Most people don't realize how much of our modern way of life we owe to John B Goodenough not only for lipo lion batteries but even ram and transistors kinda sucks that the new lithium ceramic batteries have lower power density considering they have none of the drawbacks of lipo batteries even in regards to operating temp discharge/charge rates and dendrites
for those that dont remember the days of nicd and nimh know damn well we can use AA's in rc toys. lol the drone community acts like all this stuff if new uncharted territory.
Basically it's the internal resistance that are sagging out the voltage as more current goes through the battery, basic physics, so this is why we used lipo cuz the internal resistance won't be taking out a lot of voltage in the process of discharging (ie internal resistance -> heat, that's why the bat pack got very hot)
I would have tried tethering it and flying it like an old school RC helicopter, like the one I remembered my grand dad flew back in the early 80’s a good 30 feet of wire hoooked up to a car battery.
Wouldn’t it have worked better if you used different motors and props that were designed to be super efficient? The old school Flite Test guys used to fly their H quads with 8” 2 blade slow fly props and 2212 motors with wooden booms and everything. That combo pulls max 10 amps with the right pitch prop. x4 motors and your like 40a punch outs and maybe max 20a hover. And they did that on 3s, so less battery than you all used. Anyway, I think this rates a revisit but done with different hardware. Time to call David “The Swede”.
For the record, we tried like five other things that didn't work, including lithium AA (just as an example), and calling in David Windestal for advice, but not all of that made the edit.
I was just walking through walmart yesterday and thought about doing this myself when I saw some AA batteries on a shelf, now today you upload it! That's so weird
18650 battery's is a viable option for a long range 6" - 7" quad, they even use them on 3". But there is not a lot of videos out there about this topic. Maby a idea for future RR video ? Anyway , loved this video and its so nice to see a channel like RR doing fun experiments and not only showing different flights like most fpv channels does
@@Thelango99 Sure. By AA batteries I meant the standard ones - alkaline or, if you want rechargeable, NiMH. Not specialty ones like the lithium batteries.
Love this kind of content! Great video! I would have used AAA batteries, and then connected 3 sets in parallel with some capacitors to handle current spikes.
Nice episode. I'm currently playing catchup on your back-cataloge. I recently watched one that had two pilots swapping control of the kwad by handing over the transmitter. You've also done one with two kwads stuck together and the pilots arming their one depending on which way was up. Can you do one where two pilots fly one drone, no swapping transmitter; each pilot controls one gimbal.
ahahahahahah I couldn't stop laughing when he soldered on the wrong type of XT60. because when i built my first quad the same thing happened to me and I also got the same face expression XD
I hope that when I have kids some day that I can show the same level of excitement when they bring me their arts and crafts as Le Drib when the drone arms on double AA batteries.
Placing my bet: Very saggy, very heavy. Will struggle to hover, more likely just spin the props and not lift off at all. Compared to lithium, alkaline chemistry has much higher internal resistance. Because the voltage is lower you need more cells in series, and the series resistance adds up fast. Energy density is qctually not a huge amount lower than that of a lipo, maybe 30% to 50% less guestimating based on equivelent energy in 3 AA's as a single 18650, but an 18650 has almost double the energy density of a lipo. A 1500mAH single cell from a lipo is probably roughly equivelent to 2 AAs. Problem is of course, power density. That ESR severely limits the amps. My guess for the best configuration will be 10S3P
Normally AA battery (that's of classic Alkaline variety) carries between 2 to 2.6 Amps hour of capacity, and very importantly, the internal resistance is also crucial since it alone can determine how much energy those batteries can actually dump without too much trouble. Generally Alkaline batteries suck compared to the Lithium-ion batteries when it comes to energy density per cell weight. Obviously Nickel Metal Hydride cells would do better than the Alkaline batteries since they have much lower internal resistance (closer to the Lithium-ion cells for some brand cells). Nevertheless that would be a fun experiment.
My motor prop nut doesnt fit properly(cant screw it down all the way so that it sits on the prop ) how do i fix this i have to use a spacer so that it fits tight
I'm only a minute in and am guessing you did manage to get it to hover at least. Whatever the material & quantities of they make Duracell batteries with has got to be a closely guarded secret, I found a set of 4 Duracell AA's in an old RC car and after 30 years (or longer) they still read 1.46v, no leaking, can still be used.
@@smooth_ops2942 Yeah they must've changed their recipe in the past decade or two, Duracells made in that time do now leak. When rechargeable AA's turned up I used them as much as possible because the cost saving over continually buying alkalines was massive. Now I rarely need AAAs & AAs, lithium batteries are reigning supreme, although I wish more devices had user replaceable lithium batteries.
Yes... You need power... But doing the same power with lower current (aka higher series cell count) will works better for high internal resistance cells like aa
I did Fly a 7" 6s Drohne on 2s. It works just fine, But has a little to less Power. But that was expected. I think i can Fly whithout any Problems whith 7,2 v (6s nimh) car packs. Also i tryed lifepo4 Batterys and this works as well. Also li-ion packs are very Good. I also did a test whith a NiCd pack from a Drill. Also packs for our lawntrimmer work fine. The heavyest Batterie pack was a lead-gel/ lead acid 12v 3A one. It was flyable, But had a very big voltage sag(down To 9v) I also used my old and very Bad whoop packs to Made a bigger pack. Also i tested supercapacitors, cellphone Batteries(removed Protektion circuit) and a intro Motor whith a Generator. (this was the only fail, Not enough Power from the Generator)
Their was a guy who posted on the mulitcopter reddit page of a micro with a single 18650 batter as power. He said it was self made. Is there something like that out on the market?
What’s most likely going to happen is that the excessive heat from forcing current draw from AA batteries will destroy the anode and cathode, burn up the dry electrolyte before the battery will drain. You guys should really of done the more Scientific approach so you can determine how many AA batteries you would need to actually fly the quadcopter and see if you can pull it off. I would recommend using 6S+ motors because with higher voltage, it’ll use less current draw which is where the AA batteries suffer the most.
Scientific research? Guy, relax. It was just a little video idea to see if it would work. I doubt they actually care about spending the time to research the shit to make it work
How about give it another try with a 1 cell drone, oversized props and 3 AA batteries (4.5v). Can it take of with that weight :P Great video as always!!
And in this episode of "Rotor Riot have no science skills and think they can just mash things together"... The fact that Sam could to a full roll and land gracefully again, but they couldn't even with *his own method* tells me there's something seriously wrong going on there.
Lol, you should try bigger build. I got one 15inch props with 4822 390kv 6s drone, It lift well at 5amp. a single motor will produce 1.5kg thrust at 12 amps
So... it didn't occur to any of them to try a 4" ultralight? If you're trying for the most usable setup that can haul a Vista unit (barely), that's going to be the most likely candidate
Guys , please, SAFETY... even being almost impossible to just fly away or burst into psico mode, testing live motors with props indoors just contradicts PROPS OFF master voice!
I'm curious have you guys done a video on different types of lithium batteries...... That would be interesting to see the results of performance...... Because we know we fly with lipo which is lithium polymer .... Then there is liFe batteries and then there is lithium ion and I want to say that they call them lie on ... And then there is a new style but very expensive lithium but it's mostly graphite and it's not our style of lithium graphene but similar you might find the research on TH-cam
high amper discharge lipo/li ion, i burnt the lipo one but they don't explode was it due to it had broken ones?, anyways at the 10:25 it's impossible 'cause an aa batteries Don't have any high discharge amper whatsoever
Could someone help me out, at the end when they were flying the 6” the motors were making a rough noise at a certain amount of throttle, my quad started to do the same thing with one of the motors, I don’t have a clue why. There’s no physical damage and the motors are all new.
Instead of 1.5V alkaline batteries you should use A23 12v Alkaline batteries. With 12volts and 23 amps and being half the size of een AA battery I bet it would work.
Just watching this video. FYI Non rechargeable batteries can be recharged but at a VERY VERY low power. They won't last and can only be charged a few times before completely dying. Obviously do this at your own risk.
I've tried all tips of batterys and you should of tried the Energizer batteries last loger not that you guys did anything wrong just my opinion on batteries great video guys
Using rechargeable AA batteries doesn't count. Good NIMH batteries can sustain much higher amp draws than Alkaline battries, although they are still leagues away from li-ion or even lipo batteries.
Alkaline batteries have an extremely high internal resistance. lipo batts have an internal resistance of around 5 mOhm to 20 mOhm. alkaline batteries have around 100mOhm or .1 ohm. BIG DIFFERENCE. Great video showing why we use LiPo batts... gg on the vid tho

