been stacking 18350 batterys for years== 6 volts. i want to stop!. looking for the hottest, most amp, most watt -- battery on the market. to put in my mech. mod.
I also want to match it up with a no less than .7 ohm coil. looking for a starting point.
I agree with what others are saying. Let me try to explain in laymans terms....
Let's say you're vaping a .7 ohm coil with two 18350's.. Lithium batteries output 4.2 volts on a fresh charge. If you stack them, you should be putting out double the power. Not counting the voltage drop from your mech mod, Go to
Ohms Law Calculator and plug in the two variables you know and see what kind of power you're putting into that coil.
That, is a cloudchasing build. It's funny you mention that, because I run a .7 ohm coil in my Sigeli 100W. However, I run mine at 25 watts. I use two 18650's.
If you're getting 6 volts out of two 18350's, then you have either a defective battery, or a severe voltage drop in your mech mod... clean the mod and contacts to improve it.
If you want to go with a single 18650 build, you'll have to experiment a bit to find a vape that works for you. There are MANY factors that go into a mech mod build. First start with the battery and voltage drop. Find out what voltage you have to work with. Assuming you have a good setup, let's say you have 4.1 volts on a fresh charge. Next, you select the wire gauge.. this has just as much to do with your build as your ohm rating. Higher gauge wires are thinner, heat up faster, cool down faster, but offer a higher resistance, so the coils will be smaller for the same ohm build. if you did a .7 ohm build using 32 gauge, the coil will be way too small, but heat up almost instantly. IF you used 22 gauge, the wire would be thick, and it'd be way too long to fit effectively in a dripper, it would take a few seconds to warm up, and would take a few seconds to cool down after you release the button. So, unless you hold the button down for a long time, it would produce less vapor. So, find your happy medium.
Is there any particular reason why .7 ohms is your limit? IF you have even a "medium" high drain battery rated at 20 amp limit, you could safely do a .3 ohm build. What I'd do, is find a good battery, and know it's amp limit. I personally don't build above HALF that amp rating... I like to vape safe. So, I have a Sony VTC4 with a 30 amp limit.. I plug in the numbers into the ohms law calculator and come up with a .28 limit.. so, I don't build below that. I usually vape at .4 ohms on a mech mod. I find that 26 gauge works perfect for me... I tried 24 gauge, but it took too long to heat up for my preference, and 28 gauge was just a bit too short for my builds, so 26 gauge fit the bill.
So, just experiment a bit. The other option is to go regulated.. my All Day Vape has become a Sigeli 100w. Of course, I never use the full 100W, but if I wanted to, I could pop my Mutation X on, up the wattage, cloudchase for a few minutes, pop my tank back on, lower the wattage, and go back to my tank. With the higher wattage devices coming out, there's no reason for me to cloudchase on a mech mod anymore.
Anyways, just my opinion.
