Hi there!
Quick description. I bought this drone yesterday (Mini 3 Pro) with an included battery. A mate took off with a full battery, flew for a bit, and landed for 1-5 minutes or so.
I took off again at an indicated 79% battery and flew in some moderately high wind, nothing even my old Spark couldn't handle. (On the flight data the battery voltages for this 79% were around 3.6V (per cell) with a deviation of ~0.002. The deviation at the time of the crash was 0.164V with cell 1 @2.35V and cell 2 @2.18V).
I got one alert "battery power restricted", which I assumed was because of the wind (I've had this sometimes where the battery is overworked, so it reduces power).
I checked the battery indicator in that moment and found it to be at ~43%, so it confirmed to me at the time that my thoughts on the battery power restriction was perfectly fine.
Suddenly, (around 30 seconds later), I get an alert that the drone was landing due to "critical voltage levels". I have attached an image of the flight data showing the battery suddenly dropping to 0% from 40% within 0.2 seconds (as well as pictures of the damage done).
I attempted to steer it to where would be reasonably safe. It decended in an open field until about 30 metres of the ground and completely died, crashing dead straight into the ground. The video I was recording got corrupted due to the insanely low battery level, but I managed to save the very last frame of the drone looking downwards, roughly 30m off the ground before it powered off completely. I have attached this.
I have applied for a replacement, but this process can take weeks and I need this drone for a shoot this week. I do not want to publicly share the flight data merely because it shows my private residence. Is there any way I can get a DJI rep to privately assess the flight data to determine this clearly was not caused by user error and send a replacement immediately? I don't see how sending it to a repair centre would aid in discovering the cause as the flight data is definitely sufficient in my eyes, especially for a brand new drone.
Cheers guys!
