That's correct. On a freshly charged battery, it will put 4.2 volts to your coil until battery voltage drops, regardless of what the display says (The display shows calculated voltage for the resistance/wattage setting).Aye ok but is it putting oit 3.8 on a fresh battery? That is what I'm wondering because since there is no stepdown the mod will give out 4.2 on a freshly charged battery? I'm comfused by that. Thanks.