Bardwell just sending it right at the very end was the best thing I’ve seen from RR in years. That’s the kind of off the cuff humor I love.
I had a lot of fun doing this! Working with the RR guys is always great, especially when they're convinced the task is basically impossible
Agree with Aakash 💯
Awesome stuff, man. Well done!
When Vanny says a battery might catch on fire... He overcharges all of his batteries too.
I never want that meme to die... because it's hilarious
You can charge a LiPo (4.2V) to LiHV (4.35V) voltage without any risk. The only thing is that the lifetime of the battery will shorten by a lot.
The reactions are so extreme, they almost appear fake. You're messing with double AA battery's, not the philosopher’s stone.
Dude perfect reactions lol
They used to fly helis off those nimh packs before lipo was a thing, so not very surprised
And rc cars, just you could not poke it with a sewing pin and almost light your house on fire (My Mistake)
This is actually an interesting demonstration of how much power these little lipos we use have. The energy density and discharge rate is incomparable.
04:55 Me looking at the deans connector and thinking: something wrong is not right

for those that dont remember the days of nicd and nimh know damn well we can use AA's in rc toys. lol the drone community acts like all this stuff if new uncharted territory.
Yeah but flying takes a lot more energy and power than rolling a car along the ground, drones never ran off of nimh
This is literally how I powered random electronics I was trying to mess with when I was like 8. I literally taped batteries together.
Basically it's the internal resistance that are sagging out the voltage as more current goes through the battery, basic physics, so this is why we used lipo cuz the internal resistance won't be taking out a lot of voltage in the process of discharging (ie internal resistance -> heat, that's why the bat pack got very hot)

I would have tried tethering it and flying it like an old school RC helicopter, like the one I remembered my grand dad flew back in the early 80’s a good 30 feet of wire hoooked up to a car battery.
Couldn’t you try this using a toothpick-style setup with an all in one flight controller/esc to save weight. Maybe a 1s 3 inch build
Love these episodes! 🔥🔥
Wouldn’t it have worked better if you used different motors and props that were designed to be super efficient?

Now you need to make a drone that will fly with solar panels only

ayy Sam's here! throwback to flying a TT lipo on 5in haha
11:22 what controller is that alex is holding
The video doesn't reveal it too clearly, but it might be an frsky x-lite.
Can you try it with 9v batteries next? there's are rectangular in shape, probably easier to mount and stack too.
😂🤣 that awesome!!
Would be cool if it worked same way as Lipos 😎
Bardwell at the end🤣🤣
the drone letsflyrc made for the batteries flies less because its using more power for the fpv signal, when the other one was LOS
Can a Drone fly with AA batteries?

Should be using like a rekon 5. Analog.. lower amp draw and we'd be able to see voltage and amp draw
