Billy, I just want to give you a pat on the back. I watch a lot of drone videos and other videos, and honestly, I think you are one of the better speakers and presenters on them. Dude, you're a natural for this stuff. I've been a musician all of my life, and it's only in the last 4 or 5 years that I feel I've really made an improvement in my speech on stage. You've got a clear and concise voice and plenty of enthusiasm, and, something very important also. You always seem to have done your homework. You always seem to be prepared for your presentations, and in this case, even using notes on your iPad. Good job...., young man, and keep up the good work. Marc T.
Billy, first off, another good, informative video. The last three days, I've spent the better parts of the day watching and researching batteries on the net. The main thing I've seen, that concerns me is the very real possibility of on of them failing, or basically exploding. It could definitely burn down your house, or also fill the house with toxic fumes, but I will say that most of those fires I watched were with the other kinds of lipo batteries that are NOT DJI. I did see one video where a guy tried putting a DJI bat in a drone and it started to smoke so he pulled it out right away. The last thing I want to do here is scare everybody to death and make everybody fearful, but at the same time, it's something to be aware of and possibly deal with. Of all the vids I've watched, the ammo cans or bat safe containers, seem to be your best bet, but make sure to at least, take out the gasket or part of it so if it doesent blow, and there's a place for the smoke and some flames or sparks to escape. They also recommend you can drill some holes in the can instead. The other part of this is to keep either container on a safe surface and maybe 3 or 4 feet away from any flammable stuff like maybe a metal table in your garage or something. Other than this failure possibility, everything you said here seems to be right on. Thanks again, for a very informative video. Marc T.
Have you seen the videos on how to relieve the gas causing the swelling. They just pin prick the silver foil and they deflate and will continue to function and your drone will show remaining charge so no need to worry about using de-gassed batteries.
Even though I don't have a DJI. I do take the seriousness of caring for LIPO batteries. I have the Evo and appreciate that you went over all the safety issues. It just reminded to charge up my old Holy Stone drone batteries that I haven't used for 5 months now. Thanks.
Hey Billy, I agree that using drone batteries as phone chargers makes no sense, but there have been times when I charged my zoom batteries to 100% in anticipation of a flight and then something came up making the flight impossible, so rather than storing a fully charged battery, I used the little DJI "turn your battery into a charger" gizmo to plug into something like a phone or iPad just to discharge the battery down to 50% before storing it. What are your thoughts on that?
Is it safe to always keep a battery in my Mavic Air 2 while left in storage bag/case or does this drain the battery if not planning to fly for a while?
I have an Evo 1...but I'm assuming all these smart batteries are similar. My question is: If I store my batteries at 25-40% charge for an extended time... do they stay at that charge? Or will I need to charge them up to 40% again every few weeks/months? And if so, do I only charge them back to 40% or all the way back to 100%?
If I fly my drone every few days/weeks should I charge my battery after flying and leave it with full charge or should i just charge it shortly before flying?
right on Billy, thank you for another awesome badass episode, I can already say I took a few tips off of this video and I'm definitely going to apply these thanks again Buddy, greets from California 🤙✌
Read. I have been flying fpv drones for years now. I own alot of lipo batteries. #1 tip is the battery should always be in storage charge, 3.8v per cell. You should charge before you fly, come home and storage charge all your batteries. My rule is 24hours max at full charge. Dji doesnt allow this, their batteries are proprietary and expensive so they are happy to see em puff. Lets make a storage charger/discharger for dji batteries. Alll my lipo rc chargers do this and balance the cells every time. I can adjust current rate etc. Lipos should be charged at a 1c rate. 1300mah = 1.3a. I always flew my batteries from 4.2v-3.5v per cell. Then back to 3.8 for storage. Lipo hv is a little different. Lipo-hv max voltage is 4.35v and storage is 3.8v. All my rc chargers only store @ 3.8v. But I hear 3.7-3.8 I never had a lipo-hv battery drop out of the air at a higher voltage than all my lipos. At 3.3v lipos and lipo-hv will start dropping fast. "We only need an adapter to go from dji battery to balance connecter and a +- for all cells." Should be easy.
Good video, many people don’t understand Lipo care. The worst tip/myth I see online is to drain lipo batteries down as much as possible - huge mistake with lipos!
Billy Kyle in all seriousness pretty worried about my parents in NJ. Tri state area is a mess. Glad I’m not living there right now since I’m in mid America where this hasn’t hit hard yet but at the same time... stay safe man.
