[@davekidd7811]

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

[@stormnnorm69]

Thanks Rick great info 👍

[@Dronevalley]

Norman, thanks for the post and I'm glad you enjoyed the clip. I'll have a few more this weekend so stay tuned. Rick

[@FrogandFlangeVideo]

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.

[@richardkoh2423]

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

[@piee683]

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

[@Dronevalley]

Thanks for the post and it's a tricky answer. If you leave the battery in the Air 2S it will auto-discharge normally so no worries about the charge. Where it gets tricky is that the auto-discharge produces some heat and that's never a good thing for the quad. It's small, but over time it worries me that it might unnecessarily fatigue the quad. The other concern is that if a battery does decide to go non-linear and misbehave, if it's out of the quad, you've only lost a battery. if it's inside the quad you've lost everything. To put this into perspective, I have a ton of quads in the shop and literally a hundred or more Lipo cells. I've been flying for years with a lot of other pilots and have never had, or heard of a Lipo fire with any of them. Its a rare issue, but like with home fires, we have to be careful because of the possibility. I hope that helps and my advice is always to fly more and worry less. Rick

[@jdgtv7549]

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

[@20yearsagotoday1]

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.

[@Dronevalley]

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.

[@elineblind348]

Good one

[@denkn]

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....

[@Dronevalley]

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

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

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.

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

Hello kind sir, I finally got the correct video showing how to charge both battery & controller usung the mini hardware.

[@offimatrix4897]

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.

[@alladventurecapitol]

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.

[@DonaldHerron]

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

[@WW5RM]

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!

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

[@thomassouthard5535]

Lithium Polymer. They have a switch on the battery as he noted. They will auto discharge. Hope this helps.

[@honigtrailapiary4341]

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!

[@Dronevalley]

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

[@PP-rl5sn]

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

[@oscarcampbellhobson]

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?

[@georgealexander2955]

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???

[@Dronevalley]

George, you're going to be fine and it's an incredible machine that you're going to love flying. The only thing you'll need to remember is to never put your batteries away fully charged, especially into the hub. If you have them out of the hub (and drone) they will auto-discharge if needed. My routine is to fly them down to about 30% and put them away. The next time I want to fly I charge them and head out to the lake for some fun. Let me know if you have any other questions and consider subscribing to the channel so you don't miss anything. Rick

[@matterhorn1975]

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%??

[@FlymyPhantom]

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

[@Tahsin_Hussain]

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?

[@michaellaframboise7646]

[@sohelislam7388]

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?

[@Dronevalley]

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

[@TH3_DON_M3G4]

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.

If your leave the batteries on the 6 way white charger unplugged the 4 batteries will auto discharge as normal.

[@MaxFromSydney1]

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.

[@joegallacher8032]

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!

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.

[@synthyawylder3297]

Anything about the Mini 3 Pro?

[@randysmith6493]

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.

[@deks223]

Mine has the line and groove too but with enought force it will go in backwards :D
