in my project I just want the rgb led to change color, when it is low charge, red light flashing, fully charged green light, console in operation blue lightSo you want a battery level indicator that works independently from an off-the-shelf charge/discharge circuit? Also what configuration of batteries do you intend to use? number of cells, and how many series, how many parallel?
I'm thinking of 4 batteries, 2 parallel and 2 in series, I will also use a bms boardSo you want a battery level indicator that works independently from an off-the-shelf charge/discharge circuit?

yes i will use a bms, the rgb led is only one it has 4 legsWell you have to use a BMS board, otherwise you run a very real risk of melting your device. But all that aside, what you're looking to construct is a circuit which includes a voltage senseing ic of some kind, which will be able to communicate with, or directly provide a programmable GPIO that enables you to turn on and turn off 3 different LEDs (seperate bulbs, or do you want to use a 3 color LED for a more space saving design?), and sense the presence of the charging cable when it is plugged into the device.
Have you done any browsing of Texas Instruments devices?
I always buy from Aliexpress, I think I figured out how to do it, I'm studying a chipHave you done any browsing of Texas Instruments devices?
have the LM358NOh really? Which one?
How would you make it work with this chip?have the LM358N
on YouTube there is a schematic, but there are other chips, I'm still watchingHow would you make it work with this chip?
