Hi Folks
Im new to the forum.
Purchased a used DJI Mini pro 3 from a youtube content creator.
Is it Possbile to change the battery in the controller ?.Mine holds power for a max of 30 mins. When i check online it states should last around 4 hours.
Which controller?
Also, it looks as though you’re quite new here 
Why not nip over to the Introductions page, and say hello properly and tell us a bit about yourself. 
The simple answer is more than likely yes. I’ve changed the battery in one of mine.
Probably not dead simple .. look on YouTube for a teardown, or battery replacement, video for your controller to get an idea what you’re up against in that respect.
Then it’s getting a replacement battery. DJI don’t sell them.
Depending on the type of battery, somewhere like Bangood is worth checking, though there’s a chance you might find on eBay.
Mr Google and Ya Choob are your friends here.
I just asked Goole for the means of swapping a bettry in a DJI rc n1 controller. You need to find a means of opening a glued case and unsoldering the internal battery (which is a generic type).
Replacing the battery in a DJI RC-N1 controller requires permanently prying open the controller casing, as the battery is soldered to the internal board. Because the repair is complex and replacing the entire controller is often cheaper, most drone owners agree that a replacement is more practical unless you are experienced with small-scale electronics repairs.
If you choose to proceed with a battery swap, follow these essential steps:
1. Sourcing the Battery
You will need a specific replacement battery (often a 18650 or equivalent Li-ion cell) compatible with the RC-N1. Be sure to verify the cell’s model number and specifications before purchasing online.
2. Opening the Controller
The RC-N1 casing is glued and clipped together. You will need a heat gun or hair dryer to soften the adhesive, along with thin plastic spudgers (such as those found in an iFixit Toolkit) to carefully pry the two halves of the shell apart without damaging internal wires or joysticks.
3. Soldering and Reassembly
Once the casing is off, you must unsolder the old battery from the controller’s internal board and solder the new one in its place. Take note of the exact wire routing so that no wires are pinched or cut when you close the plastic shell back up.
4. Battery Conditioning
- Discharge the controller to about 20% to 30%.
- Charge it with an original charger for 6-8 hours.
- Repeat this cycle 3-5 times to properly calibrate the battery properties.
For detailed, step-by-step visual guides on disassembling the RC-N1 and executing the soldering process, you can refer to the YouTube DIY Repair Guides for the controller.
Have you tried the charge / discharge conditioning routine detail in step 4?
Good reply but perhaps check your spelling before posting. If you cannot do that then I would disregard your comments.
Then you may disregard my comments. Is it Goole or bettry that offends the so?
I have never used Ya Choob. Is that something I should know about? Sorry I find flying drones and where I can fly them difficult and I take it very seriously. This is why I am a member of Grey Arrows. It was a friendly comment so please take it as that.
thank you
First drone ive ever owned so no idea about internals etc
It’s where the battery is, and since DJI tend not to make access over-easy, on some models, a teardown vid is your best tutorial.
It’s what I’ve always done when needing to open things up .. RC or the front itself.
Thank you
I found a vid on youtube showing battery replacement on controller.
Without going into detail i dont think i could carry out the job (health probs)..
Will look into a new controller i think.I ca get 30 mins out of current one, So will do for short practise flights.
Which controller do you have, does it have a screen or are you using a phone or tablet
I believe that it is possible to change your battery in the controller. Have a look on YouTube where you can get all the information you need if you feel confident enough to have a crack at diy. If you contact Leicester Drones who have a repair service I believe it may be the better option. The choice is yours.
Don’t know if Leicester drones can help. They are in the middle of a closing down sale 
Thank you, im going with a new or recon controller.Checked out how to replace batteries on youtube and it looks way too fiddly for me to attempt.
Im not the most patient of old fools 
Sometimes it’s easy to take text the wrong way but pretty much most (nearly all) who frequent the forums are friends, helpful and make drone flying fun and amusing. Of course take droning serious but in here, we have the same interest. Only go disregarding something if the information is wrong. If the information is wrong another helpful member will pop up and assist.
Its about having fun, making friends and helping people.
You will probably find someone on here selling a controller
