I think this is THE solution for everybody who dont dare to solder batteries. 👍👍
Even if you are comfortable putting a Li-Ion pack together, this is a better solution.
50 dollar spot welder on ebay. I would advise against soldering because of the amount of heat that is applied.
@@KAREKINFPV Or get a 50 dollar spot welder and make them yourself
@@hupo bro you say that like everyone knows how to connect balance connectors, like everyone has the right heat shrink, like everyone feels safe to connect it all. By the time you buy all that shit and make them, you could have had 4 batteries, ready to go at your place, with no time spent learning anything, or screwing up.
@@hupo i mean, i can buy 1300mah 1s lipo flat packs for pretty cheap, but do I make all my own freestyle packs??? no... because for a few more dollars they're at my house ready to fly.
Cool Man. You should put the amp draw in the screen and monitoring to keep less than 30A
I have 4 lion batteries I've been needing to solder together but it seems my procrastination was helpful because now I don't need to solder them. Great solution keep moving the hobby forward!
perfect, you are on the right track with these modular batteries
Great work Dave! I have used the same cells from old drill battery packs and they work great. I bought just the contacts so I can custom print the holder right into the quad frame or make custom packs. Another benefit is independently charging cells so their health can be monitored easily. Thanks for the video.
This if developed properly could help solve the problem of replacing bad cells without having to release spot welds. I think properly shaped low resistance contacts and insertion/hold tension is key. At present although seemingly adequate could introduce problems in certain scenarios.
This is such a nice self-serviceable solution to batteries, nomore having to bin a battery when just one cell is bad :)
I tried this a while back but I couldn't find good enough battery holders so I decided too scrap the idea. I've never seen a holder with gold clips. I'll have to revisit this again.
Finally!! I’ve been scouring the internet if someone has done this! Thank you for the video!
I really enjoy all your experimentation. Fascinating stuff!
Hey , I bought all the goods. Will you make a tutorial on how to properly put these packs together? Thank you
I just built such a clip and did the first indoor hover.
Seems to work and nothing is getting too warm for now
Will see how it holds up in the cinelog 35 soon
holy shit this is awesome! great job dude!!
Thanks !!
I bought a mixed pack of 18650 holders (single, double, triple and quadruple). I tried to fly my chimera 4 with three batteries and when I tried to take off it went about two feet up and sagged back down immediately. I'm guessing my mistake was that I used the power leads it came with. Way too thin. I'll put some 3S appropriate wires on and try it again.
To wire this all together, Is it just the case of putting the holders back-to-back, soldering the bottom ones together where they touch (as in 0:28 in the video) then bridging two of the top connectors together with a wire (as in 0:24 in the video), and finally connecting an XT30/60 to the last top two connectors. Thus creating a series connection from Positive to Negative?
Apart from the weight difference, what are the disadvantages or risks of using clip batteries like this? Compared to soldered batteries, is there also significant power loss?
Wow good idea. Do you have a video on how to solder that case?
Same idea as im doing currently. Bought separate and 2pcs of LiOn batts holder for holding total of 4batts. Not really happy soldering directly on LiOn batts. I prefer to charge them separately and allow me to play around with different brands of LiOn for testing
If you kill a cell just swap it out! I hope those springs maintains electrical connectivity after exposure to the elements for a while. Gold is good but the batteries might oxidize a bit. Also this spot is awesome!
It's like using ph2.0 on 1s toothpicks vs xt30 (For convenience, slight power efficiency loss.). I've used blossom sleds for RC trucks before, quality stuff. Shoe goo the solder joints and your good. For longevity get the nickel plated contact version. The brass oxidizes and loses efficiency faster.
Was surprised to see somebody has made these. Ive had some for a while printed out with fuses as the contact points.
Bottom balanced no worries about fires or shorts. Poor mans bms.
Thank you so much! It is a greatest solution for 4s battery for drone.
for this kind of topic ... I really miss Analog OSD
That is fantastic news! I will be ordering some for sure.
I had the same idea but you did it . now I got try it .
how do you make a 4s out of it , would love a wiring demo on it
I believe you just wire them in series. Since you charge them separately, there's no need for a balance lead.
