I noticed the following behaviour which can easily be improved. You can set your mod to a wattage, that exceeds the 6V limit and the mod shows "ohms too high". This is correct but the mod should not let you set a wattage exceeding 6V in first place The wrong part here: If your battery is draining and falling to 3.7V for example, the mod shows ohms too high again because it can no longer deliver 6V! This should be weak battery, not ohms too high. On a 0.4 ohm coil I get the warning at 3.5V at 77W, with a 0.48 ohm coil at 74W, I get this warning at 3.7V. Ohms too high is just not correct, they are in the 6V range, the mod just can not deliver 6V anymore and should display "weak battery". Also I am wondering why other chps can deliver 6V down to 3.2V on my samsung 30Q (at least I think so) but not the DNA250? EDIT: I am talking about the dual cell config! So DNA167
