Training to use XL4015 DC-DC Step Down Adjustable Module?

How to use XL4015 DC-DC Step Down Adjustable Power Supply Module? for beginners step by step.
--------------------------
In this video, I show the correct installation method of input and output wires. After connecting the wires, I use a 12V adapter to power a 5V MP3 player module. I also increase the output voltage to 12 with a power supply and turn on the 12-volt fan. We will measure everything with a multimeter and show you.
--------------------------
Input: 7-38VDC
Output: 1.25-36VDC adjustable
Output current: 0-5A

Best explanation. You zoomed in and out to show every connection unlike other youtubers's video where things are out of the screen and you have no idea what is connected.

Thanks for your encouraging comment. I hope I can help you and others in the next videos.

I always use the 1/3 Amperage principle to protect the circuit from voltage and amperage drift. Plus overheating. At 5 Amps maximum rating according to the datasheets, that calculates to 1.666 amps continuous voltage and amperage output drift. It has worked for me for 25 years without any problems. It lets me sleep at night. LOL

Can i charge 12v 7ah battery with this board ??

[@newtecpro]

no The cost of this reducing module is not optimized for charging the battery. It is better to use the charger module to charge the battery, which has full charge and discharge protection
