Scott, you have to be one of my favorite content creators here on YT. I have to admit, I try and not watch your video as soon as you upload them because I like to watch them back to back, and this home remodel has been so entertaining and inspirational. You guys always manage to motivate me out of a "maker hump." Just this morning I watched your backlog of videos since you got back from your break and was feeling kinda blue knowing I wouldn't have anything else new to watch and BOOM new video -- good timing! Thanks for all that you guys do, keep it up!

[@christophemanger607]

First of all big respect to you and Ray for doing this job in that fashion. It really looks like you either need tons of Batteries and chargers to get such heavy duty jobs done or go corded/ Fueled. I was really impressed how the Milwaukee held up despite beeing one 18V Batterie. I would've probably just stopped and go borrow a corded machine after the first day :) Love your videos, greetings from Germany

[@LazyCrazyGuy]

Speaking on Milwaukee but I'm sure this applies to the majority of tools including Hilti. The Supercharger can charge a 12ah battery in about 60 min but if you read the manual you'll notice it says that when the green light goes steady it means it's charged at 80% and ready to use. If you understand fast chargers and lithium ion technology. You'll know that they prefer to stay charged between 40% and 70%. Keeping them within these parameters gives the battery it's full potential of lifespan. Now I know this isn't ideal and especially when you need to get work done but hear me out. Fast chargers usually charge from 1% to about 50% at the fast rate at which point it slows down to a normal rate. When the battery reaches about 80% - 90% it will slow down to a slow charge rate. Which means if you can just use a timer and set it up for half the time or less you have less down time as the second half of battery charge slows down significantly and that is where all the wasted time is. If I were you I would just charge to 70% - 80% and use it up instead of waiting for it to charge fully at the very slow rate and decreasing battery lifespan as it doesn't like being fully charged anyways.

[@MichaelArthur4eva]

Would love to see some of the safety gear (masks) covered off. Gear like thst is underrated and we kiwis often DIY without or incorrect gear. Would be worth a mention of the toxicity of breathing in concrete dust. Another great video, thanks Scott

[@sematagi9291]

great episode, I find using the pointed chisel heads more effective when breaking up concrete, less resistance than the flat heads... mind you, its still hard work.

[@dengshomeinvasions1273]

Drilling a hole and then using a flat head or pointed chisel works even better.

[@bearhauscubly]

Great video, I've used the Milwaukee MX equivelant concrete saw and had the same results with battery life. I think the most useful application right now is taking door interior walls in countries with masonry builds (like here in the UK) where the fumes from a petrol saw would be unsafe/unpleasant. We are just not there yet for it to be practical.

[@samsboringchannel]

Definitely get the digger next time! Even when it comes to loading out, a digger and small tipper for half the day will make light work of that pile down to Fulton hogan! Great to see where we're at in the evolution of tools, but agree this heavy duty stuff needs more development. Watched a video recently of a small electric excavator, 2 hour run time, then 8 hours to charge! Chur!

[@mrpoopypants9586]

Ahh, old builders. Fill everything with concrete, use hardwood framing that will burn your drillbits out, make sure no two pieces of timber in the house are the same or standard sizes and bury old bricks throughout the yard. Oh, and don't forget the vertigo staring down the hallway where no wall line is plumb! Well, that's my place, anyway. Love seeing the real world reno. Cheers from across the ditch. Cheers PP

[@juliocervantes7125]

I recently grabbed the cut off saw with 4 batteries and 2 chargers for a basement remodel. I cut about 60 linear feet with 4 fully charged batteries. It did the job and half the hassle. My cost was ~2k for the entire setup. I really enjoyed using the tool and most importantly make me $$$ Next buy… Nuron Rotary Hammer…. 🤔

[@ptortore]

I like your music choices Scott. Much easier to watch than some channels which insist on heavy metal or excessive beats to accompany their vids. Keep up the good work!

[@gordonclark7632]

Well, the first thing i did was go outside and look everywhere for some tools and realized that I was the tool expecting to find some. Other than that, I think that this exciting episode showed that there is still plenty of things that a powered tool can do better. One thing that I thought of was the cost efficiency of using a battery powered tool for the job where the cost of all the batteries needed and then the cost of the charges and finally the cost of the electricity to charge them could exceed the cost of just using (or hiring) a specific tool from a hire depot?

