Mini 2 Battery Issues and How To Fix Them 

Always great information. You did it again!! Thank you, sir.

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

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.

Rick, I wish you had been my science teacher 50 years ago. Nice job, and I don't even own a drone !

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

Excellent and informative video! Knowing why these batteries do this is incredibly important to many of us. Thanks!

Great explanation!!

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 !!

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 😁

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.

You do a amazing job at explaining how it works good job🙂

Brilliant mate thanks for explaining it 👍

Thanks for the technical background. The idea and solution with the "firebox" is great. Many regards ANTJE und LUTZ

Great explanation, you did great.

Thanks for the great info. Does the most current firmware fix this issue or are we still waiting for an update?

Thank you sir, this is great information.

I admire you so much Rick ,you are BRILLIANT .

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

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?

Thank you for the information

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?

great video thanks for sharing

Thanks for the info Rick, waiting on the mini 2 combo to arrive.

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.

Many thanks. Excellent advice to a newcomer like me. I've just subscribed. Cheers.

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!

Thanks Rick great info 👍

Great video, mate. Are the Li-Po batteries for the Mini 2 able to get firmware updates like the drone and the controller?

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 sharing. DJI has advised me to remove batteries from the Drone or Charging Hub when not in use

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.

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.

Great idea sir..thnk you

Thank you for your information great video

Time to FLY!!! Thanks for the information!

Hi sir rick Is it ok not to remove the battery from the drone if your not using it?

For an owner of the mini 2 for less than a week, this is good for me. Thank you

Thanks for another informative video.

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

All ways good information rick hope ur doing well ✌️👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

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.

Wow this explains more. Good job

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?

Mine havent discharged in 5 days, I hear DJI have admitted there is a fault and will be issueing a firmware update shortly

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....

Thanks Rick saved the day again for me :-)

Great information as always thank you,can I ask so is it perfectly safe to leave the battery in my air2s drone

Thank you for sharing your knowledge. Cheers mate. 🦘🇦🇺

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.

Good job, 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.

What is the firmware ver. Of the mini2 When you had this video? Latest is v1.003 something, did they made corrections on the auto discharge function now?

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, great video. Let me know what is attached to the front legs of your Mini 2?

Thank you sir..

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...?

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

thank you for your valuable information! subs!

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

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.

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

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%??

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!

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.

Think he has more coffee then i do ^^ grate info. i keep my battery in drone when there's only 17% or less left in charge.

Rick the strangest thing happen to me with my FPV. It has been flying beautiful so I decided to try it with the joystick controller. I went into connect it etc and the DJI fly app took me to the fly tutorial and it won’t let me out. I’ve deleted the app, reinstalled it. Turned peer off n on. Any ideas? Also I put a 129 card in goggles and drone. Is there a size limit that you know of. Thanks Ron.

Do you have any guess as to how much more life/time that would provide to your battery?

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!

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

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 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

Good reccomendation I have a use for the ammo box I have now

Can you review the Holy Stone H700E GPS Brushless Drone?

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...

Hey Rick what kind of battery's are in the DJI Air 2S ??

hI I just recieved my dji battery hub -will the hub charge simultaneously?

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.

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?

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!

I recently bought a salt water damaged Mavic mini 2 drone. Then by mistake before cleaning the circuit I connected the battery for a second. Then smoke came out from the drone near the drone legs. I promptly removed the battery. Does not look like any damage to the battery. So put the battery in DJI Mavic 2 battery charging slot and it is showing the battery level and charging too. How can I know that battery is not damaged? Also is it same to insert this battery to another drone?

L P Estrada 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.

I have the original Mavic Pro battery. Any suggestions on an easy way to wake up the battery after it has gone to sleep?

Hey Rick what if I got a brand new mini 2 that I haven't even opened the box yet? Am I going to be in good shape or do I need to do something???

Thx

What kind of batteries are in the controller mini 2 already have had to replace one battery for the Drone

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?

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.

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!

Rick I don't see the lipo bag any where!! I want to order one?

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.

Hey Rick, a side question here. How well do the Yagi Range Extenders really work? I was thinking about getting one for my MM2, are they really worth it?

I'm sold on those battery covers.

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?

Is it helpful to drain mini 2 batterys?

There are people modifying their batteries to get much more improved flight time for mini 2. Any videos on that?

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?

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

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.

Anything about the Mini 3 Pro?
