these sony murata cells will work fine. the original cells can handle 120c or 140c, but that will never be used - the battery connector can't handle that current (if the drone draws that much current, the battery will die in a few seconds, not 20- 30 minutes) your soldering iron doesn't have enough power to solder well such thick wires...
best of all: first approach with 2p shematics was perfectly drawn In the second you decided to abandon the 2 adventure your sketch was hands on. pretty interesting to see your bms cable being faulty sorted if I understand it right. I just have to refit a 5 cell 18650 battery pack for a gardena lawn mower roboter with samsung inr 35E and 3,5Ah but 10,5A only . That has a bms too and I had written down each cables colour and cell position during tear down to get it right ... But the basics are the same except my packaging needs to be a 3 x 2 cell solution, hexagons as a holder to get a battery that will fit into the bay while you're piling it as a 3 x 2 stack. My hight has to be as low as the original.
Thanks for your kind words. I want to figure out a way to do 12 cells 6s2p but having only 3 wide and 2 tall and longer. That would be ideal to fit ontop of the quad.
This type of battery construction we rc model enthusiasts did 20yrs ago with Nicad and Nickel metal hydride and we experimented lithium ion batteries to but they had very low discharge rate. excellent instruction btw.
Hey Rafael awesome you took the time to watch and comment! Much appreciated! Very cool. Back then I wasn’t into building my own batteries yet but of course it makes sense. Just today we have better batteries available. Thanks for being here!
Just made my first 18650 6S pack tonight out of a battery bank someone gave me with a bad usb port or bms. Can't wait to test it out tomorrow if weather allows but i only have a 5" to test it out on at the moment. it did fine on my unofficial indoor hover test.

I dont mean to be so offtopic but does someone know a trick to log back into an Instagram account..? I was dumb lost my account password. I appreciate any help you can give me.
@Yahir Prince Thanks for your reply. I found the site thru google and I'm waiting for the hacking stuff now. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
Really nice looking outcome. Couple tips: a flux pen can be used to pre-flux surfaces (especially larger ones) to clean the surface and enable the solder to flow easier and quicker. Also on the XT-60 connector besides the flux pen if you plug in the other side of the plug it helps even the heat out so one end of the plastic insulator doesn't overheat and start to melt.
Hey Johnny, thanks for dropping by again. You know I should have known that with the flux pen. I have one, not sure why I didn’t use it. I guess I was worried about the liquid flowing in behind the positive cell button. The trick with the xt60 I need to use more often as well. Great tips! I feel a fatter tip would have made it a bit easier also. Next time ;)
12:26 yeah, I’ve done that once. Quickest way to give myself a heart attack. Luckily there wasn’t a fire, just a lot of sparks and a COMPLETELY dead battery. I’ve actually tried this numerous times, but until today when I watched your video, I couldn’t figure out what I was doing wrong. But i figured it out, thank you.
Very cool video here. You have a great speaking voice too. I gotta study what you did here a few times to better understand exactly how you did this. One thing I learned for sure, is having the proper tools, and material for the job. That's over half the battle, lol. I went through a lot of soldering tips, learning how to solder correctly. I like the soldering cleaner you have too. Gotta make one of those. First time viewer here. Thanks for a fantastic demonstration. Liked and subscribed.
Hey Al B thanks for taking the time to comment and watch, it is much appreciated! Glad you like the videos, oh man. How many times have I done a project without the right tools. Always takes 3 times longer and 10x more frustrating. I try to avoid that if possible haha. Glad you are here!
Nice I'm just learning how to build lithium ion packs. I choose to use battery trays but I will make a couple of packs like this as well in the future. Keep up the good work!
Hi...my favorite part is how far you have taken FPV in so short a period of time. Building a 7" quad, and building your own batteries is remarkably adventurous and encouraging to others; myself included. I know you have done the hover test. Have you used these under real world load conditions such as fighting gusts of wind at high speeds? If so, what are your observations?
Hey mosephina, thanks for taking the time to watch and comment. It is much appreciated! Glad you enjoy the FPV content on the channel as well, I'm glad some are enjoying it. Great question. I took it out to do a flying test, it was a very windy and gusty day, i flew 40-55kmh average and still got 14minutes of flight time. I left the throttle mostly steady and used other inputs to manage altitude etc. I was pulling 8-13amps max, with 2 of these batteries in parallel, I'm sure even decent manoeuvres should be fine. What are you flying thats similar?
