Hi everyone, so i just got my v2 board from madvapes and wired it up and it seems that it's working but when i turn the dial my voltage is staying at 3.7 volts?? Do you have to use 2 batteries to crank up your voltage, also, i can't dial the voltage down either? anyone know why this is?(im presently using an 18650 battery to test it on a breadboard.