@@slapjackftw would this work the same for lipos? i own a novice 2 that works by hooking up 2 1s batteries in series im upograding the flightcontroller to be 3s capable the motors are already 3s capable can i just hook in another connector and go? or is there battery balancing nessecary?
I'm a bit unclear about the length of the flight. Was it 5 minutes or 20?
Hi Dave! It's a very good job, will you make a tutorial on how to properly put these packs together? Thank you! :)
4 cells in series.
Oh wow, how did I miss this. This is great. 👍
Gantastic Dave🙌🏽 I think that's a great idea, and we are waiting the little video to how weld 2 or 3 slots to make 4 and 6s. So, one question, which what charger do you charge a lot of 18650 cells together??
There are 18650 chargers online. I've seen them used to recharge vape 18650 batteries for quick swapping. Otherwise you can find various setups for charging them all at the same time.
To be honest I'm intentionally never making tutorial about building batteries. I don't want the be the reason someone has this blow up in their face because my tutorial wasn't perfectly clear 😅
I was waiting for this video !!
Nice! 😁
Am gonna try this !!
Thanks for the testing! Cool video an ideas.
the osd would have been a good reference. why not dave?
quick and easy way to get 18650's in the air
This is cool, and thanks for the video, but man it's a bad idea, I can see soo many things going wrong. Exposed electrified metal, exposed 18650 batteries, a crash would be catastrophic, batteries flying everywhere, now you've lost a cell, or more. If you're in the us, there are companies who make ready made liion packs for FPV.
@Dave_C FPV Can you give us the PIDs for the 6S version with 4 li-ions ?!!
hey, can i see the detail about the battery, because i want to build it too
Kannst du bitte dein PID setup vom Rekon 6S für die 4s Lion packs teilen
Hehe Dave your antenna orientation from your Tango is off😅
Thank you very much for you testing!
Schöne Ostern
I hope retailers start selling these. I can make a LIION pack, but then it is single use. I use LIPO much more than LIION, and really only need a few LIION cells I could put in whatever pack matchs a quad when I want to fly it long and flat...
I hope they make a 20 to 30A 14500 soon. I'd love to have a much lighter 4s Li ion pack, like around 85g.
I would like to see something like this replacing battery straps
Have this solution here waiting my LR explorer arrive to test it. 😆
How did you connect the holders and attach the xt60 connector?
in normal liion packs, the cells are usually (?) joined with spot welded metal strips
i guess the small cross section of those welds is comparable to that of the contact points of the clips
if the cells were soldered with thick gauge wire, they might have less sag
why is the sag bigger when the contact points are smaller? as long as the metal strips dont get hot, there shouldnt be too much loss, right?
I think the welds aren't the only contact area, the metal strips have full contact to the cell :-)
@@mirkowaechter
the resistance of a conductor depends on lenght, crossection and the conductance of the material
R = L / (k * A)
if the crossection decreases, the resistance increases
smaller contact points increase the effective internal resistance of the battery
same thing with inappropriate connectors, if you were to use an xt30 on a full size 7" quad, maybe they would just melt
the metal strips might not get hot, since they themselves have enough crossection, but maybe there would still be a voltage drop over the weld spots
this voltage drop increases with current draw
U = R * I
@@marc_frank But if my quad pulls 60A and the battery is at 15V that means the total resistance from battery to motor and back is 0.25 Ohm. I doubt that the resistance of the spotwelds is somewhere near that. Or am I missing something in this calculation?
@@mirkowaechter idk what has been calculated by that
diatone has their motor internal resistance on the website
~50ohms
4 in parallel is still not 250mOhms
there might be something weird going on with the conversion of dc to ac
internal resistance of batteries is also measured in mOhms usually
Hey Dave have you tested this with 21700 instead of 18650? should provide even longer flight times
The 21700 have roughly the same energy density. Only advantage is higher ampdraw on some 21700
Hello Dave, I know this is an old video but I built one of these packs inspired by you ...the question is, what are the eligible drones I can use it with? can I use it with any 4" that takes 4S like a Chimera 4? I just need some reference for my next build... Thank you so much!!
Great to see that this works! Did you find any Battery Holders that have some kind of mechanical reverse protection when inserting the Cells? Gets even trickier the more cells you use...
