Hi,

I like to buy a second Mavic Pro bat like to know what firmware it have out of the box.
This one is manufactured on 13 th of July 2017.

Thanks.

I don't think there is any way of knowing what firmware will be in the battery. When you buy a new battery and it is not the latest firmware then you will receive a notice in the DJI GO 4 app that thee is a firmware mismatch and give you the option to update it. It only takes a few minutes. But you do need access to wifi or cellular data.

We could not predict the firmware the drone will be at. You can check the firmware info if you received the drone.

As Jenee 2 mentioned, there will be reminder when the different firmware were detected. Please update the firmware according to the directions.

Thanks for the info, by the way it's the firmware from the drone not from the battery i like to know.
