Ok so I'm using a fairly new (2 week old) Kangertech T3S tank on a brand new Kangertech EVOD-C battery... When the tank is screwed on completely, the battery flashes and there is no connection. When i unscrew it about half a turn, it works. The battery is charged, the tank is mostly full, everything else is screwed on tightly.. I can't figure it out. I assumed it was a tank problem but my tank works perfectly on my boyfriend's Itazte battery. And his identical tank works perfectly on my battery. It seems to be the combination of my tank and my battery Please help.. thank you
