How to Make 3.7v Battery Charge Protect Circuit

In this tutorial, I will show you how to make your own 3.7v lithium ion battery charger with some of electronic components.

Very easily you'll learn this.

1. Diode 1N4007

2. Green Led

3. Red Led

4. 220ohm resistor

5. 1k resistor

6. Male berg strip

7. BC547 transistor

8. 10k Pot

9. Female usb connector

10. Zero Pcb

11. Connecting Wires

Use this diagram for making this project.

If you want to make your pcb from any website you'll need gerber file.

So, I am sharing gerber file of this project.

And if you design your own Pcb then use pcb pdf for pcb etching.

As a preference I am sharing a tutorial video of this project from my YouTube Channel.

View complete video.
