- Modifying a DeWalt 18V battery to work with DC power supply, works with any 18V power tool so to have a dual system (cable or battery) so no need to wait for a recharge or buying expensive replacements.
Stop buying expensive batteries. This serves as a backup system in case all batteries fail and the job cannot wait them to charge.
Everything you do is under your own risk, only you are responsible for your actions.
The DC power supply is an 18V that pulls up to 19V and 19Amps. This one works right now with a DeWalt battery but I plan to also modify a Black and Decker battery. - Jak na to + styl
Seriously man, one of the best how to videos I've seen in a while. The edit was perfect. Tons and tons of info.
Thanks for your time man.. well done
Hey! You stole my idea 🧐 Haha, only joking... but i did have this idea and i am approaching this issue from a different angle, but the outcome is the same! I dont belive i should have to pay the price for almost a new drill in order to replace the battery. So, like you, this was my initial idea also, which is to return back to cable drills and ignore the issue that most people prefer cordless ones!
You are a clever man like myself lol, but we are two of many people who think outside of the box too!
Well done!
Well enough and with a lot of prior research, ive been able to do a similar setup for my obsolete ryobi combi drill 14.4v just now.
Although i use a 12v (adjustable to 14.5v) with 30a output for the sake of being able to pull more amps and torque. I used a 20a in-line fuse and nothing has gone wrong so far
A lightweight psu is now mounted on a very heavy woodbox. Nice...
Nice video but looks like you went way above and beyond I did similar but used a laptop power adapter though I'm not getting enough power for my craftsman 16.8v drill some old reason this is an old battery and it still cost way more than newer versions I will try a higher output power supply in future.
I just hut the batteries out and left that one battery on top cause it was connected to those top 2 terminals and ran wires inside soddered then to positive and negative and just snap in place and it's done still not alot of power this is like someone mentioned you need right voltage on load or your not going to get right power.
But have to admit you did a good job 👍👍
I rewound an mot to the V i wanted then fitted a bridge rectifyer in the emptied battery case and a smoothing cap. . I fitted it in a small tub with a lid and connected with bannana connectors. loads of torque
Love this video. Where did you get your power connectors?
Many thanks and to answer the Q of what’s the point I have many desalt tools I use in my shed and on site and some really put load on batteries and some times beat the chargers so you then have to wait. Thanks again
But if the screwdriver needs 3.5 A to work properly, if you leave a switching source of 19a does not run the risk of the screwdriver pull more amperage and burn with the time?
i'm still waiting for the Black and Decker version. I have 2 X A12 batteries and an empty A12 casing just waiting for you to show us how to run it of an alternative power supply
big power supply 30A -50A, 15-30V adjusted voltage, LCD display for circular saw, reciprocating saw and hammered drill and big hole saw
After seeing this video, I’m thinking about finding an old 12 volt cordless drill and converting it’s battery pack into a cigarette lighter adapter, so it could be run off of a car.
my model is a black decker GC1200 12v. what source can I use which amp
Muy bueno el video, voy a intentarlo en el mío q murió la batería. Perdón q te hable en castellano pero es q a los 3:21 el mate te delata jaja gracias x compartir la info!
Jaja tambien lo ví
Pero talvez no habla español solo toma mate
love this!! I have been trying to figure a way to keep the converter inside the old battery case and have a 110v cord come out. I dont think my idea is possible. Please tell me more about your power supply Watts? What do you think is the lowest needed amp draw for a power supply. Where did you get yours. Thanks for the video.
+Swartz Robert I bought this one on AliExpress under the name "S-350-18 350W 18V 20A Single Output Switching power supply for LED Strip light AC-DC" and it's a 350 Watt (18 V x 20 Amps).
Without load I get about 4 Amps for my drill and about the same for my circular saw, with load I expect tools will consume about 10 Amps and with 20 Amps I am more than covered.
