Batteries are an important part of any battery-operated project or product. Rechargeable batteries are expensive because they require a separate charger, but they're worth the investment because they last longer and cost less over time than regular disposable batteries. They come in several different varieties based on their electrode materials and electrolytes—lead-acid, nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer).

Here is the step by step process for making your own DIY 3.7v Battery Charger.

    Get Your PCB Ready!

    Talking about electronics.

    • After making the circuit diagram I transformed it into a PCB design to produce it, to produce the PCB, I have chosen JLCPCB the best PCB supplier and the cheapest PCB provider to order my circuit. with the reliable platform, all I need to do is some simple steps which we will talk later.

    • As you can see in the pictures above the PCB is very well manufactured and I’ve got the same PCB assembled with all the components that we want to use for our main board and all the labels and logos are there to guide me during the soldering steps. You can also download the Gerber file for this circuit from the download link below in case you want to place an order for the same circuit design.
