Those e-cig sticks...
DO NOT HORK DOWN ON THE ATOMIZER WHEN YOU SCREW IT IN!!!
Only gently snug it down
Apparently there is a design flaw...the center connector has a rubber grommet under it to keep it from shorting, if you hork down on the atomizer or charger it crushes that grommet and shorts out the battery!!!
Aka...the toothpick fix (found it for you)

You can unshort it by getting something preferably non metallic (a toothpick) and gently prying that center electrode back and forth to "pop" it back up!
I killed two Totally Wicked Titan Tank batteries doing the EXACT same thing you did!
If you killed yours, you can get a replacement with a manual push button
