Bought my first Mech today!

Bought my first Mech and rebuildable today!

Got a sigelei K100 and a Phoenix v10 dripper, 18650 2000mAh battery. A good place to start I think.

Any newbie tips or things I should/shouldn't do? The clerk took 45 minutes walking me through the first dual coil build, like 1.5 ohms (A 5-6 wrap 32 gauge, store policy not to sub-ohm). I have some 28 gauge and some organic cotton. He recommended doing a 28 ga. 5-6 wrap on a 5/16ths bit to get it at like .5-.6 ohms. Any tips would be rad.

By the way. If you live in Columbus Ohio and you want some very helpful and knowledgable walkthroughs, talk to the people at AltSmoke on N High St. Luke could not have been more helpful and made sure I knew how to use my setup safely and effectively, especially concerning battery safety.

Just be triple sure your battery can handle the output of whatever coil you build, and you should be good to go!

As always, if it feels hot in the hand, or especially at the button, stop, find and fix the problem immediately!

Brand of batteries would help us provide advice. Most 2000mAh 18650 have around a 10amp discharge rate. Some are higher, like EH (16amp I believe). In that case, I wouldn't go below .65 ohms for a 10amp battery.

5 or 6 wraps of 28 gauge with that size of bit won't be .5 or .6 ohms. A 4/3 wrap gets me about .8 ohms so 5 or 6 will give you around 1 ohm. A dual coil with that many wraps will get you around .5 ohms.

That's the only text on the battery. I find it hard to believe that he would recommend a build and send me on my way without the supplies to do it. I'm in his store at least once a week.

Is AW the brand? I think it is referred to as a AW IMR 18650 2000mAh. At least it is on performance charts. http://www.e-cigarette-forum.com/forum/apv-discussion/302738-aw-18650-batteries-really-not-best.html

AW is a brand, but not a manufacturer - what they do is buy batteries built to a certain spec by other manufacturers and test them. The ones that meet a certain standard of performance in testing are then worthy of the AW brand name and are resold at a premium.

The AW 2000 mAh batt is capable of safely firing down to a 0.7 ohm coil. Tey also have a 1600mAh that can go much lower.

Yikes, now I'm a little nervous about rebuilding using the 28ga. Maybe I'll do a 6-7 wrap and that will be just fine.

Do you have an ohm checker or multimeter? This is not optional equipment for rebuildable attys on mech mods.

I hate to sound like an old fuddy duddy, but you don't want a battery going thermal even once. Trust me.

If you have a decent way to check the resistance on your builds, then you can keep your coils @ 0.7 or higher and vape happily (personally, I'd run around a 0.8-1.0 coil with those batts, for an extra margin, but technically, they can handle 0.7).

Nothing at all wrong with a 0.8 ohm coil on an AW 18650 2000mAh. Quite the fog machine in its own right - you don't need to go super low to get a great vape.

That is, of course, presuming your vendor got legit batts. There's a LOT of counterfeit 18650's running around, and AW is the most commonly counterfeited battery. I don't know how to tell, other than to be sure I buy from a trusted source like RTD Vapor, Orbtronic, or Congrevape.

An AW IMR 18650 2000 mah is safe down to .5 ohms. It's a 10 amp battery. .5 ohms with a fully charged battery draws 8.4 amps.

Congratulations on the new mod. For me, collecting them has almost become a hobby. I've purchased nine in the past six months and I'm using them with a variety of tanks, including RDA's, RBA's and Protanks. My advice is that as you get into coil building, an ohm meter is a good investment. The Sony 18650 VTC4 seems to be a good all around battery.

If you have a multimeter to check your ohms, that will get you by until you have a legit ohm meter.

Ok so I built some 28g coils (5-6 wrap on a 5/16ths bit) and took it in to get tested. I'm at .56 Ohms.

I guess I am on the low side of safe with my pair of AW IMR 18650 2000mAhs. The B&M guy told me I'd be fine with that for now, but absolutely no lower without switching batteries.

So, I built by first atomizer, and it hits like a mac truck and juice has never tasted better (About to try some 6mg Frankenvape) So yay, go me.
