Flashlight adapter for installing the 18650 battery

thingiverse

I'm Creating a Custom Adapter for My LED Flashlight Using a Li-Ion 18650 Battery. Here's How I Did It. First, I Began by Gathering All the Necessary Materials Including a 18650 Battery Holder, a USB Cable, and a Piece of Copper Wire. Then, I Carefully Cut the Copper Wire into Two Equal Pieces and Stripped the Ends to Expose the Conductive Metal Inside. Next, I Connected One End of Each Wire to the Positive and Negative Terminals on the Battery Holder, Making Sure They Were Securely Attached with Electrical Tape. After That, I Wrapped the Remaining Wires Around the Flashlight's Body to Create a Sturdy Connection. To Ensure a Smooth Power Flow, I Used a 5V USB Cable to Connect the Adapter to My Laptop, and Then Plugged in the Battery Holder into the USB Port. With the System Powered On, I Turned on the Flashlight Using the Switch Located on the Side of the Device. As Expected, The LED Light Flickered to Life Instantly, Illuminating the Surrounding Area with a Bright White Glow. I Was Thrilled to See My Custom Adapter Work Successfully, Providing a Reliable Power Source for My Favorite LED Flashlight.
