When the battery level drops below 3.0V, the device will not function, and the screen will display “Low Battery” for 5 seconds to remind you to charge it.
When connecting the mod to the charger, the screen will display a growing battery icon. Once the battery level reaches 4.2V or when it’s fully charged, the mod will stop charging and the screen will shut off.
Capacity of standard version is 4.2ml , TPD version is 2ml .
