Just bought the DJI mini 2 & it’s my first ever drone I feel overwhelmed with the amount of info coming at me through the videos I’ve been watching! Thought I was just going to buy & go have fun
Same here man but hey these vids help us a lot.
Btw dji already launched their update firmware. The battery problem is now fixed
You need to update using the dji fly app each battery one by one. Hope i helped u. Cheers!
Rick, I wish you had been my science teacher 50 years ago. Nice job, and I don't even own a drone !
He reminds me a little bit of Mr. Wizard lol
Al, thanks for the post and I'm flattered. I just love tech and investigating these types of details. Stay tuned for more clips posting soon.
@@digital4282 Telvana, I appreciate the post and was glued to the TV every time that guy was on so I guess some of it rubbed off on me. Stay tuned for more content posting soon. Rick
Too hyper.. sounds like a car salesman or a youtuber for younger kids. All that's missing is him shouting.. HI GUYS welcome to my channel don't forget to SMASH that like button...
@@nubie1100 Bob, thanks for the post and I do the best I can with these videos. I get pretty excited talking about tech in general and I'm just trying to pass along useful information to help you with the gear. The real question is - Did you lean anything? If you did then I'm happy and feel like I've done my job. Rick
Excellent and informative video! Knowing why these batteries do this is incredibly important to many of us. Thanks!
This is the first video of yours that I have seen...I enjoyed it and found it helpful....but please slow it down a little...I subscribed and "liked"...I hope I can keep up with your pace...thanks for the info!
Mark, thanks for the post and I'm glad you found the content helpful. I also appreciate you subscribing and welcome to the family. I'll have a lot more content posting this week so be sure to stay tuned. Rick
Always great information. You did it again!! Thank you, sir.
Thanks for the technical background. The idea and solution with the "firebox" is great.
Many regards

Thanks for the post and I'm glad that you enjoyed the clip. Consider subscribing to the channel so you won't miss any of the new content I'll be posting this week. Rick
A quick fix is to use an elastic band. Place the batteries in the holder the right way around and put an elastic band around the top of them where the terminals are. This stops the batteries falling into place and because it’s elastic when you take one out it holds the other two in place.
Gary, thanks for the post and that's a great suggestion. I have a few other pilots I fly with and they use a heavy-duty rubber band to do a similar thing. Anything that keeps the batteries from falling all the way into the socket is a good thing until we see a firmware update to sort out the logic.
Good one
I’ve been using LiPo batteries for years and consider myself to have a good grounding on them . Congratulations on an excellent video, very well presented and pitched at a novice to knowledgable person. I think is very helpful for those getting or got the Mini 3 Pro.
great tips for storing the battery's ,l like the backwards one in the charger
Great video I have seen more on this issue. I took mine out of the charger and drone.
Mine havent discharged in 5 days, I hear DJI have admitted there is a fault and will be issueing a firmware update shortly
Great video Rick, I bought a brand new Phantom 4 Pro that came with a dead battery cause it sat in the box too long and it went into permanent hibernation. Nothing more frustrating than a 150 dollar paperweight 😁
Love your teaching.... very well explained!
Good point on how they will fix that but didn’t thought about flipping those batteries; thanks so much keep them comming! Fly safe
this was great info because i was concern i just got my mini 2 combo last week have not used it yet. thank you so much you were great , can't wait to fly !!
AWESOME! Thanks for the info. You should be a science teacher. I was just having this discussion with my son a few days ago. Now I know the science behind it. Keep the videos coming.
That is awesome! I love diving into the nerdy details of what makes things tick and can't help but talk about it on the channel. It's great you're sharing that with your son. I do the same with my kids and it's really important in this tech-driven world they'll be living in. Stay tuned for more geeky topics soon. Rick
For an owner of the mini 2 for less than a week, this is good for me. Thank you
The clarity of the voice makes the difference sometimes.like this one.
Maybe it’d be helpful to edit the title of the video adding the issue has been fixed by DJI.
