Connected to Charger Error & Won't Shift Out of Park. Lesson learned: carry a 10mm wrench (to disconnect battery)

How long have you been using the OHMMU battery?
I understand it has its own BMS. Has that presented any issues with the truck's BMS?
Is the OHMMU BMS integral to the battery, or is it a separate device?

I've been using it since January 2024 and have not had any issues. The built-in BMS is entirely separate from the truck's BMS, so they don't talk, and there aren't any problems. Both are working. I know many people have thoughts (positive and negative, no pun intended) on the OHMMU battery. So far, I'm totally satisfied with mine.

So I keep one in my trunk/frunk after reading how people had issues after a software update. Not saying this was the culprit, more that this makes me wonder if we should just do a nice cold reboot once every quarter or 6 months or so. Kind of like back in the old Windows days. I'm 20 years from doing help desk work, but way back in the day it helped if you pulled the power from a workstation, hit the power button while the power was disconnected, then power it back on. A nice cold boot really helped keep the calls down.

So maybe we should disconnect the power cable for 20-30 minutes every x number of months? Just treat this like Windows 95 for now

This may actually be a great suggestion. I have to reboot my iPhone about once per month. What I notice is that random text messages are not delivered. Some come through, but others do not. (Try convincing your wife that you really did not receive the text she sent you.) After a reboot, all the undelivered texts magically appear. I also have to reboot the Xfinity gateway modem / router once per month to solve stuttering TV audio.
