In this project we will be having a closer look at my vacuum. The problem is that its run time is roughly around 10 minutes and the worst part is that it takes 4 hours to charge up. So I will be showing you how I added an adapter to the vacuum which allows using Makita battery packs in order to power it. This way the battery run time becomes basically endlessly because I got 2 battery packs I can switch between. You can of course implement this Makita battery pack idea into other devices if you know what you are doing ;-) Let's get started!

great scott: shows that he owns, and uses a heat gun
also great scott, 30 seconds later: uses lighter to shrink heatshrink
Hahaha I thought the EXACT same thing as it happened!!
Ehh, I do the same thing, although I also don't have any sort of dedicated work area, so mine gets packed up for storage after every use.
ehh a lighter is faster and less bulky for couple of heatshrinks
@@araigumakiruno Yup, and applies heat more locally
*welds abs*
also: "i just used hotglue"
you can also hear the motor works considerably better with the external pack. Almost certainly because of less voltage sag (battery packs for tools are designed for current draws of 20amps and above)
Unless the motor also pulls more amps, aka it will die quicker if it's out of the motors' specs. If the design was expecting X voltage sag, they may have used a lower spec'ed motor, running without that sag it will draw more amps.
@@timwatterson8060 Well, technically not wrong, but I'd say that would be a rather crappy way to design a product, where the tiniest change in voltage will make the difference between it operating normally or dying, it isn't unusual to run a motor an extra volt or two higher and be perfectly fine, you can run them even higher than that as long as you're careful to avoid overheating it.
@@timwatterson8060 The motor will most likely die sooner, not just because of the increased current draw but because it most likely wasn't designed to keep working for longer than maybe 20-30 minutes at a time, with a couple of hours of break in between.
@@MikrySoft I wonder how long it takes him to hoover the lounge? 🤔
@@MikrySoft just put a fan on the motor fan bro
Thanks for doing this, it's what I have wanted to do for over a year using my Aldi 20V batteries. I was going to remove the original cells but was concerned the internal BMS would not allow the external power, you have given me the answer!
Glad I could help
Be careful. I have the batteries from Lidl and they DONT contain the switching electronics inside them. They only give you a voltage on the third pin which tells the tool to turn on or off the power. So the cells are literally directly connected to the output terminals without any kind of switch or regulator which means that it’s very easy to overdischarge them by using them with anything but the original powertools.
They recently brought new smart batteries to the market where you can monitor the current on your phone but those values also come from the pcb in the tool and not the battery. You can however take the pcb from one of their battery drills and use it in your adapter to monitor the cells
@@maxwfk Did you not watch the video? There is a battery control circuit inside the vacuum. It protects from over and undervoltage
@@maxwfk we must be using different batteries dude, I have the work zone batteries and I use them in a buggy that I built for my kid they always shut off when they reach around 5%.
I wish Aldi in the US was as cool as Aldi in the EU.
This was a great idea, I think every portable vacuum should have this. (:
Right?!
@@greatscottlab Bosch and Makita seem to have their own vacuum cleaners that use their batteries. Not sure how good they are though
@@efeyzee Everything that Makita makes is the best you can get. Anything made by another company is garbage. Makita for life.
@@haywoodyoudome lmao. Hilti
@@dimitrijekrstic7567 Hilti is great if you really need to spend the money to impress others. It's like overcompensating for having a small "tool".
Im so glad i bought the makita vacuum not these brands. I have Makita Dcl180Sw, they had a campaign where it came 100€ with a charger and a 2ah battery included. Ive been using it for 2 years and I feel the frustration others are facing with internal batteries. So many devices like shavers, trimmers and other tools have same issue but are still being sold. I wish companies would design more things with changeable 18650s cells
Modding household appliances is in my opinion one of the best challenges for DIYers, because you have to consider several factors such as compatibility, ergonomics, aesthetics and longevity of the modifications.
And yes, GreatScott! is good at this👍
@@maxhouseman3129 my wifi router needs a toaster, too😂
I've used one of those 20V battery packs to jumpstart my old chevy truck, I'm sure they can handle a little vacuum cleaner (granted the drill battery I used was smoking afterwards because of the high current draw, but when you're stranded on the side of the road and gotta be somewhere you gotta do what you gotta do!)
Didn't ElectroBOOM do it with AA batteries? lol
@@aliveandwellinisrael2507 yep
Dude... the battery is supposed to draw 20amps continuous, 30amps max....
And you drew 680+amps..... that's essentially a short to the battery....
@@1337GameDev Yep, that's why you get 7ft away and hope it works
@@linuxguy1199 That is why you connect it to your car battery and let it sit for a good 5-10 minutes and let it haste slowly 😀
Endless??
