(I already saw your link before it was excellent as a tip).
Sorry, as I do not understand English, I was mistaken for anyone to whom I must send it, so she arrived mistakenly sorry again. good night .
There are different 18650 cells. One type is optimized for capacity (e.g. notebook battery) and the other type for high current (e.g. cordless screwdriver). The cells for notebook batteries are often only certified for 2 or 3 amps and cannot deliver much more. Look at the datasheet for these cells. The BMS module cannot protect against current overload here. It is designed for much higher currents (here 25A). It is also not the task of the BMS to serve as a replacement for a charge control. The BMS is an emergency disconnection, which occurs in the event of charge control errors. NiCd and NiMh use completely different charging electronics. The chargers are not compatible with lithium cells.
Yes, you can convert the drilling machine to 18650 cells. All you have to do is: buy the right high-current cells, buy the right BMS for these cells, buy the appropriate charger and possibly modify the control electronics of the machine. Or buy a new cordless screwdriver with a lithium battery for a little less money :-)

I have the same project in mind but the original capacity of my batteries are ~60W, so I was going to use 6x 18650's (also about 60W) and I was going to use a adjustable boost converter to maintain the input/output to and from the 18650 balance board (so it can be charged and discharged at optimal ranges regardless of battery discharge). Finally happy to see someone used a BMS on their battery build.. most I've seen implement inconvenient and unsafe charging methods. Thanks and best!
Have you had a chance to put 6 cell into your battery house? I would be interested what kind of charging method you use.
Its strongly reccomanded a bms, without its what can hapend?
Saverio Mallardi Non-balancing charge circuits do not actively unbalance cells or charge unevenly. They just don't compensate for voltage differences which gradually accumulate due to very slight differences in the cells themselves. Mainly however, the BMS helps with charging. Without one, you basically need to charge them in an external charger (which has BMS technology in it). I want to use the multi-chemistry charger I already had, so a BMS is required so I don't have to pull the batteries out each time or have a separate lead and charger (which I just don't like).
monghuz Late response I know, but I use a multi-chemistry charger that came with my newer Craftsman set. so that I can charge my older NiCl batteries, newer Lithium batteries, and old "dead" NiCl batteries upgraded to Lithium 18650's. It's working good so far.
Thank you for your answer, i've recently changed, like this video, a battery pack ni-cd to li-ion, i used initialy 3 18650 3.7/4.2 volt but the charger gived me 17.5v more that 12.6 needly. for don't to risk i had included another 18650 for 16.8v total for stay more happy, if i'd included 3 18650 only with the voltage of the charger what will can happen Thank you again
My bettery is dead. I just need to change it. By chance, I watch this video. It is very helpful for me. Thank you very much.
It works awesome on my B&D 14.4VI used 4 cells and PCM battery protection board for 4 cell
Nice video... I was thinking about to change the batteries of my drill because I'm tired of NiCD self discharge problem. Every time I want to use the drill, the battery is dead and of course have a big memory effect, so the battery last much less than before.
With this trick the batteries will have no memory effect, and will have less self discharge and more capacity (you can get batteries of 3Ah and is much more than the original 1.2Ah)
First, great video. If you have a proper 12v charger for li-ion batteries will you still need the board?
Nice could you please let me know I would like to make 18v 1.5 or 2mAh which type board I will use and please send me connection diagram thanks a lot
Hello can thank you for this video. I want to ask if its safe to use 30amp bms on 20amp batteries?
i lost my 12v 1.5 Ah NiCd battery charger for my GSR 12-2 drill and I can't find the replacement for that charger.. any guidance ??
are you charging with Ni-cd battery charger ? what effect do you have on your Li-on battery ?! thanks !
he added protection and balancing circuit. it will cut electric when batteries are full.
What a fantastic way to recycle old lithium batteries I was going to throw out anyway.
Hi nice video i was thinking the same batteries that i could replace my nicad. But my question is can i use the batteries without the protection board i have a nicad charger with the incator of knowing when the batteries are full. Because i can remember that when its new with my nicad battery will go a fast charge and the battery heats up and then indicates full and the charger stops charging the battery when its full. Thank you for replying this video helps me alot
Can i use all batrei from laptop ? Composition same with laptop
I just replace with brand new nicads, like for like then everything is as it should. My last battery lasted me about 4 years so if it costs me say 12 to 15 pounds sterling every 4 years i'm fine with that, plus the newer nicads i replace my old ones with had more capacity, just that it takes a little longer to charge up to full. Sure, old drills with nicads are heavier but thats fine with me.
So that top NiCD battery gets bypassed, and is only retained for ease of installation?
boss, if I change the bosch 12v nicd battery to lithium ion, don't use the bms protector, can it or not..Is it damaging ... tq boss

