Can You Power Led Strip With Battery?

Yes, a battery can power light strips. There are many reasons for using a battery as your primary power source. For instance, they come in handy for cosplay props where space is limited or outdoor camping. No matter the reason, understanding the difference in battery will determine the best fit for your project.

There are many types of batteries, but they all have a few things in common: the voltage that measures the electric flow, electricity, and current. Electricity is the movement of electrons. Hence, the higher the voltage, the stronger the stream.

The current is the amount of electricity flowing in a battery. It is measured in Ampere (A). Furthermore, the capacity is how long your strips last when, hook up to a battery.

Coin Cell Batteries

They are the smallest and can fit in tight spaces. Coin cells comprise 3V. Therefore, these miniature batteries can power one or a few single LEDs. Because the battery is tiny, they store less power, so it is no surprise they can hold 220mAh. These batteries are meant for watches and kid toys.

The set-up will require some soldering skills, but you can find helpful tutorials on YouTube. To calculate how long the battery will last, you divide the battery capacity by the LED loads.

AA Batteries

If space isn’t an issue, then I recommend using AA batteries with a holder. Some battery holders come with a built-in power supply, but one AA can power a LED. A voltage of an AA battery is 1.5V, which ranges between 1.1 to 1.5V depending on how much of the battery you are using.

Most LEDs require a minimum of 2.5–3.5V to turn on. Red LEDs operate at lower voltages, whereas blue LEDs operate at higher voltages. However, if you want your strip lights for a long period, 4 AA batteries in a holder will give you enough juice.

Power Banks To Power Strip Lights

Power banks are handy devices that can charge phones and laptops, so of course, they can power strip lights. Each bank has its capacity like 30000mAh, 1000mAh, 15000mAh, etc. Therefore, if you want to power a 5V LED strip with a  10,000 mAh power bank, the calculation is as follow:

power is Voltage x Current

P is 5V*20mA*20

power =2000mA

now the energy in the battery is 10,000mAh

time (max)=10000/2000=5hours

p(max)=5V*60mA*20

p=6000

t(min)=(10000/6000)=1hr 30min. {Source}

DC12V battery To Power Strips

This type of battery is perfect for campervans when you want to power strip lights all night. It is way bigger than the batteries mentioned above so they last longer plus they are rechargeable. While they look small they can power a car.

How to Choose a Battery for Strip Lighting?

There are a few factors to consider when choosing a battery for your strip light. Look for the voltage, capacity, and connectivity.

Voltage

Having a battery with low voltage can decrease the strip’s performance and will not light bright as expected. There is a light strip that runs on 12V or 24V volt. So it is important to have a battery that has these voltages. You can either have eight pieces of 1.5 AA batteries, to sum up, 12V or two 12V for a 24V strip light.

Never connect a strip light to a battery that exceeds its voltage because you are at risk of damaging your lights.

Capacity 

Capacity measures the amount of power in a battery. It is calculated in watts-hours (Wh) or milliamp-hours (mAh). Similarly, the higher your battery capacity is, the longer they last. For example, a 12V lithium battery lasts longer than a 9V battery.

Connectivity

A battery pack can have either a DC connector or open wiring. Thus, it is essential to know which battery is compatible with your LED strips.

How To Expand Your Battery Life?

There are times where your battery will run out of juice. As a result, you will have to recharge or replace them. Below is a list of ways to prolong your battery lifespan.

Add a Dimmer

Adding dimmers reduce the brightness of the strips saving your battery life. It is easy to connect dimmer switches to your battery pack. Reducing power to your strips not only saves energy but creates mode lighting. Using fewer LEDs can also save on battery supplies.

Add a Switch

LEDs are energy efficient. So adding a switch to your battery supply allow you to turn the flow of electricity off. Because many LED strips batteries use switches, turning off the power will preserve the life of your power supply.

How To Connect A LED Strip to A Battery?

To connect a battery to your strip light, click the negative with the device’s negative ends. Then take the positive terminal and attach it to the positive. It is that easy. With the switch between the battery and the strip, turn the lights on and off.

To recap: powering your strip lights depend on the battery. Batteries with higher capacity will supply more electricity and last longer. The best battery for on the go is a power bank. They are easy to transport and are rechargeable. Moreover, power banks come in a variety of capacities for all your needs.
