Hi guys! Maybe this sounds crazy, but it is possible to modify firmware, so that, when in use with a dual (or tria) battery mod (like e.g. Wismec Predator), it uses only ONE battery and when its empty it switches to the second one? idea behind: I used Pico istick with one battery, its not enough for the whole day, so bought Predator. its much better, but ends also at 10 pm. I use it only with 40 Watt (0,5 ohm coils in Melo4) and it would be nice to use the batteries one after the other. I hope you know what I mean, sorry for ma bad english.