Hi this is a very helpful video you have shared for dji drone users. I was looking for is that after the batteries have discharged to 20% or so, do we remove them from the charging hub and store it away, specially if we don't use the drone for months. I only use drone when i go on vacation in six months or a year so dont use the drone regularly. If you can answer this would be helpful and appreciate this.
Mavic Mini uses Lithium Ion (vs the Li-Po batteries on the other drones), so they don’t need to auto-discharge. One advantage of the Li-Ion batteries is that hold their charge much longer when not in use.
Hi Billy, Need help with a question about my DJI Mavic Pro batteries...I bought 2 extras, used all 3 in CA for about a year w/ not a lot of use (12 hours total between all 3), stored them for about a year, and then moved to FL. Now that I'm in FL, I tried charging my 3 DJI batteries on my DJI charging hub. 1 battery blinked 25% green and appeared to be charging, the other 2 batteries lights didn't come on at all. I charged all 3 on the hub for about 10 hours. Each battery will not come on once placed in my drone. Do I need 3 new batteries? Or is there a way to charge these batteries? Please advise. I'd hate to pay another $150 each X 3 for new batteries if I don't have too. And, in your next battery video would you please address battery troubleshooting? Thank you for your help. Cindy
I dont know if I missed the explanation of how 2, 3 and 4 are swollen but what did you do wrong for 2, 3 and 4 to swell? I know you mentioned how they pop out when being placed into the drone even with force and how the bottom shows the swelling on battery 3 compared to battery 5.
The only drone I've have is the mavic pro. All though I don't get enough time to fly it the 3 battery's are doing well for a 4 years old drone. Do you still fly your mavic pro drone any more.
Do you have any tips for people with Mavic Airs since the battery got discontinued? I’m pretty shocked that my drone may effectively be useless even through it flies perfectly well since I can’t find any new batteries. Makes me nervous to invest in DJI again
Dji Marvic Air, my first drone! and i don't keep my batteries well then it swollen and i never use that swollen anymore! Question: After that those batteries (swollen) never use for long time now it come to normal it flat not swollen anymore, is it useable?
Hi Billy and thanks for all you working. The battery Dji Mavic 2 and Dji Mavic 2 Enterprise are the same battery. I have both Zoom and Enterprise and batteries are identical.
This must be in radio control application and the drone that all changes.
Hi! I just recently bought my new DJI Air 2s. As for my batteries, I'm just curious why my battery is only at 4.10v something when fully charged and also the rest of my batteries, isn't it supposed to be at 4.20v because it's still new? And I only have 2 cycles.
I know you asked this a couple months ago but if I had to guess he probably ran the batteries way down after flying and instead of letting them cool down sufficiently he went ahead and started charging them which created an abundant amount of heat. Several years ago I did this in an RC helicopter and not only did the LiPo swell a lot but it got so hot it turned the outer plastic wrapping brown with little bubbles. Luckily I was home and smelled the burning.
What about the battery in the controller? I just noticed the max charge I can get into the controller is 97%. Should I "cycle" the battery, meaning, should I leave it turned on, linked the the drone, and let it drain down some, then re-charge?
just sharing my experience....!!! I've been using 3 DJI battery's for already 2 years and they have already 170 and up cycles but none of them ever got boated or anything same flight time and same as new physically....all i do is that when i charge this 3 battery's i must use them within 24 hours then when i store them i usually have 20% left...i also set my discharge time to 3 days....also i never left a fully charge battery unused for more than 2 days....that my strict rule i set myself. >__< ...but its worth it :D...never change my battery since :)
@@thelonehellyranger01 you can't on mavic air so you probably can't on most drones that came out before it. Just turn your drone on and run it to 2dots after use. I usually fly my drone and bring it back 20%-30% then don't charge it if I don't need to. So this discharge function isn't actually needed as much in real-world scenarios as you would think. If you charged up 3 before the day and use 2 then you would only need to discharge 1.
I just bought the mini 2 (first real drone) and only got one battery. I tend to unplug the battery from the drone when storing them to practice good battery care. Am i doing the right thing or is it better for the self discharge thing to be plugged in the drone?
Great video Billy. You should also do one on charging the various controllers. I know they don't discharged as quickly as the batteries, but i think it would be good to know the proper way to care for the controller and when to charge it. Take care and stay safe.
