Didn't find anything too wrong with ET's reply... @anton is playing with a potentially very dangerous combo and almost just joking about it constantly.
Not to say that @anton should not return, but he claims to be old enough - Thus I am sure he can deal with some warnings...
Of the 3000 confirmed chemicals within them, It is probable that to some extent it does and at the very least a combination of chemicals that form alcohol! :D
As much as one cannot say the type of wire holds little information ("Tiger coils"), the resistance outcome is far more valuable. Vaping at 50-55Watts is probably a .3 / .4 ohm build I would say... You could try building lower at .2 ohms etc, which would allow you to "up your wattage" and...
I'd say most subohm tanks are great for high wattage everyday :) 60 - 100W you cant go wrong with a Billow V2 (havent tried v3), Griffin 22 & 25, Gemini/Gemini Mega, Limitless RDTA, Doge RDA/TM RDA's.
100W is high wattage for me! 60 - 100 is where I sit, unless its a single build and ill vape...
If you compare both boards next to one another, is there any visible damage, like a burnt spot on the PCB etc?
Are they both RX200? not 200S or DNA200 right.
You sure this wasn't perhaps causing the overheating issue previously. 7.4v out of your 3 batteries indicates an issue, and this would mean the mod wouldnt turn on I suppose... Have you tried other batteries?
*Didn't see @Feliks Karp reply above, thought the same.
Different strokes for different folks... You will never know until you try, well - you will forever believe what you have read until you try it for yourself :)
Super confused, just to understand - the mod with batteries, does not turn on - but it does if you plug in a USB cable? What happens with other batteries?
