DJI Mavic 2 Zoom mod battery settings. 

You can change some params from old DJI Assistant 2 (1.1.2) if you set it in debug mode. If you use the below parameter mod's the battery percentage does not work and you have to fly knowing your voltages. And no more annoying beeping during low battery or any type of auto landing.  BUT beware, the bird will fly with no indications of low power to the point it will drop from the sky. So know what you are doing if you enable these mod's.