I agree. I normally wait until it's around 20 some percent and then charge it all the way up, and sometimes it will sit charged for a couple weeks or more.
Thank you for making the video I noticed the other day that my battery will pop back out on my Mavic pro two I just now looked and I have three batteries that are swollen I almost lost my drone thanks for the video thank you for making my video
Which DJI GO app is being referred to? Sorry, I'm new to all this and I've got the MA2 and using the DJI FLY app. When I search for the GO app I'm seeing the GO app before P4 & the GO 4 app. Thx
Hi Billie, thanks for the tips! My drone has been idling for 2 months now since the lockdown, n yeah, was quite worried for the batteries. Glad to come across ur vid! Thanks once again! Just subscribed to ur channel & looking forward to watch ur videos!
I liked your tip on how to tell if a battery has swollen. I will check all my battery’s and make sure they set flat on a table. If any of them rock when I push down with my finger on top of them, they will properly be disposed of and replaced. Thank-You for the Info!
My mavic pro battery I've had discharge to 30% but I recharged them as I monitor them occasionally. Mine are set to 10 days. Also my remote discharges slowly too...
I have an official, unswollen battery that seems to be "always on" so that when I put it in the drone, it instantly turns on and I am unable to turn the battery off. So I let it drain all the way down while in the drone, but now the battery wont light up at all, when plugged into the charger... is it toast?
Good info. But an FYI all of my Mavic Air batteries have some front to back wobble, but it's because the "feet" numbs on the bottom of the battery are shorter on the terminal side than the other end. So it's important to pick the battery up, turn it over and look at the seams of the printer area as you hold it eye level the seams should make parallel lines as you tilt and then return to flat at eye level. If there is a bulge you will see the lines not come together but you will see the arch of the bulge. Harder to explain than to just do my test.
I was more worried about my own errors of maintenance. This video gave me a little confidence that I’ve been doing some of the right things. If I got all my batteries at the same time how do I label them? That’s where I’m falling short
I’m wondering how to maintain them if you don’t use them for like a year. I bought mine for traveling but haven’t flown it in all at a year. I buddy of mine said his battery died completely because he didn’t charge it over a year. So.. should I charge them every few months? And let it die down naturally in the settings? Any advice?
I would definetly open those puffed batteries, find the size of cells they used ie 18650 and replace the cells. Leave them in storage charge if you want em to last.
If you watch the video properly, your question already got the answers perfectly ! Let me recap again, sigh ! Store your battery at 40-60 percent capacity at around 25-28 Celcius temperature (normal room temperature), keep it away from direct sunlight, any liquid and dust ! You understand now ?
Billy, at the risk of asking a stupid question when it comes to putting a M2P away for a few months what would be preferable, to fold it up box it & leave on a shelf or leave it on the shelf unfolded and with battery in place or removed? Thanks upfront, getting 'schooled' by someone who has decades on me is sobering but thankful none the less.
Hello sir Good evening actually we don't need to charge our device through our controller while when we are in flying mode sir, please guide us how to stop it sir. the option I saw in mavic pro but we are using mavic 2 pro is there any option to turn it off sir please help us sir
I know this sounds crazy but i baught a mavic air in 2019 and havnt had a chance to fly... i got busy with work, had a baby and went into lockdowns!. Are my batteries screwed? I have never even charged them once... the drone and batteries have never been used. Is it safe to use?
Great tips. I got a Mavic 2 Pro in December and love it. I fly in Japan. I’ve been very careful with the batteries. I try to treat them as carefully as I would treat the quad itself. I heard an interesting tip was not to watch the battery percentage, but rather pay attention to the voltage of each cell. The reason being that percentage is not an accurate reading of the performance of the battery. It can suddenly go down depending on the conditions. By looking at the voltage you’ll get a more accurate reading of the health of the battery while in flight and its energy needs. With that in mind, it’s suggested that you never let the cells go below 3.6 volts. This prevents the battery from overwork and helps extend the life of the cells. Doing this from my own experience, I end up consistently ending my flight at around 25-20% and with an average of of 23-minutes of flight time. FYI: I just rotate two batteries.
Is it safe to have the battery sitting fully charged? sometimes I may charge to go fly and the weather gets bad, so I end up not flying, so it goes into auto discharge after 5 days but I noticed they are warm. I don’t want it to become a 🔥 fire hazard in my home. Please clarify if you can.
