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!

Step 1: Watch the Video!

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.

Step 2: Order the Components!

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

Step 3: Create the Circuit/Order the PCB

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.
