What's the difference between LR and SR? How do dual coils work? Are they ok for bottom feeding?
I need a buy this to get your RS temp. Vape lol
When it comes to the Oms stuff I need to be hand-held lol
LR (low resistance) is generally 2.0 ohms and below. SR (standard resistance) is generally thought of as 2.5 ohms to 3.0 ohms. -- And, yeah, that five tenths of an ohm in between is unaccounted for. It has only been about the last ten months or a year that 2.2 and 2.4 ohms stuff has been available, so that borderline stuff could be thought of either way, I guess. -- The other annotation used on the forums is HV (high voltage) which is 3.2 ohms and above.
HV SR and LR are never going to be exactly the same even if you get a close match on wattage output. -- I'll give you a suggestion for your 3.7v device, and I do think you'll find it satisfying. The 1.7 ohm smoke tech single coil cartos produce a nice warm vape at 3.7v. The perform really well. And you can buy them right where you are already getting your supplies. The other thing I think you should consider for your bottom feeder is the
1.8 ohm 306 atty. The 306 produces warmer vapor than its 510 counterpart and it does thread to your rough stack properly and will thread to any 510 connector, so you could pick up an 18650 3.7v battery for your maxi rough stack and be able to drip that same 306 as well as use it on a bottom feeder with a 510 connection.
I prefer Ciscos attys (
including 306s) for a couple of reasons. I've had a little better luck where durability is concerned, and they come without primer so there is no need to clean out any primer before use. But the one I linked to above has been pretty good for me too. I have one on my short rough stack right now, in fact. The reviews indicate some DOAs but I haven't had that sort of problem.
Just to recap that: For cartos, you will find very good performance and a warm vape from the 1.7 ohm smoke tech single coil cartos. You will get a *very warm* vape from a 306 LR atty.
Dual coils are different. There are two high ohm coils wired in parallel so the total resistance is half what the resistance of just one fo the coils would be. You said you have no electronics experience, so I'm sort of at a loss as to how to explain that to you. You'll just have to take my word for it, I suppose
--- Just an example of one device is the 1.6 ohm dual coil carto. It contains two 3.2 ohm coils. Because of the way the circuit is wired, the total resistance is half. So, two 3.2 ohm coils create 1.6 ohms of total resistance.
I personally believe that dual coils are best used at higher voltage than a standard 3.7v device because of the way the coils behave individually. I find the 1.6 ohm dual coil to be perfect at 4.8 volts.
I hope that helps. My best suggestion for you is the LR 306 atty. That is going to create a vaping experience closest to what you are used to with your 3.2 ohm device on HV. It's still a little different and 306's can be a little messy, but a 1.8 or 1.7 ohm 306 is pretty great on a 3.7v device.
