Took off with 58% Drone Battery. About 38 Seconds, Critically Low Warning and landed Mavic Air in Water. I was able to recover. I had DJI Refresh and Refresh Plus. Refresh Plus Expires November 2020…so coverage is active. Sent in Mavic Air to DJI. Sent in Flight Record (which shows fast battery loss - 58% then next line 0%. DJI sent invoice for $69 Replacement. I called. They did not review flight record because they said something about only sending out replacements with Refresh Plus anyway - so no need to check flight record. No explanation on what happened. Joined this forum. Uploaded Flight Record and clearly see massive battery drop in about about 1 second.
Would someone be willing to review the flight record below (it is a short record) and give me their input? I am also curious what I should have expected from my DJI Refresh Plus which was still active. Thank you so much. -Scott
