Incredible fabrication and problem solving. I finally purchased helping hands for my soldering station. I’ve been doing fine with pegs and pliers with rubber bands but the vice grips was genius along with the rejoining of the shrink wrap. I stumbled across this looking for mini 3 pro battery DIY but had to watch this masterpiece to the end. Thanks for such an informative video. Instant sub and like all day!
This whole series of videos on the Mavic mini is just awesome! I am investigating the feasibility of making an auto charging dock using some copper sheets of metal to charge the battery in situ. Watching your videos gives me the confidence to think it may just be possible! Looking forward to watching hte rest of your videos!
@@ZollyD Yeah I think it's definitely possible the more I dig in! I ripped the drone open and wired up a line to the power button and all the battery terminals then I'm feeding them onto the back of the drone. On the back I'll have a LoRa radio arduino combo which runs off the the battery power in sleep mode waiting for a LoRa on signal, as well as a YX mavic mini charging unit. which gets 5V 2.4amp power fed from two of the drones legs. The charger hasn't arrived yet but looks to weigh like 10-20 grams and the arduino lora radio another 10 grams. So It should only add another 30 grams. The only part I'm still uncertain of is if can charge the battery BMS with the charger while it's in the drone or if it's going to complain. Based on the way the voltage works with the power button (starts at 8 V then drops to 0 when you press the button, then returns to 3.3V when the drone is on), I can't imagine it being an issue as it looks like the drone isn't communicating with the battery at all when it is turned off.
That ending was great. I mean all your videos are awesome but that ending really grabs the attention. I don't know if everyone appreciates what you're doing as much as I have, but I think they do. For those who don't know what is involved in making these videos... It's not just pick up a camera and shoot some video. The amount of planning and editing and trial and error no matter how good you are is tremendous. Therefore I want to say thank you to this gentleman once again. Thank you for making us smarter every day. I wish I would have learned about you many years ago.
Thank you for spending the time to do these excellent mod tutorials. They are first class! I look forward to following the first video. In my ignorance i do wonder whether it would be possible to a) monitor the voltage and direction of voltage on the LED and the time period to know when it turns solid red and allow that logic to act as a switch to replace the push button. b) For the purpose of disabling the return home on low battery, would it be possible to use a mofset to act as a switch and to sever the lines after the battery check process is complete?
Amazing, Zolly! As I commented in a previous video, I would like to see the same process, but instead using non-solder 16850 cells that we can easily just slide into the drone's battery cavity then securely close the drone's battery door to lock them in place. BTW would it be possible to simply replace the original DJI circuit board with a DIY board? After all, it looks like you've already removed/replaced the original MOSFETS, etc. It seems this would be much easier to solder connections to. Thanks!
You can build an amplified antenna rig. It basically consists of 2 2.4ghz wifi panel antennas, 2 signal amps, power source for amps, appropriate cables/adapters, mounting hardware, and a tripod. It would also involve opening up and some light modding of your controller to connect the antennas.
Hey Zolly! Loving your ideas here and work done so far, I will go on to watch the other videos shortly also! A few questions... So, the Mini 2, I understand BOB will not work with this apparently? I am thinking out loud as I write this. BOB is a method to bypass/replace the "brains pcb" as you call it, I guess there must be something internal in the Mini 2 firmware that is not in the SE for BOB not to work? Ok, following on from that... there is talk about "locking the chip" by this I guess we mean the brains pcb locking? From what I gather this is done by the brains pcb losing all power? As an almost anti tamper device? Or am I missing something here? From what I understand in this video the power can be taken away from the brains and as long as the power is reapplied to the brains pcb BEFORE the brains gets connected to the drone then everything is good and the chip does not lock? Again is this possible with the Mini 2? I know you said you has bought one and made some progress with it, have you any links, videos, tutorials you can share for this as I am very interested in this :) Ok as for this video, I was thinking could this brains pcb not be internally mounted within the mini and wired off the back of the connector? From what I can think the issue is with the brains seeing the battery first and then plugging into the mini's connector 🤔 if that is the only reason could this be overcome? Again thinking out loud maybe a wire coming from the brains pcb into the battery compartment where all the brains and other connections are made internally and then in the battery compartment we just have a 2 wire connector to the battery? Granted you would only be able to use modified batteries from this point onwards, whereas having the method you have designed allows for both to be used... but just throwing some ideas in the air... Any help on the Mini 2 would be great if you can help me out 🙂 the last thing I want to do is have the chip lockout ... I have seen the videos about maintaining power to the brains whilst piggybacking additional batteries external to the mini 2, but ideally to come up with an internal mod board so home made batteries could be used instead would be what I am looking for a project on 🙂 Fantastic work!