I have obtained those green cells from power tool packs to add to my electric skateboard. Gain .... range has gone from 25 kilometres to 42 kilometres. Speed the same, obviously
Also dji sells battery smart boards so you can not only make your own but you can make a you're own smart one.. temp sensor, bridge etc also connecters so it will slot rite into the drone if your that good
Hi, I'm really pleased that I came across your site, I'm a beginner drone flyer, really loving it. I've built an Echine Tyro 129 but the batteries are really expensive, I've got a bundle of Panasonic 18650AA 2250 mah batteries from a damaged ebike battery. I've already used some to replace the old style batteries in my 12v,18v, and 24v power drills, I've got 16 left. could I use them to fly this 7" drone ? It weighs 400g without a battery. I could build 2 x 6S1P packs or 4 x 4S1P packs. If they are suitable, what would be the best combination? I'm familiar with building 18650 packs, but I get mixed up about watts and M.A.H ( I'm in my 70's). I've subscribed, loads of useful info. on your site, thanks.
Great Video absolutely love your content started on a cheap Walmart drone. Now on a Mavic two pro and Mavic mini and hopefully soon Mavic air 2, Still nowhere near being able to make battery packs lol
Hey Pie Inc Reptiles! thanks for taking the time to watch and comment. Much appreciated! Starting on a cheap drone probably got you comfortable hovering a drone that didn't just sit there perfectly still. Great skills for the event that GPS hold would fail one day. Do you recall how you came across the channel?
Quadcopterguide honestly after I started getting into drones I couldn’t stop watching RU-vid videos on them and finally just stumbled a crossed your channel by pure luck.
@@pieincLockPicking88 haha sweet. No worries, glad you came across the channel! Hope you enjoye your stay ;). Also, if you haven't seen it yet, here's a bunch of helpful content for the Mavic 2 Pro and how to get the most out of it. Feel free to check it out here: ru-vid.com/group/PL0ymhIrvXFKf1SOISAto0OaqSCLtNi70R
Great video. Few things, you're not pre-tinning. You're tinning. It's one of those weird things like a "hot water heater". Why would you heat hot water? 🤔 Also, you can buy small tinned straps to connect the cells and keep everything flat. Something to look into. 👍👍👍
hey fmf thanks for watching and taking the time to comment. Much appreciated! Will keep that in mind. My research showed that the tinned straps handled less amps as the silicone wire, why i went that route. Maybe in the future, then I would want a spotwelder too muhahaha :D
@@Quadcopterguide I think everyone should have ALL the tools. 😆 I'll have to look into the amp rating. I would think that there's more material, thus more ability to carry amperage, in the strips as long as they are the right size. Maybe not tho?
You should look into a small spot welder. Soldering Li-ion batteries can be dangerous and with the ability to do it completely safe it isn't worth the risk, plus it cuts down on the size and production time
Just to be clear this will only work good if you're drone consumes low power consumption when we're talking about most of your mavic products were talking about amperage draw a higher C rated discharge battery is required which is why they use Lithium Polymer instead of lithium ion if you were to make the same attempt on a regular mavic platform you would find really quickly that you would start running into serious instability in the platform because when it goes to draw that extra energy that it needs for the power boost unfortunately ion does not provide this and you will have what we would call a system brown out. the Drone will go into complete system shutdown during flight and it will fall out of the sky like a rock. So basically you really want to understand how this system work properly before going out and attempting flights on this type of setup because there's another thing that has to be considered in that is wind. These battery builds with ion are great if you're just cruising around but if you were to run into a gust of wind and the Drone wants to continue its course it's going to need power to fight the wind and if it over drawers the capability of the battery then it will Brown out. Good video brother this is the majority of what I do on my channel is showing people how to take proprietary drones and Design hobby grade setups for them so they can use hobby grade batteries instead of proprietary based system
Correct, the burst power available is less than on a LiPo, as mentioned in the video. That's why I planned this to be a 6s2p pack on the 7" quad to give me 60Amps, It ain't no 200Amps which the drone can pull on full throttle, but the limitation must be known to the pilot at the controls. Most DJI camera drones use LiPo High Voltage cells also, so pairing those with even just regular LiPo wouldn't be safe. I would advise against tinkering with any LiPo pack anyhow.
hey thanks for the comment, you can catch most DJI drones in your hand and tilt them over 35ish degrees and the motors will stop after they try to spool up quickly first.. I always found that a bit risky.
