Hey I have the same drill, the bateries are almost dead, now I have a tutorial on how to convert it to Li-ion, thank you :D
Now, I'll call you "The King Of Battery" 👍
Love the new spot welder and of course the conversion
NiCds should be thrown out anyway, but the Bosch chargers I know do flash green while charging, even with brand new batteries.
Everything OK, friend? This conversion was great, as usual, but it seemed rushed and not as careful as your other projects. I hope you and your family are well. Thanks for your videos!
Nicely done. And it fast charges the cells if you're in a hurry.
good job mr gear i like the conversion of tools 100 ac to 18 volts without cable they are great!
1:10 SURPRISE!
Estupenda actualización de batería Bosch 12V de Nicd a iones de litio, respetos desde Venezuela.💯🤜🔥🤛👍💯
Hervorragende wissenschaftliche Erklärung, danke
Nicely done 👍👍👍Thanks for sharing
Very nice tool. Great job 👍👍👍
Nice. I would have skipped the NiCad charger and put the charging ports directly into the batteries. Looked like enough room in the front of the batteries.
The video is most interesting but i suggest the orignal charger can also charge this converted li ion batteries because its 14.4 v charger.
A pleasure watch a true craftsman
Thank you!
I did similar thing to 14.4V system, put 3 in series Li-ions for 12.8V. But I kept most of original charger circuit, just added buck converter with current limiting feature. I wired constant current wire to charging LED and constant voltage to charged LED. My settings were 12.8V and limit 1A.
It's safer that way (voltage to battery is controlled by charger aswell) but with BMS it cuts charging out when cells are fully charged-charger just "thinks" that battery was taken out. This way charger can be used to charge old and new (lithium) batteries.
Excellent quality job 😀
So happy you did this!! Only 12500 people on TH-cam did it before you. 🤣
Impeccable thanks for sharing your knowledge I watch all your videos and I learned a lot, a query that recommends when the starting peak of a motor blocks the bms eg 3S 60Amp, puts a capacitor between + and - to absorb those inrush, of what value would it be the capacitor to be polarized or not? thank you from Uruguay
Very nice job man .you are the king
Hi, I admire your work and videos. I have an exact same drill with the same problem: dead batteries. I want to do the same as you. But I have two questions:
1. What is the power (current) requirement of this drill? I haven't be able to find the specs. Your BMS can deliever 20A, which multiplied by 12V gives 240W. Isn't that a bit low?
2. Having a 2P configuration with 20A batteries, they should be able to deliver 40A output, so why did you limit it with 20A BMS instead of putting 40A version?
Thank you for your answer, maybe I'm wrong, I'd like to learn and understand things before I get to work.
What drills can we use the 20a bms for, it has probably already passed the toughest test
Thank you man i had the same drill with your video i fix it it works just like new
Tested on bulletproof piece of steel! Good idea with the charger. Keep on filming!
Thank you! I'glad you like it.
You should not keep one old cell in there. It would be so much nicer if you replaced it with something that can't leak over time.
I use a piece of UK overflow plastic pipe.
It would be amazing if you could put subtitles during the video explaining what you are doing.
thank you teacher
I have the same model drill battery's and charger same problem battery's are knackered drill still working fine must get them sorted to good a drill to leave unused great posting as per usual :-)
Good to know, I'm glad it helps you!
Ich habe eine Frage, warum haben Sie den Schraubendreher auf der Originalladeplatine verwendet, bevor Sie die roten und schwarzen Drähte daran gelötet haben. Hast du einen versteckten Draht durchtrennt??? Ist das notwendig???
What happen if you use the old Charger but you only use the voltage output and delete the other circuit part? Becauste the BMS cutoff the voltage by itself when it's charged isnt it?
Excellent video/job. Just 1 thing that wasn't clear, and would've loved explained, as for a newbie in electronics like me: the changes done on the charger itself. That I didn't understood at all...
