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'm a little concerned about what you're asking. All 18650's are going to put out 4.2 volts fresh off the charger. So in that regard, for a given coil, there isn't a "hottest, most amp, most watt" battery. Since you're using a mech, it's your job to tune the resistance to get the vape that you want. At 0.7 ohms, you'd be getting 4.2*4.2/0.7 = 25.2 watts at first, then it'd trail lower as you vape (about 20 watts at a 3.7 volt charge, a good time to charge the battery).

And there are a few reputable suppliers out there. RTDvapor, Illumn, and Orbtronic come to mind (I know there's a 4th that Susan may come around and post :)). VTC5's and VTC4's are pretty hard to find, so I'd stick with something else. I landed on Samsung 25R's, but that's just me.

You rang?:) I was busy ordering a pizza!

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

There appears to be a few holes in your mech mod education. So we can help you fill them up. Pay particular attention to Ohm's Law. Once you understand this you will be able to answer your own question as to what battery you will need (as far as amps go) to support a 0.7 ohm build.

I highly recommend you spend some time with Baditude (our resident battery expert) and visit his blogs. You are 100% in control of your own safety (and others around you) with a mech mod. Make sure you purchase an ohm reader (if you don't already own one) and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:

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.

You're never going to draw more than 6 amps at a minimum 0.7 ohm build.

I wondered how Sony VTC4 2100 mAh, Samsung 25R 2500 mAh, Panasonic NCR18650PF 2900 mAh and Panasonic NCR18650B 3400 mAh but only 7A rated, would all compare.

Here's the chart at 5A. The Samsung 25R wins down to 3.2V under load, probably the lowest you'll ever want to go.
