Arduino Lithium Battery Charger
6 5v to power up the arduino.
Arduino lithium battery charger. Li ion and li pol charger dc dc boost converter arduino shield provides 6 5v 400ma from single lithium polymer battery. The max voltage v varies with lithium cell chemistry. Please ensure that the baud rate is set to 115200.
The arduino shield is equipped with bq21040 battery charger ic and cs5171 step up dc dc converter. Mount the 4x 18650 battery holder with the marking facing the top of the board. Chemistries ranging from laptop batteries to power tools using lithium cobalt blends and blends containing manganese nickel and aluminum.

The shield also has prototype area to utilize the maximum area of pcb. We will learn how to correctly charge a lithium ion cell using cc cv methods in easy words and in the end of this post you will be able to make a very reliable feature rich yet simple smart li ion battery charger.
When it reaches full charge battery voltage is highest and will not go up much more. The easiest way to connect to the cli is to open the serial monitor of the arduino ide while connected to the charger using a ftdi usb to serial converter. Arduino lithium ion battery charger diy electronics projects in this post we are going to build a smart 3 7v li ion li po battery charger using arduino which is equipped with tons of features with minimal hardware setup.
Remove the 4x 18650 battery holder and drill a 6 5mm 7mm hole. Lipo battery can be mounted on the same pcb. Li po li ion arduino charger shield using bq21040.
Coolmos power battery charger arduino project hub when a lithium battery is charged its voltage goes up slowly. Mark the hole positions with a 0 7mm drill bit or a scribe via the center pin on each of the to 92 ds18b20 temperature sensors. Build a lithium ion battery charger on arduino μf this lithium ion battery charger features a command line interface cli that can be accessed via the arduino s rs232 serial port.
I recommend using a smaller drill bit first.
