- Опубликовано: 21 авг 2024
- This is Part 2 in my Mini 2 battery mod series. ALL functions restored and 36:20 flight time with some old cells. I believe this can be improved!! NEW cells are on the way, so I will do additional testing for maximum flight time! :)
ENJOY!

I realize the battery chips make for a complicated replacement or modification, but Man you taken a lot into consideration and saved a lot of people from a headache. Keep up the cool tinkering, you matched many genius levels, and made your work easy for us to understand and learn from. THANKS for all you do, had to drop another comment.
Oh wow! Thank you so much! :) That was one of the nicest acknowledgements I ever got! :) Cheers
@@ZollyD can I use mini 2 batteries, soldier them together for a bigger battery?
I LOVE YOUR WISDOM AND ALSO YOUR VOICE!!!!!
OMG! Thanks a lot! :)
You are a pioneer in this method. But don't be angry with me when I say that it's better to buy a license from Pat and reprogram the BMS. I have great results.
I am not angry. I know how great TRB is. That is why I will do a video on it. But i just love to do the hacking. And why not let people know all the options...😊
Who is Pat?
Great methodology! Look forward to your testing on different cells for optimal results.
Thanks! :) As soon as the cells arrive I will do it. :)
You've got cool stuff on your channel keep going... Dude 👍
Thanks! I will keep them coming! :)
Well done! Would be nice to show or tell how long the flight time is with the stock battery in these same conditions for comparison.
Wish young people see thing like this rather than those stars etc...Kim Kardashian. Very practical and informative content. I wish you can mod the Mini 2 to run on some high end lithium-ion cells like tesla, panasonic.
Thanks! :) I agree, that the next generation should also get some more intellectual stimulation as well. Fine to watch idiotic content, but balance it out. :) Regarding the Mini2 Li-ion cells; that vid will come. I am just waiting for some LiPo cells in the mail now for 3 weeks... The parcel is stuck in customs clearance.... 😴😴😂 when that arrives I will do more testing like in this video, and after that I will move on hacking the Li-ion cells in... ;)
Sensacional vou fazer no meu 🎉🎉
Great video, you explain everything very well. Thank you!
You are welcome! I am happy you liked it.
Alligator clips and a quick disconnect might make your bench testing more less complicated. I was thinking perhaps create a flat connection on the top shell underneath, that connects to the battery module on the pcb rather than the battery itself. It shall piggyback off the BMS, TX/RX. This way you don't have to keep soldering and leaving that battery gate open Aka affecting the aerodynamics
Yeah, that could work too! :)
i can see where watching your videos is going to be very very interesting and you have already answered a question i have long been asking myself, how can we fly longer hhmmm
You got a new student👍🏻thanks
Thanks! I am glad that you find them useful. :)
another level👍,can you do to fimi mini ?
Very good video !!!!!
What cells have you on the way ?
So, just to summarize, if you connect cells in parallel when they are all discharged to the same voltage and then charge everything through in Mini2, in theory, during the flight, he should take into account how many mAh have entered during charging and use it correctly to calculate the percentage left ?
Thanks! :)
About the cells I will have affiliate links after I tested them (I do not want to promote something untested). I will update the description.
Or just search Aliexpress for LiPo cells.
About your question: Just make sure that the 2 battery packs are at the same voltage. IT HAS TO BE CONNECTED IN THE WAY I SHOW IN THIS VIDEO! ruclips.net/video/Nwx8i52qDEo/видео.html
Otherwise it will not work!
It doesn´t matter if you charged them together or separately. They just have to be on the same voltage. :)
@@ZollyD I wonder about cell balancing. The smart battery SOC has the ability to balance between cells, but without the controller the balancing can be significantly changed over time...
@@Jpeglism Correct! As I stated in earlier videos: These cells has to be balanced now and then.. Good input! :)
@@ZollyD Oh okay, so you were charging it through a balancer, right?
@@Jpeglism That is correct. :) I charged them up with a balance charger. Then after using it in the drone, I just charge them with the drone (which is so to say not balance charging the additional cells) but I double check with the multimeter. If they go out of balance I correct it. But rather just change cells, as they are not to go out of balance every charge cycle...
Cool stuff man!
Thanks a lot! :)
Impressive results! 👍😎
Thanks! :) I believe it will be significantly better with the new cells! we will see...