Thanks for sharing this useful tip and I have another question ‘Should we recharge our battery after using or should recharge before flight?’. I am asking this question cos some people said ‘Don’t recharge your battery and keep it’
Very helpful information as usual. Don't know if you mentioned this in the video.... How did your three batteries become swollen? Too old, often used....?
Great video as usual, my question is in the app the charge count that you see. Is there a discharge % that the battery needs to drop to or any time you charge to 100% will that count go up by one count.
Hi, I'm interested to know your thoughts on DJI batteries. I think the flight battery is the weak point with any DJI drone, as Lipos have a short lifespan and when DJI stop producing them, which I believe they have for the Mavic Pro, the drone essentially becomes unusable. Do you know if there are any third party batteries which will work reliably? Thanks
Hay Billy another great vid, just a question about the batteries, does all this info count towards the Mavic mini batteries as they are lithium ion as apposed to lithium polymer? Just curious as I am a mini flyer. Cheers keep the excellent vids and stay safe.
From what I read, Mavic Mini batteries are less intelligent (even though they cost $45??), and do not discharge themselves. You need to manually do that.
Great information, 2 of my 3 batteries are swelling in my M2 but still produce normal voltage signs in all 4 cells & still give long flight times. I’ll definitely be replacing them soon , thanks.
One of my batteries for the mavic air 2, after a short flight, I tried to turn the batt off it would not turn off after numerous attempts. I pulled the batt out of the drone tried again to turn it off, nothing. So I placed the batt back in the drone it still had 3lights on . The drone hovered at the 4ft height for 30 seconds and fell to the ground breaking the gimbal. Has anyone had this problem and what recourse do I have. The drone is only 4 months old. This is the second time this has happened. The first time I had a hard time turning it off,but eventually it shut down. I charged straight from the brick ,flew it with no problems. Each time there were 3 lights on the batt.
Thanks Billy. You are my go to guy and your videos are to the point and just great. Question you did not address. What made you batteries swell up like that? Why do batteries get swollen?
Thank you! I have heard that around the time I bought my batteries DJI was having some apparent manufacturing issues. A lot of people also report their batteries have swollen when comparing similar purchase dates.
I just tried my first attempts flying the DJI Mavic Mini. (got fly more pack, so 3 batteries) After 20 min of flight everything ok...nr 1 battery still 40%. BUT...problem ...Iphone battery already drained from 100%full down to 35% and phone feels quiet warm. Any sugestions ?
Hi Billy, hey i'm waiting on my Mavic Air 2 to arrive Wednesday but i"m still unsure, when i put first battery in and do the first update on the Air 2, then do i put each battery in and do update again?
lel - My Mavic 1 Pro still operates all 3 batteries that came with the "Fly More Combo". 80 loading cyles everage. 20 mins. no problem, and land them at 20%. And if you don't know when you'll fly your drone again, charge all of them to full, and set each to 1 day auto-discharge.
after only using my drone 3 times in 3 years one of my 3 batterys discharged fully and now I dont know how to get it back. If anyone has a tip or anything to say to this please do so. I know know how to treat them other 2 batterys properly but my other third is still not useable anymore even if I never used it before lol
I have so much fun watching your videos from day one on youtube; Because you make some really good points and miss alot of the more important ones; I live only doing battery maintanance flight and live broadcasting doing shout outs to you on face book; you and ken Heron; man are you missing alot of pionts on this video big time and all i know i learned on facebook i guess?
point #1 always screen shot battery page before take off; nobody does this! Then if possible mid flight; and one screan shot before landing and another after landing ; super inportant;
Very thorough video Billy. What is DJI's stance on the swelling battery issue ?? I read on a forum that in Aug-Sep 2018 a bad batch of batteries got out. If so maybe replacements will be provided.
Does anyone out there now if you can still today by Genuine DJI batteries for the original Mavic pro? Wondering what people do if the manufacture stops making the battery and your drone is still able to fly?
I have 2 swollen batteries. I've been using them as battery banks. At full charge they charge my phone quite a few tomes. You think that's a bad idea? Great vids by the way!!
@@billykyle you may have misunderstood. I ONLY use the swollen batteries as power banks, not to fly. Was just wondering if you heard of that being a bad idea? Mahalo
Same here. Using a couple of my Mavic Air batteries only as power banks ever since they started to swell. I figure it is safer since they don't heat up as much compared to when using them on the actual drone. But always a risk the more they swell.

