What happens when your BMW's 12V Battery dies on the road?

Hi all, so when my 12V battery died on the road, I had no choice but to get towed to a BMW dealer since the car was completely unresponsive without it. I wondered if using a lithium-ion jump starter would have caused any damage to the car’s electronics. I wasn’t sure, and I couldn’t find anyone who knew for certain if it was safe to use.

BMW recommends using a flatbed to avoid potential dmg. As for the lithium-ion jump starter, while some users have had success without issues, it's always best to proceed with caution. Make sure any charging cables are disconnected before attempting to jump or charge your battery. I hope this helps.

Thanks! I’ll be cautious, especially about disconnecting any charging cables first.
