DIY LiPo Charge/Protect/5V Boost Circuit

In this video I will show you how I combined a couple of ICs in order to create a charge/protect/5V boost circuit for a single cell LiPo battery. Along the way I will show you how I designed the PCB, how I ordered it and what kind of problems occured while soldering the components and testing the circuit. Let's get started!

The video gives you all the information you need to create your own Charge/Protect/Boost circuit. In the next steps though I will present you some additional, helpful information.

Here is the parts list of the circuit with links to where I ordered them.

Here you can find the schematic of the circuit and the Gerber files. You can use them to order the PCBs with JLCPCB: https://jlcpcb.com/order/pcb

Or you can simply open my EasyEDA project with my board design and click the fabrication output button: https://easyeda.com/GreatScott/LiPoChargeProtectBo...

Once you receive the PCBs, all you have to do is solder the components to it with the help of the schematic.

You did it! You just created your own LiPo Charge/Protect/5V Boost circuit
