Crashed my Mavic and the gimbal broke. Looking to send it in tomorrow/friday asap with overnight to get it checked in for a Refresh! Not sure what to send it in though and what to send in.

Should I send in using original packaging and all the items included? Or only the items I listed? Thanks!

I feel very sorry to hear about your crash. If it's damaged seriously, and the battery is not safe for shipping, then you can send in other parts and take a photo for the battery for evaluation.
And also you can get the information on our website (FAQ 4): http://www.dji.com/service/djicare-refresh/info#s4
