How do I know what wattage my vape is?
Really, the most useful formulas for vapers, are the three that calculate current (I = V ÷ R) power (P = V x I) and resistance (R = V ÷ I). These will allow you to figure out the current your coil will draw and the wattage that will result. As you increase resistance, current and power will drop off.
What amp is 18650 battery?
How much power does an 18650 have? A 3.7v a 3400mAh 18650 stores about 2 aH to max of 3.5 aH. It can store about 10 to 13 watt hours. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour.
What is a 510 battery?
A 510-thread vape battery is a device that is used for vaporizing, either cannabis or nicotine. While the term “510” has become a generic name for vape pens and their parts, the name originates from one of the first e-cig manufacturers.
What mAh is best for vaping?
For low builds on a mechanical mod, the 20S is the only battery that can safely deliver up to 30A without overheating but we recommend only using it at up to 20A for maximum performance. Keep in mind that with a 2000mAh battery, you're best to get two and a battery case so that you're never without your vape.
Does mAh matter in vape batteries?
The higher the mAh rating, the higher the capacity of the battery and, depending on power drawn, the longer it will last between charges. Most non-adjustable vape batteries output 3.7 volts.
What does 3.3 V mean on a vape pen?
In general, most slim vape pens will be in the lower 3.3v range. This is the correct voltage for most oil cartridges but does not provide enough power for ceramic or wickless cartridges. These types of cartridges offer better vapor quality and produce more vapor, but require a voltage of 3.7 or higher.
How many Vapes explode a year?
Between 2015 and 2017, there were about 2,035 explosion and burn injuries caused by e-cigarettes, according to a report published last year in BMJ Journals. Researchers noted that the number was likely an underestimate given the difficulty of accurately tracking incidents.
How many volts does a vape battery have?
They provide nominally 3.7 volts of power, 4.2 volts when fully charged and slowly discharge when used. Once the vape battery is discharged below approx 3 volts, they must be charged again.
How many charges does a vape battery need?
Approximate number of recharges a vape battery can undergo before it’ll no longer hold a charge. Duty cycles can be as high as 500 charges but will vary depending on the specific battery type.
What is the anode of a vape battery?
Most external vape batteries are Lithium Iron (li-ion) and consist of three parts: the cathode (+), the anode (-), and the electrolyte (bit in the middle). The anode of all 18650 li-ion batteries is basically the same; carbon/silicon and graphite.
What is the circuit board on a vape battery?
Batteries have a small circuit board, usually on the bottom of the vape battery, that stops the charging or discharge of the battery in certain circumstances, such as Over-Charge, Over-Discharge and Short-Circuit. These tend to be slightly longer because of the circuitry and are normally classed as ICR.
What is the difference between a mechanical and regulated mod?
A mechanical mod takes power DIRECTLY from the vape battery, which means it’s important to know that the battery is capable of providing the current required to fire the coil.
What is an unprotected battery?
Unprotected batteries are normally classed as IMR or INR. Both Protected and Unprotected batteries come in either ‘Flat Top’ or ‘Button Top’. This means that the positive electrode (end) of the battery is either Flat or Button, with most mods using the ‘Flat Top’ type.
Why does my phone battery overheat?
Using a different cable to that which your device came with can damage your battery. This is because the cable may have a higher voltage than your battery which will cause your device to overheat.
How to find how many amps a coil draws?
If you simply want to know how many amps your coil draws from you battery click here, enter the resistance of your atomizer and the voltage of your battery and press on calculate. You can see the amps in the "Current (I)" field.
What does C rating mean on a LiPo?
So what does the C rating on a lipo mean? For starters, the C in C Rating stands for capacity. To break it down to its simplest terms, the C rating is the maximum safe continuous discharge rate of a pack. If you see 10C on your battery, it means it can be discharged at 10 times that pack's capacity.
What does 10C mean on a battery?
If you see 10C on your battery, it means it can be discharged at 10 times that pack's capacity. Capacity refers to the milliamp-hour rating of the battery, which will be listed as a number followed by mAh (2000mAh, for example).
Does every electronic device have an amp limit?
