Is it just me, or do some tanks and batteries just not play well with each other? I have had issues with EVERY Kanger (Evod & Protank) I have ever tried. But so many people swear by them. On the other hand, I have had great success with the Aspire BDC line and I have seen several posts here calling them junk. I have 2 itaste vv and MVP2. It is also worth noting that the Evod tanks actually didn't have many problems on my starter eGo battery. It was after my initial upgrade (first vv) that they started acting up.
