I'm reaching out regarding an issue we encountered with our battery management system. It was functioning properly yesterday, but unfortunately, it has stopped working today. I've noticed that the series voltages are flatlined, and it seems like there's no activity at all. Could you please advise on troubleshooting steps to resolve this issue? Any guidance on how to get it back up and running would be greatly appreciated. Looking forward to your prompt response so we can minimize downtime.
