Hi! You might be better off posting your question in the 'products' section of this forum.  That is way more active.    -   https://forum.dji.com/forum-129-1.html

Hello, there. Sorry for your inconvenience. Please try to follow the troubleshooting steps below：
1. Please try to use a multimeter to check whether the power distribution board is damaged. If yes, replace the damaged power distribution board and see if the issue is resolved. If not, use this functioning power distribution board and replace the battery (a damaged power distribution board may cause damage to the battery.)
2. If the power distribution board is functioning, replace the battery for testing. If there is no error after another battery is changed but the error appears when the malfunctioning battery is mounted to another aircraft, it can be determined that there is an abnormality with the battery’s circuit board. It is recommended that you apply for an Online Repair Request and send the battery back for further testing.
3. Replace the cable which connects the power distribution board and the spraying board for testing.
4. Replace the spraying board for testing.
5. Replace the cable which connects the spraying board and the aerial-electronics board for testing.
6. Replace the aerial-electronics board for testing.
