How to size a battery box for led lights

Running your LED installation with a power supply is convenient and certainly the easier way to go. However, there are situations where it may not be feasible to run AC cables to your project. This could be because of various reasons such as distance, obstacles, or safety concerns. In such cases, LED strip lights that don't need to be plugged in, and alternative power sources like batteries or solar panels can be considered.

How to size a battery for LED Strip Lights

Batteries are rated by amps per hour so to size a battery for your LED strip you will need to know the following:

  1. The current rating per meter (3.28ft) of the led strip.
  2. Or wattage per meter. Example: 15w/meter.
  3. And the operating voltage - usually 12 or 24 volts.
  4. The length of LED strip required for the installation.
  5. and how long your lighting needs to shine, before recharging.

Example Project

We will use the King Protea Series LED Strip for a cordless light project. The project requires 1.5 meters of strip to run for 8 hours. The example below will show you how to power a 24v LED strip with batteries

Our cut sheet rates the LED strip specifications as follows:

  • Power consumption: 16.5W/m
  • Supply voltage: 24V DC

The Formula

I can now work out the amperage per meter by taking: watts per meter / vDC

Therefore the strip amperage is :- 16.5/24 = 0.6875 amps /meter/ hour

Plus we add a safety factory for power loss at connections and wiring of 15-20%

We will require 1.5meter x 0.6875+20%x8 hours = 9.9ah battery

So as long as we have a battery that is 24v and 9.9amp an hour or more, our project will be successful.

We can help you choose the right size battery for your space by connecting batteries together in series or parallel.

There are many options available and possibilities for us to build a 12v battery pack for LED strip lights - share your project details for us to meet your requirements. We can even create 12-volt battery packs for LED lights with cordless tool batteries available from Home Depot or Lowes. The advantage of this is that the spare batteries and chargers are available anywhere in the country. We advise consulting a battery specialist or one of our sales representatives when wiring LED strip lights to a 12v battery.

  • Battery-powered grow lights

We can build grow LED strip light battery packs using our range of LED strips designed for growing plants - see here

  • Battery-powered Bluetooth lights

Wireless LED strip lighting can be controlled with our low-voltage LED controllers like the Casambi Bluetooth system - Casambi. Casambi ecosystem provides a huge range of control options and the Casambi Xpress works well when you need battery-operated LED strip lights with a remote

  • Motion-activated LED light strip battery-operated

When designing installations like battery-operated pantry lights use our low voltage motion sensors like the motionPAUL. Installing a battery-powered LED strip light motion sensor will prolong the life of your battery power and preserve power for when it is needed the most.

  • Battery-operated rope lighting

Our LED neon or IP68-rated strips are the modern and most reliable solutions for battery LED strip light outdoor installations
