 HOW TO make 3.7v LITHIUM battery charger, rechargeable batteries, automatic cut-off

How to make a lithium ion battery charger circuit easily and economically, this very versatile circuit can be used to charge batteries used in mobile devices such as flashlights, receivers, skateboards, positioning lights for bikes..... .

In this video we build the simplest and most versatile Li-Ion 18650 / LIPO 1S Battery Charger using Basic Electronics components with a Theoretical and Practical Technical Analysis, if you want to support this educational work, like and Share my videos.

I have had 18650 batteries from old notebooks for a long time. In order to use these batteries in projects such as flashlights, power banks, 12v batteries with cells in series, etc. I must first know what state those batteries are in.

The first thing is to take them out of the pack and charge them, since there are many 18650s and I only have one charger, I decided to put this together to be able to charge at least 4 batteries at the same time.
