I have an accident with my Mini 3 Pro! I crashed it into a body of water! It was under water for about 30 minutes. I recovered the drone with find my drove. Then I dried it out for four days in a bag of rise. Now, it will not power up under battery power. When I power up using the USB, it powers up and I can connect to the remote. Any suggestions on how to regain battery power?
