Patching is for earlier models. Use battery type 3, set low battery percent to 10. You'll still get the low battery warning at 10% but it won't auto land. The M2 seems to limit descent rate at critical battery levels which is really dumb. Fly with caution.
So let me ask you this. If I use dji assistant and modify the mavic battery type to 3 on my mavic 2 pro, do I still need to patch it with the link you provided or is that for other drones?
