I like the fact that you don't complicate yourself when making these batteries. I've seen a few other battery makers try to combine various types to get the most power possible and it seems like such a risk for what is an unrealistic reward. In other words, too good to be true. I'd rather + the original by a decent margin and have a dependable battery rather than a potential risk. So kudos on that too.
Disagree. I refuse to spend 100 USD or more for genuine NiCd battery, because they aren't made anymore (screwdriver is obsolete, but still works). Besides NiCd degrades by months if not in use.
Same system and same board that I used. I didn't have the proper diameter piece of plastic that you did, so I drilled out the dead NiCad. It charges fine in the DeWalt charger. I have heard people say that theirs didn't. The only difference I can imagine is that I left the 10K termistor attached... Maybe the DeWalt charger checks for that...
Let me give You little hint. Please start using thicker cables when You are connecting B+ and B- to BMS and from BMS to battery connectors. There is a lot of amps there. Your cables looks like 1,5mm² or around this. Look how thick original cables are. Its for Your safety. White ones in this video are good for balancing but not for carry load like 50A...
I love it ur style, i used my drill on car battery 12v 38 amp. It was amazing work, i followed your instruction and renew my old battery and i m so happy its work so nice. ❤
This video is great! It shows you how to build a rechargable battery 18v battery pack. And if you have $priced these battery packs, you will find this video a great help.
Nothing like now having to buy a spot welder in order to save money on a battery or three. (As I always say: "It's impossible to have too much money, too many tools, too many supplies/spare parts, and, especially, too much room to use and store them in".]
U was used a 4s bms , thats why the red light was turned on on the first place , after look like u remove that little diod and things start to be normal . But in my opinion u need a biger wirig on negative side , and a constant amperage too ,about 1 amp in your case.
Are there any updates to this build? Does it still work? I ordered all of the necessary party to rebuild 20 with the exception of the batteries. I’m going to wait until China delivers before I order the batteries. Any recommendations for a battery source?
No, it won't work for long. With multiple batteries, one would discharge more than the others, and they would not recharge equally. Soon, it would stop working.
For the 5. Batter the csble must be much thicker. I am not talking about the balancing wires. The series cable. it must be able to hold at least 15-20a.
Great video, as always. You mention a buck converter. Can you be more specific as you were with the other pcb used. Huge thankyou and pleSe keep it up.
Is it possible to use a 110v charger (Ni CD battery) then use a low voltage circuit like you to charge a DC 12.6V LiOn, Lithium battery? I have a 110V Black Decker charger but the Volt outputs 18V, even though it's charging for a 12V battery. Thank you Gear Show. Hoping for an answer.
I connected exactly like you but my drill goes only like one minute a drain the batteries and if I recharge them in two three minutes like goes green but won’t last what I could do wrong?
unfortunately no, the way you charge NiMH or NiCad batteries is quite different from Lithium ion batteries as Li-ion battery empty voltage starts relatively low and rises significantly as it is charged, and if it drops below a certain threshold or is overcharged it can easily catch fire. The original charger can accomodate for none of this. However, I assume you could gut the original charger and put in the buck convertor or a standalone 21v DC power supply and (assuming you wire the batteries to the terminals properly) it should work fine
Different marketing terms. Nominal voltage versus fully charged voltage. Notice how you see 20V "Max" tools now that are interchangeable with the older 18v tools. Besides that, these tools have a tolerance for voltage--they have to, because batteries naturally fall as the charge state falls. Probably from about 20.5-21v on a fully charged battery to about 17.5 or so on a really dead one.
Uma Parafusadeira Dewalt XRP antiga 14,4v, coloquei uma bateria de 16,8v e ela tá funcionando de boa, estou com vontade de por uma bateria de 20v será ela guenta de boa !?
Will the mA matter for the charger? I have a few 19v 3.95A chargers. Would that be too many mA for the batteries? Best video I found on this. I have maybe 10 of these. Can't see paying $100 for another. Can literally just buy a new drill for that price. Thanks.
hello all right, I mounted the same battery pack with the same bms, but I don't know how to identify the B1, B2 and others. Can you help me, for bosch old bosch 18v.