From the recent comments and the ever more exposure to the drone market, people may find this video confused, but the video still serves as part of the history
That's good. What have they done differently
I admire you so much Rick ,you are BRILLIANT .
Good information Rick.
I have placed the LiPO batteries into the hub, but not clicked them in all the way. After a couple days, I pushed them all the way in and they were all at 3 lights after starting fully charged at 4 lights. I hesitate to put them in the hub backwards for fear of warping the hub. Maybe a problem, maybe not.
Anyway, that's what I found...
Thanks for your great information....
Dennis, as long as they are not fully inserted into the hub and making contact, they will discharge as normal. It's only when they touch those contacts that the battery has to stay "awake" in case the power button is pressed. Thanks for the post and happy flying! Rick
Thanks for sharing. DJI has advised me to remove batteries from the Drone or Charging Hub when not in use
Thanks Rick, I plan to remove my batteries from the charger NOW. I had no idea they needed to be loose to activate the auto-discharge😂
Thanks for the post and if you've updated to the latest firmware on the batteries they should now auto-discharge in the hub. Try updating and testing the feature and you may be alright. Rick
i just bought mini 2 fly more combo today, and one of the three battery not charging and blinking three times when charging, when in the charging dock and when charged in the drone. any solution please help
Shorted
Very informative! Thank you! Like the other fella said be nice if you spoke a bit slower for those of us who aren’t as speedy ! Otherwise many thanks!
Good info. But my issue is my Mini 2 nor my controller will not turn on. All batteries are charged up. Push the button to turn on and the lights light up and then go out. Nothing will turn on. Any ideas?
Harold, I replied to your other comment with this solution - hold the power buttons until the LED's strobe all the way up and you'll hear a tone to turn the drone and controller on. Try that and let me know if that's the fix. If not, we can try something else.
You can’t out batteries of the Mini 2 in to the hub backwards on all models I guess because mine won’t do that. There is a tung and grove feature there to prevent the battery from sliding in all the way. So I use a fat rubber band around the contacts of the hub and then slide batteries in normally.
Mine has the line and groove too but with enought force it will go in backwards :D
Thanks for this amazing video. I got a New Dji mini2 (Fly more combo) but, one of the batteries is not charging, it constantly blinks two lights. Solution to this will be very much appreciated. Thank you.
How to put the batteries backwards in the charging hub tho there is a plastic line on the inside which prevents that to happen?
That rib makes it a little tight but they will slide in OK after a few tries. You can also use a rubber band on the top of the batteries to keep them from fully sliding into the holder. The key is to prevent the contact from touching so they can auto-discharge when now in use. The best idea is to pull them out of the charging hub when you get home and pop them into a Lipo bag for storage. Thanks for the post!
@@Dronevalley make sense i guess thanks for the answer
I'm sold on those battery covers.
2 year old Mini 2, and leave my batteries in the hub for a few months at a time , and they auto discharge fine. I don't fly a lot, but when I do, I charge them all fully until all lights are solid. I have 6 batteries. I keep it even, 8-10 charge cycles each battery and I have zeros problems so far.
"and how to fix them" i have a new never used mini se battery that is not charging and need some help, wasted 15 minutes to wait for you to explain the fixing part but never got any help
Hello kind sir, I finally got the correct video showing how to charge both battery & controller usung the mini hardware. The video I had posted was as you stated charging the controller using a battery to do so. This one is physically increasing the voltage on the battery & the controller at the same time. Sorry for the bad video. Ray C. Florida
I have the original Mavic Pro battery. Any suggestions on an easy way to wake up the battery after it has gone to sleep?
Great video! I do have a question. If the mini 2 battery is between 40% and 65% can we leave it in the drone/cahrger?
New drone flyer here! Just started with a Mini 2 and loving it but definitely overly conscious and cautious about the battery life, especially since I bought it used. Was there ever a firmware update for this issue?
