The mAh rating will help give an estimate on how long the battery will be useful between charges.

100 mAh = 1 hour. 1000 mAh = 10 hours. 2000 mAh = 20 hours. Etc. Etc.



That is not at all correct.

You should include the current draw in your calculation. A 1000 mah battery would only last 10 hrs if your draw was a measly 100 milli amps. Our devices use alot more than that. A 5 amp draw (which is not unusual) on a 1000 mah battery would only last for 12 minutes of continuous use.

So it would be 1000/5000*60, or 12 min.

.3 ohms on a stock Igo-W is just a waste. You won't get any more vapor at .3 ohms vs. 1.2 ohms. You're going to need a lot more air flow to take advantage of the terrific heat that is .3 ohms, and if you're new, you shouldn't be there anyway.

AIRFLOW, BATTERY AMPERAGE, OHMS LAW, RESISTANCE, VG. Start at NON sub-ohms (1.2 - 1.5 Ohms) and learn about what you're doing before you blow your face off. Good luck to you.

The '100 mAh roughly equals an hour' rule of thumb is for vape time, not constant run time. It does assume standard power use of about 8 watts, so the further away from that you go the more inaccurate it becomes.

The thing is that I don't know where to begin. How do I get my Rebuildables to 1.5? What battery? Do I need a meter?

I've watched boring videos of which they say that they are going to sum up "Vaping and Rebuilding and What You Need to know", but I don't really understand haha

Resistance Wire Kanthal A1. Used to make you coil(s).

Available in these most common five gauges for various resistance levels:

AWG 28: Low Resistance (0.44 ohms/inch)
AWG 30: Low Resistance (0.70 ohms/ inch)
AWG 32: Low - Standard Resistance (1.1 ohms/ inch)
AWG 33: Low - Standard - High Resistance (1.39 ohms/inch)
AWG 34: Standard - High Resistance (1.76 ohms/inch)

Here's a more complete chart:

Kanthal A1 Resistance Wire (AWG 28, 30, 32, 33 & 34 - 3 Feet)

The total length of the wire at a specific gauge determines the final resistance. Once you make a few coils, you'll start to get a feel for how many loops at what gauge to provide a specific resistance. Good luck!
 
If you have safety question's about mods and ohms and amps and batteries and what not, watch this video. It clarified everything. It is a bit long but it gave me a very clear understanding as to how to vape safely with lower ohm coils (I like to vape in the .8-1.2 range).

BEST VIDEO ! Thanks for posting !!!!!! Now I'm getting the whole thing ! :D

A fully charge 3.7 volt battery is in fact a 4.2 volt battery.

so 4.2 volt and a 0.4 resistance = 10.5 amps....

There is of course a voltage drop but you are cutting it to close.... Get a better battery.

Since you are not very experienced in coil building, there is a HUGE possibility that your coil will drop in resistance. Your coil could go from 0.4 to 0.2 without you knowing....

If that happends you end up pushing 21 amps through your 10 amps battery.

Do yourself a favor and get a 20 + amp battery.
 
Well, if you can't identify the manufacturer or otherwise identify it by the letters/numbers on the battery, you can't assume that it is a safe battery to use in a mod. And unfortunately, you can't assume that a Chinese manufacturer/reseller knows enough about batteries to throw in the right battery for free in a kit. Trust me on that. Never use a battery in a mod that you can't identify as safe.

RBA's require using a "high drain" battery, whether you're using a regulated or mechanical mod. When choosing your next batteries, all of the batteries in my above list are high drain. The mAh rating determines how long a battery will last between charges (higher number, longer lasting). Do not use a protected ICR Li-ion battery (they are not on the list).

The Amp rating on a battery determines if it is safe to use for sub ohm vaping. Any coil that is less than 0.8 ohm should use a battery that has over 10 Amp continuous discharge rate. A coil 1.0 ohm or higher you can use any of the batteries which have a 10 Amp rating. RTD Vapor and Orbtronic are two vendors to find these batteries.

The gauge of wire (thickness) and number of wraps to make the coil determine the ohm rating. This will take some experiementation making a number of coils with a different number of wraps to get to the ohm rating you desire. Always measure the coil with a meter. I suggest starting out with 30 gauge wire. I do 6 -7 wraps to make a 2.0 ohm coil with 30g wire. Rebuildables and supplies

You will need to obtain a digital multimeter and learn how to measure your coils in ohms and your batteries in volts. Never fire any coil you make without first checking the ohms and determining with the Ohm's Law Calculator that your battery can safely fire it. All of this info is in the previous links.

This is why RBA's are said to be for advanced vapors. You've got a LOT of personal research to do. I've included a LOT of info you need to know in the links above and in my previous post. I've done half of your work already for you. Good luck, and vape safe.


Hey so I found a a website where they sell the type of battery that I have ...

I got it from my friend. :)