[@JBrizzle99]

Full credit to you for persisting with those stairs while the Japanese were launching their air attack, that's dedication!

[@AyeTheKay]

5 year experience in demolition and concrete cutting. Could have done that job without the concrete cutters and just used the big jackhammer. Corded would be better. Have got the dewalt but not as big as that Hilti. Get about 10-15min out of a single 40v. Corded is the way to go with jacks. Great content. Keep it coming

[@RFC3514]

I think the point was to show off / test the various Nuron tools. I'm pretty sure they didn't actually buy them.

[@timwillmot4941]

This is why I like the Hikoki system as if you are doing a big job like this you can plug your battery tools in with the AC adapter and use them all day but if your out on the farm or just need to do a small task you can just whip out a battery. You only need the one tool. also there is a 21 Amp battery back pack made for the garden equipment that is awesome for this kind of thing. or you can hook it over your dropwsaw stand and it will last you days. They do have a bigish breaker but no concrete saw yet. I'm keen to see the new tracksaw in action can you ask Gaston to get his hands on one from Accent and do a review?

[@holbroak]

I love the combination of ballet music with concrete breaking. I've done concrete breaking in the heat of summer, in the bottom of a 5 metre-deep sewage treatment trough. Still preferred it to dancing figures 😵

[@Homelifenz]

Wholly molly that's a serious load of battery use. Hubby spent hours doing our chimney concrete slab and a huge concrete slab on back section when we moved here 16 yrs ago. Hard physical work

[@eduardocarvalho1547]

Wish I could find Easter eggs like that!🤩

[@sniperfi4532]

As much as I like the idea of having me battery to suit all tools I think larger/high demand tools really need a specialised battery. You made the correct point of needing 4 chargers and 6 batteries to be able to run the tools constantly. It just seems that you need to spend as much on batteries and chargers as you do on the skin.

[@JDAfrica]

Milwaulkee has a specialist flat battery panel for their breaker/jackhammer - I wonder how it would compare

[@marB84]

Wow! Much respect for both of you. I wouldn't use battery-powered tools for such a job to begin with and you saw it through. Well done!

Yep gas saws are still the way to go. :) NZ must have small dump trucks, that would only fill a trailer in Canada. :) Thank you and have a good week.

Scott, there is a liquid you can buy and you mix it with water and pour it into drilled holes. You cap off the holes and the liquid expands, even cracking concrete. It's a start, at least!

My apprentice recently decided to splash half his wages on a hilti impact, battery and charger. I've gotta say I was really impressed with how the batteries fit into tools after whining about my milwaukee ones for the past 4 years

[@JerryPonds]

Milwaukee literally has the worst fitting battery of all time. You should try makita, I use their 18v system and the batteries are super smooth.

[@HotForgeChaos]

@@JerryPonds Yeah I'm not stoked at how much of a pain it is to remove an M18 battery compared to, well, everything else. However if you're noticing your battery flop about like a Kingfish in some of your tools, do not worry, that is by design

[@JerryPonds]

@HotForgeChaos really cool. My makita tools have silicon inserts in the battery part to prevent the batteries from flopping around.

[@Frieslick]

They’re designed to “flop around” to prevent vibration damaging the cells bud. The batteries should only really fit rigidly into non vibrating tools like torches/radios/heat guns etc.

[@frankryan2505]

​@@devilselbowMakita gear has the battery wobble too (rotary drill/recipros)

[@douglasvoon9981]

I think that job would have finished me off! The battery issue you guys had reminded me of my gripe with a certain Makita 36v lawnmower that I purchased. I spend more time charging than mowing and it's been in for repair 3 times under warranty so far as it kept overheating. Scott's comment about the early days of battery tools seems to apply here as well. In a few years I'm sure the battery powered mowers will be awesome!

[@paulzirker706]

That looked hard work. Well done Scott.

[@caveweta]

You needed a bin to tip that rubble straight into, lots of double handling now to clean up the drive.

[@Sam0n1]

100% agree. The big boy toys. Cutters, breakers, lawn mowers are still not there. You just can't beat the petrol or corded options there yet. Think I felt the pain when you have batteries going flat and just want to get it done.