Will this setup provide as much current (as hence power) as the original NiCd battery pack? Or will the voltage collapse under high load?
hi Jaakko
battery power is better.
follows the new generation of drills, all have li-ion batteries
@@CMCdiy I have a circa six year old Bosch professional series (blue) cordless drill with an 18V NiCd battery (fifteen cells) and the torque is awesome. The battery weighs 700 grams for the cells alone, perhaps 800 grams including the battery casing. The huge torque means that it is drawing high current from the battery at high torque, and it seems a little unbelievable to me that a little thing like that could actually deliver an equal amount of current :-) But I might try this because one of the two batteries I have is dead. I will have to use a four cell version of the Aliexpress board to get a voltage that is at least close to the 18V nominal voltage of the fifteen NiCd cells. One can also get the cells in Aliexpress cheaply, their quality will be a mystery though.
You good to show when you have all the parts !!!It is possible and not such to collect
I want to do the same for a 18 V Li-Ion batteries for my hitachi drills , should I use the same charger board sugested on the video ??thanks for your kind help
Hi, my cordless screwdriver does not turn up when I press quickly. Why is that? I have a Festool 12V and the same BMS as you. LG Sascha
Nice
How can we make another recharge for this drill because I losed my recharger
hi
in this case try this project
czcams.com/video/GBsUkEzfzhk/video.html
Grazie! Non si finisce mai di imparare
Wspaniała rzecz😃 Poland
If changed to a 12v li ion battery, can I use a 12v bosch charger other than a li ion charger ???
I have some concerns. 1. A NiCd charger is totally unsuitable for lithium batteries. 2. The old 12 volt NiCds were really 12 volts. Lithiums are 3.6×3=10.8 volts. The 12 volts is a peak reading off the charger and will quickly drop to 10.8 after breif use and stay near 10.8 for most of the discharge. Old Bosch 10.8 lithiums were later rebranded as 12 volt to compete with the competition. In Europe it is still 10.8 volts..Decent NiCds are 2 Ah and you can get almost twice that out of directly interchangable NiMh. What are these cells? If I were to go through all that trouble I would use new cells, not salvaged. They are not very expensive.
The BMS board he adds takes care of the charging, the NiCad charger is just supplying the power to the BMS board
Greetings: Indeed U R correct. However the idiots attempting this do not. Their bold lack of respect of lack of knowledge will become their demise. No worries. Society could use less respectful and stupidity.
Hello, i did this project but my Bosch Drill doesn't work when I push the button faster, looks like the BMS can't handle the instant voltage i guess?. If I push it slowly to the max it works properly. Where's the problem here?

bosch consumes over 10 amps, those batteries only resist to 2c, ie 3-5 amps
Hi lukacs.True what do you say
In the description we specified that if you want something profesional you can use High Drain Cells that have a much higher power at discharge
DIY Tips&Tricks or if you can fit it, just parallel another 3 batteries.
Then use LI-PO batteries instead LI-ION. Some batteries are able to discharge at 20A and some BMS can handle up to 25A.
@@Danixu86 samsung batteries have 10A or 30A continuous discharge. I've been looking at poly batteries but they don't seems to fit for this stuff. They would be probs better
@@XxXnonameAsDXxX Yeah, after research I've seen that is enough to use High current batteries like Samsung or two groups in paralel. I've recycled the batteries from an old laptop, and I've changed my dill NiCD batteries with two groups of three batteries from that laptop. After more than a month they still in 12.1v, and I've used the drill without problem.
Old NiCD batteries were always discharged and now the pack have more less x3 of capacity.
Low discharge batteries will not work well. you need high discharge batteries! Bet it runs flat quick.
Ignorant person with too limited knowledge. Wrong type of cells for motor that can draw up to 20 amps impulse. just a useless video. Bad isolation too. Highly NOT recommended
Ya i also my old cordless drill Bosch 18. Year old Bosch replacement like this but 3 battery no strong some more try again 6 battery 12v TQ Mr
Hi, I had done the same project like yours to my bosch psr 12 drill with my old laptop batteries li ion 18650. But when I try to use drill if I push full speed it starts to turn but stops suddenly. If I push slowly and speed up it works but batteries charge end in a few minutes like 5 minutes. Is it normal or I have done something wrong?
Cells of laptop are steady low current type. For drills a high surge type is needed like the 15Q or 30Q from samsung. Expensive cells. Motor draws up to 20 amps under load. Laptop cells can deliver at best 4-5 amps
Cells can overheat or even explode with near short circuit application like a DC motor
Hi. I have the same drill.
I bought new
batteries 2200mah. When i solder them together on bms board i think i have a problem.
When i pressing switch on a drill slowly she start rising rpms and work great. But when a try to press that button quickly she make one slow turn and stops. So i must start with a little bit slower rpms. When she start spinning there is no problem. She nave strength.
Btw, there is one small resistor in the battery housing. On the place which is connected to the one plus contact of battery (one plus contact is on left side, and other is on the back side) . Should i remove that resistor?
Ok, i watched video again from the beggining. I did same as you. Only difference is that i cut off those two thin black wires which i didn't know what are they for. Is that a mistake?
Here you can see the new video with conversion and the final test

