Hello, I have a P22 vape pen with .3 ohm coil with a 3.7 volt battery which should be 58 watts. All the sub ohm charts show it to be in the red danger zone being too hot. Being a fixed voltage battery and sub ohm coil, do I have a problem of over heating the coil and producing formaldehyde from the vg in the vape juice? I use cbd vape oil that has vg in it. I do not care about how much smoke it produces I just want the benefits of the CBD. Is 58 watts too high, being a .3 dual coil is the total ohms .15 ohms or .3 ohms. Thank you.
