Lots of questions here. Mod, ohms, and batteries.

I'm considering picking up the FUhattan mod at the local vape shop for many reasons. One reason is i love the story behind it, Another reason is I've heard great things about it. Some more reasons are reasonably priced, looks great, and it seems like a simple mod to use. My questions lie more in coils, rda's and batteries. Im not really interested in any crazy builds like the "Zipper coil" as an example, but more into the simple ones. Im just wondering what RDA should I get to go with this mod, and what batteries should I use for maximum safety. Also, anyone here ever use prebuilt coils? It seems like a great Idea to me. Just looking for some input from experienced moders/vapers I posted this in General vaping Discussion with no help, so im coming here in hopes someone can help.

Welcome, have no input on type of drippers as I haven't tinkered with rebuildables in awhile, but there is a good calculator at steam-engine.org that will tell you if your coil build, measured in ohms of resistance is to low for the power drain rating of your batteries, not really a problem with most mods though. I love my efest 3100 mah 20 amp high drains myself, but a lot of folks love the Sony's too! Good luck and I'm sure you'll get a bunch of great info post haste.

Battery Safety - Read baditudes blogs on battery safety.
Ohms Law - watch youtube videos until you understand the concepts - its important to understand how these things work. For the actual math use a calculator like steam-engine.org

Mech Mods - very little safety built in. You must use your head. Regulated mods are inherently safer, and easier to use. With a mech mod you have to build to the voltage the battery is outputting. With a regulated mod you can try out different builds and crank up the watts/volts as needed. If your build isn't right for a mech, you have to tear it out and start over.

Get an ohm reader - meter your build before attempting to run it.

There's more, but hopefully someone will come by to add more / fill in gaps :)

Just something for you to think about (as HecticEnergy said). With a mechanical mod the only way to "fine tune" your vape is to build a new coil. With a high vv/vw regulated mod (and its buck/boost circuitry) you can "fine tune" with a push of a button. On a mechanical mod your voltage drops as you vape, with a regulated mod this does not happen. Your first hit is just as good as your last hit.

Here's a good read: My thoughts about sub-ohm and latest VV/VW devices...

==========

That said, if you are new to mech mods and/or rebuildables I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader 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:

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.

MECHANICAL MODS & REBUILDABLES

7. Information Resources for Your First RBA
* An essential read and reference guide for someone new to rebuilding coils. Includes a multitude of useful links on battery safety, mod safety, coil meters, coil building, and the differences in the three types of RBA's.

15. Inexpensive Mechanical Mod/RDA Setup
* A response to the frequently asked question on how to get into rebuildable atomizers with a mechanical mod inexpensively. Includes a list of commonly used tools and supplies for rebuilding and where to find them.

BATTERIES - WHERE TO BUY

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
