Hi received a brand new replacement sealed drone through my DJI care  refresh package but does it have a battery included thanks as not opened the box.

Hi there, could you PM me your case number? I'd like to help you check it. Thanks.

Update:
I've got your case number via PM. As per check, a Mavic Air 2 aircraft & gimbal and camera & Propellers have been sent back to you under the DJI Care Refresh.
