I was out flying today and I got a message on screen saying battery error and I turned for home it came on and off 3 times then dropped for the sky by luck I was not over people but my drone is dead anyone heard of this before?

Hello and good day Wizzokartworld. I'm really sorry to know what happened to your previous flight with your DJI Phantom 4 Pro. Since this incident happened I would recommend you contact our support team to start up a ticket for the said drone at https://www.dji.com/support?site=brandsite&from=nav . We have the professional team who would do their best to find out the reason of the incident and then the corresponding resolution would be provided. Please note that DJI will not perform data analysis for cases occurring after the expiry of the warranty period; otherwise, valid charges will apply. Thank for your support.

my warranty is expired but the battery still test's as 3 bars and when you hold the power  button in it is showing 4 bars (100%) good battery but is there a danger of other drones falling out the sky? lucky no one under the drone it could of killed them

I have had the battery error warning a few times on my P4 standard. I was able to get back home and land before it fell out of the sky though.

it looks like this is commen fault with dji phantom 4 and 4 pro this is my drone and battery and i found out this is not the first time a phantom fell from the sky?

Yes, this is a known issue and DJI is very quiet about it.
So sad for you. Good no one was hurt.
I look for this every time I fly.
Search posts to see if there is any resolution.
Good Luck.

Not the first this has happened for sure.  I have had the error come up too.  

thanks 1 Eagle i am going to upload all my data pictures and videos and see what is done this is a danger to all at time of crash it was 34 miters up and around 65KPH this could kill this is the first time i have ever crashed a drone
we save so hard to buy them and fly so safe not to hurt anyone and this happens so upset

Send the pics and log to DJI,  even if it's out of warranty.

how do i get the logs off the drone? never done it before and the camera is just holding on with the flex cable

Sync your logs from the device.

arcing is what would cause this, loose connection is what would cause the arcing, ill fitting battery is what would cause the loose connection, i.e not clipped in 100%, just my opinion, Has this happened to anyone with a P4P 2.0 since the battery fitment alert?

I don't think it is arcing.

It is information asymmetry, the only one that knows what's really going on is DJI.  I hope regulators don't allow this to happen in future prosumer and professional drones. There are a couple of things that DJI does not understand and that are well engraved in the aviation industry, one is safety through transparency and the other one is manufacturers actively protecting their client's investment, even in resales.

Hi what fitment alert has there been and I know 100% the battery was fitted properly I've been flying drones for sometime now and I've never had a battery come loose I invest a lot of money into my drones with the hope they would not fall out the sky I am so unsure about flying at the moment

I always think about it too.  Maybe a good thing because it keeps me from flying over places  where I would not want anything bad to happen.

i do most my flying on the beach and not too close to people has you can see from the video i am no close i have a big worries about flying at the moment i know to battery was in propeller and i had done all i could to stop it crashing OK i could have landed it in the field but i am disabled so it would have been so hard to get it and i did think it would be safe to come home how wrong i was

Wizoo, you did nothing wrong. However, equipment failures happen and there's nothing you (or DJI) can do to avoid them. Such failures are extremely rare, not a common issue. No reason for suspicions about manufacturer conspiracy to hide or ignore seldom cases, no reason to predict mass self-destruction of Phantom UAV's. I hope DJI will find reasonable solution for your loss, fly your new machine with no hesitation and enjoy it ...

Well, this is why his forum sucks, it is full of naive people with zero culture about aviation safety. By aviation industry standards the non-disclosure tactics about the ISSUE with the P4P batteries is unnaceptable and this harms everybody trying to do serious business with drones, because them falling like rocks with not a known reason is generally frowned upon by people in the federal admin. BTW, also by industry standards a drone doing commercial stuff falling like a rock is an accident and must be reported, if you are using them in a registered commercial operation, at least in this part of the world. Maybe we should wait for FAA or EASA to finally provide failure models and rates of DJI models in commercial operation. You say they are extremely rare, can you provide a failure rate to assert your comments? The fact is, only DJI knows for sure so I think your comments are useless and mostly garbish.

No, seriously, are you considering a flying selfie camera as an apparatus comparable to a Cessna plane? Are you considering "have a Phantom 4 pro, will travel" advertisement as a serious business plan? Two guys with rusty Toyota and lawnmowers looks more serious as a landscaping business ... And lawnmowers don't fall off the sky ...

