Introduction: 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!

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.

Step 4: Success!

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

P4056, mt3608, fs8205 and fs312f-g components' libraries are available for Eagle. Do not forget they are not tested. https://github.com/NiyaziToker/niyazitoker.blogspot.com

Awesome! What should I change if I want the exact same characteristics but with an output of 3.3V?

but it s a boost converter ic , i don.t think you can get lower than the 4v or input voltage of i.c

Hello, It is a good project. I have couple of LiPo batteries and I use them on same way but not on one board :(.

I use TP4056 with protection board DW01A and I solve the problem for low voltage protection for LiPo with use of voltage divider on 100 ohms resistor on pin that read VCC.

I see this from one Russian blogger, he use diodes for voltage drop, but I thing why to not add one resistor to ground :).

Stumbled over here looking for PCB tutorials. I always enjoy seeing a new 'ible from you! can wait to see the video!
