Batteries losing charge when not in use

[InvisibleName]

Hi Battery automatically discharges when not used for 10 days or so. A fuller explanation is in the mavic 2 pro manual page 34.

Why would they look in the Mavic Pro manual when they’re flying a Mavic Air 2??

for the umpteenth time, this is what the MA2 manual says:

Auto-Discharging Function: To prevent swelling, the battery automatically discharges to 96% of the battery level when it is idle for one day, and automatically discharges to 60% of the battery level when it is idle for five days. It is normal to feel moderate heat being emitted from the battery during the discharging process.

I don't wish to belittle, demean, or disrespect newcomers to our phenomenal hobby sport, passion, etc. In any way. The topic of this post is only an illustrative example of how important it is to ask everyone, new or experienced drone flyers, to PLEASE read the manual anytime you purchase a new drone. The technology of today changes so rapidly from one iteration to the next that it is imperative to understand every element of performance and maintenance else we put the safety of the machine, the pilot, and everyone else near the drone at any point in its flight in danger.

I read that little Manual that came with my Mavic Pro, Mavic Pro 2 Zoom and my Mavic Mini! I learned a whole lot more going on YouTube than what’s in those Manuals!

That is absolutely normal however I own MP MP2 Spark along with Mavic Air2 and in the new flight app I can not seem to find battery settings you used be able to determine how many days a battery should sit idle until it auto discharges very bad to leave Lipo batts fully charged, 50% is best keep them in cool dark storage charge prior to use and allow to sit for about an hour until you go fly never take right off charger and fly immediately it will degrade battery. You have to be careful with your batteries they are single point of failure if it fails you lose drone

That may be the case, but this thread is on a subject that is VERY clearly explained in the manual

And there are more detailed DJI manuals online for their various models and accessories. Between reading those cover to cover multiple times and watching many YouTube videos, knowledge was gained.....as well as reading and searching MavicPilots' forums.

It’s the online manual I’m referring to, available here (for those that don’t know where to look):

lol , dji is famous for batteries losing charge spark, mavic pro even the inspire

And what, may I ask, are you basing this bold statement on?

 

[Dizzydan]

Read your manual and it'll explain why

Maybe it's normal, but it seems after being fully charged and just sitting in the bag a day or two the intelligent batteries are losing a third of the charge. Is this normal? Is there some setting to turn the battery itself off?

The higher the humidity level, the faster the battery will discharge when not in use

Pardon?

That's pretty common with all rechargeable batteries and seems to be be especially true of the Lithium Polymer (LiPo) batteries that does use. My usual process the day before a flight is to charge everything up and check for software and firmware updates. From what I understand, LiPo batteries can lose their ability to hold a charge if they sit too long in a completely discharged state.

I totally agree... We should all read the manuals that are supplied
with our drone, but there are also regular firmware updates done (that obviously can't update our manual). That said, there may be options available to us which allow some features to be improved or changed due to the firmware update. Never a mistake to post a request for any help or concern we may have. No need to keep on insisting "READ THE MANUAL"

Just a point about the manual, it is occasionally updated by DJI, which is why it’s a good idea to occasionally check the download page which, coincidentally, is now a sticky on the Mavic Air 2 Help forum.

Thanks for the info...didn't realize that. Will check online from now on.
cheers

Many of us have not read manuals so no problem Juantana. And this is a good place to ask. On a Mavic Pro you can set the discharge start interval under battery setting is the controller Ap on your phone. So many days of non-use and it starts to discharge. The battery is clever. Not only does it know its three cells' voltage and its own temperature, how many times it has been charged and when etc., but it knows to run itself down as holding a battery at full charge is bad for the battery. Also being left flat btw. It has a tiny element which heats up and uses the electricity until the charge is at the right level. Hence the battery is warm sometimes when not in use.
If you have flown your last flight for the weekend and know you will not be using the drone for a week or two you can always pull the batteries off the charger at a couple of bars and save the trouble. Charge up fully on the morning you wish to go out flying again. Again don't leave batteries dead flat either.
These are truely high tech devices and you will find all sorts of features if you read the manual cover to cover.
All the best for your flying and photography, or whatever your motivation.

Does anyone read the owners manual anymore? Especially a manual for something this complicated. Just about all of your questions are answered in that document that DJI spent a lot of time putting together.

Learning styles very from person to person. It’s part of being human. While some learn quickly by reading text, others need more pointed instruction. Some learn by hearing. I’m an educator, but I learn by being shown, so I always look for videos on the topic. In a nutshell I’m saying give the “read the manual” comments a rest. Just my opinion.

Try to be helpful, not insulting.

Obviously, just watching YouTube videos or reading posts on a website isn’t working. Most new owners don’t even know there are online manuals out there. So telling someone and showing them a link to the manuals is probably the best advice they can get. Not everything that’s in the manual is on YouTube.

Suggesting to read the manual and showing where it can be obtained (as long as given in a polite way) is not insulting.
