[@visl7146]

Good project but not useful if you drill and screw all day,it adds too much weight. Even with normal batteries,let's say an impact drive is more than 1kg...with this pack more than 2kg. And also if it slightly increases speed to the tool it will deteriorate the bits faster and more damage to the gears. Maybe I am wrong as I don't know much about electricity

[@Solipsfilm]

@@sreekumarUSA Thanks for your kind words! Luckily I have a better spotwelder now that I can plug into mains power, but the car battery definitely helped me out when I was doing this project 😆

[@holeinthesest]

Just a safety tip. When removing your car battery, always remove the negative connection first, so that if your metal ratchet/wrench touches another metal part of the car, you aren't shorting the positive to ground. This is the same reason you should always connect positive first when putting the battery back in.

[@igorordecha]

Oh I never knew why you should do that. That makes sense, thanks

[@Solipsfilm]

Interesting indeed, never thought about it this way! Thanks for the tip :)

[@KenPiper]

@@Solipsfilm Yeah, first time I was working on something with my vehicle's battery, I learned that lesson first-hand. Now I've got a ratchet with a melted spot on the handle and a matching melted spot on my alternator mount... Turns out that a battery rated to put out almost 900 amps can do some damage to steel real fast!

[@DarkLinkAD]

Many dealership mechs failed to practice this on Toyotas, which blew the 120amp fuse, thats not easy to remove/replace.

[@Teklectic]

The stringy-nes of PETG can be mostly eliminated by dehydrating the filament and keeping it dry, it's a very hygroscopic filament and when it absorbs moisture it gets stringy and the resultant prints tend to be more brittle than they should be. I print a lot of stuff in PETG and have had good success with dehydrating in a regular food dehydrator at about 70C for about 8 hours, afterwards I put the filament into my dry box (plastic box with desiccant and a hygrometer) and print from the dry box directly; I get excellent results this way with very little stringing.

[@thesloppyapprentice2528]

Excellent design! People just don't get how much time goes into designing a 3d model like this, especially with non engineering software, and filming the process is another story..... it takes a real enthusiast. Keep up the good work!

[@Solipsfilm]

Thanks for the nice words! It definitely wasn't as simple at it looks in the video, there were a lot of blood, sweat and tears involved before I got it the way it is now 😅 And using 3Ds max didn't help the case indeed.. I'm learning fusion 360 at the moment whenever I have some spare time, and that's also the software I'm using for the next project.

[@Debbiebabe69]

@@Solipsfilm what a lot of people (who have never 3d printed) dont realise is that buying and setting up a 3d printer, perfecting printing and slicing, knowing how to configure the printing parameters etc. is about 1% of 3d printing. The amount of people (I would say over 99% of 3d printer owners, including owners of high end machines) who have the 'perfect' setup but their printing is limited to printing out Pokémon off thingiverse and other similar trinkets is amazing. Actually designing things to print, popularly known as 'CAD', is the BIG stumbling block in 3d printer use, and most people who buy a printer and throw it in the garage never to be seen again after a couple of months do it because they cant use CAD. CAD for 3d printing is the same as CAD for subtractive methods (milling, drilling, lathework, etc). There are basically 'lego brick' entry level options, mostly websites but also the popular games 'Minecraft' and 'From the Depths' which have this feature, but all of them have the same problem - you are designing in blocks, so all you can print is blocky things. Above that there is fully featured CAD software such as 3dsmax, fusion360, and freecad, which pretty much requires a degree in engineering to understand. There is nothing inbetween, no 'killer apps' that allow people to progress from the lego brick tools and work thier way up to the top end CAD software.

[@Irishrebel092]

what i want to see is a large battery pack like this, but mounted to your belt or backpack, with a umbilical cord type thing running to the tool. would take so much weight off the tool. just like an ego chainsaw

[@GeeCeeAte]

I used 3DSM for 20 years. I ALWAYS wanted to switch to blender, but with all my experience I couldn't ever make the jump. I used blender back around 2002 quite a bit. Well I got tired of Autodesks outrageous pricing. I switched to blender and its literally 100x better in every single way. Also within the first day I was pretty proficient, so it didn't take me as long to get comfortable with it as i thought it would. The only thing I like better in Max is the smoothing groups (which doesn't matter unless you're doing game design). Other than that blender 100% of the way. I switched to blender about 4 months ago. So far I've done 2 professional industrial designs in it. Its so much better. The measurements alone are worth it. I do still find myself using hotkeys from Max and it makes me wanna scream outloud haha. But mostly because I spent 20 years inside of an ancient software whenever I should have just stayed with blender all along.

