I've been vaping for about 5 months now and i was wondering which batteries were safe for mech mods. Currently I have efest 18650 batteries at 2000 mAH and efest 18350 at 800 mAH. I know that people use these as well in their mech mods, but I was wondering which batteries would be the safest and best built for their mech systems. I have heard a lot about AW IMR batteries as well wondered what was better about them?

Some swear by AW, and you can't go wrong with them. Me, I use Efest 18650 IMR 2000 and 2250 mah, no issues with them.

But if you can find the AW and don't mind paying a couple bucks more, I say go for it. I looked for AW 18650 last week, for some reason vendors were out of stock, maybe your luck will be better.

Depends on what you are wanting to do with the mechs? If you want to go silly sub ohm and push 60 watts, you need GREAT batteries that will put out high amps. If you are going to stay around 1 ohm and higher, the AW's are good. I have a few of the Eftest IMR's and they work for me fine, but don't last as long as the AW's.
RTDvapor is a great source for AW batteries and if he's out you can go to Lighthound and find them there.

I agree with the others recommending the AW IMR batteries. These are tested and hand picked by AW as the best of the best. They are THE battery recommended by the ECF battery guru's for all applications. (resourse: http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html)

If you you presently or plan to do sub-ohm coils on an RBA/RDA, you need special IMR batteries with a maximum current discharge rate of 15 - 20 amps. Only a few batteries have this specification.

You can find this information and more in my blog: Battery Basics for Mods: IMR or Protected?

What do you guys think about mnke batteries?

One of the top choices if doing sub-ohms (20 amp max. continuous discharge rate). Lacking in battery capacity (1500 mAh) if used for standard vaping when compared to others available. It depends upon what juice device you are going to use.

I was looking for somewhere between 0.7-0.9 ohms. would I need to use the mnke's for that?

You can figure for yourself the amperage the battery will be required to make by using this Ohm's Law Calculator.

Plug in the voltage (4.2 volts) and resistance (0.8 ohms) in the appropriate places and press calculate. The amperage (current) and wattage (power) figures will be calculated for you.

I've researched the following high quality batteries for their maximum continuous discharge rating (amps). Choose the batteries which best give you a wide leeway in this specification for the safest choice. You'll see once you get to 0.5 ohm or lower is when the higher amp batteries are absolutely necessary.

Keep in mind you will be pushing your batteries under harder than normal circumstances which will shorten their overall life expectancy. And, as they age they will not perform as well as new - their amp production may suffer as they age and they will not be as safe as when they were as new.

I'm not really an advocate of sub-ohms. My experience with my own coils is the resistance of a wick/coil combo can change up to 0.7 ohms just by nudging the wick when removing the top cap of the RBA. It happens no matter how careful you are. If you are running a sub-ohm coil and that happens, you could have a 0.7 coil become a 0.1 coil by simply brushing it while removing the cap. Wrapping that low gives you no safety margin for errors. Just my :2c:. In a perfect world you might get by with a 10 amp battery, but we don't live in a perfect world. I personally feel you should go with the higher amp batteries just for the wider safety margin for unexpected events liked I described.
