 18650 mod v1 from goodejuice.com and after 3 days, the control unit failed and got stuck on, wide open! burnt my fresh emdcc all to heck. anyway, i contacted them and they want me to ship it and my battery off for inspection and replacement. after paying shipping and what not, i might as well buy a whole new head. problem is all i can find is the v2 head and it says its not compatible with the v1 tube. i can hardly believe that after looking back and forth for a while and think it will fit. any one have any expierence in this or know y it is not compatible? is the battery polarity orientation the same? thanks![/h]
