My history:
Started off 4 years ago with my Ego and actually always sticked to the commercial line of ecigs. green smoke > 10 ego's > Eroll > Egrip > Evic supreme with Delta.
Why? Because in my country/city there isn't anyone who is an expert, a shop that will explain stuff and the only stuff available in stores are Joyetech and other major commercial companies. If you go to a local vape store here and mention you want to buy a clearomizer they will say "a what?" and you just have to point it out.
So heres the problem: I always have the feeling im not having a good vape experience as the juice leaks, the vape isn't good flavored, to little clouds. And i want to step up to the next level (i always saw an evic as a line between normal personal vapors and boxmods/mechs). So i wanted to buy a boxmod and i got one last week as a present. The Vaporshark rDNA40.
But i got NO clue what to do with it. I checked countless of youtube video's, hell im even an ex physics student. And still i cannot safely say whats wrong or with regarding building your own coils (resistance wise).
Everyone keeps speaking off batteries being able to blow up when you don't do it correct. And this makes me worry, if i went RDA mode on my vaporshark and made a coil and i test it on a resistance meter and it shows 0.8 ohms will it be 100000% safe?
So basically my questions, if you guys can be so awesome to answer them are:
1) If the maths are right, and my coil is tested at a resistance meter to be proven above 0.5 ohms (using Sony VTC5) will it be safe? always? So 0.6, 0.9, 1.2, 1.4 etc?
2) How long does a self build coil last? How do i know to change?
3) is there a battery that regardless of mistakes is so strong that it cannot explode under any circumstances vaping related?
4) Why single, dual, or triple/quad coil build?
5) And last, is building your own coils really that dangerous if you go below 1.0 ohm to lets say 0.5 ohm on a Sony VTC5 or LG 2500mah 35A 18650 battery? Lets say i completely mess up my coil and make it 0.1 ohm, what would happen if i fire it up?
Thanks in advance guys, i really want to step up with my vaping experience, but the you tubers just make it seem al to easy while i keep reading about huge risks everywhere else. Hopefully i can get some more insight here!