Unfortunately not since the cells are completely symmetrical. It makes me a bit nervous too 😅
@@DaveCFPV well, with 2 cells there are 4 possible ways, one will fly, 2 should sum up as zero volts, one will smoke - think I can live with that...will mark my battery's positive side.
i know this is very old post but im thinking about something similiar for my 1 meter wingspan fixed wing, will use 40A t-motor motor. What you think? It will melt the plastic or even springs etc?
My conclusion is, I take a mid kv LR Setup for 6s and try a 5s 18560 pack or 21700? This would go 30min of cruising I guess.
Thanks for sharing! It is very inspiring
hello sir,i have 5 Inch quad with 4s.can i use like this?
How's the flight time compare to lipo?
Wow I need this
Do you have a connection diagram for that 18650 set up, the connection points for the clips?
can you balance charge these packs ? i didn't see a balances leads ?
Do you take them out of the case and charge the cells one by one?Please could you make a video of the build/charge?
From what I see, yes as there's no balance cable added to the battery setup
Coole Sache 👍. Nach 2x Rekon35 soll es jetzt eine Rekon5 6s geben. Und die Alternative mit 4x 18650 VTC6 hört sich gut an. Durch die Mods an den 35‘ern habe ich genügend.
Hallo. Kannst Du mit dem vtc6 Akku auch Flips und Rolls machen? Grüße aus dem Ruhrgebiet...
Jup. Aber zum Ende hin, geht ihnen die Power aus
I think not a good idea ,because when you crash the battery can losse contact with pads or even flip out from holder and you never gonna find your drone again without beeper.
That was not to bad with the 18650 interesting results. I been thinking of trying those batteries. To charge them do you charge them like a lipo ? Very cool video and enjoyed watching and the info. Thank you left a like
You could charge them up to 4.2 volts like regular light post but the extra capacity gain is nowhere near the cost of battery degradation charging from 4.1 to 4.2 volts only yields about 5 seconds extra flight time, nothing else and you're just killing the lifetime and cycle time of your cells
hi. where can i find this case for 18650? I need one like these, can you send me a link, please?
Do you think we could use something like this for the Flywoo Explorer LR4? Maybe a 3s system?
Moin! Would you say this exact quad flies better with 3S 18650 instead of 4S 18650?
Background: I am just trying to build the lightest O3 quad that easily flies for over 15 minutes for exploring on trips. Saw all the 4" LR Models but all seem to recommend 4S instead of 3S. (3S is minimum to have enough voltage for O3..). I though the extra 50g make it more sluggish. (I know +1 18650 is 15% more weight for 33% more voltage & energy, but then you could argue, get a 7" lol)
Please where did you get the battery holder?
I see what you're doing but based on your voltage, it's not in series, and actually parallel. Remember the difference between parallel and series. If you had it in series, it would be 4x3.7 after voltage drop which is 14.8v. in parallel, it would remain at 3.7 and bellow ; ).
You'll need to run a system they takes ~14.8v range for this to be a true series.
You've raised your 3.7v available amps in the setup you have, which is what you want if it can't truly take a series connection.
@@michaelbibby8636 Ah, I see. I must have missed that.
Personally, I found this clip thingy packs quite problematic. The key for flying li-ion is a very light drone with low amp ESC otherwise it starts a fire on a drone while mid-airborne. I would not recommend this for heavy and acro quads running on high Amp ESCs, though. An finally - 20grams plus on a small drone which weighs in total between 400- 600grams is actually a lot of extra weight to power.. You can basically forget about mounting an action cam additionally. I do not recommend this solution for regular drone flying. This li-ion is only good on specially designed aircrafts for use of it.
This is the way!!!
Hi, bei der rekon35 ja. Bei der rekon5 habe ich es noch nicht ausprobiert. Sie ist heute erst gekommen. Habe aber schon ein 6S 18650 gelötet.
Very cool spot to fly
Use some samsung 21700 T40 cells. 40amp discharge. Not much v sag with em.
How do you get the cells out of the trays? I’m gonna be running a 2s setup in my defiant Sprite but because I had to mount the tray in the foam, I need a way to get the cells out. Plus I’d rather charge them individually than as a pack.
