Let's make All in one Battery Charger

DIY 3.7V Lithium Battery Charger Using Power Bank Circuit:

I made a 3.7V lithium battery charger using a power bank charging circuit. This circuit allows me to charge any type of 3.7V lithium battery, such as 18650 cells or flat mobile batteries.

For the body/frame, I used pieces of wood, making the build simple and cost-effective. To create the battery holder, I used nuts and bolts along with small wooden pieces to hold the batteries securely in place and maintain proper contact with the terminals.

This charger is powered via USB, so I can even charge batteries using a power bank or phone charger, making it very portable and convenient.