I am planning on doing a Part 2 of this video where I added some 15 Amps fuses, not to protect the tool but to get a warning if I exceed 15 Amps. Also in Part 2 I am planning to add how much power tools consume with load but it takes a lot of time to film and edit videos.
This works very good for me and so far I had no issues at all. I extremely recommend using something like this. I did not liked the idea of having 110v so close to my hand so I ended up using this power supply next to the power outlet. I also thought to have everything built-in into the battery but this power supply is pretty big and then I also realized I have more 18v batteries from other brands ;)
Thank you for the comments, have a good one!
I don't think you could find a switching power supply fits you drill battery with enough power. the switching power supplies contains big capacitor and inductors those are the heroes responsible for giving that much amps to crank the drill
Yeah, I agree with you, I tried fitting the power supply inside the case but I cannot get a small unit powerful enough.
Swartz Robert 19 amps, 350 to 380 watts
Anyone know of a configuration more like a laptop?
Where... you keep the battery and runs mains at the same time... but when you pull the cable, it diverts to battery automatically? and when you plug the cable back in, charges the battery also?
Hi. Thanks for this video. I have a Bluetooth speaker which is the Sony SRS XB 30 (it's a rechargeable battery powered device) and I want to convert it into AC power supply. Can you please tell me what's the volts and amperes that the adapter needs to supplies the sound device very well?
Great idea ! Thanks for sharing.
Just one question. What kind of plug do you use between the DC power supply and the drill ?
+Albert Legroin I used these DC low voltage plugs (LED or CCTV) I actually bought several different DC plugs and these seem to work ok. I cannot get a heat shrink around it comfortably so this is something I may change in the future. I was unsure on the current these plugs are rated for but so far so good.

+dvbdvbdvb
Ok Thank you dvbdvbvb.
Why not use a regular plug if you take care to identify poles ? You can use larger wires and heat would not be a problem i think.
+Albert Legroin I think is more a safety thing. I don't like the possibility of someone plugging in a DC hand tool to 110 or 220v AC. This is why I chose to use a different plug so nobody will ever confuse plugs.
+dvbdvbdvb I understand, It is a good reason !
May be you can use a 12V cigarette lighter socket.Thank you.
+dvbdvbdvb - I had wondered the same thing but realized that someone not knowing better could walk over and plug it into a "regular socket" and that just would not end well.
wow. a hybrid.... can do both corded or cordeless
I have a screwdriver and circular saw that work on the battery. The original battery has 12v/2.6A.......... Can I use a LED tape source that has 12v/5A? or a 12v/10A switching power supply? Or you don't recommend?
my circular saw peaks at 15/20amps, I would not that power supply.
The idea is to eventually recharge the batteries directly from solar panels, so there is need to connect to the AC grid ever to be able to use your tools. Plus the electricity will then be free.
I am doing this because I found it pretty cheap to buy just the drill or any tool without the battery. and with a cheap switching power supply. you R good to go. I think tool manufacturing companies today are doing this on purpose for their own benefit. like what Kodak did back on days with film cameras. it sell the camera with more than 5$ loss and get the benefit on overpriced films
printer companies are doing the same thing almost give the printer away and charge a great amount for the ink cartridges....
@@jimmytate7587
Get the EPSON model that has actual ink TANKS on it. No cartridges. It is one of my best purchases ever on Amazon. Been using it for years and the bottles of ink for refill are cheap. I would not sell my printer. It also copies and scans, in one small package.
What about reverse polarity?
What kind of power supply is that?
Where did you get that DC jack that connects to the battery compartment to plug the cord into? Also, what cord is that?
Steve D I bought several online but then I realized that is the only thing that gets warm, so my guess is that they are not rated for that current, I tried some other plugs but more than likely I will replace these in the future, get some adaptors online and try them out, the only consideration I take is that the plugs are not like the ones we use for 110v or 220v so that nobody plugs accidentally the drill to 110AC. They work great but I am not 100% happy with them, go on ebay and type DC male female connectors. The cable is a normal 2 wire 10 or 12 gauge cable.
