Ohm’s Law and IMR Battery Safety

In scientific terms, Ohm’s law states that the current that passes between two points in a conductor is directly proportional to the voltage across these two points in the conductor.

In vaping, ohms law teaches you about the causes, the effects, and the limits of how to vape and stay safe. Ohm’s law must be considered when taking into the account of the resistance of the coils and the current passing through these coils. It is the amount of energy needed in order to effectively power your device.

Importance of Ohm’s law to vaping

You may be asking, why is Ohm’s law important when discussing vape devices? It’s important to note that the concept of Ohm’s law needs to be properly understood in order to vape safely, when using mechanical devices.

A typical mod consists of A rechargeable lithium battery, a cartridge containing e-juice, an atomizer, and a sensor. Mechanical devices are not equipped with any sort of sensors, so you must know your voltage, and amperage. This will allow you to calculate what type of resistance your coils can safely use.

A stands for the current in your device. This is the amount of electricity flowing through the device.

V is the potential difference between two points in the circuit.  In vaping devices, there can be a variable voltage setting, and as a vaping device user, it is very crucial to know how to change the voltage and how this act will affect the performance of the device.

R is the resistance to current in the device, which is measured in ohms. Devices used for resistance are called resistors, and they are used to regulate the current flowing across the vaping device circuit. In the vaping device, the amount of resistance will have a direct impact on the amount of power that can safely be achieved with the device.

So, how does this apply to vaping?

As a vaper, Ohm’s law is very essential because it is potentially deadly for anyone who adds the wrong equipment to the device. While purchasing a new battery, it is important for you not to accept face value at its maximum ampere allowance. You should also test your batteries with a testing device.

It is also important to know the amount of current that you can safely run on your device. While customizing a vape, using an ohmmeter is very vital to help you figure out if you are using the correct setup. Your batteries could blow up when pushed above its breaking point.

Whenever vaping goes wrong, it is mostly caused by these rechargeable batteries that vaping devices use. For those that are new to vaping, some of them do not take time to learn the basics of rechargeable battery safety. To properly learn this, Ohm’s law comes to play effectively. Battery and coil safety becomes very easy to understand fully once you understand the basic concepts behind the interaction going on between voltage, current, and resistance.

How to use IMR Battery cells safely

Batteries are one of the most common culprits in accidents involving vaping devices. They are caused by improper handling, overcharging, improper chargers, etc.

Lithium Ion cells have been a source of battery power for most any modern rechargeable device, including vape mods. They have been shown to provide high energy density. Today, lithium-ion batteries are regarded as one of the best and safest batteries available in the market especially when used by vaping devices. This is due to the fact that the risk of explosion is very minimal.

To use these cells safely,

  • It is very important to read the owner’s manual for instructions and recommendations about charging.
  • You have to avoid overcharging. Use chargers that automatically stops charging whenever the maximum capacity is reached. In this battery, there is a small circuit board which protects against over-discharge and overheating.
  • It is very wrong to puncture the battery with a tool. Do not puncture your batteries with a tool while using it because it may cause severe damage to the battery.
  • It is very important to not charge below 0 degrees Celsius. Charging at low temperature can lead to permanent damage to your battery.
  • You have to make sure that you carry your battery in a plastic storage case whenever you are in transit.

In sub-ohm vaping, it is very important to understand the pros, cons, and limitations of the type of batteries you are using. There are some batteries that have low discharge rates while some batteries have high discharge rates. The lower the coil resistance, the higher the required discharge rate. To be on the safe side, it is recommended that you test your batteries, and coils, then, calculate your minimum resistance using Ohm’s law based on your voltage and current, if using a mechanical, or non-digital, device.

Is this process safe?

The answer depends on what type of tank and mod you choose to use. So far, there are some risks involved, but it is not categorically dangerous. In this process of sub-ohm vaping, the risk of getting your batteries damaged due to overheating is quite minimal. There are various types of coils, e-juices and device materials and using only high-quality materials by top-notch vendors can guarantee safety. In order to sub-ohm properly, you have to make sure that you make use of regular mods because of its safety instead of using mechanical mods.

If you choose to use mechanical mods, you have to make sure it is vented properly to allow the battery to cool properly during operation, and be confident in your Ohm’s law calculations. Regular mods are mods that have built-in protections for your source of power and other things such as wattage and voltage. Mechanical mods do not offer any short circuit protection to the battery when user-error arises. “Mech mods” are generally built for advanced vapers especially people that apply Ohm’s law and other factors for safety. Proper use of Ohm’s law will let you know what and what you need to do to ensure safety as you use this device because Ohm’s law is very precise and accurate. When it is done correctly, you can tell the resistance of your coils, the voltage and the current dissipated.


So, there you have it, there are a lot of people who are greatly involved in vaping but do not know and understand the processes by which they can vape safety. These processes involve the use of Ohm’s law, and over the years, individuals have said that using Ohm’s law has proven to be very effective in safe vaping. Vaping device users are encouraged to invest in an Ohm’s meter that can tell you the resistance of the coils in your vaping device and helps you to determine if your setup is safe. There are also calculator apps and websites you can visit to do the calculations for you.