Cells put in series do not self equalize,,,thats why we need balance chargers. Cells in parallel self equalize and. I've experimented with it and I've seen currents in excess of 20A with high discharge Samsung cells, one at low low voltage and one full. The current drops quite fast though and within 3 seconds I'll be well below 10A close to 5A.
When are going to post the next video,I have tried and got an outstanding performance man it helped me a lot will making a race with my drone, thank you for the mesmerising Idea 😘
Hey Ammu awesome you took the time to watch and comment! Much appreciated! I plan on posting it this weekend. Just remember that these kinds of batteries aren’t meant for insane speed or 6s racing quads.

I’d like to build a simple 3s pack for a bebop 1 drone. The original battery is only listed as 10c, I’m assuming 20c burst. Seems like you could easily buy some ions that could handle 20c.
Hey IV, thanks for taking the time to watch and comment. It is much appreciated! Sounds doable for sure. You just have to make sure you get a matching plug and if there is any fancy circuitry you would have to transplant that.. No experience with that so far.
Thanks for the reply. if I went that way I’d probably lose the proprietary parrot connector on the drone for an XT60. There are other videos out there with people using standard 3s lipo packs on these, so apparently that part works fine. . I’ve just never seen anyone using lithium ion before.
Great video! I just purchased my first soldering kit and this tutorial is a great visual reference tool (even though I won’t be doing any battery fabrication) but watching the way you soldered the wires was very insightful. Now, at what temperature in degrees did you have your soldering pen set to for this job? Thanks again for this.i learned something new from it. I look forward to your next video on testing the battery 🔋 👍🏻
Hey Drone Syndrome! Thanks for tuning in again man, super appreciated. Very cool about your first soldering kit, what did you end up getting? My soldering in this video isn't the best of my work, but I wanted to get this out before re-shooting the whole thing later again. Ideally you want to heat up the surface, and the solder will flow from your pre-fluxed wire onto the pad or whatever you are soldering to. I had the iron at 400C for pretty much everything this time. Glad you enjoyed it! Makes creating it worth it.
Quadcopterguide I got a $20 one on Amazon. Nothing too fancy. I just wanted to have one handy for when I need to repair or assemble something. But the one you’re using is pretty cool looking and seems to do the job well.
Quadcopterguide I agree. I’m a newbie to soldering so this is fine for starters. By the way, this is the unit: www.amazon.es/Tayg-59002-Electraline-Mult%C3%ADmetro/dp/B00CBJOOUA/ref=mp_s_a_1_6?dchild=1&keywords=digital+multimeter&qid=1595836157&sprefix=digital+multi&sr=8-6

Hey mixchifius, thanks for taking the time to watch and comment. Much appreciated! Can't wait to share it with you guys. Let's just say, it was worth the effort ;). Stay tuned! Whatcha flying these days?
Hey David, awesome you took the time to watch and comment! Much appreciated! I don’t think building this type of battery for the inspire 1 would work. A) it needs high discharge batteries and it has the chip.
They are heavy which is why DJI doesn't use normal lithium batteries. So it takes more power to fly with more weight. Go with Samsung 35E 18650. They are pretty much the best you can buy right now.
Building a 6s out of 27000's is a royal PITA. I made some 4s and 6s and the number of solder operations you have to do per battery is 50-100. It's tedious and insane. And it's a mute point now, because I plugged an XT60 in backwards to my 7" fpv quad and blew out it's ESC. So that XT60 connector is a killer just waiting to happen. On all my yellow XT60's I had labeled them with a red/black sharpie +/-... so that would not happen... but guess where that one singel black female XT60 was... you guessed it... on my $500 quad. In under 1second while working on the bench going back and forth between Betaflight and the quad in a hurry, bam spark and that's the end of the ESC music and my $500 quad.
oh no! Did the black xt 60 get soldered on wrong? I haven't been able to plug in an XT 60 the wrong way, if you managed to get that to happen.. holy cow! :). I hate learning through mistakes like that..
