Okay so i have my RX300 mod with a tf48 tank and quad coil it has worked perfectly but one day I charged my E fest batteries and when I go to take a hit the mod hits at 12.1 watts for 2.4 sec give or take and then hits and the wattage I have set like 130. The coil is rated for 120-180 so 130 is and never was an issue I just don’t understand it please help I have the version 5.04 on the mod
