So is it the lower the ohms the lower the resistance or vice versa?

It really is hit or miss. Some eGos seem to be able to handle 1.5ohm and 1.7ohm cartos with no problems, and others will fry with a 1.5ohm or 1.7ohm. I think the slight variance in production has something to do with that.
I have 2 friends that both bought eGo kits from the same vendor at the same time. One uses 1.5ohm DCs and has never had a problem. The other one just fried his eGo last weekend using a 1.7ohm Ressurector (which should actually stress the eGo mosfet less than a 1.5ohm). So thats why I dont recommend using anything below 2.0ohm, more or less just to be safe.
And personally I think dual coils are really nothing great on an eGo. Even on my 3.7V E-Power their just okay. They are alittle better on a 3.7V compared to an eGo, but their still nothing special. I find DCs really only shine in the 4-5V range.
Personally I think a good single coil carto is just as good as a DC on a 3.7V PV or 3.3-3.4V eGo. I have a few of the E-Power Dual Coils that are 1.5ohm and hold 5ml of juice and while I do like them, the Ressurectors produce just as much vapor and dont drain the battery like a DC does bc their single coil. Plus their much cheaper than DCs are

I've used 2.0 ohm attys and cartos for a considerable length of time with no issues. 2.0 ohm Boges (or any other carto) provide good vapor and taste, similar to what you get with a dripper atty. The 1.5 and 1.7 ohm cartos will put more load on the MOSFET in the battery, but lots of people do that and get by just fine.

If you want to calculate wattage from a particular resistance, use the formula P= V^2/R, where P = Power in watts, V=Voltage, and R = Resistance.

EX. 3.4 x 3.4 / 1.5 = 7.7 watts

A 2.0 carto would draw 5.0 watts and a 3 ohm carto would draw 3.85 watts. You can see how much more current is drawn at 1.5 vs 2 and 3 ohm cartos.

you must be talking about the CCV ones then. every DC (smoktech ones) i've gotten has been at about the $1/unit price, sales help of course, but i'm not sure why theirs are $2+ each.

perhaps the 1.7 single coils are just as good in vapor/flavor, but the DC's should outlast them, plus i haven't seen any SC's cheaper than DC's myself, not sure why that is even. you would think they'd be simpler to make, less materials/etc...

Wow glad i read this post. I have an ego T and ordered a bunch of LR attys and cartos. I didn't know they could break the battery. also ordered some dual coils. Wish I read this before I placed my order. Was going to get a DCT from smoktech. would that not be a good choice for an ego batt? Also ordered a KGO which I heard was better closer to an actual 3.7 Would the dual coil tanks be better on that? I'm also using 1.5 ohm cartos at the moment. So far so good but now I'm a little worried.

Lie I said, you could use them and never have a problem. Bt theres also that chance that they could fry the mosfet.

The Smoktech tank comes with a 1.5ohm Dual Coil, which could potentially fry your mosfet, but only potentially. Your using 1.5ohm cartos now and its okay right now, but still be careful bc that doeant mean that same carto wont fry it a week from now. If your going to keep using them I recommend getting a multimeter so you can check them. Cartos can slightly drop in ohms from use and that slight drop could be enough to push it over the edge and fry it. Also all cartos arnt always their stated ohms. Most can be +/- .2ohms. So if one is actually 1.3ohms or drops to around there from use, they you really risk it frying your mosfet. Thats why I recommend 2.0ohms bc then if it does drop, the slight drop is less likely to kill your PV.
Using a multimeter will allow you to check the ohms to see what the carto is actually at, and then you might be able to catch a carto that isnt the stated ohm or drops in ohms from use, which could have potentially fried your eGo.

I think youll like your kGo alot more than the eGo. The kGo is a 3.7V device instead of the 3.3-3.4V eGo. 3.7V PVs handle the lower ohms better and you should have no problems running 1.5 and 1.7ohm attys/cartos on the kGo. The kGo actually comes off the charger at 4.2V then drops to 3.7V after using it for alittle. The batteries last a long time too which is always a plus and most kGo users get a full day from one battery.
The kGo will work great with the Smoktech tank. I also recommend trying the Ressurector cartos on your kGo. I use an E-Power which is similar to the kGo but uses non-proprietary batteries, and the Ressurectors are the only cartos I use.
I have one of the Smoktech tanks too and it works well. Personally I only like dual coils in the 4-5V range, but you might like them. If you want to use something else nesides the dual coil that comes with the tank, CCV now sells pre-punched Ressurector cartos that have the metal base to be used in the Smoktech tanks. I like the Ressurectors in the tank alot more than the DC that comes with it.

The lower ohm resistors don't always kill a battery out right. But sometimes they do. You've been using the 1.5's and no immediate death to a battery.

But, and there's always a but. It will certainly shorten the life of the battery. There will definitely be less time between charges to the battery, given the same amount of vaping. There's also another side effect of less recharges over the life of the battery. Say the 'typical' battery is good for 300 charges. By using lower resistance cartos you'll not get that number but less, maybe 250-275 recharges. It also depends on how long you hold the button down when vaping but that effects the mosfet more then the actual battery.

There's some really good explanation here somewhere. I think I saw them in the battery mod section describing these phenomenon.

It's more about the amperage (current) then anything. Since heat ,loss is current squared times resistance. And it's these heat loads that mess up everything. But since the voltage is constant a lower resistance means higher current.

Many of these batteries are supposed to be protected but that doesn't mean more heat and lower resistance is good for the equipment.