@@Quadcopterguide my guess is spark gap jump... Round male in square female touching and other side is only a hair space between contacts. 20v at 2 amps yeah... kapow... and its game over. Wasnt jamming or anything, I was just in a rush on the bench and my mind wad inside betaflight configurator
@@Halphbaked210 I bought a replacement ESC, and capacitor. It's been sitting 3 years now unfixed. I was too blind to gut the thing all the way apart and do the swap out, even with an inspection microscope. So yeah, pretty much bye bye 500 quad, and then bye bye another 80 replacement ESC that never could get installed. I mean bye bye in a sense, I still have it all collecting dust. But after one flight, I never flew again... nor did I ever want to fly again, that pretty much ruined the hobby entirely for me, game over. I couldn't go back. I didn't understand why, until I had an epiphany one day... a phrase that popped into my mind. Sudden Infant Death syndrome. It's like when your first baby dies, through no fault of your own.

Hi, I wanna ask: I have a Parrot Jumping Night Drone: Drone: 3.7V 2A Max Battery Pack: Li-PO 3.7V 550mAh 2Wh 15C Cont Discharge Battery is dropping. Usually I can play up to 20 mins, now below 5 minutes. I want to diy using 18650 battery. I have AWT 3500mAH 3.7V 35A High Drain and MXJO 3500mAH 3.7V 20A (both are authentics). I use for vaping device. - Can I use my vape battery to drone? I plan to mount only 1 battery, probably using battery slot so I can easily recharge it. I have Nitecore UM2 USB Charger. - If can, do I have to tear down the original battery, take the BMS and put into 18650 battery or I can simply soldering cable at drone connector to the battery without BMS? For safety reason, which is best? - Also, there are 3 connectors on the drone, I think 1 for battery level, how to soldering it so I can see the battery level on the smartphone. - I think with 1 single 18650 battery with 3500mAH, I can get very longer play time. I confuse with 2A Max warning on the drone and 30A or 20A on the battery. Can you help giving me understanding about it? Waiting for your feedback. thanks.
hey there, sounds like the battery or some of the cells are going bad. as long as your voltage is the same and the cells are high quality it should work.. There's a lot of risks with messing with batteries. Please be sure you understand those all before you start on this journey.

The voltage doesn't balance in series, it balances in parallel. That's why if a cell dies in a battery pack, it'll take the whole parallel group with it, but all the other cells will be fine. The cells in parallel will discharge into eachother, which is why the cells in parallel need to be similar voltage
Soldering cells , no matter how careful and “quick” you are this is not advised process. There is a a few videos out there that show thermal of the effects of soldering on cells
Hey rain awesome you took the time to watch and comment! Much appreciated! That would be sweet. I’m not sure how we could without the chip inside the batteries however.
I purchased a Ghost drone 2.0 and the battery lasted 4 flights before the batteries puffed up. Customer service was none existent. So its been sitting on the shelf for 3 years. I recently purchased a lithium polymer battery twice the size as the ones that failed on me. I also bought a versatile charger. Do I have to use the original battery monitor and on/off circuitry? or can I just plug in my DIY battery . Id really appreciate your ideas. oh i also purchased the iOS model...being an android guy all the way. Can i download the android software to avoid wasting money on ios?
Hey Ard! Thanks for tuning in. I had 21700's on the radar, but since I really want to go 6s2p the extra weight of the 21700's didnt pan out. I think 6000mAh in a 6s2p of the VCT6 pack is plenty. Worked out to be lower g/1000mAh ;). Sure i will only have 60Amps vs 90, but it'll have to do. Hey let me know how ur Mavic flight went!
Quadcopterguide No worries...18650 are fine and there are some high capacity available. You looked to be using either Samsung or Sony.....but stay away from some others as they are poor and do not deliver the amp hour stated. I will when I fly it lol.....still hunting an apple device as I want it only for the drone. I do hold it everyday if that counts ha ha
@@ardscorner haha. Yes these are Sony/Murata VCT6 cells 3000mAh 30Amp. You are a patient man :). I think i would have sent it up with whatever by now haha.. Enjoy the hunt.