Yes and no. The thing is that the board has to be connected to the batteries first and only after can it be connected to the drone. So if the board is connected to the drone while you insert the batteries it will give an error.
Hi Man, i dont realy know much about it but when you disconect cells From circuit board, board didnt blocked or something? Is this possible to change cells in battery to better ones withous getting circuit board blocked or something?
I'm trying to get my hands on the Japanese MT1SS5 battery to meet USA specifications for meeting category 1 specifications for over car and persons flying. At this rate I'm wondering if modifying a gen 1 or 2 battery with smaller lighter weight cells would be cheaper. Could I replace the lion gen 1 batteries with smaller lipo or lion to shave off 50g of weight on the original battery circuit board?
I am curious about that too, so for sure I will put it on my "to do videos about" list. One thing is already clear, that the full charge on the Mini 2 is higher than 8.4V. That is something to be aware of...
I would love that. Unfortunately the output-weight ratio makes them not too good for this application. As I know the solar tech is just not yet there...
Hi! Have you watched all my videos on the subject? I explain in them all the information needed. Parts, schematics, tips and tricks, whys and how´s and also the code for the microcontroller. Please watch them and if you have any specific question I am more than happy to answer! :)

Thank you for all the kind words! :) I am sorry to tell, but I am into digital electronics. I have not too much knowledge about analog circuitry, audio, and amplifiers. I think that is an area you are probably much better than me. I DO like your idea though to have an antenna on the roof and reach far. :) All I can do is to wish you luck with that project and please let us know about your progress. :)
Its amazing...using a bigger or second battery.... Hmm every fpv drone made...or all the hubsan 501 2nd battery hacks.... Or just search original mavic pro battery hacks from 5 years ago.
@@ZollyD Thats great to hear, i have mini 2 and ordered mini 1 battery to mod it and use in mini 2, but then i have found out it have to be programmed for the controller to use more capacity(amps), some moders say it works fine just like that without reprogramming so i don't know who to trust. It seems to me tho, i have found the One i can trust (:
@@xerxeslv Thanks! That was so nice to read! I have great news! I have bought the Mini 2 today!!!!!! I already started to mod it. It is a bit rough but I can proudly tell that I have already flown it with the batteries I showed in this video. The microcontroller program has to be changed though! So your thinking is correct. I also use the Mavic Mini 1 board and tweaked it with a micro. :) SO EXCITED ABOUT THIS!!! :)
I am not making these for sale. If you want to by some crazy batteries look on UA-cam for the user "The Longranger". Contact him! I know he is a good guy, and FOR SURE he has what you need! ;)
Hi Zolly Your work is great! This is what many people need :) but the point that it is more than 249 grams, makes me a bit sad. There must be an "hack" to make the batteries go under 249 g. Cheers
Yeah, the weight, the weight. Capacity always brings weight with it. I would love to have a super light 4000 mAh battery, but if I discover that, I am going to be a billionaire!!!😁😁
Good point! :) I charge them on a balance charger. I just stick a needle under the black plastic to access the balancing point. :) But they are not really going out of balance anyways.
no need to charge the balance all the time. after some time, need to balance to increase the life of the battery. zolly, what is the balanced charging circuit you are using?
Easy to understand without having to focus on filtering out unnecessary information (This is an example of how instructional tutorials should be formatted!!!)

Hi
Can u tell me how i can fit dji mini2 battery to dji mini
Thanks for sharing 👍
Glad you liked this too!😉
Hi i have damaged battery means no BMS is still that trick will work plz guide me
you could make a battery compartment where you only change the batteries, or is not possible ?
Yes and no. The thing is that the board has to be connected to the batteries first and only after can it be connected to the drone. So if the board is connected to the drone while you insert the batteries it will give an error.
I ordered the bms already unlocked from Pat to connect a lipo under 200 grams, for my mini 2, to do a test with my alientech duo 2.
