Lithium battery charger $6, 18650 cells $18, BMS module $6 ...Your talent...Priceless.
spot welder, 3D printer
@@UGPepe u dont need 3d printer u can just glue the cells and spotwelder board costs like 20 or u can just solder the cells ik its not safe tho
Soldering the cells isn’t safe?
Wow, I have never seen such a super quality film here and it seems to be 4 K quality and the revision of the old worn batteries is TOP and even the manufacturer could not do it better. I would certainly entrust my device to him for the repair and you will not find many such perfectionist repairers.
I had three cordless drills - two of which were at least 13 years old -
and had been sidelined fro almost a decade
It was only a year or so ago that I had to repair a LiOn Battery in a
MAKITA cordless drill --
It was then decided to convert and re-pack the three Power tools that
were set aside - and convert them to LiOn
It certainly was better than dumping them.
I see many for sale at local Trash & Treasure markets - being sold for
the equivalent of USD $3 - unfortunately not many of then have the
charger to go with it -- so selling them after a modification has been
completed - makes it difficult to SELL sans charger
Absolutely superb battery conversion job👌
I have gone a different way to convert several of my old 18 volt Dewalt NI-CAD/NI-MH power tools to Lithium Ion.
I use the original NI-CAD battery top cover and battery connector and attach a slimline Lithium Ion adapter shoe directly to the original NI-CAD top plate.
This assembly of old top plate and Lithium adapter shoe is then fixed into the power tool battery port with 4 small self tapping screws and then a standard Dewalt 18 volt Lithium Ion battery can be fitted to all the modified power tools.
So far I have successfully converted an 18 volt cordless vacuum cleaner,a 165mm trim saw, a compact angle drive drill and a SDS masonry drill....all work very good on the Lithium Ion packs.
You can actually buy the complete adapter (very cheap) which is very good quality and also has USB out. Search Battery Adapter DM18D With USB, Compatible With Dewalt 18V Tools
Except that you may ruin your batteries if they expect a tool with part or all of the BMS circuit in it, since the Dewalt 12V/14.4V/18V NiCd tools had no such circuitry in them, and I am certain that "some" (if not all) Dewalt Li-Ion batteries in the 18V/20V families, do not have the BMS in them.
Very nice, well thought out conversion done to a high standard. Thanks for sharing your ideas.
This has to be one of coolest battery conversion videos ever! Super clean. Nice job! Liked and subscribed!
This is what I was expecting from conversion of the old ni-cd batteries to lithium-ion battery pack and the chargers requirements and how to fabricate such a charger. Thanks a lot.
Nice touch updating the charger too. A great updated drill at a great price, nice job.
Very neat and tidy video. Great content as well; especially enjoyed the effort you went to with upgrading the original charger.
Awesome instructional video! Concise, simple, and no drawn out "look how smart I am" speeches! Bravo!! I am 100% going to do this!!
Thank you for the instructions on the conversion process. Hardest part was following the battery wiring - parallel / series. But, I have my Ryobi 12v drill converted :)
Probably the best conversion O have ever seen with great detail !!
Top class video with very clear instructions. My tip for sourcing Lithium ion cells is to check out your recycling centre where these 18560 cells can be found in every tool battery also in hoovers and anything else using lithium batteries such as hoovers etc. An almost limitless supply of free good batteries.
During Covid-19 I found couple half used cans of interior white paint and I decided to paint the garage. I needed a 9v battery to test out something and found 2 good ones....all in our localrecyclecenter.
Brilliant work, dude! Nicely done!!! 😃
Stay safe there with your family! 🖖😊
That was purely a fascinating upgrade to lithium Ion. Your the best.
Best Lithium conversion project ever !
Excelente tutorial , sus conocimientos de electrónica son muy grandes , muy buena transformación , gracias por compartir sus conocimientos y experiencias , un saludo cordial y por supuesto un gran like desde Narón (Galicia) 🤓 🔝 💨
Very cool way to recycle a power tool that still had some life left in it! And it was way more cost efficient to make those modifications then buying a new drill set!
Where did you get the batteries from, that price seems really good to me.
Beautiful conversion!
I purchased a brand new Black and Decker 20v lithium impact drill/driver for $49.95. I know it's difficult tossing perfectly good tools with bad batteries, but still. I have other drills, but that's the only one I use now. It's powerful and changing bits is super easy. The money and time you spend to get the batteries and other parts and then assemble, it's cheaper to get something new and modern.