Welcome aboard! Yep, the latest firmware fixed this issue. Be sure to check the DJI site for your drone under the "downloads" tab to make sure you're on the latest. Also, when you do the update be sure to rotate all of your batteries through the drone. They each have controllers inside of them (smart batteries) and may need to be updated as well. I hope that helps and be sure to sub the channel so you don't miss anything.
Hi, what did I do wrong? I charged all three batteries in the charging hub all morning, went to a birthday party in the afternoon that I was going to film… And my charging hub discharged all three of my batteries right down to critical position, The first time this happened it discharged one battery, this time it discharged all 3, Not sure why this happened, I think I have the latest battery firmware, Thanks… I love your channel
Great explanation!!
Thank you! I'm want to use this for prospecting, so I'm thinking of getting the mini 2 fly-more package, then ordering a spare Mini 1 battery so I can always have one battery that is topped off. I can keep the mini 2 batteries at 50% so as not to damage them, and if I need to get in the air unexpectedly I can use the lithium-ion while I'm topping off the 3 lithium polymer batteries.
Fast forward 14 months (7/22). I just bought a Mini 2 Fly More. One battery shipped in the drone, the other two in the charging hub. I've read that DJI was working on this "problem", but yet... So I charged all 3 batts, removed them from the hub and I see no discharge after three days. All indicate fully charged. I don't know what to believe.
What do I do with the brand new batteries Im not going to use for winter right out of the package for the fly more combo.? Can I do nothing till Im ready to use them?
I’m not sure if DJI have issued a firmware update for the batteries yet, but I’m not going to rely on their say so.
I tried storing the batteries in my 3-way charging hub with a thick rubber band around the top of the battery but the electrical contacts inside the hub were biting in to the rubber band so I ditched that idea.
Instead, I cut up a plastic eraser into smaller pieces about 18mm thick (I’m sure a thinner piece would work fine too) and dropped them into the bottom of the battery slots in the charging hub, to prevent 100% insertion of the batteries into the hub, while still achieving good storage efficiency in the Fly More Combo carry bag.
I don’t want to take any chances with the batteries that might shorten their life.
Now to find somewhere in Australia to actually fly the damn drone without having to apply for a permit many days in advance…
I don’t encourage law-breaking but the restrictions here seem to encourage flyers to just send the drone up when there’s no one around, fly around without bothering other people, then pack up and get out of there before a park ranger shows up. Rather than applying for a permit, wait for a week or more for a response, and maybe get rejected any way. I’m all for complying with the rules from the air space regulator (CASA in Australia), but all the parks seem to require a permit which is a pain in the ar$e.
I'm just bought Mini 2 single. But as experienced enthusiastic RC Hobbyist, I always charged my battery about 2-3 bars and pulled out & put it outside from the drone as I treated the drone as my other rc, especially common rc LiPO battery. Never experienced a fire but already had swelling lipo experienced. Though I did not stored them on LiPO safety pack or other unflameable storage box tho. Haha
Hey Rick what kind of battery's are in the DJI Air 2S ??
Lithium Polymer. They have a switch on the battery as he noted. They will auto discharge. Hope this helps.
Thanks for the info Rick, waiting on the mini 2 combo to arrive.
Gary, thanks for the post and you're going to love that quad! I've said from the beginning that the amount of tech DJI was able to cram into that tiny air frame is unbelievable. It really does fly just like the larger quads and can almost fit into your pocket. Have fun and be sure to subscribe to the channel as I have a lot more content posting this week. RIck
Thank you for sharing information about battery. I just bought my first drone mini 2 (2nd hand) and did all the firmware updates on both the mini 2 and the controller. Do you know if it is safe now to store the three batteries in its battery hub? Thanks again.
Great videos. Really helps me to understand. Is the battery in the controller the same way? Can I leave it fully charged or half way during storage?
How do you use the charging Hub to charge your phone/tablet. I plugged mine in and it's not charging my phone's.
Thanks for the question and you can hold down the button on the side when charging to activate the USB-A port. I hope that helps and happy flying!