Should I use the old charger (for NiCd batteries) to charge the new pack (Li-ion batteries) ? As far as I understand, there is no issue once the charger output is the same as the total Li-ion pack. So, does it work ? Tks in advance !
I also used 3s20 amps bms for the same drill, but the drill does not work when I press the trigger all of a sudden, the pressure works slowly, when I try the batteries with 3s40a bms, there is no problem, but there is a problem with 20a bms, where is the problem?
Круто!!! Спасибо за видео!!!
Gratidão GearShow!
Do I have to change the charger after upgrading the battery..?
congratulations for the work. could you put the links for buying the batteries, control board and charger?
Thank you
Ve CHAPLIN WAS BRILLIANT WITH HIS SILENT MOVIES.
Only an |D|07 makes a video of this nature without a descriptive.
I hate to say it, but you qualify as one !
Where can I get the Li-on charger an the other accesories? Could yoi send me the link, please?
I like it very much 👏
I wonder if its economically viable to do this. I have 2 old NiCD drills!
Nice job
Thank you! Cheers!
Wow . LG Choco. Can also be used for vaping. 😁
Why you deleted the part of the connection from battery to PCB?!
CAN I USE 5S BATTERY PACK ?? CAN THE 12V DRILL HANDLE 20V ?? FOR ME 5S BMS WITH CHARGER IS EASIER
Master
if old Ni-Cd charger circuit PCB have TL431 code component(Like BC series transistors) you can adjust output voltage for Li,-Ion batterys .I think you can adjust on old adapter with trimpot LED indicator too (LED on is charging ,LED off is charge done )
(Only you will change 2 resistance value.You an find details in youtube videos for TL431 output voltage adjust).So not need any new Li-Ion charger.
If have not TL431 component in old Nİ-Cd adapter ,you can remove last section components (after bridge and big capacitor circuit ) and you can connect XL6009 DC-DC converter to removed area and you can adjust output voltage on chip module
Для 12 вольтового вполне хватает 3 высокотоковых аккумуляторов и плата вмs 3с40а и работает как часики
Spettacolare sembri una fabbrica come nuovo
How about corded rotary tool to cordless?
請問您是住在日本嗎？
怎麼拿得到這麼多日本製的舊電子產品，
我之前看您的影片Bosch PDR ，
修好我從回收廠撿回來的Bosch GDR 14.4
調速開關一樣是壞的，只能最高速～但這樣鎖螺絲容易滑牙弄壞螺絲頭
我發現其實大多速的調速開關是通用的，
只是大小形狀不同，要修改～
淘寶有類似Bosch的開關可以買來改
來自台灣的粉絲留～

nice work
Thank you!
hi i saw you use the batteries/electrical drill ( the white color one ) could i ask for the brand and name thank you so much. please continue to do these repair im a beginner and like to learn more, wish if there's an discord or a place to chat in the future thank you . you are awesome
hi,, I have a bosh gsb 18v VE-2 old ni-cd 3000mah, possible convert it ? what battery charger protection system pcb I need use ?
how much cell I need ? thanks
I did same upgrade with batteries, but charger left it in its original condition . No functional problems (maybe slower charging)
You should throw away the NiCd battery, it will leak and oxidize with time and ruin the entire battery pack. A piece of PVC pipe would work very well.
Thank you very much friend about this video
Please can you show me where i can buy like this cell li-ion 3.7
And how can i know it original or fak
Just when I needed something to watch 😎
Hello. Thanks for the video, it's interesting.
But in my opinion this particular BMS is a bad solution.
The DW01 control chip will turn on the current blocking when it reaches 75A, because 0.150V/0.002R=75A. Are you sure that this screwdriver needs 75A*~10V=750W power?
The DW01 control chip turns on blocking when discharging to 2.4V - this is a lethal voltage for 18650.
