I ordered a cloupor t5 from fasttech and a Sony vtc5 from eBay. I got the battery and my tank (kangertech subtank) before the mod So I tried out the tank with my buddy's 18650 mech mod and killed both of our batteries screwing with it. No problems. Both not fully charged.. When I got my mod in the mail, I plugged it in for about a half hour and tried to test it. it fired correctly once and then kind of sucked for the next couple. According to the battery life indicator on my mod it was draining about 5% each time it fired. Then the screen shut off and I plugged it back in. I waited about an hour and now it's like the battery is not even in it. The screen only works when plugged in and it does the exact same thing without the battery even in it. I have been anxiously waiting and tracking my mod for two weeks and now I can't even use it. Help! I hope its not the mod itself.