Awesome video! For those of us who don’t have a nice spot welding machine like yours, do you know another way to connect the batteries together? Is traditional soldering an option? Love the channel-subscribed!
Since no one answered yet. Yes, soldering is an option, if done correctly. You mustn't overheat the cells, therefore you need a soldering iron with at least 80W and big and solid tip, so you only have to touch the cell for a max of 2-3 seconds for the solder to flow. I have seen tests where, if done correctly, it doesn't affect the capacity of the cells at all.
@Gear Show Hi! Did you remove a component from the gms circuit board? I'm following the video but i have two batteries that when measured indicate 0V which is a bit odd. So I replaced them but same result. Maybe the wiring? Anyway hope I get it to work thanks for the video!
hi bro, I can't find the 3200mah batteries do you have a link where to buy them? Or if I replace them with 3500mah batteries, do I have to change something else too?
You make the best videos no talking no music just pure genius thank you so much
I'm so glad that you like it. Thank you!
Mmm.. I love that part - no music, no silly talking, just pure enjoyable job well done.
Totally agree
little_ brat wkkwkl
Me too. Music = dog, talk = eat shjt
Que buen video y sin esa tortura de música de fondo.
Watching you rehabilitate these old tools destresses me I really appreciate that thank you .
So few words but probably the best video on this topic I've seen
You the best repair men i ever see
So you got blind at a young age?
Thank you so much!

That what I want to hear, thank you very much for your hint!
Also the lithium cells used here are no way near rated for the current needed under heavy load. This is not a safe build.
Correct ! I highly recommend you to use copper wires.
Can you, pls, put here the video in which you make the ties between BMS and the lithium batteries to ensure the electric balance between then?
Thanks for the video. No dumb intro and crappy music. Perfect 👍
Thank you! I'm glad you like it.
I love it ur style, i used my drill on car battery 12v 38 amp. It was amazing work, i followed your instruction and renew my old battery and i m so happy its work so nice. ❤
Thank you for your solution. From now on no 18v Dewalt Battery is available because it had been discontinued by Dewalt Co.
I'm not into this gears, but just to say the final work is absolutely awesome. I enjoy and relaxing watching this kind of videos. Very great work.
I have the same product now. If I use a 5s 25 Ampere BMS, will it work?
This video is great! It shows you how to build a rechargable battery 18v battery pack. And if you have $priced these battery packs, you will find this video a great help.
Thank you for showing me how much of a pain in the ass this is. I'll just buy the lithium adapter!
Good job mate & now I'm going to do the same to my Drills, thanks for sharing 👍👍👍👍👍👍👍
Very professionally done. Answers all the questions I could think of and then some.
thats crazy, batteries should wrap up with insulation to prevent short in case the casing is damaged
Nice job. your spot welder is an asset.
Nothing like now having to buy a spot welder in order to save money on a battery or three. (As I always say: "It's impossible to have too much money, too many tools, too many supplies/spare parts, and, especially, too much room to use and store them in".]
I see the changes in the way you film the videos, keep up the good work 😁👍🏻
The videography is getting better and better, dunno how many comment on that. So good job. :D
Thank you, I'm glad to hear that.
Im happy that we changed from nihm to li-ion
Yes, I'm glad you like it.
Good work Done 👌
.
Thumbs up 👍
👏 👏
Thank you so much 👍
@@gear_show welcome ☺️
Bro at 9:10 when you try to remove spot welds on ni-cd, next time use a tiny drill bit in the spot welds it will weak welds and it will help
Use a Dremel grinder to weaken the welds, less chance of drilling thru to battery.
Muchas gracias por compartir tu conocimiento me gustaría consultar cuanto tarda en cargar la bateria
U was used a 4s bms , thats why the red light was turned on on the first place , after look like u remove that little diod and things start to be normal . But in my opinion u need a biger wirig on negative side , and a constant amperage too ,about 1 amp in your case.