How do I download the flight data and view it I would like to upload it on here for advice l will still contact DJI but to everyone that has seen this I must explain some points
I didn't stop and land with the first message because it said signal error but nothing about landing ( like it does if the wind is too high)
I started to make my way home after it came up again but still didn't panic have battery power was still good and not thinking It could drop from the sky
I was dropping height and after clearing the sheep and fence I was going to get lower again not thinking it would crash if I did land in the field I would have had no way of getting it back has I am disabled and couldn't get near it ( I do need to thank the farmer who seen it go down for recovering it for me ) last of all thank you all for your help and support let's hope to get sorted

Tell that to regulators, they are the ones telling me that if I want to earn money with my drone then it becomes an light aircraft more or less; I must be a certified RPAS pilot and I must report accidents and malfuctions to them. Yes, I use an Phantom 4 Pro. Maybe DJI should put a banner somewhere saying ''hey in fact PRO is only a toy with no real commercial application, we will treat you as such''

well hopefully some good news my drone is under warranty and i will be sending it back just waiting for the paper work from DJI i am using airdata.com to get my flight data first
i will keep you all informed this is what i found think someone will know what it is there was lots of it but this is from the first error message

You finally get it! Indeed, as a commercial pilot you're responsible for all decisions and actions involved, i.e. flying above crowd. Which - by the rule - is not allowed for recreational pilots like OP. In both cases the risk of occasional equipment failure is identical, P4P or Boeing 727, doesn't matter. Neither P4Ps or Boeings are falling off the sky notoriously, only some does. No reason for crying when Murphy's Law is in charge ...

i am not a commercial pilot i do it for the hobby

You are the one that does not get it. Comparing safety of a certified aircraft with that of an uncertified RPAS is silly. I am not criticising that a battery failure makes a RPAS to fall like a stone or blaming DJI about it, please re read my comments. Also I have challenged you to produce some sort of data that supports your opinions. I believe that P4P battery problems are quite widespread and it is behind DJI stock issues and discontinuation of P4P, but unlike you I don't have data to support my claim so it is only guessing. Only DJI knows, which is called information asymmetry in my book. We (you, me and the FAA) don't know why they fail, how many or which ones are failing and what is DJI doing to fix it. And that's the real frigging issue here.

That's correct, we don't know statistics.  Only DJI may know how many P4P's were sold globally and how many victimized pilots reported battery mid-flight failure. Naturally such data is tightly guarded. However,  my opinion is based on 5 years long experience, dealing with DJI quads of all kinds, supporting all related discussion forums and talking with many gurus in this business. Your opinion is based on believes and speculations, "and that's the real frigging issue here". Let's get over it because - apparently - my opinion will not change yours, and vice versa.   

All I want is my drone sorted and hope it does not do it ever again at one point i though I was going to kill the sheep I have the log file but not sure how to put it on here i tried to copy and paste the last lines of the log but i have no clue what it all means?

I was hoping to get some help from DJI on here my drone has gone to the DJI Netherlands location and i have had no luck from there in the past

Wow, sorry about your phantom. DJI should replace it. I’ve never seen this problem before and all of your cells looked very close which is good. Maybe it was a defective battery ? Hopefully some one will notice your post who is more knowledgeable. I saw that you did post flight information but do you know how to post the complete flight record ? It would be more helpful.

Just a thought.. in Sport Mode, flying at maximum speed puts more stress on the battery and electrical connections.
It would be interesting to log the failures of these batteries and their owners' flying style. I have a hunch there would emerge a correlation between demanding flight behavior and contacts melting. For instance, sustained flight at maximum throttle in ATTI or Sport modes.
I've had my P4P 2.0 for exactly a year as of next week and I've just inspected the batteries' contacts. They look like new, never used batteries. I rarely push my bird hard. I mostly tool around in P mode. When raising altitude, I do it in steps, allowing cool down of components before increasing another 100 feet. I limit Sport mode full throttle operation to 5-8 seconds at the longest and then slow down.
I wonder how many folks with overheated battery terminals have flown full throttle for over a minute at a time?
And in this particular situation, it may have been possible to fly all the way home by not mashing the throttle in Sport mode. Taking it back at a slow cruising speed might buy enough time to get the aircraft home and landed under its own power.
My opinion is that if you get a battery error, the worst thing to do is try to fly fast. Instead, take it easy, so as not to stress a failing connection or battery cell.

I would now agree with you but at the time I was not sure there was a major malfunction all I was sure about I was getting intermittent battery signal error if you look my footage there's nothing like when is I wind land as soon as possible it just said battery signal error although I turned for home my battery voltage were remaining steady I put the Kraft in2 Sport to get it home quicker I did see the messages and was flying home when the failure happened

I flew about 2 kilometres in sport mode I then did a five minutes flight in gps and set off home in sport after getting home I fitted a freshly charged battery I did  I chan
