I got my new Nautilus mini. I usually vape at 4 volts. Anyway i was reading and read that the BVC coils vape better at higher volts or wattage. I read vaping at lower voltage while will work but will gunk up the coil. Anyway I switched over my device to watts for the first time ever and set it to 13 watts. But when I fire it says it is only pushing 11.1 watts. So I went back to voltage and set it at 5volts and and I fire it says only 4.8 volts.. Ok switch out the battery.. yup same problem. I have 5 batteries total and they all have the same problem.. they won't go above either 4.8 volts or 11.1 watts. I use AW IMR batteries and charger that stops charging when complete. So whats going on here is my V5 broken or are my batteries going bad..