Хорошо протестировал , тиски выдержали .!!
LOL
Perfect work, perfect video 👍
The drill's official battery has a lable says 18V. Does using 21V battery damage the drill?
Using that water pipe was genius!!! Thanks my friend from uk 🇬🇧👌🏼
Bro you are a magician i was just thinking about upgrading mine from ni-cad to Li-ion
Oh, because our sense is connected.
That's True
@reedhan paliwal means?
Well done 👍👍👍. Thanks for sharing
Gracias por compartir su conocimiento. Me gustan todos los sonidos que se producen durante la reparación.
Un placer, me alegro de que te gusten
muchisimas gracias por compartir tan valiosa informacion y tan profesional. Feliicidades!!!!
Would I be able to add a battery to one of the cells, meaning using 6 batteries in a 5 cell configuration?
Same question, here..
Are there any updates to this build? Does it still work? I ordered all of the necessary party to rebuild 20 with the exception of the batteries. I’m going to wait until China delivers before I order the batteries. Any recommendations for a battery source?
Buck converter is used for increasing the voltage and can be used as charge er for battery pack of 12 18 21 24 etc
nice rebuild
Thank you for the Idea. I have just one question. What if I didn't use the BMS and just put it back on the charger. That should work also, right.
No, it won't work for long. With multiple batteries, one would discharge more than the others, and they would not recharge equally. Soon, it would stop working.
Hallo , ik wil een aan aantal dingen maken gelijk die schroevendraaier tafel op wielen .
Kan ik er een modek van krijgen met maten of schets
I did same way what you did. But as soon I connect B1 wire to bms. The wire catch fire. Could you please tell me what I am doing wrong.
Hello ! do you think a 30A bms is enough for a 20v hammer drill?
No
Very nice sir good work keep it up
For the 5. Batter the csble must be much thicker. I am not talking about the balancing wires. The series cable. it must be able to hold at least 15-20a.
This was great!!
Thank you!
Great video, as always.
You mention a buck converter. Can you be more specific as you were with the other pcb used.
Huge thankyou and pleSe keep it up.
Buen trabajo 👍 y una belleza de soldador de puntos..
Great video, thanks. Can I use the original charger or won't work with lithium batteries?
Is it possible to use a 110v charger (Ni CD battery) then use a low voltage circuit like you to charge a DC 12.6V LiOn, Lithium battery? I have a 110V Black Decker charger but the Volt outputs 18V, even though it's charging for a 12V battery. Thank you Gear Show. Hoping for an answer.
Es necesario usar el convertidor? O con un cargador de salida 18 a 21 volts ?
Fantastic as usual. Wish you could rebuild some Makita betteries for me.
Maybe one day! thank you for let me know :)
I connected exactly like you but my drill goes only like one minute a drain the batteries and if I recharge them in two three minutes like goes green but won’t last what I could do wrong?
Where would i buy this kit and the charger,, thank you great video
I was waiting for your new post
After re. Building the battery pack how much volt is applied to charge for this battery pack
It was very helpful. I was wondering what it is make and model of the machinr you used to weld. I been made manually
please let me know thank you
how the charging amperage is calculated on these batteries, you showed a 2000 milliamp charger, as you calculated???
Why you dont remove resistor for 5s?
Very useful👍👍
hi, does this board have cut-off protection when voltage goes below certain value?
how do i know which protection plate to use? I have an 18v screwdriver.
it has 5 18650 batteries at the factory.
Excelente idea.
Gear Show, the best
Thank you Soul Man!
Can you try to do the same thing with Milwaukee 18v nicad to lithium battery?
Some reason all related videos only showing about the converter.
rebuid 18v battery look good
I rebuilt a slightly smaller dewalt battery, only fit 3 cells inside but the 30A ones are still plenty for drilling steel with 12mm bit.
Oh, it is really powerful. Thank you for sharing!
