Battery Safety

Over the past couple of years, "sub ohm vaping" has increased in popularity. "Sub ohm vaping" is the act of using a mechanical e-cigarette device with coils that have a resistance of less than 1 ohm. That is, a tube or box that holds a battery or batteries and does not have electronic protection circuits attached to a device with an atomizer (heating element) with coils at a rating of less than 1 ohm. In order to safely "sub ohm vape", you must be extremely careful, have the requisite knowledge of the electronics, and understand exactly how your electronic cigarette operates.

Firstly, you will need a good multimeter or ohm/voltage meter in order to determine the voltage of your battery and the ohm rating of your coil or coils. This is a very important tool that every person using a mechanical device with atomizers at below 1 ohm needs. Once you purchase the meter, you must learn how to operate the meter in order to achieve precise readings as well.

Electronic or regulated e-cigarette devices are generally safer than mechanical devices due to their inbuilt safety features that protect against faults such as short circuiting; however, if a person wishes to use a mechanical device in a safe manner to sub ohm vape they should ensure they can reasonably calculate ohms law and the discharge rate of their battery.

The mod itself should also be checked for a short. This is easily done by removing the end cap and battery, touching the charging probe to the positive pin in the mod and the negative probe to the body. If you get a reading of less than default on the multimeter then this indicates this mod should not be used for your safety and the safety of those around you.

To do this, you must understand that there is a positive and a negative pin in the mechanical device and a positive and negative connection on the battery itself. This is called battery polarity. Always remember to insert your batteries properly. Battery stacking (placing batteries on top of each other) is never recommended. You should also remove your batteries from your mechanical device when it is not in use as an added precaution. Additionally, if you are using a device that runs on 2 batteries, always mark, pair, and use those batteries and only those batteries in tandem.

A mechanical e-cigarette device does not have the built-in safety features that are in electronic or regulated e-cigarette devices. These devices will run a battery down until it is drained of its power and is very harmful for lithium batteries. Again, you will want to purchase a meter to determine the voltage of your battery.

Next and most importantly, you must choose the right type of battery. Unprotected standard lithium-ion (ICR - lithium cobalt oxide) batteries should not be used in mechanical devices as these have a greater risk of overheating. A good quality protected ICR chemistry battery is a better choice and some would argue that IMR battery chemistry is safer again due to it being less volatile.

And finally, you must also determine whether the battery has the necessary amperage output to safely handle certain coils built below 1 ohm. We recommend batteries with at least a 30 amp continuous output. Many 18650 batteries can only continuously discharge 10 amps and, under certain sub ohm loads, can be dangerous.

This page is simply to serve as a guide to vapers who wish to vape a mechanical device at less than 1 ohm resistance. The Vapers' Edge does not recommend that its customers vape with such a device (a mechanical e-cigarette device with coils at a rating of less than 1 ohm). We only ask that if you decide to practice "sub ohm vaping" that you do it safely. That education should not end here, it should start here. There is a plethora of information out there. Please do your homework before you decide to start to "sub ohm vape".