Electroboom didn't like that
I was expecting a free energy device as well 😜
I was honestly trying out different words as well.....but I just think endless sounds the best.
@@greatscottlab You should add "hand-held ray gun" to the title, as that is what this device looks like 🙂. You should add a secondary battery connector so you can do hot-swapping while vacuuming 👍. But I wonder if this consumer product is capable of long time continuous operation anyway. Could be that the motor needs cooling in-between.
"Unlimited" run time. Thermodynamics would like to have a chat with you. :)
The relay works, but also constantly drains the battery when it is connected. A better way to do this is with a MOSFET switch.
Haha yep. MOSFET should also work. Just need some more additional components.
So, I was listening to the dialog and heard “…the solution is of course…” and 100% expected the following words to be “a MOSFET” (or two). Then, the _relay_ popped into view. What!? But, I suppose it makes sense, in that it’s an easy project for beginners, and this is an educational channel. Personally, I would’ve added something like a red LED as a little reminder that the battery pack is still drawing power, even when the vacuum switch is off - reminding the user to remove the pack. Overall, it’s another nicely made video. Thanks.
Hey, The Signal Path is in da house :-) Power consumption of the relay was my first thought as well, but these days, you have to use what's available...
@@greatscottlab Of course this was not a criticism. I know that you know. It was more meant for a viewer who may not realize.
I have a similar vacuum from Electrolux, but I must say that the inners this Bosch are much nicer. The Electrolux unit is not easy to disassemble and a huge pain to repair!
I bought my mom one of the Electrolux stick/hand vac for Xmas a few years back, Sadly I think she tossed the brush retainer piece while cleaning it and I couldn't find that piece as a replacement part :(
I also have an older model of Electrolux that I have need thinking about swapping the batteries on. After watching this video I'm thinking about skipping the internal batteries and go for external pack.
Huge thanks Scott! Amazing videos as usual!
I might have the same one. I was impressed he got 10 minutes, my Electrolux probably lasts 4 at this point.
@@bunnygirls556 - Do you like vacuums, Sexy Time Bot? I do - suck and blow... Tell me about your experiences, Sexy Time Bot!? 🤣🤣🤣
Love this! I've considered doing this to a few things of my own. I did it with a car battery and a UPS to give me a huge emergency power bank a while back for while I'm out fishing lol
Plastic welding, something I've never thought would exist. You have given me a new tool in my tinkering repertoire thank you!
The plastic welding is nice - thanks for this. Nice project - keep it up.
Thanks, will do!
I upgraded my AEG 2in1 vac(exact system which is shown in the video) with 3500mah 18650 cells. Works perfectly fine for 25 min of constant vacuuming without the cells being discharged completely.
Great videos, I did electronics and computer maintenance and repairs in college for about 5 years, I'm still learning your videos are a great learning tool.
Absolutely Massive!!! I have wanted to use the same concept with power tool battery packs on other devices but I personally lack the expertise to work on such projects confidently. Seeing how you have done this project though gives me an easier path to follow conceptually. Thank you! I've been a long time watcher and study in my spare time. This video was massive for me!
The batteries for these rechargeable devices seem to age faster/more than a simple capacity test suggests. I wondered if the issue was an increase in the internal resistance such that voltage falls faster in use with a high (7.5a) discharge current ?
That is more prominent with older NIMH or NICAD batteries. Those have something called memory loss (if my memory is correct lol), but Li-ion don't have this or atleast not to such a degree.
The aging is maybe caused by keeping them fully charged at 4.2V constantly - LiIon cells hate that. Better if they charge up to 4.1V then stop and let them settle, then charge again when the voltage drops below 4V or something and repeat. If you know you're not going to use it for a while, then discharge the battery about halfway and check it again in a few month''s time.
Beyond having to pay attention to safety, battery manufacturers care less about cell longevity, as it means they can sell more packs sooner.
With care, these packs could last 10 or more years.
The cells degrade when they have a high current draw, li-ion wasn't best known for this like lead and a few other types as this can make them heat, or you get evaporation.
If you had a better match (current availability to capacity) then the battery should last longer retaining its capacity.
As you got another reply, charging the battery to 4.2 isn't great. 4.1 gives you more cycles. And for long term storage 3.7 volts is desirable as the balance of electron's keeps the battery in better order. But all batteries are the same in that respect.
Nicad, has a memory effect, so if you keep them low they want to go low, or they can shallow cycle and all sorts of fun. These are best left discharged and charged when you want to use them. They don't have Ill effects. Trying to keep them normal is a problem. As they have a high self discharge
@@guywhoknows leaving NiCads discharged in storage is a sure way to loose them to dendrite formation (internal short circuit).
