Can someone that has an omnitester and eleaf istick please put a 2.1 ohm coil on it and find out what the setting for 4.3 volts under load for me please? I want to set it for 4.3 voltage output, and since it runs hot, you cant just set it for 4.3. and because this mod uses PWM, I am unable to do so as my tester wont do this and I do not have an omnitester. PLEASE HELP!!!