You should use „35A continuous current Samsung 18650 2500mAh“ batteries 🤞🏽👍🏽 make a 4S Pack with Balanceleads , then you have normal 14.8V 2500mAh 140A 💪🏽 so it should have enough power for 35A ESCs 👍🏽👍🏽
BUT it does weight ~200gr since one Batt is around 48gr
Dave....why did you get to think of this first? You keep doing that.
So now with 4 batteries, what is the flight time ?
A question about the freestyle quad. Is there also a build in Step up, so you could theoratically use a Li-ion down to like 2.5V?
The moment the batteries were added to the drone, the drone became a lethal weapon. In my country, you would be immediately arrested for engaging in terrorist activities by putting something that dangerous on display.
I only seem to get 10 to 12 minutes on my Rekon 5 with the 18650 4s. 😥
Can you post how to solder this to have that like you?
I want a recon. Your site says they're in stock on the banner but the pages all show sold out.
Why are the Tress Elevated at this park?, is it to combat frost or snow etc?
Mhh... How about a set of 3D Printed Endcaps with reliably Cell contact making inserts already soldered to Balance and Charging leads? All the wiring would remain on the 3D Printed Parts out of which the Cells could easily be popped off. Securing the Endcaps to the Cells would be done via a suitably sized Heat Shrink that could be cut open for access to the Cells - I imagine the 3D Printed Endcap & Heat Shrink solution could shave off a some more weight compared to two of those carriers.
Awesome, im really considering picking up a Rekon 5 in the Future. Dave you were saying that the 6S version does also work on 4S, or which version are you flying here ? Saw AndyRC put a 6S 3000mAh Liion pack on his 1800KV version and he flew for about 30 minutes. Pretty insane for someone who can only fly the "normal" 3 minutes per pack like me :P
That is the 6S 1800kV version. It's the best option for 4S Liion too :-)
Would this rekon 5 build be practical in 6S Li-ion using t-mount 2203.5@1900kV?
Hey Dave! Could you please share a tune for the li-ion provide for Rekon5?
Man that's crazy, I had the same idea few days ago because I will never solder together little bomb like 18650! I had found other battery clip but now I will definitely follow your lead =) ! Did you solder a balance cable or you don't need it if you charge them separately?
I did it today and it works! If you have question about wiring it, I will be happy to answer
@@drze7910Just bought a 2 pack of these battery holders. How do you wire it up?
@@drze7910 I found a RUclips vid on how to make 4s packs out of these 18650’s….

Hey, great vid! Just wondering how to calculate, theese batteries can discharge at 30A tops (if put in serial(4S)), so this 13A ESC would eat 4*13A=52A, this is 22A more than the batteries can handle. Wont you damage the batteries? If I am not miscalculated.. Thanks!
That's just the maximum rating of the ESC. Doesn't mean the quad also pulls that many amps :-)
@@DaveCFPV Yeah but if you do a punchout it would, right?
awesome vid.
flight time?
I really want that battery clip, where can I get one?
I just want to know that the li-on 18650 batteries are much cheaper than lipos but still most of the fpv racers uses lipo for fpv flying . So is there any difference between the two in terms of performance ?? Please let me know.
If you are freestyle /racing guy you would prefer Li-Po, if you are longrange cruiser you'd prefer Li-Ion (18650/21700).
LI-Ion - longer flightime, less power output
Li-Po- less flightime, better power output

Hey Dave! I received my Rekon 5 last week and it's a 4S setup. After seeing this video I'm having regrets, wishing that I went with 6S instead. To convert over to the 6S motors, do I need to change anything else? Example voltage regulators for any of the components or a different PID profile?
Just the PIDs :-)
@@DaveCFPV thank you sir. I love the Rekon5 so far! I'll be flying at 14,000+ feet in the mountains of Colorado so I'll definitely be drawing more than 30amps against the windy peaks with a li-ion so 6S is the way to go it seems like.

Why is there such a tall building in the middle of nowhere? Strange
so i ordered the GEPRC CineLog 25 4S and searching for a battery pack that i can fligh for 10min - 30 min. Can i take the same pack like you for this drone?
it will probably work but handle pretty poorly and flight times will be on the lower end compared to a long range drone
@@DaveCFPV Do u have any idea what i can do instead?