Ok, thanks for the reply, I may just run it straight into the battery with some strain relief. I'm gonna put the power supply in an ammo can mounted to the side of the inside with some holes cut for air flow, and install an IEC power jack to run to the ps in the ammo can, (so I don't have to worry about hitting that mains power). I'm pumped about this, and sick of these batteries crapping out. At least now I'll be able to use my dewalt stuff in the garage
Great
What about a 28V DeWalt power supply?
Can you make a video doing the same thing to a milwaukee m18 set please?
Sure, the guy will go out and buy the exact same drill system as yours, then destroy its battery(!), just so you don't have to use your brain to adapt what you've learned here today to your own damn situation! Maybe you shouldn't be playing with your daddy's tool at all, son!
Would of been nice to see how you connected your wires to the inside of the battery connectors.
Hi , can you make one for a Milwaukee M18?
this is all well and good but kinda defeats the object of buying a cordless drill in the 1st place lol
well... not really because I have both systems now. I can use it with battery or plugged in all in one unit :)
+oldskoolhead0 - Plus it keeps you out of a bind if your in need and have no functioning nor charged batteries at the moment.
Close to locked rotor
What about his computer power supplies you pictured in the video? I have several lying around it would be great if I could just use one of those. Do you think the amperage is enough for our tools? Have you found info on various tools amperage? Thanks for the great video!
Darryl Ferrucci.
it worked for older 18v dewalt drill, but not working for newer 20v drill. Any thoughts?!
I think the 20V are the lithium cells, the drill may have some logic inside to protect the battery pack, check online since you probably have several terminals, either for balance charging or to get an input (for example the battery temperature). I am not familiar with the terminals but you may want to check online to see how each terminal is being used, that may give you some more information on how to proceed.
@@dvbdvbdvb thanks for your inputs! I read about the deWalt 20v lithium battery 🔋 terminals and functioning- looks a bit complicated.
I was able to run a Makita lithium tool off of external power supply. it has 3 terminals. by shorting the 3rd one with +18v it ran!!
Anyone who has a solution for deWalt , please share . 🙂
Excellent instuctions...............
I've been mulling over similar options for ages having expensive batteries dying on me for the last year or so. I have a big wooden garden project (workshop/man-cave) coming up next spring and I love my little range of Dewalt cordless (Driver/drills 12v and 18v and a jig-saw and a circular saw, 18v)
I have a question, if I buy a 24v verision of the LED switching power supply would that be OK to power the 18v tools? As long as the amps and wattage output sufficient of course.....
Thanks for any answers
+Super Grump I would stay with the 12v and 18v power supplies, I do not know what would happen if you plug 24v into a 18v tool but for an optimized tool life I would stick to the original voltage from each tool.
It works great and I definitely recommend doing something like this, not only because on saving money on batteries but also because if you use this when a power outlet is nearby you increase your battery life (from the ones left) by not consuming battery cycles unnecessarily.
I added some fuses that I don't really know if they are really necessary but it was only $2 for a pack of 5.
Thanks for stopping by !
good idea but whats the point of having a cordless drill?
Chester B It's about having options. I like the cordless drill for when you don't have a power outlet nearby and I like the corded one so I don't need to rely on batteries and charging times. For the price of one drill now you can have both!
Yes, but for the price of your project you could just buy a corded drill and have two complete drills.
Pro1er you can find some used corded drills fairly cheap. I spent about $15 for the power supply and let's some other $10 for misc items.
I am using this for both DeWalt and Black and Decker 18v tools and I still have several working batteries. In my case everything ended up being cheaper but in the future I will try to stay away from battery operated tools, like printers, they seem like a good idea and end up being very expensive to operate.
They are a good option when you have no power supply and convenient for remote locations but battery replacement will always be very expensive.
In any case, every person has different objectives and for sure you can buy drilled tools for very cheap, as they break I will replace all my battery operated for corded tools. Thanks!
