By the way, I just placed an order for the Noisy Cricket & the Indestructible RDA. I was hopping someone could clarify something for me... Which is better, a series box mod or a parallel box mod. From what I understand, a series box doubles voltage & a parallel doubles the mah ?? I thought any mechanical mod could take lower resistances depending on how good your batteries are, but I just read that when building for a series mod you can't go below .25 ohms, is this true ? And if so which is best for super low ohms, like .20 ohms or lower series or parallel box mods ? I only ask bcuz I've always loved mechanical mods & I realized since VW/VV box mods have been so affordable & the Bees Knees as of late, I haven't purchased a mech mod in nearly a year & since my sweet spot has been .15 & even lower sometimes, I want to get back into my mech & hybrid mods. I built a nice coil on my Derringer RDA & SMPL mod setup the other day and I couldn't remember how low I should build or how low I used to build back when I first got it. Safety is very important to me & I use mostly Samsung 25r & Sony VCT5 batteries for the most part. But unless I'm mistaken, I was vaping between 1 ohm & no lower than .5 ohms before Subtanks came out & my mech mods started collecting dust. Anyhoo, I decided that I wasn't going to buy anymore VW/VV boxmods anytime soon & I wanted to buy a few (dual battery)mechanical boxmods & few more (single battery) mech mods. I just wanted to refresh my memory on the best mods I should buy, for my new super sub ohm style of vaping.
