Lowest I have seen yet!
It is the updated Vmax Variable Voltage Battery MOD V2, which output voltage can be adjusted from 3.0-6.0V volts in 0.1 volt increments. So Vmax can work on most cartomizers or atomizers with 510 threading from 1.25ohm to 3.0ohm. Vmax PCB allows 5 Amperage output limit.
The main feature of the Version 2 is that it can use the eGo style atomizers and cartomizers.