While I would never give up my cordless tools, I totally agree with the logic. In fact I tell people all of the time *not* to buy cordless tools if they only plan to use them on the rare occasion.
I gave up on inkjet printers decades ago because of the cost and the problems associated with the technology. Not only are they a money pit, but just like power tool batteries, the manufacturers keep changing the cartridges.
Batteries always run out before the job is done. I like to do heavy prep work with AC and then use the battery when installing.
can i use 18v battery in 14.4v brushless drill????
probably not for very long... I have not tried that, depending on the drill and how 'smart' it is it may not even work (if it has voltage monitoring), older ones actually worked just fine, lifespan may be reduced though
hi there, I have a 12v 3.7a xbox adapter, do you have an idea if that would work? Thanks!
Ronald Ong too low amperage, you need at least 10amps...
dvbdvbdvb thank you for responding, would the saw even run?
But if the screwdriver needs 3.5 A to work properly, if you leave a switching source of 19a does not run the risk of the screwdriver pull more amperage and burn with the time?
@@dvbdvbdvb I have a screwdriver and circular saw that work on the battery. The original battery has 12v/2.6A.......... Can I use a LED tape source that has 12v/5A? or a 12v/10A switching power supply? Or you don't recommend?
Can do that on the new stile batteries?
the new batteries are lithium-ion, generally they are the 18650 ones, and since they have multiple cells they do balance charging and by doing so they use multiple pins, not just the + and - terminals I used, my guess is that the tool will check all terminals so you may be able only of you know the checks the tool does before it starts. I know some also have a temperature terminal thar checks the battery pack temp, if it's high it will not start the tool. Also lithium batteries are more dangerous to diassemble than the NiCd ones, so you will need to be carefull, even with a battery pack 'uncharged'
combidate el mate loco
.... How long your power supply will last before it burn without ventillation? ......
it can run with no restrictions since it has a built-in fan... you can see the air vents on the video... still working great!
dvbdvbdvb ...... In that case you has to keep the wooden box open ...... 🖒🖒🖒 ......
Jose Nazamed it is always closed, but I never use it for more than 30 minutes
Where i can buy this power supply ?
Je hej I bought it from China, but you could be playing with fire, you can check ebay or Amazon for a 18/20V - 20Amp power supply and you will get the same I have here. By the way it still works great, I am using XT60 connectors now.
i couldnt get a single thing with all that cutting
Are there any smaller versions of a power supply that would work? I have been hunting for ways to do this without having to build such a large box. How can they make a battery that applies more appropriate power than something like a laptop supply. I read that some power supplies have Inrush current limiters. Is there a way to disable it enough to function and not cause damage?
Zachary Velasco they probably have that to save the equipment, if you disable that you will likely fry the power supply. About the size that depends on what you will be powering, for a drill 10 amps could be ok, but for a circular saw it is not and you may stall the blade if you have not enough power. You can always try but that depends on what you will plug at the end of it.
do you have a link for the power supply?
No, I just mean whatever battery charger came with the battery and tool. Perhaps wire straight from that charger to the tool, is all I'm saying.
I have 2 opinions about this. Me being a tinkerer, maker, hobbyist, whatever you want to call it, I see this as a fun "just because" project. This is the type of things I've always played around with just to experiment and basically have fun with. But it's not really practical. Don't get me wrong, I'm not knocking it in any way, it's actually pretty awesome and may end up doing it myself because I have an old B & D drill with non recoverable nimh cells in it. It's just that there is so much effort put into it and if you have all the resources to do this as neatly and for lack of a better word "high quality?" as you did it, then you can probably just get a new li-ion drill. I feel as though you just did it as a fun project/experiment which is exactly something I would do, just for the hell of it lol. Sorry for the long comment lol. Great project though. I subscribed 👍🏼
You are absolutely right, I already have new li-ion tools so these old one were just collecting dust. I still use it although it has been a few years and it works like a charm, I had to change the connectors once to better ones. Besides that almost 5 years and still running so I know I saved on batteries but the bottom line, it was a fun project.
