Hey guys I just joined but celebrating my one year analog free anniversary. I have been into mech mods and rdas. My current is copper overdose by mcv and mutation x v2. I just bought a kayfun v4 to replace my 3.1. Loved the 3.1 but it was a pain to fill and rewick. The v4 however is great. Only problem is I was dumb and bought a dna 30 mod from my freedoms smokes which turned out to be a clone. This pi$$ed me off but I shoulda known better for $100. I am using the kayfun on that but want to go a little lower in resistance. Currently I have a 1.7ohm chimney build but want to go lower like maybe .5 - .8. Can anyone suggest a decent box mod preferably 18650 considering I have a bunch of batteries, that can handle it and maybe take it up higher than my mech mod would. Thanks in advance.