[@perrymaxwell4488]

As a person who has had to chip enormous quantities of concrete by handheld battery, air, and chorded tool, my advice would be to skip the cutting on the stairs. People also like to drill multiple swiss cheese holes with a rotary bit too. It's all taking away from your time to chip and doesn't offer a net gain in time. You have 3 open sides for the concrete to chip away from the original mass which is ideal. For the slab, I'm sure that concrete didn't like cracking when you slammed it with the sledge, so multiple scores were probably necessary to help it along. However in newer concrete, once you have a section (channel) removed end to end, cracking with the hammer is way faster than chipping or scoring when it's less than a 6" slab. Also, and I understand there are probably constraints as to what was available to you having borrowed that set up, but a chipping bit with more of a point and less of a chisel would increase your productivity due to less surface area being driven into the concrete. Especially against that old stuff I'm sure that bit was nubby by the end of that project. One upside to charging the batteries is that it gives the bit time to rest and not overheat and snap. Obviously more productive to have multiple bits to swap in and out like a SAW gunners barrel. I had a few endless days of using bushing bits to remove an epoxy coating form a concrete slab, and I would snap multiple bits a day. Luckily I wasn't paying for them😂

I’ve always considered Hilti to be at the very top end of electric work tools. In some cases even better than Festool. Expensive but top quality. My opinion hasn’t changed.

In pretty much all cases, for construction (and demolition). Festool's main focus is woodworking.

I have the makita concrete saw, takes 2 x 18v … it cuts 6m on 5ah batteries, 90mm deep. You need plenty batteries to work with it - but luckily I have like 10 batteries so never a problem. Nice to see real actual usage on the hilti stuff. That jackhammer looks super - but, I wonder if hiring an electric one is better value.

[@frankandrews58]

[@FeelingLikeThatNow]

The batteries will take longer to go from 80-100 than they do 20-80, so the best practice is to keep them in the middle of their chemistry sweet spot by battery swapping to recharge up to that 80% again, and using them without fully charging.

[@hw2508]

Its better to use them from 80% to 20% than from 100 to 0. Saves time at the charger and is better over the lifespan of the battery. However, I think most people always charge to 100% and run it as long as possible. And I would include myself in this group. It is not easy to change old habits.

[@jonathonalsop2120]

Batteries should have a mode button to switch from 100%-0% and 80%-20% and default to the latter, while always leaving a buffer that can't be accessed. I'm sure many companies do have big buffers but it's not standardized.

[@HotForgeChaos]

Sometimes they want to be run right down though, I found my Milwaukee batteries are a bit happier once they've been run right down and charged right back up every now and then

[@FeelingLikeThatNow]

@@HotForgeChaos yeah I can see how that might happen too, since these multi cell batteries have pretty complicated control circuitry and it might calibrate the way it charges all by itself.

[@TonyRule]

@@HotForgeChaos I think that's placebo effect. You used to actually have to with NiCad because they have 'memory' but NiMH and the various flavours of lithium do not.

Great video Scott, I myself removed a set of stairs exactly the same as your ones using a similar method using a powered Hilti breaker and a petrol Stihl concrete saw and boy it was still hard work! After watching this I think if you had a powered breaker and a petrol concrete saw it would have made a huge difference but glad you showed a true representation of where the cordless tools are at right now and your right one day, they will improve to the point of being on par or better than the powered versions. But at the end of the day, I said the same thing too.. next time I'm getting a bloody digger!

When I was looking for an 18v sds, I looked at all the big brands, inc, milwaukee, makita, dewalt, hilti etc, but the most powerful one I could find was the Bosch bi turbo 18v sds plus, 5.8 joules, use with either an 8 or 12 Ah battery to get full power, brilliant bit of kit, if I ever need a heavy breaker, I just hire one, but I think in your case, I'd go for a digger and dumper.

[@KermyGermy]

One of your best edits yet. 👍🏻

[@andrew5792]

Firstly, hats off to the pair of you for sticking with breaking that out by hand. Personally I'd have caved early and called in a digger. I'm going to disagree with your comparison with early cordless tools and where large format cordless tools are now. The first generation of cordless tools where using Ni-Cd batteries (much lower energy density), inefficient motors and no power management. The current generation are benefiting from about 40 years of development, Li-ion batteries, efficient brushless motors and onboard power management. You can make improvements by increasing the battery format as has occurred with 36 and 40 Volt systems, but the fact is that with any batter chemistry type there is a max rate at which a battery of a given Amp rating can be charged. Even if you build a more powerful charger, the practical charge rate will not change. A bit off topic, but this is also an issue with EV's. There are EV chargers available with very high Amp rates, but the vehicle batteries have a max rate at which they can be charged and this is what dictates how long it is going to take. Personal opinion, either there needs to be a very large capacity batter which is on a trolley/cart which can be charged overnight and then last for a whole work day (would be very expensive and defeats the 'cordless' part), or just stick with a traditional breaker/concrete saw and a generator. The reality is that the amount of money spent on the cordless option is not worth the expense in my opinion.