Every electronic device has an amperage limit. The outlets in your house, the batteries you use, the USB port on your computer, USB adapter, think you get the point. This dictates how high of a current you can run. This limit works in conjunction with the cell's amp limit on pv's.
What is a vaporizer battery?
A vaporizer battery is nothing special. It’s nearly identical to the battery you keep in your pocket year-round, inches away from your genitals. I’m talking about the lithium ion in your cellphone. The same type of battery you’ll find in your laptop. And your tablet.
What is the maximum amount of current a battery can draw?
Also known as an amp limit, a battery’s CDR is the maximum amount of current (amps) that you can continuously draw before it heats up to dangerous levels (usually above 75° C). Think of it like a powerlifter trying to lift his weights too quickly. It’s bound to lead to injury.
What is a LiPo battery?
Then there’s the LiPo (Lithium Polymer), which can be found in many DNA devices (like the VaporShark or Lavabox). These battery packs stack multiple lithium ion cells in a protective polymer casing. They can also be found in cordless phones, RC cars, and power tools.
What is a smartphone lithium ion?
Your smartphone uses a custom-designed lithium ion, chosen specially to meet the physical demands of the device. It is tested thousands and thousands of times in the most stressful conditions your phone can produce. And then it’s tested some more.
Can a series circuit be completed if one battery is missing?
A series circuit, on the other hand, cannot be completed if one of the batteries is missing. This is because each battery acts as a connection in the main circuit.
Do you need to have all the batteries inserted to complete a circuit?
Simply put, each battery running in parallel has its own positive and negative connections to the main circuit. So you don’t need to have all of the batteries inserted to complete the circuit (and fire your device).
Can you push a battery past its amp limit?
Exceeding amp limits: there is no reliable method for your device to check your battery’s amp limit. So there’s nothing preventing you from pushing your battery past its safe limits. It is your responsibility to choose a battery that can handle the current required by your vaporizer.
What does CDR mean in batteries?
CDR stands for Continuous Discharge Rating and is basically the rate at which amps can be drawn safely from a battery without it overheating. The CDR value of your batteries can be found either on the battery or in the manufacturer’s specifications.
Is vaping safe?
Battery safety is potentially the single most important aspect of vaping, regardless of the vaping device or setup you’re using. The good news is that VAPING IS SAFE as long as you understand battery safety ….
Can you use a battery with a higher CDR?
You will need to use a battery with a higher CDR value. Alternatively, if you don’t plan on EVER using the maximum wattage your device can produce, you could reduce the Vaping Power input to the maximum you’ll vape at while using the battery you have. We hope you enjoyed using our battery amp draw / drain calculator!
Can you use batteries with a lower CDR rating?
This is to make sure the batteries you use can safely deliver the power needed to vape at the maximum wattage available from your device. If you only plan on using a fraction of your mod’s available power, you could potentially use batteries with a lower CDR rating.
Understanding the types of vape pen batteries
The primary purpose of a battery in a vaping module is to heat the oil from the cartridge provided to convert to smoke. The battery does not have to be too powerful for this function. Vape batteries can be internal or external. Each of them poses a few pros and cons.
Vape battery – Decoding the different sizes
External vape batteries are available in different sizes. Among these, the most popular codes are 18350, 26650, and 18650. New designs also have batteries of codes 21700 and 20700. The first two digits of the code refer to the dimension of the battery measured across, and the last three indicate the length in mm.
510 Threaded Batteries
The 510 threaded batteries are the most commonly used style for vape pens in the market today. Except for pods or other larger batteries, most portable vape pens use the 510 threaded battery setups. Although the 510 threaded battery style is typical for most cartridge types, some cells can be too powerful for a specific cartridge setup.
Choosing the right ratings
As discussed, a critical characteristic to determine the right battery for your mod is to evaluate the current and capacity ratings of your battery. Two features indicate how effective your battery is for vaping. The total capacity of your battery is available in the mAh rating, whereas the Amps rating gives the discharge rate.
Tips to enhance your battery life
Now that we have discussed quite some information about vape batteries, we will continue to explore ways to utilize them well. Using and maintaining your battery well ensures you can use your vaporizers or vape pens for a prolonged duration without any worry. The typical battery cycle for any rechargeable battery is 500 charges.

