DJI Mini 3 Pro 47min Battery over heating

[Wild Drone Pilot]

I always have a problem with the heavier 47min battery in sport mode
It only takes a few minutes
Is that the same with all the DJI Mini Pro 3 Drones or just mine?

I haven't had any problems, but I don't fly it that hard for very long.

Sorry I can't answer your question, but perhaps the FPV or new Avata rig would suit your style more?... although if really long flight time is critical, they may not be what you are looking need?

The Avata rig looks nice
I have many DJI Drones and always run in sport mode to get to where I want to video
Never had any problems from any of them
The Mini 3 has no problem with the stock battery
It is only the extra plus size that causes the overload
Looks like DJI may want to offer a larger motor option to go with the larger battery

I've not flown my Mini 3 hard so no overheatinhg issues so far. Is it the drone overheating or the battery? Remember, it's summer and there is no cooling fan in the Mini 3.. No overheating issues with the standard battery flying in sport mode?

But it's so nice to have that extra juice of the larger battery, if for no other reason than ease of mind that there is a lot more battery power to spare even if the drone is up for what I perceive to be an extra long time.

If you are using long stretches of sport mode and the ambient temps are high where you are flying and sun, its possible that you could over-heat any battery..

Or its possible that you have a bad one.. you'd have to perhaps look at a flight log with some of the analysis software or upload it to AirData.com, if you don't have an account, its free and provides quite a bit of info from your logs if you have not used it before, if you subscribe, there are more options.

What's "a few minutes?" Three? Ten?

How are you detecting the overheating? Warning on screen?

Larger motors with the same battery would increase current draw and heating.

I fly my Mini 3P in sport mode quite a bit, large batteries mostly, never had an overheat issue. But I've also not flown it at all in ambient temperature over 85 degrees F, mostly its been under 80.

Larger motors with the same battery would increase current draw and heating.

I'm going to disagree with that a bit. Unless the larger motors were less efficient, it still takes the same power to generate the same thrust, so if flow within the same speed envelope, motor "size" shouldn't make much difference. If the larger motor were also allowed to produce more thrust, and the drone was flown at higher speeds as a result, then sure, it will increase current draw.

Power = Voltage x Current
Thrust is proportional to power minus efficiency.

It was the battery error
Weather was mild 60s mild wind

Good point. I was assuming larger meant more powerful. A physically larger motor with the same power output might even be more efficient and could reduce heating.

Since the ambient temp should not be an issue, and you did not specify whether you were getting warnings on screen or how you determined that the larger battery was having an issue, its hard to say.

Though like I noted previously, if you get the flight logs from one of those events, and run it through some analysis software thats out there, you may get a better idea whether the battery is having an issue or not.. Because of course, if you have battery problems, your may potentially lose or crash your drone.

The time is way off
When I think about it I did not go that far
So maybe a minute if that
But I was recording in 4K at the same time so that is an additional battery drain as well

Overheating within 60 seconds of operation in sport mode sounds like a serious issue, even if recording. Do you have more than one high-capacity battery? If so, does the problem occur with both?

Are the battery contacts clean and undamaged? Any signs of swelling? When the battery is fully charged, what flight time figures are you seeing with the drone hovering immediately after takeoff?

I'd suggest calling DJI.

I have two 47min batteries
I could try both and time it
But I'm afraid I may damage the little guy

Definitely try your other two batteries, the other 47 and the little one. If the problem occurs on both, you have a problem with the drone, if not, you have a bad battery. Don't worry about hurting the drone, just do your tests so you have information for DJI to respond to. There's always a warranty, and they have sent out a few replacment drones.

It's going to take contacting DJI support in any case. They're pretty good, by the way.

Standard procedure for support is to ask for firmware version, and that you install the latest version. Don't forget, the batteries need to be updated as well, one at a time, after the aircraft is updated. Controller may need it too.

The batteries are "smart" containing internal management that affects charging, operation monitoring, and an automatic discharge system to keep them healthy. Lots of stuff in there, and any of it can go wrong.

OK I will do it but I'm still afraid of damaging my little drone

I understand the fear. Perhaps just connect with DJI Support then.