[@duncanmarshall241]

It’d be really interesting to know why combination cordless and corded tools can’t be made…for instance how you can use your phone or camera while plugged in and charging. Thanks for your vid’s 👍

[@MadLadCustoms]

They won't be able to sell you batteries then 😄

[@CallsignMiller]

festool tried it (i dont know if they still sell the adapter) with the cordless sanders. But the adapter cost as much as 2 batteries pretty much at the time i looked into it.

[@alip011]

Ego have a corded adapter for their outdoor range.

[@okafka5446]

They can - see above - Hikoki have a battery/mains adaptor - and see below - Festool have a battery/mains adaptor for their 18v sanders. The more trades that draw attention to this (and vote with their feet, switching platforms) the more other tool companies will introduce the technology. A You Tube video like this, by a poster with this size of following - is great for clearly illustrating the real world drawbacks of certain cordless platforms. All credit to Scott and Ray. 🙂

[@RFC3514]

They can, but for tools with a high power draw you need a pretty big adapter, that would make the tool significantly heavier. The alternative would be to have an _external_ power adapter (outputting 22 volts), but then you'd need a really beefy cord, because the current needs to go up (since it's only 22 volts instead of 230). Phones and cameras draw a very small fraction of the power that these tools do.

[@christopherinteriors6521]

I do highly rate Hilti. Hilti and Mafell are in such another class though that even most Festool owners wouldn't buy them. They are far too specialist for most people. Personally I don't think certain tools need to be battery tools, especially those which are hooked up via a hose anyway for dust collection or water.

[@Tyler1169]

always felt like the push from tool manufacturers to put their whole catalogue to cordless is more so they can market "largest battery platform on the market!!! we even made a cordless coffee mug check mate dewalt!" despite the practicality and how pointless having some of these tool on battery are. like look at the mafell jig saw, thing is the best jig saw you can get your hands on and is only corded.

[@scottmenhennet9933]

Eventually small combustion engines will be banned for import and manufacture at least in Western countries trying to reach net zero emissions, so manufacturers know they have to go in this direction for situations where access to AC power isn't available. They've gotta start some time.. Milwaukee MX FUEL range 72v battery tools are probably much more up to this job, and Makita's 40vx2 demolition saw If the fastest production car in the world can be a Tesla battery powered sedan, then eventually they will get heavy duty portable tools right too. Other companies already do battery ride on mowers and electric tractors.

When taking up a concrete driveway or pathway that's not reinforced with wire or rebar I've made quick work with a floor jack and 5lb sledg.

I would agree that some of the larger cordless tools just don't have the long run time because of the battery power they require, I would also point out that in all the 45 plus years I have done construction I have never seen anyone cut slots in a set of steps to demo them. Hilti makes some of the best cordless tools on the market,with the possible exception of this concrete breaker and concrete saw.. Also the use of the hilti breaker as demonstrated showed that both of you had not had much experience with the tool and how best to use it to maximize the tools capabilities. That being said I would never have tried to perform this demo with cordless tools. Hilti's corded concrete breaker would have gone through those steps like butter. you worked yourselves needlessly hard when the objective should be to work smarter,not harder. Keep on trucking on

I rented a quick cut to cut 7 20"×20" holes in 6" thick concrete. The rental company gave me a cordless Hilti with 4 batteries. I had to wait to charge 2 more batteries to finish all the cuts. It's just not quite there for a lot of cutting, more for quick one-off jobs.

[@geuzeg]

@13:08 My personal golden rule for batteries, they have to charge at least as fast as they last. So i'd only consider going cordless unless you can charge 2 12Ah's within 25 minutes. That being said, there is a weight penalty as well, which is another reason for me to stay corded on these kind of jobs

[@jvanmil6]

Ring saw job that one! would of hardly had to touch a jack hammer! Good effort for sticking it out though

[@theVoyage]

The issue of drawing down batteries faster than you can charge them is something you run into with drilling large diameter holes in concrete, I've gone through two and a half 18AH batteries to drill one 25mm hole before. I now have a mains powered concrete drill as well.

