I understand the oddity of my issue. Let me talk about the 3rd
EVO2 first. I got it 10/16/2020. It Failed 11/4/2020 (total power failure). After the first 2 EVO2s failed, I always checked the battery and aircraft connectors on the third
evo2. There were/are no defects with the charger in all three cases. I always used the charger that came with each
EVO2. The only common denominator, i can think of, between each
evo2 series Flights was high wind velocities, but nothing the drone couldn't handle. I kept checking the battery temps and they never reached over 111 or 115 F when flying against the wind. This heat elevation is minor and should not have caused a fusion between the connectors. By the way, the 3rd
EVO2 was a direct shipment from Autel through amazon. I also made sure the batteries, (which were new) were room temperature before recharging. I never had to force the connections in any way. I even used an electronics air can cleaner on the aircraft and battery prongs to make sure they were clean. I air sprayed the motors and gimbal as well, each time, to make sure all was clear of any debris. Also, this last
evo 2 flight was in 75 F degree weather. I never fly in the rain either. Autel has seen the pictures. They never gave me an answer. They avoid any admissions that could pose a legal risk. The FAA has taken my statement and is highly interested in this case. They are extremely concerned. I also let the BBB know for good measure. Autel would see the pin fusion damage and say stuff like, "you attached an unauthorized piece of equipment on your drone." I didn't know velcro for Anti Collision lights would void any repair or replacement warranty of the drone. All I know is, I didn't burn the prongs. Responding to Agustine: I bought three, thinking it must be some kind of fluke. I really didn't know or was unsure why the 1st 2 crashed. I finally was positive of the reason after the 3rd one crashed. I even bought an 8k for my third one instead of the 6k pro. I thought that would change my luck, but it didn't. I have 6 DJI drones. Two Mavic 2 pros and 1 M2 zoom, the Mavic Air 2, and the Mavic mini. All of them have never failed while flying in the same conditions as the EVO2s. I usually fly the Mavic 2 Pros at 45 mph, unless I need the battery to last longer. The DJI screen alerts me when I push the battery too much, so I simply hover for a minute and let the battery cool down and then proceed with the flight, just at a lower speed. Never, has my DJI collection had a mechanical malfunction. The only malfunctions were my fault. Stupid crashes, nothing else. The EVO 2s in question, except the first one, had never crashed or had hard landings prior to this pin fusion/power failure issue. The last 2 were only 3 and 2 weeks old respectively. Neither had landed harshly or crashed in any way. I flew each, 3 times a day. Never near the ocean. MAYBE, because the
EVO2 series is fairly new and THIS ISSUE IS HARD TO DETECT, UNLESS YOU KNOW TO LOOK AT THE CONNECTOR PINS BETWEEN THE BATTERY AND AIRCRAFT, after a crash, you would never know what happened. Autel would simply repair or replace the drone, and send it back to the purchaser, who would be clueless of the cause of the crash. I just got lucky one day and noticed the fusion of the pins. Funny thing was on the second
EVO2, I was wondering why I couldn't get the battery out. I didn't realize the battery welded itself to the aircraft. When I pulled them apart, that is when I noticed the issue, but I was not sure if it happened before or after the crash. Now, I know , after buying a third
EVO2. The pin fusion and power loss is occurring before the crash. Again, the FAA has been notified. They agreed to investigate the
EVO2 series. They prioritize it , just like any other aircraft. It's interesting how serious they are.
