I'm thinking it has something to do with the IMA battery.
The brake + battery light went on after I floored the car and went full assist.
This time it didn't shut off right away like it normally does after a few minutes. I then must have been running off my 12 volt battery. I drove for a while and even left the lights on with the car parked for a bit. This drained the battery eventually.
This is why I'm going to rule off a bad 12 volt battery, because the battery held up for a while.
I then need to find out the issue about the battery + brake light coming on. I remember reading a post about this issue on the forum, I need to find this post as it was an IMA related warning.
I will also use my grid charger and discharger, and run a cycle or two with it as I don't do this often at all anymore.
My IMA battery is getting old as I believe it was replaced once, and before I had the grid charger I was getting error codes a few years back. So the battery is not exactly in the best condition and probably needs to be grid charged a few cycles.