Many thank’s and a big shout out from Northern Ireland

Happy Easter to you and Jess...

I wish I had a Ray he keeps turning up and getting shit done

[@johnrabidou604]

love the videos scott. i would love them to be a bit longer. :)

[@technomyke]

I have some sidewalk I've wanted to knock out for a couple years. After watching this I'll procrastinate a few more years :P

[@klmbuilders5385]

Scott, I agree the bigger tool battery platforms are in their infancy. I'm waiting for a cordless battery driven auger that will turn a 12" diameter bit!

Seen the Makita auger? 36v - looks real nice

[@The2wanderers]

Whether you get 44v with 2 batteries or not depends on the wiring. If they're wired in series, you add the voltage. They can also be wired in parallel, which gives you the same voltage as one battery, but you get longer battery life than a single battery.

[@TonyRule]

You get the same battery 'life' (energy) either way because the Wh rating (Joules) is the same. But by going higher voltage with series you can just use smaller conductors.

[@The2wanderers]

@@TonyRule Yes, I didn't explain that very well. I was trying to say that longer life is the only advantage to two in parallel, while longer life and higher voltage will both happen if they're in series.

[@TonyRule]

@@The2wanderers Ah, right. I see someone below said they believe it's actually a 22V device, so it could presumably be run with one battery for half the endurance. So no conductor savings anyway in this case, just the convenience of only needing a single battery if you have a small job to do.

[@theunknownunknowns256]

Be cool to see a follow-up doing something similar with an eletric digger. Places in Europe use electric earthworks machinery in urban areas because of the lower noise levels means they can work them for longer hours.

[@RFC3514]

That looked like a job for a diamond wire saw like the ones they use in quarries. Two cuts and you're (practically) done. Of course, then you have the problem of moving a massive block of concrete, but maybe you could use it as a pedestal for a statue.

[@daylen577]

I'm all for cordless tools, but it seems to me like concrete hammers and saws aren't really the right target yet. Those are endurance tools that also still need a lot of power. If we ever get to the point where they can do maybe an hour on a charge that'd be great, until then I'd probably use a corded version instead

[@scottmenhennet9933]

Milwaukee has MX Fuel 72v range and Makita does 80v tools, I have the makita 80v rotary hammer drill and although the concrete I was cutting wasn't anywhere as much as this, it was pretty capable to use as a jackhammer

[@daylen577]

@@scottmenhennet9933 I never said they're not capable, it's just that the batteries don't last an entire day. Swapping batteries once or twice during the day would still be fine, but when you're doing an entire day of demo work you want your batteries to last at least as long as they need to charge back to full..

[@sniperfi4532]

@@scottmenhennet9933yeah I think they’re better off having two seperate battery platforms rather than trying to use the same platform for everything. Dual battery systems are ok but you really need dual chargers and 4 batteries to really make it worth it.

[@RFC3514]

What would be the advantage of going for one hour on a charge? You'd just need heavier batteries (or more of them). Surely you can take a 10-second break every 25 minutes to swap the batteries. Of course, a corded tool would be even lighter, so it's still preferable whenever possible.

[@badopinion]

Done a few stoops and found an 80lb jackhammer and with a tow behind compressor is the way to go. Can rent the combo for $350usd a day. I love Hilti tools though!!

[@Peterdecz]

Hi Scott, exciting video as always. What was it that you drank at the end? Cheers

[@kurtzcol]

the music was a nice fitting touch on this one

[@ArthurDentZaphodBeeb]

Those steps were a perfect place for expanding demolition grout - just drill some slightly angled holes about every foot, mix up the expanding grout, load the holes. Come back in the morning and that concrete would have been cracked to bits.

[@matthewhall435]

Scott I think you need an Milwaukee MX Fuel range of tools for these bigger jobs ! Well done pushing though though !

[@JimmyKip]

I think there's a balancing act with all these sorts of jobs about cost & efficiency and whatnot. But, at the end of the day, if I was your neighbor i'd much rather put up with 1hr of a digger turning up & ripping it out than 2 days of jackhammering :)

[@KoohaEbuyer]

Smoko time is BACK baby!!!

[@andrewcairns5312]

Sweetbix Scott and Ray. More chargers, and more batteries. That will take a long time to change.