So this discharge function isn't actually needed as much in real-world scenarios as you would think. If you charged up 3 before the day and use 2 then you would only need to discharge 1.
I just bought the mini 2 (first real drone) and only got one battery. I tend to unplug the battery from the drone when storing them to practice good battery care. Am i doing the right thing or is it better for the self discharge thing to be plugged in the drone?
Great video Billy. You should also do one on charging the various controllers. I know they don't discharged as quickly as the batteries, but i think it would be good to know the proper way to care for the controller and when to charge it. Take care and stay safe.
I agree. I normally wait until it's around 20 some percent and then charge it all the way up, and sometimes it will sit charged for a couple weeks or more.
Use the feature to charge up your half dead phone to discharge it down to 30%
This whole video could have been 3 minutes
Thank you for making the video I noticed the other day that my battery will pop back out on my Mavic pro two I just now looked and I have three batteries that are swollen I almost lost my drone thanks for the video thank you for making my video
Which DJI GO app is being referred to? Sorry, I'm new to all this and I've got the MA2 and using the DJI FLY app. When I search for the GO app I'm seeing the GO app before P4 & the GO 4 app. Thx
Does intelligent flight battery mean Dji can prevent any number of cells from charging and turn off overcharge protection?
Hi Billie, thanks for the tips! My drone has been idling for 2 months now since the lockdown, n yeah, was quite worried for the batteries. Glad to come across ur vid! Thanks once again! Just subscribed to ur channel & looking forward to watch ur videos!
Same here with flying in the UK the weather is not good ATM
How about the mavic mini? Its not a lipo batt. How many percent of the battery should you prefer for storage?
I liked your tip on how to tell if a battery has swollen.
I will check all my battery’s and make sure they set flat on a table.
If any of them rock when I push down with my finger on top of them, they will properly be disposed of and replaced.
Thank-You for the Info!
No worries! Glad I could help👍🏻
My mavic pro battery I've had discharge to 30% but I recharged them as I monitor them occasionally. Mine are set to 10 days. Also my remote discharges slowly too...
A buddy of mine made a suitcase which keeps my drone batteries warm (between 20 and 30 degrees) when its freezing outside. Its great.
What about cycling the battery? What about battery discharge procedure?
I have an official, unswollen battery that seems to be "always on" so that when I put it in the drone, it instantly turns on and I am unable to turn the battery off. So I let it drain all the way down while in the drone, but now the battery wont light up at all, when plugged into the charger... is it toast?
Good info. But an FYI all of my Mavic Air batteries have some front to back wobble, but it's because the "feet" numbs on the bottom of the battery are shorter on the terminal side than the other end. So it's important to pick the battery up, turn it over and look at the seams of the printer area as you hold it eye level the seams should make parallel lines as you tilt and then return to flat at eye level. If there is a bulge you will see the lines not come together but you will see the arch of the bulge. Harder to explain than to just do my test.
What is better: Storing the battery inside the drone or keeping it outside?
Hey Billy, one of my Phantom 4 batteries was in storage and won’t charge up. Is there anyway to recover that battery or is it dead forever?
I was more worried about my own errors of maintenance. This video gave me a little confidence that I’ve been doing some of the right things. If I got all my batteries at the same time how do I label them? That’s where I’m falling short
I’m wondering how to maintain them if you don’t use them for like a year. I bought mine for traveling but haven’t flown it in all at a year. I buddy of mine said his battery died completely because he didn’t charge it over a year. So.. should I charge them every few months? And let it die down naturally in the settings? Any advice?
Not something I would normally think about. Thanks to you and ReadySetDrone for battery tip videos👍
I would definetly open those puffed batteries, find the size of cells they used ie 18650 and replace the cells. Leave them in storage charge if you want em to last.
What do you recommend I do for long term storage? Say 6 months without use? Should the be Slightly charged during this time?...thanks!
If you watch the video properly, your question already got the answers perfectly !
Let me recap again, sigh ! Store your battery at 40-60 percent capacity at around 25-28 Celcius temperature (normal room temperature), keep it away from direct sunlight, any liquid and dust ! You understand now ?
@@cenningitis2910 thanks for the clarification d-bag 👍
Billy, at the risk of asking a stupid question when it comes to putting a M2P away for a few months what would be preferable, to fold it up box it & leave on a shelf or leave it on the shelf unfolded and with battery in place or removed? Thanks upfront, getting 'schooled' by someone who has decades on me is sobering but thankful none the less.
