but depends how much heat soak is needed? maybe 40% of the first battery going to heat them up or even less?It runs pretty low wattage on the mod so battery life should be decent though it will depend how constant you are cruising? And yes the standard configuration is plugged into the wall with VVPS, the mod adapter connector parts actually do cost extra btw
once it's heated I guess 3 sessions or even 4?
I'd use the 12V 5A VVPS or ATM with this beast... looks like a killer 4v~ log
