spot welder, 3D printer

[@dendys04]

@@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

[@blueback21]

Soldering the cells isn’t safe?

[@maikeljwt]

@@blueback21just watch out u dont bring too much warmth into the batterie cells. It will damage it

[@Education-yk5ug]

So 6+18+6=$30, plus effort. vs. replacement battery ~$20. Is it worth it?

[@howardosborne8647]

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.

[@battmanbattman5308]

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

[@stinkycheese804]

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.

[@wimpraet5161]

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.

[@andrew_koala2974]

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

[@Ivan-Archer]

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.

[@welbyroberto6581]

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.

[@ryanmacewen511]

This has to be one of coolest battery conversion videos ever! Super clean. Nice job! Liked and subscribed!

[@lwh7301]

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.

[@kevvyg04]

Probably the best conversion O have ever seen with great detail !!

[@MotogiantTL]

Awesome instructional video! Concise, simple, and no drawn out "look how smart I am" speeches! Bravo!! I am 100% going to do this!!

[@viswanathanramakrishnan7613]

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.

[@gjt2209]

Very nice, well thought out conversion done to a high standard. Thanks for sharing your ideas.

[@divyajnana]

Nice touch updating the charger too. A great updated drill at a great price, nice job.

[@EmmAyeVee]

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.

[@georgivoyvodov1123]

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.

[@ksfurlover2]

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 :)

[@Fierofreak01]

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.

[@xtndz3320]

Excelente, tenía algunas dudas en renovar mi taladro 18v, seguí las instrucciones ocupe bms 5s y quedó perfecto 👌

Have you posted the STL for the battery holder? Nice job on the conversion, it's good to put older tools back to use.

[@thisisyourcaptainspeaking2259]

Very nice! I have a similar Dewalt drill/charger configured for NiCAD cells.

[@manuelruiz1854]

I really enjoyed your video, THANK YOU for your time making it!

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.

[@VarHar-x1k]

Lithium ion battrties must be voltage and current controlled during charge period.

Brilliant work, dude! Nicely done!!! 😃 Stay safe there with your family! 🖖😊

[@jenntek.101]

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!

[@drchan5893]

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.

[@mjc0961]

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.

[@marcosramirez385]

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.

[@gabrielhoy6790]

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.

[@jured7383]

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 :).

[@hippie-io7225]

Beautiful conversion!

[@joseluisprieto3438]

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.

[@TL50-r9f]

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.

Why using a battery charger instead of a 12,6-13,6 Volts power supply? BMS is a charger itself.

Yes! I asked this question too. By the way, could you explain to a layman like me how I could know if the battery is charged using just a power suply? Is there a way to solder one green and one red LEDs somewhere? Where would it be? Thank you

[@xanadusanson621]

Hello friend, I don't know much English, but I will try to explain my problem: , I tried to change the battery of a 14.4 v drill to lithium, I used recycled 18650 batteries (obviously tested and with the same voltage) and formed a 4s2p pack and bought 4s bms boards at 40 amps (balancer type), and on three occasions the plates did not withstand even a vacuum test: (without effort) I thought it would be a defect in the board but I ordered from another store and now that I tried a new one and did a vacuum test performance, suddenly I heard a small explosion, I ignored it and continued drilling, until I heard a second one so I assumed that something had happened in the BMS and yes, a mosfet exploded and the truth is physically you can't see anything else but I think that more than one component must have been damaged as well. In your videos it looks so simple (and it really is, it's not very scientific) and this is happening to me, I only did a vacuum test on the other boards and apparently the transistors that are responsible for balancing the cells are heating up too much ( one or two, not all) and when I load them with the imax6 I get "connection break". Can you explain to me what I'm doing wrong or what causes could cause this to happen or at least what should I do? I thank you in advance.P.S: There are more details to explain but I didn't want to go on too long, if you need more details let me know

[@jeffstone7912]

[@marklangley1122]

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 ?

Why is it needed to modify the charger? BMS is charging/discharging the Li-on batteries the proper way.

[@stinkycheese804]

This does not make a lot of sense, that if you already had a complete charger, you might as well have just left it in the original enclosure and ran the power (output) cord into the base of the original charger. No need for the glue job you did which may also fail later, remembering that the PCB is going to get hot and that tends to degrade glue. It is especially significant considering that your adapter board handles AC mains voltage on it, and also that the charger board didn't look like a particularly good/safe designed product to begin with.
