i have the M2p link with the DJI Smart Controller.

Can’t seem to find the function that allows me to custome the battery discharge in x days.

Has this feature been removed in the recent updates?

I used to be able to set the x number of days in the Inspire, Spark and Mavic Air

That setting is hard-coded to 10 days. There's no way to change it on the Mavic 2 models.

Hi, thanks for the inquiry. Sorry that this feature is not supported on our Mavic 2 Zoom, however, the battery would automatically discharge below 60% if it's idle for more than 10 days to prevent the swelling. Please let us know if you have other concern. Thank you for understanding.
