Cordless Drill Conversion - With Laptop Batteries??
HTML-код
- Опубликовано: 12 окт 2018
- In this episode I will convert my cordless drill battery from ni-cd to lithium ion cells salvaged from laptop batteries. It's very popular on RUclips and I want to see what the fuss is all about. In reality it's very dangerous... so be careful if you try it.

Wo, wo, wo, woooo!!!! This is quite heavy duty super SPECIAL STUFF!!!
This has got to be one of the best cordless drill battery conversion / repair I've ever seen here on RUclips.
Thank you for this precious information.
Greetings from Portugal.
This is the most comprehensive presentation of a power tool battery conversion that I've seen so far.
"I played with it for another hour and got bored, so I tied it up" - Great video and hilarious quote :)
Thank you for taking the time to do this video. It's nice to watch someone that knows what he is doing.
finally, someone who knows what he is doing :)
You bet 👍👍
Totally agree. Ive seen a lot of magician RUclipsrs tonight. Congratulations!
Very good. I like the fact that you mentioned the limitations of everything including the BMS. It saves a lot of trouble.
I must definitely say that it was the best drill conversion video I have ever seen on RUclips. Well done! 👍👍👍
I have seen every possible video on battery conversion for drills, and I must say your's is the best so far. Thank you for this long and informative video. I am in the process of bringing my hitachi impact driver back to life and this will help beautifully.
Very comprehensive. Your clear instructive expressions were understandable. I often wondered about the purpose of BMS boards in reconstructed battery packs. The technical information made clear the inherent problems with Li- ion cells. Thanks.
Hey brother, you just got another subscriber. Really appreciate how you kept the music at a reasonable volume and gave a detailed account of every step you took in the process of your modification. Look forward to watching the next video on how to build a charging system that can deal with old 18650 batteries. Cheers
THE BEST NICAD TO 18650 CONVERSION TUTORIAL VID ON THE NET!!! THANKS SORIN.
Finally someone who isolates stuff! Thank You sir, you are doing a good service.
Petty, many "exposed terminals" videos are more than 1 million views and this is not.
excellent guide, clear and very easy to follow explanation. i really like how you explain the details and the limitations
I’m glad you actually know what you are doing, unlike some other DIYers on RUclips. Also, you’re the first one that actually solders the cells quickly 😁. I use a DIY spotwelder, but I always see people mentioning that you shouldn’t sink much heat into the cells and then they proceed to solder on them for 5 seconds 🤦🏼♂️.
Nice work, wow very detailed and covering all the bases!
This is the first video I’ve seen from you. Now I’m binging. Fantastic
this is the best I have seen on you tube,well done
Very nice job Sorin! Explanation very clear. Thanks
Thank you, Sorin. Very clear explanation.
Hi Sorin ,Thanks for this new project that i am waiting for a long time , gd to see u using a simple solder and much simple circuit
to make it work like new.. tks pal
Sorin, you are definitely a genius!!! Subbed!
Excellent done Sorine, bravo! And thanks, will use your tips very soon for my project.
(
Hand down, best video for the drill conversion.
Awesome video, brother! Thank you kindly for your time and great info!
Bravo Sorin!
Super informative & clearly explained, lovely video bro! Thanks !
Good video. I am dabbling a bit with old laptop batteries these days so this info is very useful to me right now. I figured quite a bit out so far but the amount of drifting surprised me.
Faci o treaba grozava Sorin!
This video so helpful and the explanation is so clear, thank you
Another great video .Finnally somebody makes the things properly ,preventing the "nerds" from beeing exposed to hiden dangers.
Congratulations
great video and even better explanation. you really know your stuff welldone
Wow! Really infomative and very useful. I've subscribed, thanks fior sharing Sorin. Greetings from Southport UK.
My friend this was very informative video, someone who knows what you doing keep up with good job.
I LOVE YOUR VIDEOS ! This is called that it does this and if you do this it will do that!
short to the point no "unnecessary information " Just Well Done Videos
keep up the good work Sorin! I can really learn from you!