@@CMCdiy So, the problem was in bms board. I was suspect on that, but i couldn't be sure. Thank you. I will order that model.
@@CMCdiy Can you also recommend me bms board for 14.4 V drills?
I need to do this with my old black and decker batteries. They just die too quickly. Thanks for the video
Hi, thanks you for an awesome video! Finally found an understandable way to give a second life to my Bosch PSR12... It works now, but as a screwdriver. I once tried it as a drill and 2mm in the wood hole with a 1mm drill it started giving a smoke and I could only start it once more and one could see like a fire inside the motor. Then it was just starting for half a second. After it cooled down it works again, but as a screwdriver.. Can you tell me what's wrong? I could easily drill before with Ni batteries. Now I have Samsung 2500mAh 25A 18650 batteries
And maybe one more question. I was about to change the second battery to a power transformer, but no idea which properties it should have, like power and amperage? What do you think? Would be super grateful for you help...
I think you should add 3 batteries more parallel to make it Stronger
2 years later parallel or series? Parallel would keep the voltage the same while series wouldn't and it would increase the voltage.
Hi DIY Tips&Trickscan i use the original ni-cd charger with the protection board?Thanks
Hi Christian PeterschmittYes, I used the original ni-cd charger, the PCB BMS Charger module will stop the charging.
See my blog for products which I used in this video:diy-tipstricks.blogspot.com/2018/12/how-to-convert-replace-ni-cd-to-lithium.html.
Thanks 😉👍
What if the current from original charger is too high? What regulates current and amper?
@@kresimirpranjic4898 The current of the original charger is too low (I think that 0.5A), and the batteries are able to handle this without problem. Even are able to handle much higher charge current, for example: 18650HG2 batteries are able to charge at 1.5A and up to 4A in fast charge. NiCD/NiMH batteries handle much less current and that's why they need about 8-14h to charge, while LiION can charge in less than 1h.
Can you do a video on a 8.4V Vacuum Cleaner converting Ni-Mh to Lithium Battery cos can find a good one on you tube.
Hi Sam
I don't have one at the moment, but I will try to get it and I'll make a video
Hello, I mounted the same Bosch GRS12-2 schematic, but I could not activate the board for output, can you help me? Thank you
I did not forget to like it !! ;)
Great, good info vid !!! :)
Thanks !!
Hi, what voltage does the module feed when it is being charged? How many volts and how many Amps?
Hi thank you for this video I have 2 questions:
1) what about the discharging...I mean lithium Ion Batteries must not be discharged under certain voltage. Did the electronics that you put control the discharge?
2) I have an electric broom and I would like to do the same. Is 18V - 1800mAh. I think it doesnt matter the capacity, it will affect the duration but about the voltage could I use 3.7V * 5 = 18.5V?
Hello. Luigi
1. You really need a charge-discharge protection for lithium batteries. you need protection for 5 cells, it's here goo.gl/7oFLhU.
2.True, cell capacity affects the operating time for your electrical broom. , and the voltage does not affect it because it is not too high above the normal value.
For high drain lithium 18650 visit goo.gl/h3xRKZ
Battery voltage: Li-ion
Over voltage range: Maximum voltage 4.2v 5 * 4.2 = 21v
Nominal voltage between 3.6-3.7V 5 * 3.6=18v
Over discharge voltage range: Minimum voltage 2.3v 5 * 2.3 = 11.5v
Thank you for the answer, just to be sure I have understood:
during the operation when the battery will be used for the broom i.e., will the bsm device break the current supply when the battery goes under the minimum voltage permitted (2.3V in this case)?
Hi, great job! I have made myself a 3s2p Li-ion replacement battery for my cordless drill (exact same model). All of the cells were precharged and balanced at 0.01 v diff. Hooked it up to the drill, when i press the trigger the voltage drops to 0 at the discharging terminals of the bms. The bms is rated for 60 amps max. Do not think it reached that high. The drill works fine with former battery pack. Rotor not in sort circuit. Can you please send your opinion on that could it be? Playing with it I have noticed that if I jerk the trigger really quickly it works on full throttle. No more voltage cut. But no low speed, only full throttle. :(
I think its because I have disconnected the resistor from the terminals of the battery pack. Could that be the problem?
Great video btw!
your problem is the BMS protection module, it is not suitable for drill,Here you can see the new video with conversion and the final test
czcams.com/video/FN0mx5n4ocA/video.html
is this last baterri on top old not used
can i use 3S 12V 10A Li-ion 18650 BMS? please reply
Older and less powerfull drills (the cheapests) works with 3s. But not this one, at least not for me.
could you fit 6 of them in there and make them 2x 3series parallel? would the same protection board be right?
Hi Luckma
Yes the protection module also supports 2 × 3.
But the two batteries that connect them in parallel will be of the same amperage
Hi. Can we use the same battery protection board and for 18v batteries? Or we need some other model? Thanks.
18V = 3.6V per cell = 5s battery pack, meaning 5 Li-Ion cells in series. You're going to need another BMS, because the one in this video is for 3s only. You can see that at 2:13
Hello, thank you for the tip, nice job, Mr you have change the first card recover from a chaegeur PC! she was not reliable .... ??? And you change it by another card that recharges 4 battery is that?
When the batteries are charging the new card stops charging the batteries. Thank you for answering me, good day.
hi Hamadi