Thanks Bill. Your channel Is the best
Hello sir Good evening actually we don't need to charge our device through our controller while when we are in flying mode sir, please guide us how to stop it sir. the option I saw in mavic pro but we are using mavic 2 pro is there any option to turn it off sir please help us sir
Auto discharging only works for the battery that is in the drone. Correct?
Wrong
some of my batteries swells only after flying or when heat. i labelled them so i can cycle its usage. helpful video.
Labeling is key👌🏻
Hi Billy ! Excellent job on battery care, I having a hard time finding a battery for my Eachine . Where is the best place to buy one or two ?
I know this sounds crazy but i baught a mavic air in 2019 and havnt had a chance to fly... i got busy with work, had a baby and went into lockdowns!. Are my batteries screwed? I have never even charged them once... the drone and batteries have never been used. Is it safe to use?
Ideal storage for LiPo cells is about 3.8volts per cell. How do we do this with DJI batteries?
Great tips. I got a Mavic 2 Pro in December and love it. I fly in Japan. I’ve been very careful with the batteries. I try to treat them as carefully as I would treat the quad itself.
I heard an interesting tip was not to watch the battery percentage, but rather pay attention to the voltage of each cell. The reason being that percentage is not an accurate reading of the performance of the battery. It can suddenly go down depending on the conditions. By looking at the voltage you’ll get a more accurate reading of the health of the battery while in flight and its energy needs. With that in mind, it’s suggested that you never let the cells go below 3.6 volts. This prevents the battery from overwork and helps extend the life of the cells. Doing this from my own experience, I end up consistently ending my flight at around 25-20% and with an average of of 23-minutes of flight time. FYI: I just rotate two batteries.
Is it safe to have the battery sitting fully charged? sometimes I may charge to go fly and the weather gets bad, so I end up not flying, so it goes into auto discharge after 5 days but I noticed they are warm. I don’t want it to become a 🔥 fire hazard in my home. Please clarify if you can.
When you transport your drone, is it ok to leave a battery plugged into the drone or always remove the battery?
Thanks for sharing this useful tip and I have another question ‘Should we recharge our battery after using or should recharge before flight?’. I am asking this question cos some people said ‘Don’t recharge your battery and keep it’
Well... for your information under the plastic shell u will find a specific logo (Samsung) if u thought dji did there own cells they don't. 13:50
How do I discharge my Phantom 4 pro battery for travel?
New fan from South Africa, thanks for the great info 👍😀
Very helpful information as usual. Don't know if you mentioned this in the video.... How did your three batteries become swollen? Too old, often used....?
Hi Billy, if i want to store the battery for quite a long time as i bought a new drone should i charge them first to around about 40-50%? Thanks
Great video as usual, my question is in the app the charge count that you see. Is there a discharge % that the battery needs to drop to or any time you charge to 100% will that count go up by one count.
Hi, I'm interested to know your thoughts on DJI batteries. I think the flight battery is the weak point with any DJI drone, as Lipos have a short lifespan and when DJI stop producing them, which I believe they have for the Mavic Pro, the drone essentially becomes unusable. Do you know if there are any third party batteries which will work reliably? Thanks
Hay Billy another great vid, just a question about the batteries, does all this info count towards the Mavic mini batteries as they are lithium ion as apposed to lithium polymer? Just curious as I am a mini flyer.
Cheers keep the excellent vids and stay safe.
Good question
From what I read, Mavic Mini batteries are less intelligent (even though they cost $45??), and do not discharge themselves. You need to manually do that.
Great information, 2 of my 3 batteries are swelling in my M2 but still produce normal voltage signs in all 4 cells & still give long flight times. I’ll definitely be replacing them soon , thanks.
Typical DJI batteries.
One of my batteries for the mavic air 2, after a short flight, I tried to turn the batt off it would not turn off after numerous attempts. I pulled the batt out of the drone tried again to turn it off, nothing. So I placed the batt back in the drone it still had 3lights on . The drone hovered
at the 4ft height for 30 seconds and fell to the ground breaking the gimbal. Has anyone had this problem and what recourse do I have. The drone is only 4 months old. This is the second time this has happened. The first time I had a hard time turning it off,but eventually it shut down. I charged straight from the brick ,flew it with no problems. Each time there were 3 lights on the batt.
