Hi guys, I've been vaping on Aspire zelos mod (50w regulated with integrated battery + siren v2 + Druga RDA) until now. My zelos mod stopped working after year of using it and now i need new mod. I would like to get mod which has 100 w capability and i found Vaporesso Armour Pro. BUT... it needs external battery and i don't have a clue about using those kind of mods and i would really like that one or 200w vaporesso revenger/revenger x so i could use my RDA for sub ohming ( couldn't use it so much on my zelos becuse vaping on 45 W would suck my battery in 30 mins). I'm lowkey ....ting my pants because i'm afraid of it burning my face or leg lol so i need your help... i tried to look it up on net but i can't orient myself cause there is toooo much info... So guys my questions are: What kind of batteries do i need? How to calculate parameters which are importnant? Amps etc.? I guess lol? What are your suggestions? I plan on using rda and rta so what should i keep my eye on? Thank you in advance!