Great idea sir..thnk you
What a lot of blablabla without solving the issue

I can do the battery out of my 3 pocket storage, but I canot turn them around and and reinsert. My DJI Mini 2 storage has a moulded guide runner that fits each battery and does not allow the battery to seat to the bottom, only half way in. So I will try small block of fire proof stuff inside a metal contatner.
Great video so thank you for that. In my own test in the last few weeks as to how the Mini 2 batteries currently behave outside of the unit, it would appear that they go through two phases of auto discharge, first after 24 hours or so down from a full 100% to 96%, but instead of discharging further at around 5 days, it seems to take that bit longer and around day 6-7 is when the 2nd discharge phase begins which sees the charge drop eventually to 72% over a 24 hour, so the manual stating that by day 5 it should have dropped to low 70s is misleading. I did get notification of firmware updates for my batteries last week and then left them in the hub for 3 days but they stayed at 100% so it looks like DJI to date haven't pushed out a firmware to facilitate auto discharge when they are connected. That said I'm not too bothered and happy to keep the batteries unconnected to anything when storing them
So how long would it take the MA2 battery to discharge after not using after a couple days? I charge them the night before I use them. Thanks Rick for the information.
So how do you wake up a hibernating DJI battery? Do I leave it charging in the hub or drone to wake it up ? When placed in both 3-4 lights just blink and it does not seem to be charging.
So can you allow them to auto discharge out of the charging hub then after 4 days of non use put them back In the charging hub the correct way round?
I'm assuming they will stay discharged at around 75%??
Now when I've driven my battery into the ground & it won't charge anymore...
Does DIJ have a recycling program?
If not, off to the Lowes battery recycle bin...?
Excellent video. The only complaint is that the batteries for the M2 are not the same shape at the top and bottom and you need to use force to insert them into the HUB the other way around. The batteries even have small grooves on the bottom, and the HUB and the drone have corresponding protrusions, so that they are not placed upside down. Thank You!
Great idea about turning batteries around in the charging case, but the Mini 1 batteries won't fit in backwards. Excellent video.
Hi sir rick Is it ok not to remove the battery from the drone if your not using it?
Great tips and information , especially for a flyer like me. So will it be a practical practice like i store them in safety %, the night before I am going to fly i charge them in the hub (likely overnight), unplug them after wake up and go to fly?
Hi, great video. Let me know what is attached to the front legs of your Mini 2?
hI I just recieved my dji battery hub -will the hub charge simultaneously?
If your leave the batteries on the 6 way white charger unplugged the 4 batteries will auto discharge as normal. You can also discharge the batteries it appears with the 6 way charge if you plug them in with it disconnected but have to test further. It appears the pins must be pushed in for the batteries to auto discharge now...
So its definitely not a good idea to fully charge the batterys day before a flight mission?
Many thanks. Excellent advice to a newcomer like me. I've just subscribed. Cheers.
my 3 batteries - all charged in the same charging hub - seem to not be working. They were showing as fully charged. I put them into my drone and they showed as having 96% charge but they simultaneously said 00'00" flight time remaining. One battery wouldn't even get the drone off the ground "unable to take off" and another one forced the drone to emergency land even though it had 48% battery left.
My first thought was that I had put too much voltage through them when charging but now after watching this video I'm less sure. Any ideas would be much appreciated. Thanks team!
Amazing info, your channel should have way more subscribers, Count me as a new one.
Your speech/content speed is very much appreciated , we all come here for info and you my good sir deliver with stellar details and easy to understand. Thank you very much! 👍
Thanks for the support and I love flying and talking about the tech. This is a great hobby and anything I can do to help other fliers enjoy it a little more is time well spent for me. I appreciate your post and be sure to sub the channel so you don't miss anything I'll be sharing this week. Rick
You do a amazing job at explaining how it works good job🙂
Hey everyone
I just bought a dji mini 2
But i have problem with the battery it flashing all the 4 led light and is not turning on.
Any suggestions?