I decided to share with you since you were the first post to come up since I did a search and got no results, maybe you will get rich and share, but unconditionally here is my idea, we have power banks here like a 20 mah with the standard brands how about selling a drone which utilizes the standard most popular brands and can just connect to pockets full of power banks
So do you recommend your masterpiece can be used to plug the commercial mavic or Phantum...leave it for a while as to how to connect it with quad but if connected, will it work ? If it works, damn !!! I'm gonna able to multiply flight time (with bit compromise on weight) ...
Hey Imran, thanks for taking the time to watch and comment. It is much appreciated! it is possible to hook up extra batteries with some hacks to existing camera drones. They have to be different cells than these Li Ions though and it's not for everyone.. Of course it voids any warranty you have...
Awesome video DIY making it simple! Just curious, can you post a link on where to find your battery meter? I'm all set on a multimeter but your battery meter looked excellent. Thank you
7:08 mis-spoken: "series" should be "parallel". If in series, no current will flow between the cells because the circuit isn't complete. Adding cells of different voltage in series will just add the voltage of each cell up onto the cells before it. In parallel, however, as soon as you connect the two 6s series batteries together, current will flow to equalise the total voltage of the two 6s batteries and, as I understand it, if the difference in total voltage of each 6s battery is big enough, you could end up with a high current which may spark/ exceed the max charge rate of which ever 6s battery has the lower voltage. So it's important to make sure the total voltage of each of the two 6s batteries is the same before you connect them in parallel 👌
Also, check out the Molicel P42a 4200mah 21700 cells. I built my li-ion battery out of them. Much higher volumetric energy density than 18650 and has a continuous discharge rate of 45A
Good Morning Daniel, had to do a double take. The cells are wired in series, that is correct. The rapid flow of current occurs when plugging in two packs in parallel, that is correct. I should have said "you want the cells the same voltage to ensure the final pack has similarily charged cells". Your warning about plugging in packs in parallel is 100% correct. The general rule is no cell should have a voltage of over or under 0.1v difference, before plugging in in parallel. This occurs when you plug them onto your parallel charging board etc.
Love this conversation by the way. So glad others are into this kinda stuff. Funny, my spreadsheet I used for planning has these VCT6 cells on it and the Molicel you mention. You're spot on for a planned 6s1p pack the Molicel make sense. My plan from the get go was to do 6s2p and for that the Molicel was just too heavy for me. My calculations were that a 6s2p ( or 2 6s1p just manually wired in parallel) pack of vct6 weighs 624g and the molicel 876g. 6000mAh would be plenty i thing with the vct6. The vct6 packs would provide 104g/1000mAh and the molicel 109.5g/1000mAh. All these calculations were assuming the VCT6 provide 3000mAh. Initially you can get 3130 out of them even. What are you flying with li-ion packs?
@@Quadcopterguide yeah I think your 6s2p set up is perfect for you. I'm running the Molicel's as a 5s1p on a 5" fpv drone. Definitely heavy for a 5" but I'm getting 18 min flight time, just crusing around. Current draw is about 10A while cruising. If I had a 7" I would probably go with your set up, but I think I'd have to experiment with the Molicels 😆 The extra max discharge current could help if needed to do an emergency punch out. What's your current draw while cruising with this set up?
@@Quadcopterguide spot on. I've also heard about the 0.1v per cell in series general rule but only in relation to lipos, which can safely take up to a 5c charge rate. I wonder if the same is true for li-ions, considering their max discharge current is much less than lipos and so perhaps their max charge rate is also much less, which could mean that 0.1v is too high. Would love to know the answer to this!
Just curious, what happens when you draw more current than the C rate of the battery? From what I could gather from what you said at 6:04 it puts more strain on the batteries? I am not super bothered by performance, I just want to be able to fly for longer. Nice vid btw :)
if you draw more than its rated for the voltage will drop quickly and you risk undervolting and shutting off your quad in the sky. The life of the battery overall is also negatively affected.
