Im about to quit smoking and switch over to using a chi you with a rebuildable atomizer... igo-w with 3 coils
I was wondering what the best battery would be for my simple setup ? One that would last atleast half a day (if thats possible) so i could purchase multiple ones.
Ok, first, Drippers aren't a good starter for quitting cigarettes IMO. There is a steep learning curve you have to take. Even if you have a friend helping you, it's best to start off with something simple. When you have a setup, and you need a nic fix, and your dripper is not working, you'll be in trouble, and want a regular cigarette. most success stories about switching to ecigarettes have started off simpler. I'll just list some knowledge it takes to start dripping:
Ohms Law (a must, or your ecig will explode on you)
wicking material (how it reacts to the power you are giving, do you prefer silica, organic cotton, ss mesh, or other)
Juice properties (Pg/VG ratios, nic levels, and if you need a WTA juice to help you quit). Also the simple fact that is that a good throat hit you're getting, or a burning wick.
battery properties. (voltage and amp limits)
wire properties (gague Vs. Resistance Vs. size)
Juice flavors (found a juice you know you like yet? what should it taste like when you are successfull)
Vaping habbits (how often do you vape, are you a chain vaper?)
Also, the general lingo that goes with vaping. For one, you mentioned three coils. on an IGO-W, there are three POSTS. you CAN do a three coil, but that would mean an unsteady vape. your coils are usually positioned near the air holes to allow air to pass over the coils. This ensures no burning for one, and transports the vapor away from the coils. the three posts (one positive, two negative) allow for a coil on the left and right side... or two on the left, two on the right... but where is the third located? is an extra hole drilled on that side?
Switching from smoking to dripping is like saying I want to fly, so my friend is teaching me how to pilot a 747 manually..... It is one huge jump, and can be dangerous if you don't know how to handle certain aspects of it. (yes, I mentioned, a mod can explode if you don't do things right and have the knowelge to take the right precautions).
Now, If I were to assume you know what you're doing, the Sony VTC4 and the Efest purples are the safest and best choices.
good luck.