Can someone tell me can this be charged in the original yellow charger? Thanks in advance
unfortunately no, the way you charge NiMH or NiCad batteries is quite different from Lithium ion batteries as Li-ion battery empty voltage starts relatively low and rises significantly as it is charged, and if it drops below a certain threshold or is overcharged it can easily catch fire.

However, I assume you could gut the original charger and put in the buck convertor or a standalone 21v DC power supply and (assuming you wire the batteries to the terminals properly) it should work fine
My question is why my bms in b1 and b2 has 3 points to solder, is it correct if I connect it above the three?
Wish I could buy that li ion battery pack from you. I tried one from China that was quickly defective.
Can you send me a link for the wires attached on the line and load side of the buck converter?? I’m not even sure what to call it to look it up....
sir i want to ask that where you find those items
and recomend a place or web side for buying second hand and old tools
i would also like
Those tools are in japan recycle shop.
AliExpress
@Sam S I just tried searching LED and BMS circuit on aliexpress, didn‘t see any dildo stuff.
@Sam Short, LOL! One of my faivorite girlfriends "Glowed in the Dark!".
Buen trabajo, pero no has pensado en usar celdas 26650? tienen el mismo tamaño de las de NiCd y el mismo voltaje de las 18650. Como siempre, te sigo!!
ruclips.net/video/zvs5Uzocnfo/видео.html
You should use INR18650 25R 20A batteries because have big maximum constant output load current
Yes, thank so much for the information.
Hi i have a question is it possible to use the original charger on the new batteries
Ok, i'll subscribe because this is amazing
18V Akku Drill but 21V Battery output ? is this good for the motor ?
Different marketing terms. Nominal voltage versus fully charged voltage. Notice how you see 20V "Max" tools now that are interchangeable with the older 18v tools.

I love to get replacements battery like that for my XRP card less drill it's hard to get battery
Amazon you have
can i use my laptop charger for the buck converter the charged is 19.5v
Uma Parafusadeira Dewalt XRP antiga 14,4v, coloquei uma bateria de 16,8v e ela tá funcionando de boa, estou com vontade de por uma bateria de 20v será ela guenta de boa !?
What will You charge the reworked battery with? The original charger cannot be charged with the BMS used
Why can’t the original charger be used?
Is there a way to wire it so it can?
Szép munka!👌👌👌
Muy buen video. Tengo uno de 18v y me.pregunto si puede llevar un pack de 4s. Ya que no hay mas espacio para una 5ta celda. Gracias de antemano
Will the mA matter for the charger? I have a few 19v 3.95A chargers. Would that be too many mA for the batteries? Best video I found on this. I have maybe 10 of these. Can't see paying $100 for another. Can literally just buy a new drill for that price. Thanks.
Thank you brother
Where did u buy the BMS from and where do you usually buy you other parts for restoration? Can you post links to where you buy the parts?
I think it should be www.aliexpress.com/
It is ok to combined 18V tools using 20V battery?
Can you tell me how battery AMP use , can i use 2 AMP 18650 ?
hello all right, I mounted the same battery pack with the same bms, but I don't know how to identify the B1, B2 and others. Can you help me, for bosch old bosch 18v.
You can search your BMS diagram on Google or store you purchased.
Awesome video! For those of us who don’t have a nice spot welding machine like yours, do you know another way to connect the batteries together? Is traditional soldering an option? Love the channel-subscribed!

Why not use the DeWalt charger to charge the battery?
It is lithium battery.
Thanks sir
👌👍👍🙏🏻
@Gear Show Hi! Did you remove a component from the gms circuit board?
I'm following the video but i have two batteries that when measured indicate 0V which is a bit odd. So I replaced them but same result. Maybe the wiring? Anyway hope I get it to work thanks for the video!
Hi, do you also change the charger with a circuit to charge lithium?
9pp0000
I have a question, do you supply the products mentioned in the video to repair the drill?
hi bro, I can't find the 3200mah batteries do you have a link where to buy them? Or if I replace them with 3500mah batteries, do I have to change something else too?
Mis respetos amigo te la sabes 😊😊😊
