You can also open the workshop menu (it's hidden and needs to be activate by wheel button shortcuts, the method is online and post in the forums). It will show the charge level and discharge rate of both batteries, but may be more information than you need.

Thank you for the reply. That is exactly what I am struggling with. The online videos for opening workshop menu are not working for my car. I am pretty sure I have followed them exactly but I am not able to succeed. Do you mind referring me to a post specific to the 2023 C Class for going into workshop menu?