After these tests, one of these projects is failed and the other one is good.
Work good?
Hello! Great video! Congratulations!
One question: using the board with protection board, can I use the old NiCd battery charger?
Yes. surely. the board stopped your charging. The old NiCd charger gave you only the required voltage
Richard, correct me if I'm wrong.. but if you you a balance board with boost converter.. shouldn't you be able to use the same charger? I have a similar project in mind. Thanks
Richard Driskill thanks! I researched it a bit and got details on what you mean. I'll adjust my project and thanks again, just needed a nudge in the right direction..
hello Richard Driskillbut if i have a batteries block Li-Ion and a charger for Li-Ion batteries do i need a protection board?
@@christianpeterschmitt2885 that's my question..did you had an answer?
Why did you Leave the original battery inside? Is there a specific reason? My second question is on my batteries of the drill it reads ni-cd 1.2v SC 800 Mah and in total there are 15 batteries so how many lion batteries should I use with bms and it must be bms 3 or 4? And it must be 20 ah?
probably because it holds all the connections together and is easier to hold in place with the hot glue.
If i change my cells would it change the amp hour thanks

mastmalang70hk,
If you suspect the battery is already dead, consider "shocking" it first or using another battery to charge it up.. then try it on the charger first before spending money and time on this project. It's fairly likely you can revive your batteries.
Usually one of these three things happen, in order of what you should try: 1) the battery has been discharged to much for the charger to charge it, in which case you can top it of with another battery, 2) there's corrosion or crystals forming, which can be broken up by high voltage shocking (watch a CZcams video lol), 3) your battery is actually toast (probably just one or two of the inside cells) in which case do this project.
Best!
Using cells from a laptop battery doesn't work because they are low drain cells, the drill will spin up but have very little torque and stop under mild load.
Hi I have a bosh drill it's days it's charging but when I put it back on drill it goes dead really quickly why would this happen.

Your bms is rated as 40amps max. But cells not rated for that. Did you use it or you just showed how to do it?
So the 3s 40a BMS should not be used together with 18650 cells (from old laptop battery)?

Should I instead use 3s 25A BMS:

With BMS and one 18650 Li Ion battery can i use the drill charger that have an output of 6 volts....the drill is rated 4.8 V

Hi Dear Friend, Could you help explain me How to make the same work, but with a 9.6V battery please? Thank you for your great help
Hi Gabo,
A charged Li-ion cell has the value of 4.2v × 3 cells = 12.6v, a unloaded cell has 2.5v × 3 = 7.5v.
A ni-cd, the maximum voltage is of 1.3v × 10 batteries = 13v. and discharge it reaches 0.80v × 10 = 8v.
Is no significant difference.
Help me out, i have the same BMS and drill. When the dril is rotating slow is ok. If i hold it it will go off. When I push the button full it's also going off. How to fix it.
Me too. Same batteries, board and drill. Too much torque and it stops (over discharge probably). Have to take out and put back the battery. I've ordered 3s40a & 3s60a to see if it helps! I tried the capacitor on the battery suggestion but that just froze the situation when it stopped.

