I am interested in trying out some diy mods. I thinking of getting a simple 510 box mod kit form madvapes for my first mod. I have a couple questions. If I understand right, the pos from battery goes to the switch then from switch to pos on atty. Then the neg goes to switch and then to neg on atty. Is that right? Then solder everything together and fire it up? Do I have to use the resistor for the led if so how do I hook that up? Do I even need the led? I don't really need it to light up just work is good enough.Can I dump silicone to hold everything in place? Also what kind of solder should I use? I know this is a simple mod for everyone else but I just want to understand how this thing works. A simple 3.7 is good for now 5v and VV well thats for next year or something. It be cool to just have a few different looking mods. Thanks.
