hi first of all i would like to say thank for having me here.
my problem: i have a coolfire 4 and all of a sudden its started just flashing 4.0v every time i press the fire button and stays doing that until i switch it off at the bottom none of the plus or minus buttons do anything.
ive charged the battery fully also removed tank no ohms show when tank is on any help would be greatly appreciated thank you.
