I have a question about my Smok Alien (220w). I'm not sure what my limits are on vaping and what would be the maximum wattage I can vape at safely. I have a 0.15 coil with 2 2500 mah 35a (3.7v) "Sigelei" batteries. What would be the maximum wattage I can vape at and be safe?

Stay under 150 watts and you will be ok...assuming the batteries are a true 20 amps each..they arent 35 amps as advertised..thats a maximum rating for a very short tenth of a second or two. Figure 75 watts per battery used [20amps] and this is taking them to the limit per cell...so, if you want some safety headroom stay under 150 watts.

Ok thank you so much. So 2 20amp batteries equals 40 so as long as I'm below 40 amps I should be good right?

Look for true 30 amp batteries...they will be lower in MAH rating so they wont last as long before needing a charge but will support over 150 watts in a regulated device such as your Alien. LG makes true 30 amp batteries...you can find them here or look for them at your favorite place. ...i would buy a few sets as they wont last very long at 150watts plus with 1500mah..https://liionwholesale.com/collecti...at-top-wholesale-discount?variant=13978272644