The DW01 control chip believes that batteries can be charged up to 4.28V - this is also bad.
the table knock sound is very loud ,pleas low it later
i hope to make a video of turn the angel grinder from 220 v to common dc voltage battery by rewinding method... thanks
Very nice!!!!!!!!!!
Thank you! Cheers!
Sir, I want one clarification. In the video, the previous drill charger charges ni-cd batterie pack. But after changing to lithium ion batteries, as you showed in the video. Can the previous drill charger charge the replaced batteries.
Si lo può fare l'importante è non dare un alimentazione di troppi A il voltaggio può variare di poco o essere superiore o essere lo stesso 12v mai superare i 3A altrimenti potrebbe scoppiare una batteria
Комментарий в поддержку видео и канала, а также труда мастера который отреставрировал.
Dove posso trovare i vari componenti puoi mettere i link?
Grazie e complimenti
nice
Fume extractor with tripod..good idea!!!
Where did you buy this sir...?? Can you shipping to my county Indonesia..
you used a BMS so the original nicad charger will make the job with no or very little modification ;^)
Stesso trapano con batterie andate vale la pena recuperarlo?
Nice

What are the voltage of each battery ,what modifications done in old charger. Pl explain to easy language
I am not an expert but there are 6 batteries, each having 4.2V when charged. The batteries are wired in pairs. Each pair is in parallel, and the pairs are in series. This makes the total charged voltage 4.2V x 3 = 12.6V. For the old charger he destroyed the traces on the charging circuit so that it was no longer connected, then he soldered wires to the contacts for the battery pack. These wires lead to the barrel connector jack where he connects the new charger, which is an AC to DC power brick that outputs 12.6V to charge the new battery.
@@Jnes01 Thank you so much for giving good information
Bên đó ko nhập mạch 3S30A nhỉ, thấy ông này toàn đóng mạch 20A, mạch này tải nặng cái là ngắt liền, hơi kém.
Почему плата защиты не уходила в защиту? Какие то циганские фокусы!
Vc mora onde ?
Li ion battery👍👍
Hello . You didn't show from which end of the battery the wires come from while the battery is in a flat position? that you cut the soldering scene to the batteries in 22 seconds of 4 minutes of the video.. I'm so angry
Can I send you my power drill? I would love to se le the drill alive again!
Mạch này nhận sạc zin luôn hả bạn
Porque não liga direto o plug de carregamento na própria bateria
Tem que ter um gerenciamento da corrente de carga, e é isso que aquela plaquinha verde faz.
I have seems like that 😁
👍👍
❤️

Lo entiendo todo menos la modificación que haces de la PCB. No sé si puedes explicar.
El PCB tiene 4 conexiones B0 (0V), B1 (4.2V), B2 (8.4V) y B3 (12.6V). Soldé todas las conexiones al paquete de baterías.
@@gear_show ok. Que es lo que haces en la PCB del cargador original?...cortas algunas pistas?
👍👍👍😎
Разъем для зарядки можно разместить на самой батарее. Тогда зарядка Bosch вообще не нужна. Я так сделал.
6:17 Шайтанама!
👍👍👍👍👍👍
Super :-)
Thank you! Cheers!
👍😉
احسنت. واصل
شكرا لك!
👍
what size are those small Ni-Cad cells? and are there any direct swaps with Li-Ion? seems like less effort than shoving 18650s in there

En el polo negativo no necesita pegatina
Zdravím mužů nabíjet lipol 3s 5200mah nabíječku 2A 12.6v děkuji za info
Hey bro hru.. nice videos.. what do you call that green board?
Hello, that green board call BMS (Battery Management System). It is used to control all battery cell.
@@gear_show thank you so much bro.. have a good day..
Не верю! Bms на 20 ампер не потянут даже с места сдвинуть патрон, там как минимум 40А нужна плата. И провода слишком тонкие
Máy này sài pin mà mạnh dữ
Did he leave 1 no cad battery
Ni cad