Is a brand new drone.
Thank you for the information
All ways good information rick hope ur doing well ✌️👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Great to see you stopping by and thanks for the post! I hope you're getting in some great flying with the warmer weather. Rick
Hi, if you store the DJI mini 2 batteries out of the drone and either in the pouch or backwards in the hub, as you recomended and let the batts discharge, say down to 40-50%, or maybe less, can you then charge the batteries up to 90-100% just before you fly? Thanks!
Yes, that will work fine. The key thing is not storing the cells at full charge for long periods of time. The latest firmware from DJI for the Mini 2 includes a self-discharge feature to automatically lower the charge after a few days to protect the cells. Be sure to download this firmware to help protect the cells. Thanks for the post! Rick
I don’t understand much of the technical stuff you said but what I got from this is the main part don’t leave your battery’s in charger or drone thanks
They are extremely tight putting in backwards. I'm not trying to damage the Batts. How did yours slide in so easy??
I had them in and out a few times and they made the slots a little larger. You won't have to do this anymore since DJI fixed the issue. You can simply update the firmware and they will discharge normally. Thanks for the post and I hope that helps. Rick
@@Dronevalley, you might want to pin this comment. I just bought my Mini 2, and it's good to know that the firmware update fixed the battery issue. For a first time user the battery issue sounded confusing, though you made a clear attempt to explain it. Thanks.
So has Dji fixed the issue 2 years later?
have 2 batteries. one was stored in drone, everything fine. one was stored alone without any contacts. its faulty now after one year storing. 4 flashing LED issue.
Thank you~very helpful whew [i knew it wasn't just me'!!
There are people modifying their batteries to get much more improved flight time for mini 2. Any videos on that?
Did DJI release a fix already? I recently bought the mini 2 and am flying it almost evey day so I cant leave the batteries for 3-5 days to see if they will auto discharge :D
Hi Rick. My question is if I fully charge my batteries and have a plan to fly in 2 or 3 days, should I keep them in hub or out of hub?
Thanks for the post and honestly the best plan would be to charge them the night before so they are fresh the next day for flying. If you have to charge them a few days early because you're traveling, you should store them in the hub so the "brains" in there can monitor the batteries and discharge them after 3 days in case you don't get a chance to fly. I hope that helps and consider subscribing to the channel as I'll have a ton of content posting this week. Rick
Can you review the Holy Stone H700E GPS Brushless Drone?
If I plan to fly the next day or two, can I charge them up to 100% and how low will they go everyday if left to auto discharge
out of 3 batteries, 2 were fully charged but the 3rd was initially charging but somehow it went cranky with only one light blinking. How do I rectify it? Many thanks
Thanks for the great info. Does the most current firmware fix this issue or are we still waiting for an update?
Time to FLY!!! Thanks for the information!
Dennis, I couldn't have said it better. Get out there and enjoy this great weather. I always say that the best way of discharging your batteries is by flying them! Rick
Anything about the Mini 3 Pro?
Good job, Rick.
If you have a drone with go4 app. And a drone with go fly app. Can they have the same log in.
One of the connections in my mini 2 battery is misaligned and now I can’t charge or discharge. Is there a way to fix this?
Thank you very much for this info I just fly safe and follow the rules just like to video me and wife’s memories thanks so much just a recreational flyer😎🇺🇸👍 those battery’s are not cheap glad I know how to make them last now new subscriber here
One of my mavic mini batteries went into hibernation mode, but I always use it so it never discharges to 0 and isn’t permanently on 100, I also use it as a battery pack to charge my phone. Any idea why it’s in hibernation?
I have a battery when I put it in the charger the third light is flashing and it looks like it’s not charging?
Same issue mine is. 2nd and 3rd is flashing rest 1 and 4th aren't
I charged it into my drone and it fixed my problem. thanks for the info!
Hi, rick you recommended storing the Mini 2 batteries at 40-65%, but DJI says to store them at 72%
What's going on there? Are you right, and DJI wrong?
