Once the cells are fully charged, I let them sit for 24h, then measure the voltage again. ... Capacity Test. ... Sometimes IR Test.
What wattage should I vape at 0.15 ohm?
In contrast, the 0.15ohm dual mesh coils have a best recommended wattage of 60-90 watts. Both atomisers offer huge clouds and flavour production. Since these coils are sub ohm / direct to lung (DTL) in vaping style, they are recommended for use with higher VG e liquids.
How many amps can a 0.5 ohm battery draw?
As you can see, with your 0.5-ohm coil and a freshly charged battery at 4.2 volts, the resulting max current draw will be 8.4 amps. If your battery has a 10-amp limit, you are well below the cap. Don’t forget that using a dual mechanical mod in series configuration will double your amp draw per battery, and you will have to build coils with twice as high resistance to be safe. Also note that as the battery depletes, the current will also tail off. For example, when the battery reaches 3.7 volts with the same load, the current will drop to 7.4 amps (3.7 volts / 0.5 ohms)

What is the second Ohm's law?
The second Ohm’s Law formula that can be of use to us is calculating resistance. Let’s say that you have a battery with a 10-amp current limit and you want to determine the lowest coil resistance that you can safely run without exceeding the CDR of the battery.
How to solve for current I?
How did we arrive at that? Look at the triangle and you will see that to solve for current (I) you must divide voltage (V) by resistance (R).
Is Ohm's law magical?
There’s nothing mystical or magical about Ohm’s Law. It’s a few formulas, usually depicted inside of a triangle, and anyone can easily learn and use the formulas with any regular calculator.
Can a coil see battery voltage?
People will argue that the coil will never see that actual battery voltage due to voltage drop within the mod, but to be safe, ALWAYS use the full theoretical battery voltage (at full charge) in your calculations.
What batteries do I need for sub ohm vaping?
The best batteries for sub-ohm vaping are generally Sony VTC 4 or Sony VTC 5 , although they are often out of stock. In that event I usually use an 18650 Efest 35A.
How to keep batteries safe?
Keeping your batteries loose, such as in your pockets, is a good way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe. Get some – now.
What is the maximum continuous discharge rate of a battery?
The most important specification to pay attention to is the “Max. continuous discharge rate” for each battery. Each battery has a number and a letter, either measured as A or C (30 Amps or 15C). Look at the IMR18650-1600 for example. If your battery has a maximum continuous discharge rate of 15C, this means the battery is rated for 15 times the capacity of the battery measured in amps. So a battery that sits at 1600mAh, which equals 1.6Ah will have a max continuous discharge rate of 15 X 1.6 = 24A. There is a chart below which has the max continuous discharge rate in Amps of some common batteries.
How to calculate battery capacity in amps?
1. Calculate your battery’s capacity in amps: capacity in mAh / 1000 = capacity in amps
What happens if you short circuit a mod?
Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your mod, or even your face!
What voltage should a battery be charged at?
Recharge batteries with a resting voltage below 3.6V as soon as possible.
Do you need to test battery volts before use?
However, remember that you’ll need to test the battery’s volts before AND during use in order to make sure that the coil you used is safe.
What is sub ohm vaping?
Sub-Ohm vaping when you build a coil that has a resistance of less than one ohm. The reason you might want to do this to increase the power output of a device that has a fixed voltage such as a mechanical mod or non-variable regulated device. This is really for advanced vapers who “Sub-Ohm” to create more flavor or vapor.
What is the max voltage of a battery mod?
We know the battery is 20A, but we’ll use 19A to give us a 1A margin. We also know our battery has a max voltage of 4.2V on a single battery mod. So the calculation is as follows:
Why do I need Ohm’s Law?
Vaping safety starts with understanding the limitations of your battery. Now that mechanical mods, high wattage regulated mods, rebuildable dripping atomizers, and rebuildable tank atomizers are becoming increasingly popular, it’s in your interest to be safe. After all, you are putting a high voltage or high wattage battery into a metal tube putting it up to your mouth and hitting the fire button!
What does the letter V stand for in a formula?
All that you have to remember is what the letters stand for in the formula; the easiest is “V” and “R” but “I” is a little harder as it stands for intensité (intensity). Described by the French scientist André-Marie Ampère as “l’intensité du courant électrique.”. V is the Voltage of your battery in Volts.
How many amps does a 0.5 coil draw?
So having a 0.5Ω coil and a freshly charged battery at 4.2V, the result is 8.4 Amps of current draw. As your battery starts to drain the current will begin to decrease, which means when the battery reaches 3.6V with the same load, the current will have dropped to 7.2A (I=3.6/0.5)
What batteries are used for box mods?
The batteries used for most mechanical and box mods are either 18650 or 26650. A batteries ability to discharge stored energy is measured in Amps. If you push the battery to its limits the chemicals inside will get hot and start to vent, hot chemicals exiting under high pressure is how a battery blows up!
What is R in a coil?
