Well, I have a siegeli 30w mini, 2-eleaf istick 50w, and and IVP mini 70w. I mainly run a variety of kanger sub tanks but also have a few RBA clones. I have built sevaral different coils for all my atys. I am wanting a new regulated mod that has temp control for using nickel wire but can also be used with kanthal or Gplat. I was looking at a IVP3 150W or a Siegeli 100w plus or the SMY god 180 but none have temp control. I just saw a video on the Hcigar DNA 40 that seems legit.. However i want more battery life. I want a dual or triple battery mod. I work 12 hour shifts and want my mod to last my drive in, work, drive home, and chilling till i go to bed. My siegeli with a single 18650 2500mah does not last long enough, plus no temp control. My eleaf 50w's with the 4500mah built in batteries last long enough but still no temp control. I would also like to be able to build down to .1 ohm. Hopefully someone has some input or suggestion. I "will not" buy a mec/unregulated mod mainly because i change juices all the time. Many taste good at higher wattage while others need run at lower wattage. so i like the ability to change as needed Thanks for the input.