And Li-ion can and will repeatedly do high discharge currents, you just have to pay for the cells that are actually designed for it. Power tool cells like those in the Makita pack can easily do 8-10C from full to zero charge, the only limit is the temperature. And they cost well over $5/pcs even in bulk.
@@AKAtheA Makita batteries aren't good. Mine all died and were kept well, they have little electrolyte.
This is actually a good idea. I wonder if the vacuum cleaner shuts off if the makita battery pack voltage gets too low to prevent overdischarge.
I didn't catch whether the relay will shut off when the battery gets too low... I don't even know what 'too low' is for a battery pack.
Battery pack probably will cut off ? ....
You're actually leveling up so well!
Your knowledge and skills have always been highly respected, practical application is key, great job.
Pretty clever. Instead of using a relay, I wonder if it would have been possible to mount a switch inside the battery adapter that would be physically actuated when the battery is inserted.
What happens if you try to charge your vacuum while the Makita battery pack is still attached? Wouldnt that be dangerous because it will charge endlessly ?
My reaction to not being able to vacuum because the battery is dead, is a very sarcastic "oh noooo." That said, I do appreciate your effort here!
Haha for me it is a big deal though ;-)
Been subscribed to your channel for years, great to see you for the first time.
Proprietary battery packs are a scourge of humanity. As with USB, there should be a standard interface for battery packs between manufacturers, and royalty free.
How many of us have various power tools over the years and have boxes of different packs and chargers?
Some of them have become unusable as tools wear out and the packs become incompatible with later models or other manufacturers tools.
I fully agree but I guess that will not happen unless they are forced to do it (looking at phone connectors)
@@Luke-san Absolutely - they had enough time to get together and figure this one out on their own.
Finally someone else with the same love for Makita batteries.
I recently built an adapter with an arduino, to output 8v to my canon dslr. (QC3Control)
Pretty much infinite shooting time, in the night! :D
It also has a few QC3.0 USB Ports for fast charging and optional equipment like a lens heater.
Do you happen to have this posted somewhere? Sounds pretty dope, love to have a look at what you built! :)
Why Makita batteries specifically? Are they somehow better than other batteries of this type or is it just because Makita are the only brand you've bought and you're happy with them so haven't tried others?
Excellent video Scott, thanks for your persistence!
I watch your videos for the diagrams you make, they're easily understandable even for someone like in another field. Good video as always.
What i realized from this video is get a plastic welder for easier integration with custom components. 3D printing takes a heck lot of time.
Just a heat gun and some abs sticks. Pretty cheap ;-)
@@greatscottlab or soldering iron, ABS filament, or chop up used laptop battery cases into strips etc. Seems that ABS is everywhere once you know what to look for!
Can it glue pla to abs?
It's weird that portable vacuum cleaners don't already have interchangable batteries like other cordless tools. Nice upgrade!
That makers of these battery tools actually make vacuums, too, and they use their respective system. So it does exist.
I did this exact mod over a year ago to my dyson using the same Makita batteries and it still works works to this day.
You are a genius dude, sell the idea to manufacture it is really worth. Needless to mention you are a great designer with things, i always like your details in your designs
I coincidentally retrofitted my two old NiCd battery power drills using that same Makita battery adapter not that long ago. The NiCd batteries were worn out and there were no replacements to find anymore, while the drills themselves both worked still fine. Using this 'hack' I now have given my two drills a new life.
Lovely :-)
I've done the same to my old tools.
I'm going to do the same with a pole saw that's got a NiCd battery and missing charger.
Note to self - test pole saw motor tomorrow 🤣
@@tin2001 if it is just similar in voltage it will work (assuming you are using Makita or other decent batteries with built in protection). My simplest was attach the wires from the adapter straight to the old battery connection pins - 50+ hours of use and no problems yet.
First, I appreciate your choice of going with well-known and trusted brand for tools, such as Makita and Bosch. Second: ABS plastic welding is awesome, never heard of it
I've had two Bosch vacuum cleaners. As a result of that, I will never buy a Bosch vacuum cleaner again. I thought the first one being a PoS may have been just an accident. Nope.
@@RFC-3514 make sure you're not referring to general purpose Bosch tools. They are not cheap yet standard to low quality.
Bosch professional equipment is coloured with a different grade of green. This kind of drills is, for example, at the level of Makita, Milwaukee, etc.
It could also be that Bosch is not specialized in vacuums (Karcher would be better)
@@matteol.7311 - The Bosch vacuums I used (like the one in this video) are not classified as "power tools", and are neither green (consumer) nor blue (professional).