R is the resistance of your your coil in Ohms. Now that you know the relationship between voltage, current, and resistance you can use the triangle to help build your coils to get the current and wattage you want.
Why is there no wattage for vaping?
There is no ‘best’ wattage to vape at because it all depends on the resistance of your coil. A lower resistance coil will require more wattage than a higher resistance coil to achieve the same vape. It really depends on how hot you like your vapor to be.
How many ohms are in a 0.42 ohm battery?
Using two 0.42ohm coils would come out to 0.21ohm, within the safe limits of a battery rated at 20A.
How many amps does a 0.20 ohm coil need?
For example, a 1.0ohm coil only needs 14W & 3.7 amps to achieve a voltage of 3.7V. But a 0.20ohm coil needs 68.5W & 18.50 amps to achieve the same voltage of 3.7V. A lower ohm build will in turn lead to shorter battery life.
What is Ohm's law?
Before you start building your own coils to put into your vape tank, you should know Ohm’s law. Whether you’re using a regulated mod or a mechanical mod, Ohm’s law gives you essential information about the limits of your build that will help keep your vaping experience a safe one. Ohm’s law is essential to vaping because it determines the amount ...
Why is Ohm's law important?
Ohm’s law is essential to vaping because it determines the amount of amperage and wattage that your build will output which in turn determines if your build resistance is within safe limits for your battery. When these limits aren’t understood or respected is when batteries can explode.
What does R mean in a battery?
R: Resistance. This is the resistance of your coil in ohms. A lower resistance coil will draw higher current (higher amperage) from your battery. This makes calculating resistance essential for building within the safe amperage limits of your battery.
What does V mean in vaping?
V: Voltage. This is the voltage of your battery. When fully charged, a single battery will have 4.2V. As the battery is discharged, the voltage will drop. It’s helpful to think of voltage as “electrical pressure”. In an electrical circuit such as your vape, voltage would be like the water pressure in a hose. High pressure can provide more flow than low pressure. The higher the voltage, the higher the potential amperage.
What is an ohm in vaping?
What is an Ohm. First of all, ohms represent a unit of measurement for resistance, and when it comes to vaping they translate to how difficult is for the electrical current from the battery to pass through the heating coil. The lower the resistance, the faster a coil heats up to a certain temperature and controlling this value is key in delivering ...
What resistances do you use for vaping?
People who prefer mouth to lung vaping are usually the ones who use standard resistances (above the 1 Ohm limit) and those who prefer direct lung inhale use sub-ohm resistances (below the 1 Ohm limit).
How low can coils go?
The coils today can go as low as 0.15 Ohms (in the case of Kanthal) and there are mods out there that can fire even lower so technology is no longer a problem. Also vapers have discovered that by twisting two or more types of wire together they can create complex coils like 'twisted', 'claptons', 'fused claptons' and 'alien claptons' which in terms give an even better flavor.
Why do you need a sub ohm coil?
Because it vaporizes a lot more e-liquid, together with the big clouds, it also delivers a bigger quantity of nicotine. This is why, in most cases, if you're used to vaping on 12mg for instance, switching to a sub ohm coil directly implies lowering the concentration to 6mg or even 3mg. Taking a 12mg puff on a 0.3 Ohm RDA could make you feel very light headed so if it doesn't feel right, go for a lower concentration.
Why are above ohm vapes so popular?
The reason for which above ohm resistances remain popular with mouth to lung vaping is due to the restrictive draw these devices can offer and the similarities with actual cigarettes.
What is temperature control on a mod?
Many of the newer generation mods offer a feature called 'temperature control', which works with Nickel or Titanium coils and gives the user the option to set a desired valued between 200 – 600F. These coils generally have a sub ohm resistances and fire as low as 0.05 Ohms. Because the user can set a desired vape temperature, it has total control on how cool or warm he or she wants the vapor to be, and the feature also prevents dry hits.
What is the difference between lung and mouth vaping?
And speaking about the different styles of vaping, we have two main categories of e-smokers – the ones who prefer mouth to lung hits and the ones who prefer lung hits. Mouth to lung vaping is just like puffing on an actual cigarette, with the vapor going first into the user's mouth and then lungs; while direct lung vaping means inhaling the vapor straight into the lungs.

Somebody please just tell me what is the lowest ohm I can safely use for this battery. Don't point me to some complex crap that I won't be able to understand. I'm new to mechs and I've been reading up on it. But for now, all I need is a simple answer to keep me safe until I learn all the technical stuff.
Haadkoe Senior Member ECF Veteran
Assuming its a rewrapped he2, stay above .25 on that battery and you'll be safe. .20 if you're feeling particularly brazen, but that's pushing it.

No chart that I'm aware of, but as you begin to learn how to use steam engine it will all come together for you. A lot of it comes down to the heat flux, which steam engine will show for any particular build.
Haadkoe Senior Member ECF Veteran
Don't try mounting and measuring the coils independently, you'll probably never get them both to read exactly the same.
