Series VS Parallel Battery Calculator

Series Vs Parallel Battery Calculator

Welcome to Vaping Hardware’s Series Vs Parallel Battery Calculator!

If you’re using a dual, triple or even quad battery vape mod (yep, that’s a thing now!) it’s often important to know the combined voltage, capacity and current (Amps) of the batteries you’re using to power your device.

We designed this calculator to help you work out just that! Regardless of whether you’re running your batteries in series or parallel configurations, we’ve got you covered!

It couldn’t be easier… Just input the number of batteries you’re using, whether they’re in series or parallel, the current rating (CDR), capacity (mAh) and the voltage of your individual batteries. Hit the calculate button and our Series Vs Parallel Battery Calculator will give you the total combined voltage, CDR and capacity of your batteries!

Please note, if you’re using a mechanical mod powered by more than one battery, you’ll want to take the results from this page and head over to our Power, Resistance & Current Calculator. On that page you can enter these results (and the coil build you’re using!) and we’ll let you know if your setup is safe to vape!

FAQs

Batteries in series combine the voltage while the overall current remains the same as for a single battery.

In contrast, batteries in parallel will combine the total current capacity while the overall voltage will remain the same as for one battery.

Working out whether your batteries are in series or parallel couldn’t be easier. If the mod you’re using is in a parallel configuration, both the positive and negative ends of each battery are connected together or ‘touching’.  For example = + + / – –

Alternatively, if your batteries are in series the opposite is true. The positive end of one battery will connect to the negative end of the other battery.  For example = + – / + –

YES, when using more than one battery in any mod they always need to be used together as a pair i.e. charged and discharged together.

It’s also important to note that the batteries being used should be of the same type and capacity.

The term CDR stands for Continuous Discharge Rating.

It’s the maximum Amps a battery can draw continuously without causing damage to the battery.

The CDR  is a tested value and guaranteed by the manufacturer.

The mAh of a battery is always displayed on the cell itself and stands for Milli Ampere Hour.

It’s basically a measure of the battery’s capacity and determines the time it takes for a fully charged battery to fully discharge.

The standard value of a vape battery is 2500mAh.

Just remember, the higher the mAh rating the more life you’ll get out of your battery.

When running batteries in parallel the current capacities of all batteries in the mod will be combined.

This therefore increases the length of time your batteries will last in the mod before needing to be recharged.

We hope you’ve enjoyed using our Series Vs Parallel battery calculator to work out your combined voltage or current capacity. If you’ve got any questions please feel free to drop us a comment below!