Some people have an appreciation of resourses and dont want to toss good tools. Most. of course have no thought for the waste they make.
Is it possible to have too powerful of a power supply?
Never.
Yes if you put too many volts or amps through anything.
it can be very bad.
Hi dear! Congratulations! Can you help me whit my screwdriver dewalt 12v DCD710?
Those are the new ones with the lithium cells, I don't know if the drill has some of built in check on the batteries, this same system but using a 12V power supply may or may not work on the newer drills. I know the batteries have more than two connectors to balance the charge between cells, you can pull it off but I would do some research first.
@@dvbdvbdvb That, exactly!
I've done research but unfortunately I can't get good results.
There are three electronic boards that connect before reaching the 12V motor of the screwdriver.
For example, the lithium battery has 4 connectors, that is, it is not simply connecting the positive and negative of a 12V source, because this does not make the machine work.
What do you recommend? Can you help me?
When I connect to my circular saw after turning on power supply trips not work, no supply.
What is the amperage output of your power supply? saws need quite a bit
@@dvbdvbdvb 10 Amps; otherwise suggest which power supply I should try? Thanks
@@darkmatter5310 yeah, that is the issue try getting 20 amps minimum. I got mine over ebay. Don't buy the suspiciously cheap one but I think they are all generic from the same factory, mine was unbranded and still works. Be sure you hard wire a ground connection and that you test it, I have seen before those power supply's metal cases at full voltage
@@dvbdvbdvb Thank a lot, appreciate quick reply.
@@dvbdvbdvb Hello again, I got 20 amp and after connecting circular saw keep making jerking circular motion, start and stop, it looks like still current is not enough? Appreciate
I purchased this power supply and am having issues. If I pull the trigger all the way at first it kills the power supply .If I slowly pull the trigger no issues till I kill the drill with my hand. Then I have to let off on the trigger and slowly pull it again.
Is this supply faulty? IT is 18 volts and 20 amps. www.amazon.com/gp/product/B079NJ63SQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
360 watts
Why do u need a big box for it
you may be ok with a smaller one, I wanted space for cable management, fuses, potentially a rectifier and air flow.
Hello Does anyone know the draw under heavy load?
depends on the tool, a drill could be 7amps with some higher spikes, my circular saw draws about 20amps just before stalling the motor under heavy load, I installed a 15amp fuse for non-circular saw uses and it has not blown yet.
and it still works by the way! I only added the 15amp fuse.
The reason I'm asking is because I want to rebuild a couple packs using 2.7ah li ion cells rated for 3c to see if it can be done. Thank you for the info.
@dvbdvbdvb Does this mean yout circular saw is powered by this same setup?
How long the cable can be?
not sure, you probably want to check voltage drop per ft an max amps on your cable with the manufacturer.
@@dvbdvbdvb thanks
I can't find this or and equivalent ps anywhere on amazon. It is mostly 12v or 24v.
+Paul C it is there, many seller but just one you can check with the title under "
LED Switching Power Supply AC 100V-220V To DC LED Access Switching Power Supply 18V 20A 360Watt High Power Transformer Adapter" or you can buy them on eBay or Aliexpress
Thanks, I just ordered it. $43 & free s&h www.amazon.com/gp/product/B01JGGOQ1C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 - I'm excited to use it with the yellow plastic adapters I bough several years ago. I can also use my cordless circular saw / trim saw again.
That's the only one I could find. How did it worked!
It was either lost in the mail or they never mailed it. $50 down the drain. Left a 1 star review explaining that it never showed up. I asked the vendor for confirmation of delivery but all he said it went to the post office. I gave up and threw out my Ryobi battery to cord adapters because lithium batteries seem to work so well and last longer during use and on the shelf. Thanks for the info.
Too bad. Check out my post, at the top, about the boost converters. That could also be a good option.
could you do this a bit faster next time?
