Cordless Drill Conversion - With Laptop Batteries??
Вставка
- Опубліковано 12 жов 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 UA-cam and I want to see what the fuss is all about. In reality it's very dangerous... so be careful if you try it.

"I played with it for another hour and got bored, so I tied it up" - Great video and hilarious quote :)
finally, someone who knows what he is doing :)
You bet 👍👍
Totally agree. Ive seen a lot of magician UA-camrs tonight. Congratulations!
This is the most comprehensive presentation of a power tool battery conversion that I've seen so far.
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 UA-cam.
Thank you for this precious information.
Greetings from Portugal.
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.
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.
I’m glad you actually know what you are doing, unlike some other DIYers on UA-cam. 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 🤦🏼♂️.
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
Very good. I like the fact that you mentioned the limitations of everything including the BMS. It saves a lot of trouble.
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.
I must definitely say that it was the best drill conversion video I have ever seen on UA-cam. Well done! 👍👍👍
excellent guide, clear and very easy to follow explanation. i really like how you explain the details and the limitations
Thank you for taking the time to do this video. It's nice to watch someone that knows what he is doing.
THE BEST NICAD TO 18650 CONVERSION TUTORIAL VID ON THE NET!!! THANKS SORIN.
"now it have enough power to hurt my hand"
😂😂😂

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
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
Very nice job Sorin! Explanation very clear. Thanks
Excellent done Sorine, bravo! And thanks, will use your tips very soon for my project.
(
Thank you, Sorin. Very clear explanation.
this is the best I have seen on you tube,well done
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.
Sorin, you are definitely a genius!!! Subbed!
Awesome video, brother! Thank you kindly for your time and great info!
Another great video .Finnally somebody makes the things properly ,preventing the "nerds" from beeing exposed to hiden dangers.
Congratulations
Super informative & clearly explained, lovely video bro! Thanks !
This video so helpful and the explanation is so clear, thank you
Hand down, best video for the drill conversion.
Wow! Really infomative and very useful. I've subscribed, thanks fior sharing Sorin. Greetings from Southport UK.
great video and even better explanation. you really know your stuff welldone
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!
Faci o treaba grozava Sorin!
My friend this was very informative video, someone who knows what you doing keep up with good job.
Bravo Sorin !
Thanks pro , but we are need video about your soldering iron how you made it ?
This is the video like that can help the world to build easier, i give one of d top 10 categories rank in youtube.
why do all love all ur videos ?? :) Thanks, thanks for sharing.Its really awesome :)
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.
Very nice project bro!!
I'm learning.
10 out of 10! thanks for taking the time to put this all together. So much excellent detail and presented so clearly. Subbed
Muy claro, fácil de hacer y muy bien explicado, congrats!!
Well done sorin
Excellent project 👍 👍
Very detailed video 👍
good job . great work .
Great video
You are always right
Great Video with Great explanations! thanks a lot
Well explained!! Thank you!!
Awesome. Thanks for sharing
Awesome video!!!!!!!
This is a great video you should have way more subscribers!
New subscriber and I am going to watch all your videos...I like it
Thank you !!!
Thank you. I will use the same principle to rejuvenate my iRobot Roomba's NiMh battery. It is also 4s2p.
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 informative, thank you
Great video very informative thank you for posting
Excellent work. u have a new subscriber.
GENIUS .
Ty bro.. rly good video. Good explained.
good presentation
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.
Bravo, bravo, bravo 👏👏👏👏👏
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.
Beautiful hardware hack. I just found your youtube channel. I couldn't click subscribe fast enough. Thanks.
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 ..:)
must admit he know what hes doing and whats what
Very nice bro
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.
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.
Excellent!
Hi. Thanks for the video. I replaced the old batteries with lithium ones. I just connected them as + to - and I can not charge the unit with the original charger. Why? Is the connection method problem?
Very nice sir
Thanks for the video! I am learning all of this stuff, its fascinating. In the video at 4:04, upper right of the screen is some sort of gel-looking stuff that you dip the solder into. What is it? I have seen many videos with it? Do I need something like that for soldering? Completely ignorant of all of this, sorry :(
hi. it's soldering rosin. it helps the solder bond with the surface.
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:
www.aliexpress.com/item/21V-100A-BMS-5S-Polymer-Li-ion-Battery-Pack-Protection-Circuit-Module-PCM-18650-Li-POLYMER/32844842468.html?spm=a2g0s.8937460.0.0.7dee2e0eO2J0QY
exellent video, very helpfull, thank you
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.
Thank you for this great video with this info. about converting to lithium batteries on these cordless drills.
Bravo man :D>. imi place ce faci :).. esti tare :).,
Hi brother, I need to know how I can charge and what charger can I use?
I can't use the original charger thanks for everything and regards
Lol...the automatic draining got me good
U are the best big 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..
Very nice good job
Nice Battery pack
Perhaps you remember the step up converter part number 🤔
the most professional way to convert nicd to lithium battery
Bravo!!! 👍👍👍
Excelent video. Nu sunt pasionat de electronice insa tutorialul e foarte didactic chiar si pentru "profani". Astept si alte filmulete
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.
ua-cam.com/video/IlEnEn7ptmc/v-deo.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.
I have the same exact drill with a different name, where can i find batteries?
excelente no entiendo ingles pero lo hice al pie de la letra y me sirvio, gracias
very useful, u don't waste my waste thanks
Hello I had a skil drill with a dead battery and I put it to re-peak on my tgy accucell 6 and now it works buy turnigy accucell 6 and it should work
J sucsedeed to make finaly it need exetacly 12.6 v but when pusch gass at full atright direction sometmes just stol on left direction fork fine .why this do you know
@Sorin Hi, I have the same problem with the powersupply. I have a portable compressor (I can not measure the resistance) the motor spec is 12V 120W. Will the 2 1ohm resistor work, or I should increase the resistance. Thanks.
hi. what exactly do you want to do? you want to convert it to a PC power supply?
Great tutorial and extremely well explained but I have one question: why can't I use the old charger? In the end it is just a transformer that delivers a voltage and an amperage. I could use a voltage stabilizer if needed. Can you pleas explain this part as nobody on the whole internet (a little exaggerated maybe) is able to explain that
hi. the original drill charger has a different voltage than what the new BMS needs. but if you modify it or use a DC converter to stabilize the voltage, you can use the charger.
U can replace and i have this in makita dewalt and Milwaukee tools So?