Bosch blue line tools are generally decent (as are some green ones), but I'd still rate them slightly below Hilti, Mafell, Festool, or even Metabo. The smart thing to do (money wise) is to find a tool designed and made by one of those (or by Elu) and now sold under a different brand. For example, Metabo sells some cordless drills which are actually Mafells, and DeWalt sells a sander that is actually a Mafell and a couple of routers that were originally designed by Elu. Most of DeWalt's new stuff is kind of crappy.
I have a couple of Kärcher pressure washers (mixed results; they get the job done but some of their plastic parts break very easily - namely the filters), never tried their vacuums.
That one was awesome. I love modding out everyday things to make them better.
I love that "I can combine these two things by just rotating one slightly and pressing them together" bit sooooo much. An oldie but a goodie
Nice done! What is the consumption of the relè coil continuously draining power while external battery is plugged in? Is it negligible?
Yep. In comparison to the motor current it does not matter. But you have to unplug the battery pack when not being used. Otherwise the relay will drain it.
@@greatscottlab What if you switched the relay through a transistor from the vacuums switch, since they are sharing the same ground anyway. Then if you leave the Makita battery plugged it, it won't get drained below 15v.
Nice, great idea that i will do on other devices. Question though, did you notice a shift in the center of gravity of the Vacuum? If so, does it become annoying when the external battery is installed?
@@maxhouseman3129 sure, but the question is, is the shift noticeable?
Those Makita battery adapters are amazing, they saved several of my older cordless tools from being scrapped, plus now i can use the same Makita battery for all my cordless tools
I have the Makita cannister vac that uses that battery. It changed my life. My home has never been cleaner. It's so fun to use.
I think it would be good to make a video in more depth describing ground issues, like mentioned in this video having 2 separate power supplies isolated. And fixes for this and how it happens
Great video. That said, would like to also see a video exploring the idea of replacing/upgrading the vacuum's original cells, with the highest capacity cells possible(!)
Well that one is just too easy 😉 and would take even longer to charge...
@@rpavlik1 He could have checked how much the charger could theoretically pull and then upsized the PSU to one with fitting amps
The irony of connecting a Makita pack to a "We have an open battery program" Bosch Tool, really does it for me. Nicely done!
I really like your channel due to the modifications you do to everyday items to make them run better or more efficiently, imagine how many of these vacuum cleaners get thrown out because of the internal battery packs dying. love your work, keep up the good job :)
Honestly I wish more products like these would use either exchangeable batteries with larger capacity options or have a battery add-on like this.
I kind of wish laptops could use tool batteries...
You can charge laptops using these now. There are usb-c adapters for some makes of batteries.
I looked into this problem some time ago. And as I'm just as you addicted to Makita tools, I bought cordless Makita vacuum cleaner. It would be great if we could develop interchangeable battery adapters so we can power everything with Makita batteries. Good video. Thanks.
If you got access to a 3d printer, there are already hundreds of adapters for many different tool makers. Got a makita tool and a dewalt battery? There is a file for that. And vice versa.
Thanks from Texas Scott
Didn't know about those battery adapters. Solved an issue for me. Thanks.
that is defiantly interesting! Was it just me though, or did it sound like the motor spun faster with the external battery? maybe able to pull more power? or was it just due to different states of charge.
Yep, defiantly.
I have almost the same Vacuum and I wouldn't mind a bit more power.
Yep big difference indeed
Awesome idea of reverse engineering on home appliance ✌🏻✌🏻✌🏻
Loved it 👍🏻👍🏻👍🏻
Thank you! Cheers!
@@greatscottlab Keep it up 🙏🏻🙏🏻🙏🏻
Oh man, this project gave me a lot of ideias!
Thank you.
Very interesting video!
I really loved the part where you disassembled the vacuum and explained how it works.
Tolle Idee! I have one from Bosch that already uses the 18v batteries. The upgrade I would do to mines would be to make an adapter to have it connectable to 240v and use it as a "cable vacuum cleaner" just for those days when all batteries are at 0%
I would highly recommend a variable AC-DC power transformer serial # HJS-480-0-48 as it's very well built, has a digital screen displaying DC voltage, and can do 0-48 volts.
@@ProlificInvention thanks! I have to see how much current it can output at 20v and how much current (or actually power) my vacuum cleaner needs
I don't see an issue with pulling out the cord of a vacuum cleaner and putting it into the wall. Never having to worry about batteries running out, and a corded vacuum cleaner is way stronger and has more garbage storage capacity.
