With 3 preset voltages to choose from, the new ECT COS battery is perfect for vaping thick oils.
This battery operates slightly different than other similar batteries. This battery has a 15 second pre-heat function that must be used in order to use battery regularly. So, you would push the button twice to start the preheating, and after 15 seconds you can fire the battery normally. After 10 minutes, the pre-heat function would have to be run again for use.
