Gonna vote a strong "no" on whatever it is you're about to do until you do some more research.
First off, using dual coils halves the resistance. .37/2 = .18 ohms. This exceeds the amp limit of any 20A battery on the market. So right off the bat, no, that is not safe. Add to that, there's gonna be variations in the coil resistances because they're pre-built in a factory, likely with little to no quality control. If you have no way of measuring the coils before attaching them to your atomizer that's a problem in itself. Never attach coils with unknown resistances to an atomizer.
Secondly, the SMPL is a faux hybrid mod. The atomizer makes direct connection to the battery. This is a big "hazard zone" as it makes the possibility for a short
way higher. Add to that, the SMPL has been proven to have inadequate venting capabilities, as it's essentially just a solid tube. I don't recommend the SMPL even to seasoned mech veterans.
Basically, everything about your setup is asking for trouble, and it's only exacerbated by your lack of knowledge.
Start here, and do some serious reading.
