ATOMIZER VS. BATTERY
How to determine what resistance (ohms)
cartomizer for what battery
At SCS Vape, we want to be your go-to vape store, not just for your favorite products, but for information too.
The Chart below shows Volts, watts and Ohms and how they relate to your atomizer/cartomizer.
Let's take an example. You have an eGo battery and you are wondering what resistance you should get for a cartomizer, or if it will work. In the chart you will see values highlighted in yellow, which is referred to the sweet spot. You'll also see a range of values in the RED, which indicated the Danger Zone, the point at which an Atomizer or cartomizer is likely to pop or die.
The chart is setup like so:
• The Top row shows voltage from your battery.
• The first vertical line shows the resistance of the cartomizer (note dual coils need to be doubled accordingly)
Draw a line with your finger to match the ohms with the volts and you'll have your watts, which is what we will be focusing on below. Wattage is essentially “heat” and this is what we take into consideration when highlighting certain areas of the chart in red and yellow.
So how does it work? Lets use the eGo as an example.
The eGo battery generally has an output between 3.7 and 4.2 volts and the cartomizer is 3.0ohm, which as anyone with a eGo can tell you, is quite “perfect”. Looking this up on the chart, you will see that this combo will range between 4.56 watts – 5.88 watts, well within the “safe” zone. So your eGo with the same volts should produce the same safe result and you can vape like a fiend without too much trouble.
Should you put a low resistance atomizer/cartomizer on your eGo? Yes, but you will see the wattage increase quite a bit.
The low resistance Boge cartos are one of the more popular cartos around and it's 1.5ohm and is regularly used on an eGo battery, so while it does seem a little high in wattage, it will still work. Please take this chart more as a guide rather than a concrete yes or no.
Please note: This chart isn't the end-all-be-all, the "sweet spot" is open to interpretation. The danger zone, however, is not. You can easily pop an atty with too much heat. Stay out of the red!
Here is a very simplified table for a quick look:
Battery/Voltage
510, 901, 808
eGo Batteries
3.7v
5v (variable voltage)
6v (variable voltage)
7v (variable voltage)
Single Coil
2.0 - 2.5 ohms
2.0 - 2.5 ohms
1.7 - 3.2 ohms
2.5 to 3.2 ohms
3.2 ohms and up
4.5 - 5 ohms
Dual Coil
NO!
1.5 - 1.7 ohms
1.5 - 1.7 ohms
2 ohms
2.5 ohms
3 ohms
Lower Ohms or Higher Voltage VS. Higher Ohms or Lower Voltage:
Lower ohms
higher voltage
Allows more electricity to flow
Creates more heat at the coil
Creates more vapor
Provides warmer vapor
May intensify or diminish flavor
Will drain your battery quicker
Dry hits are more likely
May cause premature battery failure
Uses more juice per puff - more refilling
HIGHER OHMS
LOWER VOLTAGE
Allow less electricity to flow
Create less heat at the coil
Creates less vapor
Provides cooler vapor
May intensify or diminish flavor
Will drain your battery slower
Dry hits are less likely
Doesn't cause premature battery failure
Uses less juice per puff - less refilling
