So I had bought a coil recently and decided to use it this morning and went to use the mod and my Volts decided to shoot up to 5.7 and gave me a warning while I had a new coil inside the tank(baby beast). My mod told me to be advised to warning as i turned off the mod and checked if the batteries were fine and or heated due to the high vlts. But everything went back to normal So my question is do I need to get new batteries and or get a new alien. I did upgrade the firmware. I also took the tank off after that and threaded the tank back on and turned on the mod and everything was fine hitting right and everything.
