So I was having the system off message and I assumed by battery was going bad since I had issues when it was cold out and it was about 3 years old and about the end of its recommended lifespan. I upgraded to a xs power d4700 to help run my dashcam with the car off. But when I park it's at about 12.1V with the camera cutoff at 12.0V (lowest I can set the camera is 11.8V which I might try) but I read that the xs power with the car off should be or can be 12.7V so I'm wondering if disabling the bms system and having the alternator charge full power and speed 24/7 would be worth it.
Any downsides or negatives? Reduced alternator or battery lifespans? The battery is a deep cycle designed to be drained and recharged so I'm not sure if it will hurt it.

That would be my initial thought. BMS exists to manage those assets as best possible, along with all the other electronics within the car. I also wonder of the immediate impacts, if any system or service would begin acting wonky.

Edit,

I didn't dive too deep into this topic, but I did study the following thread. It has some insight on Pros and Cons.

Specific to the Mustang, the following:

The second thread references disconnecting a specific bit. The initial thread for F150s also highlights a cable or part needs to be physically uncoupled.
