I have 2 batteries for the P4 and the official charging dock. I had left my batteries on the dock in storage mode and just now went to click it over to charge them to go fly in NH. Well there was no response from either battery, they are completely dead despite being stored on the charger. I have tired plugging them directly into the charging cable and again I get no response. I thought it was a defective cable, but the remote is now charging up just fine so I assume something happened to both batteries? Anyone had this before? I already emailed DJI as I bought this in June so it's definitely still under warrantee.
