Battery capacity tester discharge/charge monitor
Intro:
long time i was harvesting lithium ion batteries from scrap laptop battery packs
it's wasn't easy to test battery capacity manually
so i made this device to tell me the output volt and current of the battery and calculate the battery capacity and life time
Used components :
display used in this project 1602 LCD with shift register 74ch595 to save atmega328 pins
also there is i2c port on the pcb for who wants to add any i2c module but you have to edit the code to fit your needs
for charge and discharge i'm using TIP41C isolated by opto coupler
inquick test mode the circuit using 2 1 ohms resistors 1 as shunt and the other as load
in charge mode using 1 ohm resistor as shunt for current measuring
