Hey guys, just joined the forum. Ive been vaping for a while but haven't gotten into RBA/RDA's yet, Ive known how to build them for a while as I have built them for friends, just never owned one. I recently ordered a few RBA's and RDA's. I know that sub ohming can be dangerous if the battery you are using can't handle it. I was wondering what the best batteries are, Ill be building coils anywhere from .3-.7 ohms. I can buy multiple batteries, so whats the safest? Figured it would be a good idea to ask some people who know about these things instead of just buying a battery and having it blow up in my face or something. If it helps, I will be using a JD tech scorpion, very similar to the nemesis. The RBAs and RDAs I have are the AC9, RSST, Trident, and Nimbus. Thanks!Happy vaping!
