Yes I am an rda user. I like coil building usually get anything less than 0.5 ohms. So my Sony VTC that I've been using is getting kinda old and my backup battery that I've never tried for sub-ohming is this one: http://www.efestpower.com/images/up_images/20140506013442234.jpg
I dont really trust it....Do you think I'll be safe with it with my coil builds? Thanks

i know a few people using those 20A efests for sub ohms and several sites sell them for sub ohms i would be more comfortable using there 35a ones myself, the ones you linked to are listed as being able to go down to 0.4. Batteries and Safe Ohm Limits | DownEast Vapes
The 20 amp on the side is the pulse, and IMO that is not what you want to go by.
I have the 35A rates Efest battery that I use in my reo and it works just fine never gets hot and I never vape below .3 ohms....
The 35 amp batteries is a 35 amp pulse, IIRC they are a 20 amp continuous. While that would be acceptable for you since you don't build below .3Ω, but may not be what some need who go super subohm.

and btw if I'm in Switzerland what is the best site to buy VTCs from as they dont have them in stores.
akkuteile.de and eu.nkon.nl are good, though I'm not sure if they have them in stock. The Samsung 25r and LG he2 and he4 are good, but don't have as high a cdr as the Sony vtc. The "35" amp Efest (actually 20 amps) is a rewrapped LG he2 so it's good, but you can usually get LGs cheaper. The 3100 mAh Efest is a poor choice for most applications. It's actual cdr is somewhere between 4 and 6 amps, and it's voltage sag is considerable.

Is the bold really true? I mean i just investigated this and i really doubt that claim. Mostly because only 1 dude showed results of it and suddenly the whole web is saying it only produces 4a continuesly. Don't want to be a ...., but can you say the bold part with full convidence? I say this because i own the purple efest for a couple of months now, have vaped at it with 0.5 ohm builds (maybe even lower ,not sure now) and never had a problem with them. They last A LOT longer the the VTC4. At the moment i use the purple efest on my DNA mod with 15 wattage (so its modest) but i have read people going down to 0.2 without a problem and i havent read a single person saying it vented on them. Infact, this site actually says something else. Now whom do i trust? Myself and many others that are positive about this battery (including the site i showed) or that one german site and the people hopping on its bandwagon claiming what might be false conceptions?

Anyways to be on topic, i own the VTC4 (2 of them) and they never failed. Then again, i never went below 0.3 ohm BUT i believe the Sony VTC4 (or 5) are great batteries and prob the best for sub ohming. I believe the VCT are one of the few batteries with a 30a continues discharge (so its better then the Samsung and LG one). Still if you don't go below 0.2 ohm ish, the samsung 25r should be good too. this topic might be interesting for you (or tl:dr get the VTC5).

The 3100 mah efest battery is a good battery for vw/ww mod but i don't advice going sub ohm with it because of all the scare mongering going on (though i never had any problems with the battery).

Also Nkon is a great site (though they did slipped up twice with my orders, they always reimbursed/ send the correct products so service is great).

edit: sorry dudes and dude-ins, its late and i did not see the post date =/ guess i am a few weeks late lol.

I don't have any testing equipment nor would I be competent to do tests if I had the equipment. I just have to trust those who do tests, and dampfakkus is very reliable. Lytge-info are good as well, and as you can see in their tests that you linked, even if they estimate the battery as having a higher cdr than dampfakkus' estimate it's still well below 20 amps (10 amps, so half of the stated rating). Such tests can only provide estimates based on how the batteries perform, but with experience those estimates tend to be quite spot on.

Exceeding battery cdr doesn't mean that the battery will automatically and necessarily vent. You may be able to get away with it, but the risk that something bad happens increases exponentially when exceeding the capability of the battery. There's a reason why manufacturers give constant discharge ratings. To each their own, but for me it's just not worth taking the risk when good batteries with reliable ratings can be had for fairly cheap.