Anyway, great video, and happy flying!
Jackie, I know this can be confusing but if you check the manual DJI actually recommends discharging the batteries to 30% for long-term storage and transport. If you're going to be using the batteries within a few days, I always recommend the 40%-65% level since it takes less time to fully charge them when you want to fly and still keeps them in a safe state. There isn't a "hard and fast" rule for this and the debate is an active one between pilots. The only hard advice I can give you is never, never leave them fully charged for any length of time and never let them dip below the 10% hibernation threshold. Both of those will terribly stress the chemistry and reduce the longevity of the batteries. I hope that helps! Rick
@@Dronevalley Yeah Rick, I understand you, and thanks for the response. The thing that I don't understand is that in the manual it says if you want to store the batteries "If the battery is lower than 72%, charge it until 72%".
Anyway, I usually store them at 72%, now I will start to store them at around 50%.
Thanks for the help, Rick!
The low point is absolute % for the battery itself. The % reading in the app includes a reserve. 1% in the app is not 1% for the cells, more like 10%. I suspect the AC power off threshold is not even near the cell 0%.
Yeah this is one of the issues keeping weight under 250g and Mini. Add a switch and you just added weight plus increased the size. I'm sure DJI is working on it but I doubt it can be fixed with firmware. Being in a "connected" state without a physical switch it would most likely take hardware to fix. Probably something addressed in the next model.
I think there are some SDR type circuits in the Mini 2 but I'm not sure exactly. But even a SDR has limitations. If they had anticipated this a transistor should do the trick. Controlled by the battery and disconnected after 24 hrs to allow the auto discharge circuit to take over. But then again to engage it one would have to unseat the battery connection and reconnect it to disable the feature and fly.
I think the simplest thing is to store the battery "disconnected ". Even if you just charged them take them out of the charger! Let the clock start! Not sure if it starts after a full charge or from a full "disconnect". Either way just "disconnect" them. Requires a little more work but it's worth it!
I saw someone that used para-cord wrapped around the batteries that blocked contact with the charging hub which would allow you still store them in the hub but allow them to discharge like they are designed to.
Patrick, thanks for the post and the suggestion. I've had a few friends use a large rubber band to do the same thing and they both work. I just flip mine around in the hub and it's been working fine for me. I'm sure DJi is hard at work on a firmware update for this so stay tuned! Rick
@@Dronevalley well, they are not designed to be flipped around, there is a guideline on one of the sides, i personally don’t wanne force them in the smart case. But thanks for the tips.
@@AngelusHD Thanks for the post and it is a little tight at first but works OK. You can always use a rubber band on the top to keep them sliding all the way in. The best option is to use a triple Lipo safety bag to keep them safe for discharge.
Great video, mate. Are the Li-Po batteries for the Mini 2 able to get firmware updates like the drone and the controller?
Great explanation, you did great.
Good reccomendation I have a use for the ammo box I have now
Wow this explains more. Good job
Glad it was helpful! I appreciate the post and hope you'll stop back for more content this week. Rick
Hi Rick. Love your channel because it is so informative. Question: Could you confirm that it is inadvisable to use the Mini original batteries on the Mini 2 ?
I am assuming that you cannot due to the batteries having the 2 different technologies. Thanks a ton.
I just bought a fly more kit and only 2 out of the three batteries work. Because they plugged one into the drone and it totally discharged.
Just know if you’re going to buy a new in box mini 2 fly more kit this late since release. You’re only going to get 2 of 3 batteries.
Thanks for the post but all of the batteries shipped with the drones are in their "dormant" state. They have to be woken up with the first charging and you should charge them to 100% before flying. They can sit in this dormant state for years on a shelf in a warehouse and won't lose any of their charge potential. Once you wake them up with the first charge, you'll need to always keep them above 15% when you're not flying or they may actually drop to zero and can't be revived. If you've tried to charge a new battery and it's not taking a charge, contact DJI and they will replace it for you. I hope that helps, Rick
