Hello, I am still new to vaping and need help. I recently lost my Smok alien 220 mod at work, I then purchased a DNA250/167 dual 18650 mod from a company called esauce in the UK. The alien mod ran in series so I new that the voltage doubled, I don't know if that matters with a regulated mod but I know that it never went over 20 amps from my battery. I emailed the company that built my DNA device and asked them if the mod ran in series or parallel and was told that it was neither, that it was a balanced charged mod, but that I could compare it to parallel. The batteries however, go in opposite directions like series would. I have not set the mod up for temp control since I have not learned yet how to do this so I have been running in power mode. I started with a baby beast tank with a .4ohm coil at 58 watts and the voltage goes to over 5 volts but the amps stay below 20. I then bought an ijoy limetless xl and with a .15 coil at 88 plus watts the voltage below 4.2 and the amps go above 20 and I don't know if that is safe. The coil is rated between 55 and 110 watts, it doesn't produce any vape unless at 80 or higher really. I am using samsung 25r and lg hg2 batteries. How do I tell if it is series or parallel or does that matter with a DNA device? Am I going to blow myself up if I vape higher that 20 amps? I would really appreciate some advice.
