Hello all, I never had an issue with my MA until when during a flight the drone decided do go down like a brick. I was extremely lucky to fly at high altitude and after a drop of 70 m ( 210 ft) the MA regain control and I succeed to recover it without physical damage. I sent the MA to DJI and they concluded the problem is the IMU unit and the drone needs a repair or a replacement. DJI refused to investigate the log file and they just send the invoice for a repair. ( My MA is 18 months old). Since DJI was refusing to help me with a real troubleshooting, I asked for help on this forum. I was very pleasantly surprised to get a lot of help and good advice from forum members. WOW! The conclusion I had from the forum is that the battery is defective.
When I challenged DJI and asked if they are sure the issue is the drone and not the battery they responded very evasively: the MA is not in warranty and they do not care too much. BTW: the MA is in out of warranty, but the battery is 4 months old. For a battery the warranty is 6 months. IMO, DJI is not released from the obligation to give customer support. Even if a product is completely out of warranty the manufacturer is still responsible to give a minimum of support. But this is just my opinion.
Here my question: how can I determine which battery was used during the flight? I never took note, so I must rely on the flight log. Please, anyone could help? I have 3 batteries and it looks like one of them is defective.
Note: as per DJI email a battery is defective if there is a voltage difference greater than 0,1v between the cells. In my case the voltage difference was 0,13V.(see log) The log file is here : https://drive.google.com/file/d/1AcmEMrwKzneKB6xfWQjupPpFVAjmkBeZ/view?usp=sharing The 93 seconds video with the flying brick ( MA) is here : https://drive.google.com/file/d/1cdF1cybojFgi9Z1FdW64ZRejBrl9jB92/view?usp=sharing Any comments will be appreciated, Thank you Pat