Excelente, tenía algunas dudas en renovar mi taladro 18v, seguí las instrucciones ocupe bms 5s y quedó perfecto 👌
Impresionante, lo ha hecho perfecto y con gran facilidad.
Very well done. Extremely informative & well paced
Have you posted the STL for the battery holder? Nice job on the conversion, it's good to put older tools back to use.
Good ideas and a great job! Very informative.
As much as i like fixing items instead of throwing them away and spending more money on replacements. Because would doesnt like to save some money. But in this case, i ended up just buying two battery packs for my cordless drill for thirty bucks. None the less, great video.
Nice and clean Recycle!
Wow. Nice work! Very well done.
Very nice! I have a similar Dewalt drill/charger configured for NiCAD cells.
Thats one awesome project! Thank you for sharing, great job and good explanation! You got a new subscriber! 😉
I upgraded my old cordless drill with 6S Li-po Graphene battery and brushless motor . the 18V Ni-Cd battery was dead long time ago and the brushed motor was gone. Now I have brand new top notch drill with invested 100 bucks and few hours work.
Thank you very much for this educative video.. Well Done
Nice job once again. If I have time I'm gonna see if I can do it. Providing I have all the parts still.thanks
Good job
İs it possible to see your spot welding(how did you do that)
Man, that's what I call a CLEAN WORK. Well done! Thanks for sharing.
Even being a layman, I have enough tools and I'm definetely doing it soon.
Instead of the lithium battery charger you've used, could I use a normal 12.6V power supply?
If so, which could be the minimum amperage for a 3S2P pack?
Thanks again. All the best.
Those stickers at the end killed me! Yes. I will never try to fix anything again! Thank you?
Very nice tuto, great thanks.
Long ago I also took apart an old battery but I just replaced the cells with the same chemistry and spot welded together. If I knew I could upgrade to lithium I would would have done so.
Very cool 😎👍👍
How did you make the sticky labels? Did you order them, how?
Very good job, the cells are high discharge ? or are they recycled from Laptop?.
I did a similar job (But not as good) for a Dewalt 18V Drill and only 5 cells (21V) fit in the case, using a 5S 100A BMS from the silver ones.
And I did exactly something similar with the charger using a 24V Printer transformer, but it must have a protection circuit because it deactivates 0V when connecting the battery, I have to do it several times. Greetings from Venezuela
I'm not sure what's a more obvious giveaway of the age: that it's a Ni-MH battery, or that it's got screws so you can easily open it.
Amazing video, and just the information i was looking for! Could you please also specify what spot welder you are using? I don't have one, or access to one.
congratulations for the work done, could you recommend me a link to get some batteries to do the same change?
Thank you
Great video, nice tips, would do it too for my oldy but goody DeWalt DC981 ... BUT ... am too scared of fire/explosion of Li-Ion batt's. If something burns in ''3S 40A BMS'' overcharge protection might be disabled and than BIG BANG. While if the fire breaks out in the Li-Ion there is literally nothing you can do to put it out. I do a lot of handy work, sometimes charging in the house, in the shed also in the room or adjacent room, where I work, so ...... rather no Li-Ion. Will go with 1,2 V LiitoKala Sub C, 3500 mAh, Ni-Mh and sleep tight :).
Very helpful video. I like your battery spot welder. Were can i get one like that from. Regards
Excellent videos ! 👍
Awesome job!
Nicely done
Increíble cambio ,justo eso le pasa a mi atornilladora,felicitaciones
Really god !! Thanks for sharing.
Very nice.
I did the same thing with battery pack, and charger for my old Black n Decker Drill and charger. (People make fun of the brand; but, Hey! it works!)
I used batteries from a Dewalt 20v. One cell was bad out of the pack.
I also used a cell to replace the battery in my NON-Repairable electronic cigarette.
Never toss Lithium Ion Battery packs; There is a use for them!
Make something!
Looking like witching neat and clean electronics amazing
great job thank you
great video sir, I have the same drill with the battery no holding charge , So i will do the same Conversion. I think the battery Circute board will over-heat if using continuous drilling.
You make it look all to easy
Super talented!
Creative video, thanks for sharing :)
excellent well done 👏🏾
Kolejny dobry pomysł aby usprawnić elektronarzędzie któremu padło zasilanie
Cool video !!!! Can you do this with the 18v DeWalt ,and provide links to all the parts?