I have 3 swollen Air 2s batteries. Thanks for the information. I will take better care of my next batteries.
How many times you have used the battery after it's swollen?
@@bharatdeshbhandari9619 I didn't. I was afraid of damaging my drone.
thank you for tips and sharing. its useful
Is there currently a way to Change the battery settings for the mavic mini? Or can I download the DJI go app and do it through that?
i was advised by dji that batteries needs draining every month, and when left unused for 3 months batteries should be at 50percent upon storage
Thanks Billy. You are my go to guy and your videos are to the point and just great. Question you did not address. What made you batteries swell up like that? Why do batteries get swollen?
Thank you! I have heard that around the time I bought my batteries DJI was having some apparent manufacturing issues. A lot of people also report their batteries have swollen when comparing similar purchase dates.
I just tried my first attempts flying the DJI Mavic Mini. (got fly more pack, so 3 batteries)
After 20 min of flight everything ok...nr 1 battery still 40%.
BUT...problem ...Iphone battery already drained from 100%full down to 35% and phone feels quiet warm.
Any sugestions ?
Hi Billy, hey i'm waiting on my Mavic Air 2 to arrive Wednesday but i"m still unsure, when i put first battery in and do the first update on the Air 2, then do i put each battery in and do update again?
I just I pleaded my battery completely so I suppose to recharge for storage ?
how long can I store them without needing to re-charge, such as during Winter please?
So with my controller at what percentage should I store it?
Is the battery auto discharge feature available for the mavic mini ?
FYI the Mavic 2 pro has been known to have battery swelling issues, if you contact DJI they’ll send you new ones with no issues
lel - My Mavic 1 Pro still operates all 3 batteries that came with the "Fly More Combo". 80 loading cyles everage. 20 mins. no problem, and land them at 20%.
And if you don't know when you'll fly your drone again, charge all of them to full, and set each to 1 day auto-discharge.
This guy is so professional!
I accidentally dropped my battery and it broke one of the pins on the connector. What should I do with it?
The BED HEAD LOL!! A little repetitive but, a lot of good information.
after only using my drone 3 times in 3 years one of my 3 batterys discharged fully and now I dont know how to get it back. If anyone has a tip or anything to say to this please do so. I know know how to treat them other 2 batterys properly but my other third is still not useable anymore even if I never used it before lol
I have so much fun watching your videos from day one on youtube; Because you make some really good points and miss alot of the more important ones; I live only doing battery maintanance flight and live broadcasting doing shout outs to you on face book; you and ken Heron; man are you missing alot of pionts on this video big time and all i know i learned on facebook i guess?
point #1 always screen shot battery page before take off; nobody does this! Then if possible mid flight; and one screan shot before landing and another after landing ; super inportant;
only charge battery as close to take off as possible; you want them fully charged as short of time possible
never consider battery precentage correct; only cell voltage is acceptable ; under 3.7volts in flght is landing now; i do not care if it says 45%
I live doing these battery maintanance flight and could easly put up 100 rules;
Ispire 2 from DJI says 15min flight time and under 3.7volts is landing now;
Can someone explain to me what makes the DJI batteries smart?
Mavic 2 battery storage mode? How many percent should be?
40-50%
I had no idea of battery swelling thank you for this video.
No problem! Glad you were able to take something away from the video👍🏻
@@billykyle is this giveaway a scam?
Very thorough video Billy. What is DJI's stance on the swelling battery issue ?? I read on a forum that in Aug-Sep 2018 a bad batch of batteries got out. If so maybe replacements will be provided.
I'll have to give it a try.
How and where to store batteries when you're not flying?
Does anyone out there now if you can still today by Genuine DJI batteries for the original Mavic pro? Wondering what people do if the manufacture stops making the battery and your drone is still able to fly?
I have 2 swollen batteries. I've been using them as battery banks. At full charge they charge my phone quite a few tomes. You think that's a bad idea? Great vids by the way!!
It's not horrible, but imagine all of the extra use on the batteries charging your phone creates. Less flying time you'll get from that battery.
@@billykyle you may have misunderstood. I ONLY use the swollen batteries as power banks, not to fly. Was just wondering if you heard of that being a bad idea?
Mahalo
Same here. Using a couple of my Mavic Air batteries only as power banks ever since they started to swell. I figure it is safer since they don't heat up as much compared to when using them on the actual drone. But always a risk the more they swell.