[@TaylerMade]

as a retired furniture maker i was always happy to have corded tools, as power source was not an issue. however, i do have battery drills and drivers which are very handy. i feel for builders etc who may have to rely on battery tools, as i am aware of just how expensive replacement batteries are and how often they need to be replaced. personally i think this whole drive to make everything battery by manufacturers, is a bit much.

[@yingle6027]

What you need is a battery powered digger

[@montaake5800]

I remember working at a precast concrete job where I was a dog man for the crane Operater and me and my crane operator saw one window panel was crooked and i had to break all the concrete all around the window so that the remedial guys would be able to put the window back straight again. Yeah it took me nearly 2 weeks 😂😂 now seeing this video , it brings me memories ahaha

[@Jussi_Huhtiniemi]

I have to do my easter egg hunt every time I'm away from the jobsite and someone decides to borrow one of my hilti tools

[@QALibrary]

wow - were these steps built to WW2 bunker specification - looks like they were built to outlast even a nuclear war

[@QBRX]

What a job, a what a cleanup you're going to have to do.

[@Tomevo5880]

Need to use the C8 charger on the big batteries, takes the charger time down from 1hr to roughly 40minutes

[@sessionbox4256]

I could be very wrong here. As I'm a Carpenter and know very little about electricity. My idea is. Maybe the problem with that saw is that combined them batteries make what 44volts using a combined 24ah of power. Since dewalt has the 54volt system would it make sense that the dewalt cordless conc saw would last longer in the same work because technically if it ran on two batteries it would be 108volts. ? Is that the problem here? These big electric battery powered tools need alot of juice but also high power juice at the same time?

[@nzl2004]

Well done on persevering with batteries! Would be great if you could reach out to Milwaukee and ask to borrow their MX series breaker and saw for the next job. If the marketing is to be believed it should be a step up (it certainly is in price)!

[@myeyesarewaiting]

Back in Scotland this would be called "an utter baw ache of a job"

[@Metal-Possum]

I wish powertool manufacturers would stop marketing battery voltage and amp-hours separately. Multiply the two and you've got watt-hours, which is by far the most useful way to measure a battery. A 4Ah battery at 18v is not the same capacity as a 4Ah battery at 12 volts for instance. They love plastering the voltage all over their tools because people buy it thinking it's somehow better or more powerful with a higher voltage. The tool manufacturers aren't saying that's how it is, but they're certainly not making any effort to say how it isn't either. If you've got two identical motors, and two batteries using an equal number of cells (each cell with the same ratings) but one configured with a 12v power supply and the other with an 18v power supply, the higher voltage setup will spin faster but with less torque. Try and compare the amp-hours for both and you'll find that although one pack has a higher voltage, it has less cells in parallel so it's unable to provide as many amps (which can put more stress on the individual cells under load), which in turn means less amp-hours. However, the available energy in both packs will still be the same. In short, more cells in series makes for a higher voltage, more cells in parallel allows for better discharge capabilities (aka the C-rating). If you take a 100 watt-hour battery and power a 100 watt light bulb, the bulb will glow for roughly one hour. If you take two 4ah batteries, one at 18v and the other at 22v and use them to power a separate 100 watt light bulb each, then you'll need to pull out a calculator because the Ah rating has suddenly become meaningless.. Ah is only how much current (amps) a battery can deliver continuously over an hour, where as Wh is how much power a battery can deliver over an hour. High school physics and those little triangle formulas Amps (current) x Volts = Watts (power). And lastly, if you do have one of these higher voltage batteries with relatively few cells in parallel, they're much more prone to voltage sag when they are loaded up. If they can't deliver the desired current (amps) the motor is trying to suck from it, then the voltage will tank while the battery is under a lot of stress. Thanks for coming to my Ted talk.

[@ds61821]

Yep. Batteries for tools that need to do this sort of hard work over time don't make sense. It would great to have heavy-duty tools have the ability to be both battery powered and to plug into an electrical outlet. Are there such tools?

[@RFC3514]

It probably wouldn't be _too_ hard to create an adapter for these that simply supplies a steady 22 volts to the battery terminals, but these brands tend to have "smart" battery systems, meaning you also need to fake the data signals, so it's not necessarily something a normal user can make, they'd need to know how the tool communicates with the battery. And, of course, the adapter would probably weigh more than the batteries.
