Pro Battery Charger/discharger

Introduction: Pro Battery Charger/discharger

About: youtube diy creator for now Haha

you need to get yourself these components first in order to make this project so if you feel generous please use my links so i can produce better and more videos

Supplies

Step 1: Get Lipo Batteries

Nowdays we deal with lipo batteries on a daily basis ...especially for us electronic hobbyist we need to know certain charateristics such as battery capacity, maximum current, min/max voltage

so in this project we are going to build a charger and discharger and at the same time it calculates capacity and buzz when it's done

Step 2: Design the Housing

so i used Fusion360 to design the case and then i sliced it with Simplify3d

Then i printed it using my ender3 pro

The total print time took about 26 hours....yeah i know so long Haha

Step 3: Upload the Sketch

I made it easier for you guys

Upload the sketch to your arduino and test on a breadboard at first

This sketch wasn't easy at all for me

It took me one week to write it

So here is it now take it it's free Haha

Step 4: Test on a Breadboard

Make sure you test first on the breadboard

So if there's something wrong you can fix it quickly

Like a misplaced wire or bad connection .

Step 5: Solder Everything

Now take everything and solder it on the perf board

Make sure you always check with your multimeter for short circuit and connectivity

Always check between Gnd and Vcc

Step 6: Add LCD

Now add the lcd and it's potentiometer to control the contrast

And make sure you put some heat shrinking tubing to isolate the wires

Step 7: Solder the Rest of the Components

Now according to the schematics solder the the buzzer the p channel mosfet and the tp4056

The charging module is not mentioned in the schematics but it's easy

Connect all positive to Vcc and all negative to Gnd

Then conect all battery terminal to battery Terminal

And connect each Analog pin to the battery plus , That's it

schematics

Step 8: Combine Everything

Put everything in the case

And make sure you test them before gluing them or closing the case

Step 9: Enjoy Your Project

Now you can use your project and you can calculate battery capacity

Ps: you can change the name on the case if you want to
