I have an IPower they I had for a while. Just started using it occasionally now because my alien died. This mod can go up to 80 watts. Does that mean that because it's an internal battery that it can 100% safely use 80W? I know that with my smok AL85 that I need to watch out on my wattage and if it's a 20 Amp battery that I can safely go up to 60W. Are there any procautions that I need to make or take as far as how high wattage I use in this IPower? I'm just trying to be safe. Thank you.