@@ZollyD that chinesee guy has 70 minutes by same way.
@@linuxettin That is why I am really curious when the brand new cells arrive..😉
@@ZollyD i understood at first bro, u just solder parallel right ?
@@linuxettin Yes, but not to the other cell, but to the connector towards the drone. Have you seen my other video?
Like your mods 👊🏻👍🏻
Thank you! I am glad to hear! :)
I always wondered what would happen to the flight time and flight capabilities if someone would remove the plastic frame of the mini. It would mean less weight, but is it enough to save battery. Wouldn't you think?
If you mean the top cover, then yes. It is over 10 grams. It does matter. If you watch The Longranger RUclips channel, when he does a world record attempt he is usually flying without the top cover. :)
I have two questions: 1) that Mini with the additional batteries will go way above the 249 grams, so if my Part 107 studying - still in progress - that will change the class of your drone, right ? In EU, it surely does, problem solved having at least an A1/A3 license (or even better an A2 as well), not sure about the US tho.
2) The tech problem I can foreseee is the change in the center of gravity of the drone, possibly disturbing the electronics (ESC, IMU etc especially having current flowing around those cables) and, most important, the extra strain you will put on the motors adding weight. I know a Mini 2 can easily lift even more than its own weight, but still.. it's a payload you are adding. I have no idea what the weight of those batteries is, so won't go in the relative math needed.
I notice you are very accurate in your experiments, so the question is, have you taken into consideration all these factors (aerodynamics in this case does not really matters much, although it does as well, but let's that aside for a moment) ? I am VERY interested in what you are doing and have thought about trying something similar myself.
Thanks for your interest! :)
1. Yes it becomes heavy and thus it changes the class. (To be honest -I think you can tell - I am not a cinematographer. I fly very little and I am not even good at it. I bought my drones because their technology interests me) But, yes if you fly a lot, the licenses have to be upgraded.
2. Yes it is changing the center of gravity. Not that much though to seriously influence anything (my observation). I believe it would be better to put the extra weight on the bottom, but I do want to have the sensors. As I said there is a sweet spot somewhere with the added weight/capacity. I am trying to find that. Plus I wanted to do this mod in a way, how you do not lose warranty on the quad. only on the battery :)
I will have a video coming out this Thursday. I think you will find some more answers in that.
@@ZollyD Can't wait to see how you managed all this. The sweet spot can probably be calculated, but I am not sure it won't fall in the wrong place. I wonder if it's somehow possible to mod the firmware in the battery and just change the cells... Not exactly legal, and not an easy feat, you'll have to reverse engineer the code and modify it accordingly, but I thing that given enough time and skills it CAN be done.
@@raquilano The reverse engeneering is already done by RUclipsr "The Longranger". So you are right, it is possible to change the battery firmware. I will demonstrate at one point his software (which I do not have yet) and the whole deal, I just want to get the DIY solutions out there first.
@@ZollyD Can't wait to see the results...
@@ZollyD any updates about changing capacity in the chip firmware to calculate percentage properly?
Very good job i love it
And can you extend size of drone please
Change or upgrade to bigger motor
,change or upgrade to bigger esc, change to bigger body, but use dji mini2 main board controller. Please
Thnaks! :) I think that is all possible!
@@ZollyD please wait your vdo
I like your comments!
Thanks! :)
I read about some batteries that DJ I sells with a Japanese model of the Mini 2 in which the flight times are only about 10 or 12 minutes but with prop guards and those batteries you're still under 250 grams so you'll be able to fly over people etc.
You can't order those batteries from the company that sells them in Japan because they won't ship to the US.
I wonder if you could try making a battery that along with prop guards keep the mavic mini under 250 grams.