La Yerba que marca es? 😂
siempre Piporé
I have research the universe include manufacture. They can not reveal what is their power tool max load capacity. Only your video show at no load condition.
I am building a microwave transformer and bridge rectifier type of AC to DC converter.
I would need wattage information to calculate how many microwave transformer will needed + rectifier capacity needed to properly convert 120vac to 18vdc.
No where in the world someone can tell me when battery circular saw will shut off at what amp when overload.
What is your estimate max amp for a Bosch 18vdc or 24vdc max amp it can handle?
Elec. Lawn Mow at 120vac has 13amp pull. A small Bosch 18vdc or 24vdc circulate saw can pull how much amp?
+Ka Ye I have seen up to 10 amps 18V DVC in NiCd batteries as a peak. Normal load around 7 Amps depending on what you are cutting.
2 year old comment probably did what im about to say. But check the motor it usually has label. Search the name and it will get you datasheet with your info. Also the switch uses power so add that to the list. The switch also has info on it.
amigo estas tomando mate jeje
Main part needed is 15 dollars... Plus the switch, and the connectors... and time adapting the battery pack to act as a dummy...
Compare that to a 110VAC electric drill from a yard sale that you can get for about 5 bucks. The yard sale drill works with any extension cord and is light and easily transportable to the work area. I don't care how many cordless drills you use, if you don't have an AC drill in your shop as a backup, well... you're just not serious about getting the job done!
This project is well made, safe, but ultimately unnecessary.
I currently have 9 tools, from 3 different brands using this system. I agree if you can pick up a used corded drill for 5 bucks, by all means, but that is just 1 drill, I have a saw, bandsaw, weed wacker, drills, blower and somerthing else under the same device... still working great so I think the investment paid a long time ago. Thanks for stopping by!
@@dvbdvbdvb It's all good...
Dragging that tethered wooden box behind you as you run around the yard with the weed-wacker must be quite a sight to see! ;-]
Exactly. This guy thinks we are starting from scratch and dont already have a bunch of cordless tools. And assumes that you really can just go buy a used tool like that. And he misses that a slow driver drill or impact is not even sold with a cord.
Do some actual work with the drill. I've DONE this. The power supply will freely spin the drill like you have shown, but the drill will not do any actual work. Not enough amperage. Hook it to a lawnmower battery instead. Less volts, but major amps. The drill doesn't spin as fast, but does tons of work, and the battery does not need to be recharged very often.
selador11 it works great, I used this in my other videos, I have a battery operated pole saw and it cuts like butter non stop...
selador11 also this is a 20amp power supply, there is no way you will need more than that in a normal tool (drill, saw, polesaw, edge trimmer). Yours may have not worked but mine works very good, the one thing to keep in mind is that a battery operated drill is not meant to run for hours, so you cannot use it for very long as you may damage it.
I'll give you that. :) It's entirely possible that the computer power supply I used, was of lower amperage. The lawnmower battery still works great, though! And I don't have to use an extension cord. :)
dvbdvbdvb How much amperage does it draw under load? I know it draws around 3.5 under no load.
trickle up if you see my other videos I use it in a circular saw, in a drill to mix concrete and normal stuff. The drill with load consumes about 5 to 8amps, the saw up to 10amps, I recently upgraded the connectors to XT60, I think these are great and what I will be using in the future, now I am working on a 20V battery pack with 18650 cells since in some applications I don't have power and my other batteries as dieing on me...
Toooooooo complicate. Better buy one.
instead of wasting this much time, I connected 18 V adapter with a DC jack in tha old battery pack.
I did it quickly and efficiently with instructions from Avasva website.
Where to buy this power supply?
The guy I bought from is no longer active, you can search online for these, probably all from the same factory, just be safe as these are generally not very secure. Even if you get the ground connection, check the unit is properly grounded, if you see any voltage in the case with the unit grounded I would stop using it.