"now it have enough power to hurt my hand"
😂😂😂

Well explained!! Thank you!!
Very informative, thank you
Awesome. Thanks for sharing
Bravo, bravo, bravo 👏👏👏👏👏
You are always right
Excellent work. u have a new subscriber.
Great video very informative thank you for posting
Thank you !!!
Very nice bro
There are also shops which offer battery cases and PCBs for cordless tools which run already on LI-Ion batteries, for example the Makita LXT sytem. Combined with salvaged high current cells from tool batteries with broken PCBs (can also be packs from other brands) you can get extremely powerful packs, which are on the same high power level as the original battery packs. It is important to use high current cells in this case, because only them can deliver the currents tools like angle grinders or cordless chain saws need.
Ty bro.. rly good video. Good explained.
must admit he know what hes doing and whats what
good presentation
Beautiful hardware hack. I just found your youtube channel. I couldn't click subscribe fast enough. Thanks.
Excellent!
Very nice sir
Thanks pro , but we are need video about your soldering iron how you made it ?
Thank you. I will use the same principle to rejuvenate my iRobot Roomba's NiMh battery. It is also 4s2p.
U are the best big thanks
Bravo!!! 👍👍👍
Thankyou , I have been curious of the balance chargers as I use the 18650 in my Bluetooth builds and just recently had to buy a bunch of new cells , their not cheap and wanted to get the most life out of them ..:)
thank you very much. it is just what I was looking for. I'll let you know how it works after getting stuff from banggood.
Very nice good job
Nice Battery pack
the most professional way to convert nicd to lithium battery
exellent video, very helpfull, thank you
Excelent video. Nu sunt pasionat de electronice insa tutorialul e foarte didactic chiar si pentru "profani". Astept si alte filmulete
Bravo man :D>. imi place ce faci :).. esti tare :).,
Nice tutorial. But often, it is those cheap BMS and controllers that goes out first. It is usually why laptop batteries are dead in the first place. Instead of soldering all the components in the battery, just extend the balancing cable out. You can make a small magnet door on the battery to hide it if you want to look neat. Then modify the charger to connect to balance charger like Tenergy or Imax B6. And just connect the balancing cable.
Lol...the automatic draining got me good
very useful, u don't waste my waste thanks
thank you Sorin for sharing your skills. Your accent ads color to the video but overall, nothing wrong but it is overall an excellent. please make more educational videos. thank you..
I have a couple of cordless drills that I am going to try this with at some point. It sucks that the replacement batteries cost just as much as the drill was when it was new.
Thank you for this great video with this info. about converting to lithium batteries on these cordless drills.
If your drill 2x more powerfull just make 2x bigger battery. For example S4P4. I used 3S4P for my old makita drill with old laptop battery cells.
Awesome
Hi Sorin, I made similar modification like you, but my drill is stopping when accelerate. I used 3s 40a bms board and battery pack in 3s2p configuration. Dril is BOSCH GSR 9,6V VES-2. There was a small resistor on the battery + - connectors i cutt it out, but i think should stayed there...Thanks.
You should be hired by companies
1:30 I experience the same issue with my DIY dremel, when I connected it to my ATX Lab Power Supply (thx, I used your "Gorgeous" ATX Lab Power Supply project). Additionaly, I added a XL6019 LM2596S (Amazing StepUp & StepDown Module) to get some variable feature other than 3.3v/5v/12v. Sometime I need less than 3v, to test 3mm Led for example.
My DIY dremel is build with an old 555 motor, it was for a drill I guess.
So alternative is to connect it to 5v, then step up voltage till reaching the speed desire!
Thx for the explanation, why ATX is shutting down... I did not use the trick with dummy load as you cause I do not have access to a variety of those ceramic resistor. But after learning, how useful they are, I started to collect some of them...
But wait , at the end you are charging the battery pack with an ordinary 12v charger! this white charger you are using is not for litium cells. What about when the battery are fully charged?? This charger will not cut off?? Is it not dangerous for the cells to be constantly chaged??
