I am planning an upcoming purchase, and would like some backup and insurance everything I'm looking at will be correct. I have primarily used VV devices to date, but am looking to get into a mech beyond the K100 and Magneto I used to cut my teeth on with in regards to mechanical mods. The plan is as follows: Tarsius 4Nine Mod Efest Purple 18350 700mAh 10.5A Batteries Sony US18650VTC5 2600mAh 30A Batteries Patriot RDA, micro dual coil build, cotton wicks (already own) Kayfun Lite+, micro coil build, cotton wicks (already own) My calculations show fully charged at 4.1 volts, with resistance sub-ohm at 0.5, it should produce 33.62 watts at 8.2 amps. This should place it within the limits of use for both batteries I have selected above. This would also be as low as I would go with the resistance. So, details all told, will these calculations remain true with a dual coil build? Essentially, I want to know if the 10.5 max amps of the Efest 18350 is ok to run a dual coil build with a final resistance reading of 0.5 ohms. Unless I am completely wrong, it I believe it will run the single coil 0.5 ohm build in the Kayfun, but didn't know for sure about the dual coil RDA build. Additionally, I would like input on this "shopping list" and if I'm looking in the right direction with everything I've selected. I love the idea of a mech mod in 18350 mode coming in under 2 inches and then topping it with a nano Kayfun Lite. Thank you in advance for the assistance.