Best Vape Battery: Safety Tips & Best Practices (Beginner & Advanced)
This post is LONG. But if you’re new to vaping (or use mech mods) it is 100% required reading. YOU DO NOT MESS AROUND when it comes to a vape battery. Period.
Pulse Ratings are Useless
Have you ever considered using a vape battery because of its high pulsed current rating?
Six Reasons Why Not to Use the Pulse Discharge Rating
It is not within the intended operating parameters of the battery. It’s akin to running your car’s engine in redline mode all of the time. You wouldn’t do that to your car, so why do it to your battery?
Mech-Mods & Vape Battery Safety
You might say, “My vape buddies and myself are running a 0.1 ohm coil on our mechs. We’re using a 40 amp battery. And nothing bad has happened yet. We be blowing dem clouds.”
What is the best ohm for vaping?
The best ohms for vaping depends on how you like to vape. Lower resistance builds (like those less than 0.5ohm) will require more wattage and this generally produces a hotter, more intense vape. Builds over 1.0ohm will require less wattage and will deliver a less intense vape.
What is the lowest resistance for a dual battery mod?
For a parallel mechanical mod with dual batteries, each rated at 20A, the lowest safe resistance is 0.11ohm. But to ensure that you remain safe, build a bit higher; 0.12ohm would be better to ensure that you’re vaping safely within the limits of your batteries and not stressing them.
How much resistance is needed for a dual coil?
NOTE: A single coil with a resistance of at least 0.42ohm is safe for the build above. But If using dual coils, each coil must have a resistance of at least 0.84ohm. This is because a dual coil build using two coils that each have a resistance of 0.84ohm will come out to 0.42ohm.
What are the three elements of Ohm's law?
Ohm’s law uses three essential elements for calculations: voltage, current, and resistance. These are typically depicted in a triangle with V, I & R. If you know two of the three, you can find out the third: V: Voltage. This is the voltage of your battery. When fully charged, a single battery will have 4.2V.
What is a versed vaper?

Is voltage like water pressure?
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. I: Current.
Is 0.25 ohm safe for series mods?
This build of 0.25ohm is not safe for use with series mechanical mods because it will pull 33.60 amps from each battery. Most batteries are only rated to 20A or 25A. A much safer build for a series mechanical mod would be 0.5ohms:
What batteries are used in vaping?
The most commonly used batteries in vaping for GOOD REASON (Due to their High Drain Rate due to their chemical makeup and better “Amperage Rating” which we’ll cover below.) by far are the 18650 and 26650 batteries.
What is the constant amp rating?
There are two Amperage Ratings, one is the “Constant” Amperage Rating which is how many Amps a battery can handle CONSTANTLY (Firing constantly aka holding the fire button.
Why do batteries have holes?
Batteries are made with a protection system where if there is any intense temperatures, shorts or problems, the battery will “Vent” it’s chemicals and starts smoking to release the pressure within the battery instead of potentially building pressure, that might make the battery explode.
Can you put batteries in a device?
NEVER blindly place batteries in your device, always ensure you are properly installing them and NEVER place batteries in a device/charger backwards or improperly! NEVER place batteries near or on top of any kind of metal objects, such as a table, laptop or freezer!
Can you keep a battery in your pocket?
If you are unsure, it’s best to get NEW batteries or have an experienced individual re-wrap your current batteries. NEVER keep extra batteries stored without a case or carry them loosely, a single piece of metal touching the contacts of a battery can cause it to discharge in your pocket. ( Buy a Battery Case!)
Can you remove battery wrapping?
NEVER remove the wrapping from a battery or use a battery with damaged wrapping where you can see the exposed metal of any kind. An unwrapped or damaged battery is guaranteed to be a potentially dangerous battery. Inspect your batteries! If you are unsure, it’s best to get NEW batteries or have an experienced individual re-wrap your current batteries.
Can you overcharge a battery?
DO NOT: DON’T ever trust a charging source to not overcharge a battery (Including internal batteries charged via USB!) This is strictly a safety precaution as batteries heat up when they are being charged and one shouldn’t trust their charger not to potentially overcharge a battery, even if it has a cutoff.
