low battery auto-land can be overridden. Even though it begins it's decent at 5 or 10%, you can hold the climb stick up and it will climb. If you let go, it will start landing but you can force it to stay airborne. Also, it will fly at 0% battery remaining. I didn't fly long, basically hovering and quick climbs & maneuvers to see what it would do but you can fly beyond 0%. The cells were half in the red-zone so I don't imagine there's much of anything left at that point but good knowledge for people who like to push limits.
