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...
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...
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 I refuse to spend 100 USD or more for genuine NiCd battery, because they aren't made anymore (screwdriver is obsolete, but still works).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.
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. ❤
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".]
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.
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.
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.
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 !?
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.
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.
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?
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.
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.
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
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.
@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!
IMPECCABLE AND BEAUTIFUL WORK I'm going to try to do something similar with mine, can I use 6 18650 22F 1A62 batteries recycled from a Laptop? It will be harmful to the drill if I use 6 batteries and a BMS 6S 12 A in Venezuela I only find 12 amps ... will it work?
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?
Another excellent video thanks. It would be helpful if you could go into more detail about charging differences. Can the NIMH charger be modified to charge the 18650 batteries? If so, how?
You really want a Li-Ion specific charger for charging these cells. NiMH and Li-ion (as well as LiFePO4, NiCD, etc) batteries all charge slightly differently. Depending on the battery chemistry, the voltage or the current could vary throughout the charge cycle. Multi-chemistry chargers are made, but they have to detect the type of battery chemistry in the cell before charging. Probably out of the scope of these videos.
Is there a reason u used 100A bms? Because I tried mine with 40A and wouldn't start at fool speed! is working only if I press the trigger slowly! PS the 40A bms is working fine on other drills but no on the Dewalt
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 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.
So few words but probably the best video on this topic I've seen
Watching you rehabilitate these old tools destresses me I really appreciate that thank you .
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.
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 videography is getting better and better, dunno how many comment on that. So good job. :D
Thank you, I'm glad to hear that.
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 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. ❤
I have the same product now. If I use a 5s 25 Ampere BMS, will it work?
Thank you for your solution. From now on no 18v Dewalt Battery is available because it had been discontinued by Dewalt Co.
Very professionally done. Answers all the questions I could think of and then some.
I see the changes in the way you film the videos, keep up the good work 😁👍🏻
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 👍👍👍👍👍👍👍
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".]
Good work Done 👌

Im happy that we changed from nihm to li-ion
Yes, I'm glad you like it.
Muchas gracias por compartir tu conocimiento me gustaría consultar cuanto tarda en cargar la bateria
thats crazy, batteries should wrap up with insulation to prevent short in case the casing is damaged
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.
Well done 👍👍👍. Thanks for sharing
This was great!!
Thank you!
Very useful👍👍
The drill's official battery has a lable says 18V. Does using 21V battery damage the drill?
nice rebuild
Buck converter is used for increasing the voltage and can be used as charge er for battery pack of 12 18 21 24 etc
Gear Show, the best
Thank you Soul Man!
muchisimas gracias por compartir tan valiosa informacion y tan profesional. Feliicidades!!!!
Very nice sir good work keep it up
Using that water pipe was genius!!! Thanks my friend from uk 🇬🇧👌🏼
Excelente idea.
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?
Хорошо протестировал , тиски выдержали .!!
LOL
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 !?
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.
Thank you brother
Great video, thanks. Can I use the original charger or won't work with lithium batteries?
Ok, i'll subscribe because this is amazing
Es necesario usar el convertidor? O con un cargador de salida 18 a 21 volts ?
Gracias por compartir su conocimiento. Me gustan todos los sonidos que se producen durante la reparación.
Un placer, me alegro de que te gusten
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.
Wish I could buy that li ion battery pack from you. I tried one from China that was quickly defective.
I was waiting for your new post
Why you dont remove resistor for 5s?
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.
You should use INR18650 25R 20A batteries because have big maximum constant output load current
Yes, thank so much for the information.
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!
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?

Buen trabajo 👍 y una belleza de soldador de puntos..
Nice vídeo , bro !! Like
Thanks for the visit
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.
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.
Thanks sir
👌👍👍🙏🏻
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..
can i use my laptop charger for the buck converter the charged is 19.5v
Excellent !!!!!
Good job
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
I made same but drill stop once i do pressure on concrete.
Hello ! do you think a 30A bms is enough for a 20v hammer drill?
No
Se puede usar un cargador de laptop de 19.5v
O el voltaje de carga tiene que ser mayor a 21v
Fantastic as usual. Wish you could rebuild some Makita betteries for me.
Maybe one day! thank you for let me know :)
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.

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
Thanks your videos
rebuid 18v battery look good
Szép munka!👌👌👌
Thanks 👍👍
After re. Building the battery pack how much volt is applied to charge for this battery pack
Thanks❤❤❤
Where would i buy this kit and the charger,, thank you great video
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 love to get replacements battery like that for my XRP card less drill it's hard to get battery
Amazon you have
Why not use the DeWalt charger to charge the battery?
It is lithium battery.
Can you tell me how battery AMP use , can i use 2 AMP 18650 ?
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!!
th-cam.com/video/zvs5Uzocnfo/w-d-xo.html
Can this battery pack charge with old charge er of dewalt
how the charging amperage is calculated on these batteries, you showed a 2000 milliamp charger, as you calculated???
Congratulations, you can put the link of the charger😊
@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, 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.
It is ok to combined 18V tools using 20V battery?
Please, spécifications of cells used? Maximum discharge current ?!!
IMPECCABLE AND BEAUTIFUL WORK

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?
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
Is there a reason u used 100A bms? Because I tried mine with 40A and wouldn't start at fool speed! is working only if I press the trigger slowly!
PS the 40A bms is working fine on other drills but no on the Dewalt
Did you manage to solve the problem? I have the same problem, the drill turns and stops. With bms of 100 A does it work?
How this convert or is used for charge lithium ion battery pack reply details of this
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.
