Hello, I'm at loss for words right now, as I had bought my fly more combo from DJI directly for use on my vacation that is next week, I received it yesterday and took it out to fly after charging the batteries to full, and when coming back inside to charge the remote, it wouldn't charge, it just blinked six times exactly like it was charging then stoped, I tried using DJI assistant to refresh the firmware but that did nothing, I also tried a bunch of different USB cables and power outlets and plugs, none of them worked, I left it on the charger for 12 hours last night and nothing also. DJI support is a joke, they just told me to send the wholeeee drone package back to replace a faulty remote and it'll take 8-10 days and possibly weeks I was told! I can't do that if I wanted to take it on vacation with me, my one option left is to buy one from eBay and have it arrive where I'm going which would be 140 dollars, but I don't know if DJI would even refund me that money if I send the faulty one back to them. Any advice on how to reset the controller manually or how to fix this problem, or what the 6 blinks stand for if it's like a diagnostics code would all be helpful, I attached a video of the plugging and blinking. ANY advice at all is greatly appreciated, as I'm kinda furious right now, because why buy a new product if it's going to be faulty! Thanks, everyone in advance!

Hi AirRandy,
I see that you have Batteries all plugged in at the same Time.

The video doenst show if Batteries are charging at the same time or not, I'm not suggesting that this is the problem, But DJI from previous drones has always suggested not to charge remote at the same time.

Either way, I'm assuming the Remote charger lead is connected to the Supplied charger via the USB port, If this is the case if batteries are fully charged charger may have dropped into trickle charge and not supplying enough current to continue to charge the remote.

I suggest to try to charge remote without batteries connected to charger.  You could also try turning remote on, and then try charging it.
Battery may have also been too warm, and its therefore stopping charging until battery temp normalizes.

Plucking at straws but would be worth checking prior to sending back....

I already did both of those, inlet it charge for 12 hours, like I said and I also contacted support and they were if no help, as I would rather fix the issue then send it back for 8-10 days

Thanks but I kinda used that just as an example, I tried on many other USB ports besides that one

We're all here trying to get your RC back functional for your trip.  Sorry to state the obvious, but...you are using the USB-C cord, right???  The plug looks like an oval racetrack.  Not the flat one side and curved the other plug as in the USB micro.

Yup, the one that was included in box and an Anker one, both charge my phone.

Did you try to charge with the controller turned on ?

Turn Remote on, Then try to charge it. (While its still on)

Did you ever try to charge it off anything other than the power adapter it came with??? Just in case the 5v power port on the DJI adapter was bad.

Yes, and just to check that they would work, all the chargers/and cables charged my phone but not my remote

Hi AirRandy,

That simply is not true, the hub is quite capable of charging the drone's batteries & the RC at the same time, I do it that way all the time (as I did with my MA before)

I'm not sure there is a trickle charge feature either.  The whole idea of after one day the battery discharges down to 96% is to prevent swelling.  Why would at fully charged 100% the smart battery even accept a trickle charge???

The battery hub doesn't charge the remote, However I appreciate what you are suggesting. The Question in regards to charging Remote and Batteries at the same time has been asked many times on DJI Forums and others,  I recall many times it has been suggested or recommended not to charge at the same time by a DJI Admin.

See below post,  as one example

https://forum.dji.com/thread-114117-1-1.html

To my knowledge DJI has not confirmed that it is either safe or advised to charge both at the same time and there are reason for that. 47.22w would be required to charge at full rate Battery and remote at same time. The chargers maximum is 38w

Note: I often charge my batteries & remotes at the same time too, and also have not had any issues. I only suggested that DJI has suggested / advise against it.

From the video, we cannot see if a battery is charging or not, Therefore it could be at the start of the cycle where the current draw from the charger to that battery maybe 2.82A, Therefore not able to keep remote charging.

The Total output of the charger is 38w, @13.2v the hub will consume 37.22w

Therefore, There may not have been enough current remaining to continue to keep controller charging and therefore it shuts off.

I would assume that the charger can balance the load and charge both slower, However I was just trying to suggest that it may be worth a try to charge separately.

The video also shows that the remote does start to charge, it flashes 6 times then stops.  Why ?  My thought process was to advise to try charge the remote separately.  

Not once did I suggest remote and batteries couldn't be charged at the same time, As I stated earlier. I do it. But only when I'm close and wouldn't leave it unattended when doing so.

Hi Rustic17,

I agree re:Trickle charge.  The paragraph that I used in an attempt to explain was poorly written, I was trying to explain that there may not have been enough current to keep controller charging. I should not have used trickle charge to explain.  A lipo charger does not trickle charge,

As I have tried to explain above, The remotes appears to start the charging cycle, then stops.  I have seen my own Lipo batteries for other remote control batteries do similar things, Can be Low current supply, or temp related. I was just trying to backup why I was suggesting to try charge remote separately.

My intent was to try to assist the op as the suggestions I made would be what I would have tried prior to sending back, Specifically as he was willing to try something different so that he could take his new beloved toy with him on holidays.

Your referenced link is not relevant, it has nothing to do with the MA2.  The charger and batteries are completely different. Also, there is no warning in the DJI literature to not charge both drone & RC at the same time.  Obviously monitoring the charger temperature would be a good thing, but that goes for all battery chargers, regardless of their use.

I saw a video from Adlryn from flytpath (YouTube) where he was doing an unboxing and it showed him and also specifically said you can charge the battery and controller at the same time. Now that isn’t saying that is DJI’s official stance, but Aldryn seems to be pretty tight with DJI so I would consider him in the know if anyone is.
