Here are Two pics of a hybrid mod top cap I recently bought. As you can see, the positive tab on the battery is directly connected to your 510 pin or whatever it comes in contact with at the bottom of your atty.
Here is a pic of the 510 pin on the bottom of the Atlantis:
The pin simply pushes into a grommet and floats there. If the pin comes in contact with the side of the atty it will short the circuit and if left there will short the battery. Notice how close the pin is to the sides of the atty. If that grommet gets deformed in any way, that pin can touch those sidewalls and short the circuit. After screwing and unscrewing the atty on and off mods, that pin and grommet can move out of its centered position. On a hybrid mod if this atty is over tightened directly onto the positive tab of the battery, the pin can MASH down onto it, deform the grommet and touch the sidewall causing a short. Someone not aware of this with little experience has a ticking time bomb in their hands. Be safe out there.
