I have a smok variable voltage battery, it goes from 3.2 to 4.8. And I have a kangertech evod atomizer (single coil). Can I use these together? And what is the reccomended power to use? coils seem to last about 2 to 3 days at 4.8, but a week at 3.2, although 3.2 is no fun also I am new to this whole ohms thing and what ohms coil should I use? Thanks