Hey drone pilot, thanks for taking the time to watch and comment. It is much appreciated! The original Mavic Pro had a 3 cell battery. So if you mean MP then 3S max. Not sure if the weight would be too much.
An amazing video . I was really searching for something like this . Though I still have a problem . I have made my own cinewhoop recently . A shendrone geyser. It is a little heavy since it's a 4 inch cinewhoop and the ducts add up the weight. Plus if I am flying with the go pro , the 4s lipo only gives me only 2 minutes of flying time ( without go pro 4 and a half or 5 minutes ) . Will a lion help me get more fly time. I am using 2300kv motors . I am still not confident that a liion will help my drone get off the ground let alone increase the flying time. Is it worth trying ? Becasue lipos suerly aren't worth it .
Hey Simran, thanks for taking the time to comment and watch, it is much appreciated! It may be difficult I would be worried about the drone pulling too many amps. What is the max amps in your typical flight?
@@Quadcopterguide I have 40 amps motor so the total consumption is 160 amps theoretically still around 130 - 150 amps would be sufficient. Which is provided by the lipo. Since the li ion cells which I have seen hardly have a rating of 2c . Some can ( like the Lg and samsung ones ) prove 5 to 10 ampa but that too in burst . The quad itself is 442grams without battery and go pro .
@@Quadcopterguide I am looking at 8 cells connected together for now . The lipos are certainly not worth it . I am just fed up of changing the packs for two minutes of flight time . Since I only require gliding power for a cinewhoop ( I dont need to do crazy throttle consuming freestyle stunts and all )I thought I could go with the li ion alternative using only 40% of the full throttle .But now after just reviewing everything I get it why people build a 6s cinewhoop . I think I might have made a mistake by making it a 4s config. The only alternative which I can think of now are mobile batteries . But good mobile batteries with high c rating cost a fortune .
Hmmm ... based on your cover image, holding up a Mavic battery, I was hoping you'd show a way to take an old dead Mavic battery and use the 1365's to bring it back to life, perhaps at a lower capacity. But the video has nothing to do with the Mavic battery.
Hey dkuchta5, thanks for taking the time to watch and comment. Much appreciated! I suppose if one wanted to, and was able to, they could carefully take the outter shell off and see if its a single cell that's bad or the intelligent battery controls. Honestly, with a battery like that I would just try to find another replacement online. Is it just one?
@@Quadcopterguide No I don't have a dead battery now, but likely will at some point. I just thought, based on the cover image, that there might be a way to revive one cheaply when that happens. My default assumption is that there is not, due to the more complicated circuitry for smart charging and partial discharging over time. But your cover image gave me hope! Now, that hope has been dashed on the rocky shore of despair, alongside the rest of my broken dreams ... (sob. sniff.) Sorry, got a bit choked up there.
haha don't let me get you down man! I have a feeling that if a stock charger can't revive the battery something major has gone wrong. If that day every comes, let's see and hope not!
Hi Peter, thanks for stopping by and taking the time to comment! Awesome! Theoretically that is possible, but you would have to use regular LiPo cells, and at that point it's simpler and much safer to just buy an off the shelf product. The Mavic Pro uses LiHV type cells in the main battery so Li-Ion will not work.
Hi Vindula, thanks for watching and commenting. I sure do appreciate it! You have to charge them with a specific li-po charger. No LiPo should be charged un-attended, and proper fireproof charging locations should be used.
Hi Arunava, thanks for taking the time to watch and comment. It is much appreciated! It all depends on which cells you use and your amp draw but yes, they are safe, if done carefully and properly.
I was wondering can I maybe have two packs on my drone paralel? One would be li-po to have big current when needed and second pack with li-ion to increase capacity. But I will need to invest probably in 7 inch drone before testing this approach. :-/
mixing lipo and li-ion sounds like a bad idea on paper. Not sure you would want to do that.. Try to use the same cells so internal resistance and everything else is equal.
hey Andrew, thanks for taking the time to watch and comment. It is much appreciated! Mobile phones normally use li-ion cells. Same as these just a different shape. Hope that helps.
all depends on the required voltage of a quad.. IF you mean an fpv quad, the 6s pack would have more punch. If the total mAh are the same.. now that would be an interesting test.
