Hi, My Phantom 3 Pro controller won't charge the battery  i have to phantom 3 pros and check and test  the batteries  of both controllers but one of them is faulty  i think is damaged , i'm looking for a replacement but i ca'tn find it on any place... any ideas  the battery is a 7.4v 600 mAh 44.4 Wh 2s lipo -ion  battery.

Hi, it's not recommended to change the battery by yourself.
I'd suggest you to contact our tech support at support@dji.com and send it in for evaluation.

Yesterday, I installed the new firmware on my P3P, controller and batteries. I put the RC on charge last night and today it hasn't charged any. Currently it is reading 20%. Everything else that I can tell updated with no problems. In DJI GO the following info: App 3.1.1, Version 1.10.90, Controller 1.8.0, Flt Controller SN 03Z0658370 It appears that the aircraft batteries are charging OK, and NO I dont charge them at the same time. Have you encountered this type problem with anyone else that installed the new firmware? Model GL300C.

When you put the RC on the charger, it does look like it's attempting to charge, correct?

Yes, it appears to start charging. First white light comes on then the 2nd lights up and then it goes back to the first and starts all over again. its been doing this for over 30 hours.

Just to make sure I'm on the same page, you weren't running into this issue until you updated firmware or had you noticed a small decline in battery life in the RC after charging? If it's the former, can you try downgrading the RC firmware via the Go app if the power allows it?

You are correct to assume that I was having no problems prior to upgrade 1.8.0. I'm not saying that's what caused the issue, just trying to provide all the facts. Unfortunately, once you upgrade to the new firmware you cannot downgrade, I tried it to no avail. Also I'm down to about 10% battery. Do you think it could possibly be the charger, even though it still charges the Drone batteries?
According to DJI Mindy:
Notes :
Cannot roll back the firmware version after upgrading to v1.10.90.

There is always the chance that the RC connector on the charger went out. If you happen to have another one to try it out, it would be appreciated. Perhaps a nearby dealer or a buddy with the same unit might be able to help with that as well.

OK, I'll try to find another charger and try it. I'll get back to you in a few days.

Whenever you can would be great!

For what it's worth, I was experiencing a similar issue myself as detailed here: http://forum.dji.com/thread-76528-1-1.html

I found a local DJI retailer who happened to have an old controller battery that was not in use. I took apart my controller (I was out of warranty anyway) and replaced my faulty battery with the retailer's battery and the controller is back to 100% working again.
I wasn't going to wait 4-6 weeks for DJI to diagnose and fix the issue and most likely charge me for it anyway so I did it myself.

OK, I found another DJI charger and connected it to the RC, unfortunately it still would not change. I have obtained an RMA number and mailed to RC back to DJI for evaluation and repair.

Thank you for the update. It's good to hear that it's getting addressed, you'll be up and running again in no time.
