I don't know what the very maximum the AeroTank
coils will handle.
But, I have been experimenting with my AeroTank mounted on a variable voltage battery. Seems like the sweet spot that gives good flavor and a good amount of vapor is
4.5v
The dual
coils on the AeroTank are rated at 2.0 ohms, however, power is being split between the two
coils:
.... 4.5V at 2 ohms is 10.12 watts
.... But, that is actually only 5.06 watts per coil
Hope this helps
