Theres still Kangertech gear around? I thought they were completely dead, so theres a ringing endorsement. then theres them releasing some of the worst and unsafe products of all time..Neebox anyone?
Moving on....
Your title asks about mods, but then you references tanks as well
If youre looking for a 5ml+ tank, youre limited to a very few, and if you're expecting to find one with factory coils, then theres probably an even smaller amount of choices of tank....i haven't bought a new tank (until last week) in over 2 years, so im not up with what available
Fasttech lets you search Atomisers via liquid volume in its left hand column:

As for mods
Out of those i would choose one of the GeekVape Aegis mods depending on size and runtime or watts needed
Then theres the more complex answer to single or dual batteries...and theres part a and part b of that...
Part A: Do you want a dual battery mod for battery runtime?
Im not a huge fan of dual battery mods, it adds a slight complexity in the area of battery recharging...you *should* (read: definitely need to) buy 2 batteries and marry them (i.e. mark them each as a pair B1 & B2 etc) and always charge them as a pair, and always in an external charger. A single battery mod, feel free to internally charge. I also vape at no more than about 37w ever in temp control mode
Then theres
Part B: Do you want a dual battery mod to vape at 75+ watts?
to the dual battery mod, do you want a dual battery mod because you want to vape at 75+ watts (safely)? No, then buy a single compact battery mod and swap batteries as needed. If you need 75+w (safely), then yes, dual battery mod, be prepared its going to be larger and heavier and you'll definitely need to factor in an external charger.
You prolly thought it was a simple question
