Baby steps. Your post screams first time builder plus you joined vaping underground for the soul purpose to ask this question which says the guy at the vape shop or a guy you saw blew a gigantic cloud and now you want to as well.
The problem is you don't know what you are doing and will make a pipe bomb. Learn battery safety, learn ohms law, buy a multimeter, find out what the better batteries are, and start by building simple .8-1.5 ohm coils and then progress.
The better battery brands are LG, Samsung, and Sony I believe. Stick with those but you need to find out what types of those brands to use. Some aren't great for low ohm builds.
