What is short circuit?
Situation when battery positive (+) and negative (-) connect. The current will become extremely high because there is no resistance in the path to limit current flow. Short circuit will result in dangerously high temperature which may cause fire.
The use of any unprotected li-ion cylindrical 18650 battery as a stand-alone device, including with e-cigarettes, vaporizer pens or other products, constitutes a DANGEROUS misuse of the battery cells that poses a SERIOUS RISK of personal injury or property damage. These cells are only for prototyping with proper electronic protection circuits, and not for stand-alone use.
These are high discharge current & high capacity 18650 Li-ion batteries. If mishandled or mistreated, these batteries can cause you SERIOUS INJURY. USE AT YOUR OWN RISK.