scusami ho eseguito tutto allo stesso modo il trapano va bene solo se va sotto sforzo si ferma e nn va piu devo rimettere a caricare e cosi fa sempre cosa e dovuto grazie e come avrebbe una protezione
Hi Friends, here I want to correct a mistake or a deception. You cannot operate charged batteries with batteries from products such as laptops. Because rechargeable screwing is a High Amperage. Do not look that it works in idle way, You can not do any screwing When the tool comes into power, that is, when it starts to pull the required ampere is not enough to turn the screw can not turn. There are 18650 batteries produced for this job, for example, batteries that provide current (instantaneous 30A). Other than that, this battery will not work with anyone to fool anyone. you will see everything for yourself.
really? that tiny motor doesn't draw near 30A it draws max like 9 A when under a heavy load. + the BMS is 20A so you are pretty wrong there bud. if it would draw 30A constant when under a very heavy load the motor would burn out in an instant
IF YOU FAIL TO USE THE BOARD THAN YOU WILL DESTROY THE BATTERIES the first time you charge, Li-ion will not accept even .01 volt of overcharge voltage. The instant it goes above it's rated voltage it becomes a "boat anchor" . Charging Li-ion in series with no regulation is suicide

I guess batteries in parallel will share the current load. Better if using laptop battery cells.
laptopbattery is not suitable for high drain devices - that will cause drill work very weak or battery catch fire.
It does not work. Batteries from laptops do not have enough amperage to power tools. Yes, it may start spinning, but it will not e.g. tighten a screw
WHAT ABOUT THE OLD ONE BATT INSIDE?
STOP SHOUTING!! Use capitals only when starting a sentence or a name, please. The old battery inside does nothing as the poles are no longer connected, it is just kept in the drill to keep the leading wires in their proper position.

You can't use a 14.4v ni-cd charger for charge a 12.6v li-ion battery! It will kill your battery and is very dangerous
Very very very annoying music.
Czy widzicie ilu jest ludzi bez mózgu ja widzę prawie 4 tyś, którzy polubili ten film bo myślą że to takie proste .... ogniwa pozyskane z laptopa a wkrętarka śmiga jak nowa. Włączcie myślenie. To nie boli.
Come on. Why use such annoying background music? It’s unbearable. Instant headache.
Should of turned your volume down/off consider he hasn’t said a word for 6m lol
Dangerous. Don't do what this video shows. Laptop cells are not rated for such high current. Furthermore, ni-cd charger is not adapted to li-ion batteries. It should be modified. Risks are that the battery catch fire when Charging or that it explodes in your hand when using the screwdriver
Potwierdzam film jest szkodliwy.
Wielkie ryzyko pożaru przez wykorzystanie niewłaściwych ogniw.
İt is imposible to it with laptop batterys because their max discharge current is very low. You need at least 20-30 A discharge capeble battery for this kind of project. Please don't fool people
Нельзя использовать эти АКБ
Не будет работать, изолента черная.
that music is annoying

Pay no attention to this idiot "Richard Driskill" and his nonsensical ranting. This configuration, as shown by DIY Tips&Tricks works fine as shown in the video and is the recommended approach. If you see the original battery it contains ten (10) NiCd cells which are rated at a nominal 1.2 V after a normal operation full discharge. These NiCd batteries at full charge can reach as high as 1.37 but they start losing their charge immediately so an average value would be around 1.28 to 1.30 as a starting point. That means the tool is optimally operating at voltages between 12.8 and 13.0 V (e.g. the voltage of one battery X 10) but as the batteries are being discharged the output power/torque of the tool decreases. With LiPo batteries the optimal range is 3.0 to 4.2 volts or with a 3S pack from 9 to 12.6 V. LiPos are able to provide relatively steady power output over their useful discharge range therefore even at close to 9 V the tool will be useful, This is not the case when using NiCd , anything lower than 11.5 (or 10 batteries x 1.15 V) is not going to be useful plus you are destroying the cells. It is better to stay closer with the original voltage configuration so the 3S pack as shown here is the optimal solution.
Greetings: And how does he figure 12V from 3) 3.8V cells? Hmmmm. And U trust this? I know how he did it. CK my other comment.
horrible soundtrack
Couldn't stand that obnoxious music...
C'mon man. Get some decent background noise.