@@Engineer9736 indeed! But if the batteries are loaded, it's a very comfortable thing!
That's legit! 💯 Awsome job. I love the plastic welding 😂. I didn't even know you could do that.
Now you know ;-)
Amazingly simple, clever, and very useful. Great video.
I love this idea. Creative solutions to common problems.
Love the idea of the extra run time. The only issue I see is the side mount makes it unbalanced, which could be hard on a wrist.
That occurred to me also and I thought he would put one on each side to balance it.
Have you considered bulking up your delicate wrists?
@@lescoe "And this is how cordless vacuuming became a new Olympic sport"
put anonther battery on the other side xD
You should now upgrade the motor to a BLDC, so you will have more powerful vaccum !
It would big suck
Sounds like fun :-)
Battery adapter plates are awesome! I always wanted that now to try to remember what for
Thanks for the bit about plastic welding! I'd heard of it, but never seen it before now. 👍️
I think nowadays you're getting out of your shell and trying to do some clickbaits 😂 a proper Example of this stereotype would be today's thumbnail and title [also looks promising!] . anyways I like your videos. Keep the spirit up Mr. Scott 😉
I hope to reach more people with knowledge content ;-)
1:53 insert german stereotype here 😂
And put "I Want to Break Free" by Queen under it.
Cool project! Have done similar with other tools and 3d printing. I found the fact that Makita literally make this product as a skin amusing.
one of your best projects ever!
Very nice modification! The horrifying part though is how much dust gets through that bag filter and into the air.
I'm curious about the ergonomics of this mod. It's nice to have longer battery life but can you hold it for that period of time with the added weight?
i dont think his hand is going to explode from an extra 3lbs of weight.
I don't think that weight is a problem but bigger issue is how to mount battery holder so it would look good. To keep it as light as possible then option is to remove original battery and use only outside one. This would be easier mod to do anyway.
I'd be less concerned about the weight itself and more about the fact that it's only on one side. It would have been great if there was a way to mount the battery on top since it couldn't go on the bottom.
Amazing video as always! Great work
Nice! I also converted my old Rowenta vacuum with Ryobi batteries and it's so easy to use now!
I feel like it's easier to just use a vacuum that plugs in to the mains. I mean, yeah, it's nice to have a battery-powered, portable vacuum that is highly mobile, especially once you've modded it to take portable tooling power packs, but wouldn't a power cord be so much easier inside of the home?
moving a cord around is a pain in the ass. if you used the same battery pack for multiple things there's a higher chance you'll always have one at 100%. extra weight might be harder on the arms though, i don't know since i don't have a cordless.
Mains cords are bothersome. The vacuum needs to be move and moved, up, down, all around. The cord is ALWAYS in the way.
Yeah, but then we wouldn’t have another GreatScott video…
I’m usually on team Power Cord too, btw. Recently, I went to use my cordless drill and discovered that it was more discharged than I recalled. Fail. So, I grabbed a corded one instead. Guess what? It worked right away.
That was German as kraut... I liked it!
Brilliant ;-)

Excellent video, i often thought about doing this to my flimsy dyson, brilliant presentation and explanation
Agreed, everyting should have this! Although I'd rather build around hoverboard batteries, you can get the chinese ones for really cheap
Sure. But the Makita stuff is pretty much standardized. That makes it easy to use for everyone ;-)
Cheap chinese batteries are the ideal solution - if you need your house burned down real quick.
@@greatscottlab …yepper, ready-made packs, with standard connectors, and ready-made chargers. What’s not to love?
@@andreasu.3546 Not anymore. Now reputable OEM cells are sold from China too. Might be due to increasing EV prevalence in China.
@@andreasu.3546 @Faust Von Barley is right, you can actually get decent battery packs from china for a fraction of what makita costs, or get even cheaper ones and make them safe yourself.
Tho even if you were right that'd be a cool way to get insurance money
A few months ago I bought the 18V cordless Makita vacuum. It sucks, I love it
Good stuff! Hacks like this are really fun. They definitely spark creativity for me.
Awesome! I'm looking at the exact same external Makita connector right now that I've had for a few months and not needed yet.
I was thinking I would probably cut out the back of the "transformer mode" full size and just deal with the ugly hole, to mount the batter on the bottom. Then you introduced me to plastic welding and now I know I would have.
This is great little project. Thankyou!
I use semi similar configuration on my black&decker vacuum. I used small voltage regulator from battery to balancing wires for tricking them with 4 volts.(I removed old18650's) Works like a charm.
Scott if you haven't watched Tools & Stuff yet, he's your guy. Great Makita tool reviews from New Zealand.
Nice dude. Top notch job.