I am about to do this exact repair on my dewalt, exactly like the one in the video.
Do you mind sharing the exact parts and numbers that you used?
Excellent!!! Thank you
Actually, he replaced the old nimh (nickel metal hydride) battery. Not nicad
Elinize sağlık
Awesome importation. Thank. I’ll do this for my stack of 18v & 14.4v dewalt batteries.
Real cool. Great respect
Hi, really interesting video, your drill/battery/charger were at 12.5v, I have a Bosch 14.4 volt drill and I have found on eBay BMS module 4S rated at 16.8v, assuming 3S is not able to cope with 14.4 volt, am I correct to use the 4S ?
Hi. Do you have a sketch of the holder for the batteries, please? Well thank you
Excellent!
Nice idea, but u shouldn't remove all part in old nimh changer and use this new lion changer. It changer 5ah battery really really slow (about 0.8-1A) and not safe for battery.
Good job 👍🤠
After you had bms on battery pack what will happened if you charge with original charger ?
I added a female adapter to my battery so you could use the wall wart to charge the battery. Much easier. Great video in converting!
This is great and exactly what I've been looking for. By chance can you post or send me the STL files for the printed battery holder parts?
Do you provide this as a service? For other brands
Brilliant, I’d like to try that, but it’s kind of intimidating if you’re not a pro like you
Do you have a video converting older 18v Ryobi Ni-Cd batteries? That would be so awesome if you do, please make one if you can, thanks and great video!
Awesome , good work,
Well done 👍
Great video! Very, very helpful. I wonder if you know how I can charge Li-On 18/20V power tool from a vehicle (12V supply without using an inverter? Can I modify a charger to be powered from 12V rather than 240Volt? PS Loved your mini bar build - I am going to do one of these for our camping trips and fool the Mrs.
how I can charge Li-On 18/20V power tool from a vehicle (12V supply without using an inverter?
1) use a BUCK converter to 'up' the voltage
2) use a battery charger CIRCUIT to charge the battery7
better to rebuild with nimh batteries which are also high capacity and still use the original fast charger.
Do NImh last longer than lithium? The nimh in this video lasted 11 years.
Muito bom
Awesome !
Real Men stufs... Thanks Bro.
شكرا لكم اخي
Una BMS 3S de 40A no es demasiada corriente para la descarga? No seria mas recomendable una de BMS 3s 25A? Gracias y gran video
Compartirías el stl del modelo de las pilas con la inserción de la bms ? 😊
Tradu în română
@@stefanvarlan9256 Nu este un 40A BMS 3S prea mult curent pentru descărcare? Nu ar fi mai recomandabil un BMS 3s 25A? Mulțumiri și mare video
Vrei să împărtășești stl-ul modelului de baterie cu inserția bms ? 😊
CAN I USE 5S BATTERY PACK ?? CAN THE 12V DRILL HANDLE 20V ?? FOR ME 5S BMS WITH CHARGER IS EASIER
How did or what you used to spot weld the batteries?
Very good
Nice conversion :-)
Most NiCad battery packs have a thermal fuse that goes bad. If you compare positive to negative on a good battery and a bad battery one of the terminals on the battery will not show voltage.
So intelligent & talented sir what is the price of entry to send my old packs and charger to you and your upgrade fro them to the @15v level?? seems so easy but we all learn by doing but you have backend stuff we do not. Thanks
Nice video a diagram would of been cool, since the important, most intresting part was not shown totally.. the wiring of the batt wasnt shown rite, wish u would of spin o turn all around to see all the detail of the soldering u say parallel, but i was only able to view how 4 of 6 batt was spot weld. 2 batt i wasnt sure of🤔. where they bridge to the rest of the batt or soldered directly to the board??
Can you give a link to the model for printing the 18650 battery holder? pls
Awesome
Awesome!!
Great!
Could you share the STL files for the holder for the battery . Thank you
What would happen if the new li ion battery pack is plugged into the origainal ni cad charger? EXPLOSION???? The internal BMS won't prevent that from occurring?
Pervect ..... Top !
I followed your instrction but got some red light on the bms like unbalance batteries works for a few seconds and drain the batteries indicates they are charging but same result any ideas that could help
Thanks
Could I use a power bank module as a usb charger for this?