I can look into it! :) No promises when, but we will see. ;)
well done very good video, new sub, thumbs up
Thanks! :) I am happy that you liked it and welcome to the gang! :)
My dji mini 2 battery duration in indoor hovering is about 30 mins..6 mins more probably it's too few gain for the job... At least we know now there's no check on battery board...wondering how can be with graphene batteries
great job, again . me new here but an old mini modder . just curious what is the difference on bms or software of mini 2 between the mini. that you cant use the same solution on mini1
Thanks! :) They are different but the same method should work on the Mavic Mini as well! :)
@@ZollyD i couldnt explain well ,i am asking this on mini 2 ( so no need a original battery)
:ruclips.net/video/EMUqGaAxafA/видео.html
How about a dropper activated from front led on the mini 2 that would be a great video bud 👍and no one else making them yet for mini 2 😉
YES! It is on my to do list! Oh Man, so many ideas for videos! I hope to cover them all in the coming 50 years! :D
@@ZollyD another great one today 👍
@@kylemnoble Thanks!🙂
@@ZollyD zolly would love to see 👀 a battery mod for mini 3 😉
hope you're well 👍
Thanks. I will wait for the new battery. Thanks again...
You are welcome! :) Me too. Some of them just arrived. those are Li-ion 21700 cells... :)
You have TRB, why you just don't unlock the controller? 😁
@@thelongranger7574 Haha. I do not have TRB yet. ;) But I will make a video of your awesome software, don´t you worry. Because I really want people to see all options. :)
We stay in touch! Cheers
@@ZollyD yeye I know
I’m talking about Jesus😂😂
@@thelongranger7574 ah cool! :)
I hope it can be applied to other drones like holystone hs700d 😁🙏🏼
I do not see the reason why it should not work. But I have not tested it on other drones, just the Mini1 an Mini2
You change the battery same time it’s fly?
Now you got high limits and weight limit problem.
Life is a funny game! 😂
How many charge cycles can I expect from my mini 2 battery?
That I would like to know too... :D I guess the general stuff applies. A fast google search says that after 200 cycles you are about to see 75% of your original capacity. I guess only time will tell, because the drone abuses those small cells quite a bit. Often close to 60 degrees Celsius. (140F)
круть
Spasibo! :) (U menja russkaya zhena) :)
Does the Mini 2 have a BMS lock?
Yes, it does.
Have you try a 9vdc power supply to the drone? If you do this without any battery in it you can have a long tether
Hi @Zolly . I watched your video so many time but I still couldn't connect between video part 1 and 2. I mean in the part 1 you show that the drone could fly longer but the measurement do not work and show 100%. Now it works just fine. I am from VN, I do not have knowledge related to electricity, but I do really really want to increase DJI Mini 2 flight time. Could you please a video step by step to help someone like me could understand and do it. I don't have much money but if you could do that I would be really appreciated and I hope that I could donate you some money, It's like paying a course for you to teach me how to do it.
Hi! I will make a part 3 and it will be all clear I promise. i am waiting for some cells from China. It is stuck at customs now for 3 weeks... 😩 When I get them I will make a nice vid about how to get this Mini 2 battery to the max! :)
I hope it will be soon now...
@@ZollyD Thank you so much. Can't wait to see your video. Thank you so much again.
@@ZollyD Hi Zolly, How is the answer going?
Does It work in mavic mini?
YES! :)
can i buy a ready batterie from you?
I hope you solved it in the meantime! :)
Please do dji spark
I do not own a Spark... But, if I get my hands on one to test I will do my best to figure it ALL out! :)
Hola puedes poner link de las baterías saludos
Sorry the seller is not in business anymore. Please check for Air 2S battery cells on Aliexpress!
Can you do a dji air 2s
I mean modify battery for longer battery time for air 2s
As soon as I get my hands on an Air 2S I will do it. :) I do not have that drone...
It's high time to learn how to print a battery case on a 3D printer. For high-capacity 18650, 21700 batteries. For all drone models. So that everyone can print a battery case for themselves and insert batteries for a long flight. Stop buying expensive new batteries.
Yeah! I am not experienced with 3D printing at all, even though I find it really cool. I wish the manufacturers would offer other batteries for their drones than the basic version! :) But like this at least we´ve got stuff to HACK! ;)
Don't you still need the mini battery protection board?
@@divingfalconfpv4602 Yes. Without the BMS the drone does not start. Once it is in the air it just needs the juice, it does not care about the BMS. At least on the Mavic Mini. I will test the Mini 2 as well.
Guess u can leave one bms board attach with xt30 and balance plug to connector other batteries
i fly 41 min in cinema mode with 1 battery !!!!! lol i dont know how the fuck ....
Lucky you! :)
Depois falam que Brasileiros que fazem gambiarra.

show!!!
