I have been vaping for awhile now but am just now getting into dripping. I recently ordered a brass Monkee rda clone, an ohm tester, kanthal, a battery and some juice. At the moment I am using a Kamry k100 telescopic empire mech mod. It came with Kamry 18650 and 18350 batteries and today my rda came in which came prewicked and I believe the coil will be running .6 ohms. What is the main the risk of using my rda before my VTC5 gets here? I want to be smart about it before I just go for it. Appreciate any responses!

0.6 ohms will put you right at 7A draw on a freshly charged battery at 4.2VDC.
Even most of the crappy batteries are rated for 10A, so I'd say you're probably safe at that level. If you are concerned, rebuild your coils and keep it around 1ohm. You'd be in the green for sure at that point.

Now, to answer your other question, the risks of dripping relate directly to how low your resistance is and how high your battery is rated. Some suggested reading can be found in the link that is in my signature titled "Bad's Awesome Blog"... pay particular attention to the battery safety and ohm's law sections. Let me know if you have any further questions, and I'd be happy to help you out.

Depending on the battery, death is a definite possibility. Catastrophic battery failure could do anything from just scare you a bit to kill you and burn your house down.

Not knowing EXACTLY what you are doing can be fatal when you run sub-ohm builds on a mech.

You must KNOW FOR CERTAIN what the continuous discharge limit of your battery is. If there is ANY DOUBT, do not sub-ohm.

Hello and welcome to the forum Cory. Glad to have you here!:)

Your battery could vent or even explode (if your mod does not have sufficient vent holes) IF:

1. Your batteries are not IMR or IMR/hybrid, safe-chemistry, high-drain batteries;
2. You exceed the amps rating (continuous NOT pulse) of your battery;
3. You don't measure the build before you put it on your mod and fire it.

If you need links on any of this, please let us know.

Kaezziel, I want to point out that assuming a battery is rated for 10 amps is not always a good idea. I have some ICR batteries that are only rated for 4A, and these are the ones that "vent with flame/ explode" when beaten upon. Also to clarify the ratings a but, the lower the state of charge of the battery, the lower its constant current rating gets. It could start out at 10A freshly charged, but it might not actually be able to handle the load at 50% charge.

You're right, HMav... I should have explained better. If I remember correctly, the Kamry 18650 is a 2000mAh battery with a 10C rating. That places it in the 20A max discharge range. My earlier assumption was based on the fact that the battery was shipped with a mechanical mod, and therefore should be rated for at least 10A... the error in that assumption is that not all vendors agree, and some ship crappier batteries than others.
I should also have pointed out that the 18350 is likely an 800mAh battery and is probably rated for less than 8A... and therefore should not be used for sub-ohm vaping.

Thanks for keeping me honest! :)

Well, according to that spec sheet... that's a 2A limit battery... :unsure:
Doesn't exactly match what I saw once upon a time, but I sure wouldn't risk it... could be a typo on the spec sheet (1.0C instead of 10C), but better safe than sorry! Hold off till you get the better batteries... I recommend checking out rtdvapor.com and getting the Xtar 30A batteries... Sony isn't producing the VTCs anymore and the Xtar is the exact same battery... besides that, rtdvapor is a reputable vendor. Never trust eBay or Amazon for batteries...

Those batteries are ICR chemistry. Save them for your flashlights.

Here the are blogs that Kaezziel was talking about you may find beneficial: Baditudes Blogs. The blogs regarding battery safety, Ohm's Law, amp draw, etc. are listed below:

BATTERIES

9. Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

17. Purple Efest Batteries Not As Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

14. Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

16. Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

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

I wouldn't use those batteries at all, unknown cell of unknown quality & CDR.
I have found no semi believable spec sheet, what I did find for the 2000mah 18650 is a range from 1c (2a) to a high of 6a CDR.
The 18350's rated from 700 mah to 900mah and .5c to 5c ( .35a ~ 4.5a CDR)

I hate to be the bearer of bad news to someone new to vaping but, the chance of your yet to arrive vtc5 being real / authentic are very, very slim.
