Description

This is a work in progress collaboration between all my YouTube users that want to join. https://www.youtube.com/weblearning1

The first video for colaboration can be found here:

This is a smart 18650 BMS with STM32 The Github project is at: https://github.com/weblearning1/STM32-BMS

Please leave your comments below on how to improve the design and I will update it or one of the team members.

Hey, I am not sure if you think of using a charging IC? That has a gas gauge or temp sensor?


Or a MOSFET base controller system?

@naasikhendricks The hole idea will be that the STM32 will do everything that you wrote below without adding a lot of parts. The Mosfet still need to be added.

Hi I had time to investigate the circuit. I have a few questions regarding the voltage divider. Those resistors are supposed to create a PD that at max it reads 3.2v on the ADC.

Hi is this still going - I am looking at trying to get some boards done up.


New to all pcb coding but

@dalebliss There where some people interested but no one wanted to spend time on developing this.
