Many of us vapers use both regular LR attys/cartos and the unique dual
coils on fat batt
batteries,
despite the warnings about mosfet. Proceed at your own risk ... realizing that the risk is to the longevity of your battery, not to life and limb; it's not going to blow up on you. I would not use that 1.25 ohm dual coil on a fat batt. That's pushing it, even by my devil-may-care standards.
[I defined 'mosfet' in
this post.]
Notice that I referred to the dual
coils as unique. Their resistance is not as simple as 1.6 ohms. For example, I prefer them at 3.7V (rather than the eGo's 3.2V, on which a 1.7 ohm single coil hits hard). But I don't think my 3.7V KGO likes them: one of my KGO batteries refuses to work with the dual coils.
All of these LR and dual coil cartos work best on 3.7V
mods (at least the ones that can handle 2+ amps current), some of which are no more expensive than an eGo or KGO. For example, my 14650 based NoEgo costs $25. It doesn't include battery or charger, but you can get those elsewhere, e.g., an
IMR 14650 for $9 and
TR-001 Multifunction Charger (for
all 3.7V batts) for $12 from ElectronicStix. Total cost: $46 (plus two shipping charges). MadVapes carries the
same charger for $10 and a
non-IMR 14650 battery for $6.50.
MadVapes (along with several other suppliers) also carries the virtually identical
e-Power as an all-inclusive kit for $46. [I already had the charger and I preferred the appearance of the NoEgo, so I went with that. Someone new to mods might prefer the e-Power.]
