In this project I will show you how to create a powerful and robust 70W LED panel that can be powered by a Li-Ion or Li-Po battery pack. The control circuit can dim the pure white and warm white 5630 LED strips individually and does not cause any flicker problems due to the fast pulse frequency. Let's get started!

Step 1: Watch the Videos!

The two videos give you a basic understanding on how to create the portable LED panel. In the next steps though, I will give you additional information to make this project even simpler to recreate.

Step 2: Build the Frame!

The first video was all about the mechanical build of the LED panel. You can recreate my design by following the guidelines and measurements mentioned in the video. Feel free to also use the attached reference pictures of my panel. You will need the following materials to complete the mechanical build (affiliate links):