Because I learned that BMS is not actually a proper charging board, it is a protection DISCHARGING board!! yeah some BMS got over charge protection, but still they are not proper charging board for litium cells...
hi. it depends on the BMS board. if you have a CC/CV charger or converter + a good BMS board with balancing feature and decent voltage values for the overcharge protection and the other features, it should charge the li-ion cells good enough and not damage the cells. the charging modules for one cell (4.2V) are better, because they are more precise and it's easier to apply all the protection features to only one cell. it's difficult to do the same think with several cells in series.
@@Sorin_DIY yes you are right, though, I think it is easier to use 12v charger for Lithium battery, like you used with your first Router UPS.
ruclips.net/video/IlEnEn7ptmc/видео.htmlm54s
You right it is much easier charging a single 18650, but when you switch to 2 or 3 especially in series, thats when things start to be tricky and complicated.
wow......very nice vedio
Perhaps you remember the step up converter part number 🤔
excelente no entiendo ingles pero lo hice al pie de la letra y me sirvio, gracias
Future video... Waiting...
Nice summary of others videos,
1-But are you sure the BMS make the full charging process : Constant current until 4.2V/S, then Constant voltage untill current goes to 1/10th the charging current then stop charge ? Because for what i've seen these BMS are mainly made to avoid under and over voltage and disconnect the battery from charger or charge when it happens (needing to remove the charge or the battery to reset)
2-how and where do you set the charging current ?
3-what is the usage of the 2A step down converter you put in links
hi. in the BMS specifications it says CC/CV. when the battery pack is getting almost fully charged, the charging current decreases from 0.60A to 0.25A. so theoretically it should have some kind of CC/CV charging. to be sure, you need to connect a volt/ammeter to a single cell, and monitor the entire charging process. the charging current is set by the BMS. if you want to limit the current, you can use a step up/down converter with current limiting potentiometer, added to a 12V or 24V charger. if you don't have a 12V charger, you can use the standard power drill 24V charger + step down converter from the link.
Bine explicat clipul insa as avea mici sugestii, de exemplu ar fi mai eficient sa folosesti un step-down cu un incarcator de 24v sau chiar refolosit cel de laptop, daca ai fi avut mai mult spatiu putea fi inclus in carcasa bateriei. Daca nu ai facut pana acum un spot welder din transformatorul cuptorului cu microunde ar fi fain sa vad unul bine pus la punct si sigur explicat de tine :D tine-o tot asa!
salut. dupa ce am facut clipul, am incarcat-o si cu incarcatorul ei original de 24V + convertor step down. este ok si asa, singura diferenta este ca nu se mai incinge convertorul de tensiune.
Mi-a placut coversia. Cred ca ar trebui sa te mai "aliezi" cu cativa pasionati de DIY ca sa ai posturi mai dese ca altfel uita lumea de tine. De asemenea, nu ar fi rau sa faci cate un review din cand in cand la modulele/sculele pe care le folosesti si sa explici cum se folosesc corect. De asemenea, nu ar strica si un canal de discord unde poti sa discuti cu oamenii si sa raspunzi la intrebari cand cineva are nelamuriri. Toate bune!
Thaks a lot, you are literally saving lives or burnt skin at the least 😂
"Someone who knows what he is doing" I saw this quote and I totally agree.
Very informative and technically-correct video
I'd be interested in an update after 3 years.
Are there any lessons-learned after 3y of using this?
Anything you would do differently?
I'm going to convert my old battery-drill based on your video
thanks so much and keep up the excellent work,
ChrisV
hi. I used and charged the drill a few times, but eventually the lithium cells got very unbalanced, because they are not made for high currents. so you need high drain cells and a BMS board with a higher balancing current like 100mA.
What is your recommended minimum discharge current of battery to be use for power tools.
I have exact same no-name chinese battery drill. But when I opened up battery pack, there was only four cells inside! Battery pack with mostly empty air! No wonder drills were so cheap
Thx for the information. Great explanation and video. I want to do the same to my old 18 volt drill. Could you please tell me which parts would I need for this project? It would be with a 5s BMS..
hi. you can use this type of BMS:
