Just got my repaired drone back from DJI about a week ago, looks and flies great ( Thanks DJI) Yesterday I took it out to shoot a few videos and after a couple of flights I have a different problem which happens intermittently with all three of the batteries I have. Very pleased that I noticed this on the ground and not above the reservoir that I flew over!!
Please see the video I uploaded to Youtube which explains the problem.

Hi. We apologize for the inconvenience. Did you try to calibrate the IMU and the gimbal?

Hi, no I haven't done that.  When I get the power to stay on the IMU and compass initialise normally and  both show 'Normal' in the Go 4 app.
When power disconnects there is no connection to the aircraft and no information in the Go 4 app.

The drone turns on. It's just the motor and gimbal that doesn't respond.

Did something happened prior to this problem? Did it crash or suffer from a hard landing?

No the drone doesn't turn on, only the battery turns on - there is no sound from the drone at all. If I push the battery to one side then the drone will turn on, when I let loose of the battery the drone turns off again.
Please watch the video again carefully

I see. If that's the case, we highly suggest to send it to our repair facility and have it check by our engineers. You may start a case online: repair.dji.com or send an email to support.nl@dji.com

Hi,
I just received an email from DJI in Netherlands.
They said 'No crash/liquid damage found. Battery PIN melted of all 3 batteries'.
The cost of replacing all 3 batteries is £468.00 and they are replacing them free of charge.
I am absolutely delighted with the customer service from DJI, just wonderful.
Thank you so much for the diagnostics and thank you everyone who took the time to reply
to my post.
