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
Love the new spot welder and of course the conversion
Now, I'll call you "The King Of Battery" 👍
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!
Very nice tool. Great job 👍👍👍
Nicely done 👍👍👍Thanks for sharing
Excellent quality job 😀
Estupenda actualización de batería Bosch 12V de Nicd a iones de litio, respetos desde Venezuela.💯🤜🔥🤛👍💯
A pleasure watch a true craftsman
Thank you!
Hervorragende wissenschaftliche Erklärung, danke
NiCds should be thrown out anyway, but the Bosch chargers I know do flash green while charging, even with brand new batteries.
Tested on bulletproof piece of steel! Good idea with the charger. Keep on filming!
Thank you! I'glad you like it.
1:10 SURPRISE!
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.
Very nice job man .you are the king
Thank you man i had the same drill with your video i fix it it works just like new
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!
So happy you did this!! Only 12500 people on CZcams did it before you. 🤣
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!
Круто!!! Спасибо за видео!!!
thank you teacher
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.
Gratidão GearShow!
Nice job
Thank you! Cheers!
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
I like it very much 👏
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.
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...
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.
nice work
Thank you!
Wow . LG Choco. Can also be used for vaping. 😁
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.
Very nice!!!!!!!!!!
Thank you! Cheers!
Spettacolare sembri una fabbrica come nuovo
What drills can we use the 20a bms for, it has probably already passed the toughest test
It would be amazing if you could put subtitles during the video explaining what you are doing.

Only an |D|07 makes a video of this nature without a descriptive.
I hate to say it, but you qualify as one !
Для 12 вольтового вполне хватает 3 высокотоковых аккумуляторов и плата вмs 3с40а и работает как часики
congratulations for the work. could you put the links for buying the batteries, control board and charger?
Thank you
Fume extractor with tripod..good idea!!!
nice
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
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.
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?
Nice

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???
I did same upgrade with batteries, but charger left it in its original condition . No functional problems (maybe slower charging)
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?

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
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 !
Do I have to change the charger after upgrading the battery..?
Where can I get the Li-on charger an the other accesories? Could yoi send me the link, please?
👍👍
How about corded rotary tool to cordless?
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
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.
I wonder if its economically viable to do this. I have 2 old NiCD drills!
Li ion battery👍👍
Why you deleted the part of the connection from battery to PCB?!

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～
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
👍
paper insulators on negative side of battery is redundant !!! think about it...
👍😉
Почему плата защиты не уходила в защиту? Какие то циганские фокусы!
CAN I USE 5S BATTERY PACK ?? CAN THE 12V DRILL HANDLE 20V ?? FOR ME 5S BMS WITH CHARGER IS EASIER
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
I have seems like that 😁
6:17 Шайтанама!
Super :-)
Thank you! Cheers!
you used a BMS so the original nicad charger will make the job with no or very little modification ;^)
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
احسنت. واصل
شكرا لك!
Máy này sài pin mà mạnh dữ
Where did you buy this sir...?? Can you shipping to my county Indonesia..
❤️❤️❤️❤️❤️❤️
❤️❤️❤️❤️❤️❤️
En el polo negativo no necesita pegatina
Разъем для зарядки можно разместить на самой батарее. Тогда зарядка Bosch вообще не нужна. Я так сделал.
Can I send you my power drill? I would love to se le the drill alive again!
Bên đó ko nhập mạch 3S30A nhỉ, thấy ông này toàn đóng mạch 20A, mạch này tải nặng cái là ngắt liền, hơi kém.
Dove posso trovare i vari componenti puoi mettere i link?
Grazie e complimenti

Stesso trapano con batterie andate vale la pena recuperarlo?
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
Vc mora onde ?
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..
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.
Очень маломощная bms для сборки 3х2. С bms на 30 ампер будет мощнее, тем более что hg2 могут 30 ампер, тем более когда х2.
Для такого не сильно мощного шуруповерта пойдёт. Вот зарядное устройство обязательно ли переделывать? Заряжаю переделанный на литий АКБ штатным для никеля. По окончании напряжение на клеммах АКБ 12 с небольшим вольт
@@lenovtab3246 У меня сборка из трех hg2 и bms на 30 ампер для такого же шуруповерта, тянет саморез 5х100. Собирал изначально почти на такой плате bms и шур уходил в защиту почти на любом саморезе длиннее 30-35 мм. А вот с зарядкой стоит быть аккуратнее. То что твои аккумы терпят заряд от родной зарядки, значит лишь то, что они довольно устойчивы к высокому току заряда. В первую очередь это для них не очень на пользу, во вторых несколько опасно для тебя. Bms ограничивает лишь нижний и верхний предел напряжения на сборке, плюс балансирует банки. Но для сборки самое опасное, это черезмерно высокий зарядный ток. Так что лучше переделай зарядник. На Али есть dc-dc преобразовател недорогие с стабилизацией по напряжению и току, его можно встроить в родной зарядник.
@@user-ns2zr7lo8m 2.6 Ампера выдает штатное зарядное устройство. Для аккумуляторов 2 Ачаса - не сильно больше номинала. При заряде аккумулятор вообще не нагревается ни на градус. И при редком использовании в быту мне кажется, что просто старость их прикончит быстрее, чем штатное ЗУ. Вообще это не моя идея использовать старый зарядник. Я просто купил новый аккум у фирмы, которая занимается их переделкой. Говорят, что специальное под литий ЗУ не нужно. Дают гарантию год. Посмотрим что произойдет. В любом случае спасибо за ответ!
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?
E x c e l e n t e !
Thank you!