[@bene3539]

Nice build, however triple strips on the series connection that barely take any amps and using a single strip for the parallels which take all the current is just a bit shady and will definitely lead to high temperature inside the pack as well as high losses due to heated up nickel ! Usually you reinforce the connection in the direction the current travels in this case between the series groups and not along them. Very nice project still 👌

That's correct! I made a follow-up video addressing this issue. Thanks for the useful feedback and glad you liked the project 😊

TIP for Measurements ... Scan some graph paper or 5mm sq lines paper and print it onto clear overhead projector film Place the clear film on the scanner bed and then the battery case on top It's easy to measure now

[@chris_hertford]

The temperature sensor is typically a 10k NTC thermistor, if you damage it or it needs to be replaced. It also does not matter which way round the thermistor is soldered to the board. When I used to work with Li-ion cells I used a large ceramic tile to protect the bench from inevitable burns! Speaking of burns remove all rings / watches etc! Metal jewellery can arc and the heat from a short circuit is almost instant! Get yourself some CA glue accelerator spray too.

[@davidbarker3591]

Don't forget that Milwaukee, SnapOn and another use a 6.8K thermsistor....

[@chris_hertford]

@@davidbarker3591 I see you're a battery connoisseur! I never had any luck with Milwaukee liion, 50/50 with the snap ons. Put it down to BMS locked when they fail

[@Doktoreq]

Great project but a bit safety precaution. PETG is not a great material for cell holder - it creeps when heated (you can use PET bottles as heat shrink tubing). It means your cell holder will start squeezing the cells quite hard which is not the greatest idea (fire risk and all that stuff). Using proper materials for the job would ensure project longevity and spare you nasty surprises down the line. If I needed more temperature resistance and only had a stock Ender 3 I would chose ABS/ASA for the job. If your printer have all metal hotend and can reach higher temperatures I would stick with Glass Fiber reinforced nylon (requires hardened nozzles). It's what bodies of most power tools and batteries are made of - it's reasonably stiff and impact resistant, has a great temperature stability and should be quite printable without enclosure (haven't tried to print it yet but heard it doesn't warp as much as normal nylon which I had moderate success printing in quite cold garage ~15 *C). Don't use Carbon Fiber reinforced filaments as them might end up electrically conductive due to Carbon Fiber strands in them.

[@grindel80]

very important information!!! i hope he will pin your comment.

[@White000Crow]

I’ve been thinking about doing this lately for my jobsite radio that runs off a Milwaukee battery. Since you used a BMS from a smaller battery pack, wouldn’t that limit your charge/discharge current to what the smaller battery pack was?

Great Video Your battery can definitely deliver more than 43 amps even the parkside 8ah does double of that. The only problem is if you try to pull this current the fuse in the PCB of the 2ah battery will blow

[@Solipsfilm]

Interesting.. Makes sense that the 2ah battery fuse wouldn't be designed to handle this amount of current, thanks for the tip, I'll definitely reinforce it! :) I did a short circuit test with the batteries, they deliver around 70A/cell, that's obviously not what they're made for but that would mean this battery could deliver 210A at it's absolute maximum 😆

[@Boz1211111]

2ah and 4ah batteries have the same fuse as far as i can see so to me it seems its the biggest fuse boards and contacts may handle. If it operates correctly with original fuse i would rather leave it as is

[@BICIeCOMPUTERconGabriele]

The amont of current he can pull doesn't depend on the battery, it depends on the load! If he uses it with the standard tools that are designed to be used with the standard batteries, there's no way he can pull a greater amount of current from it... This battery will last very very long without any decrease in performance. So it's ok to use with the standard PCB.

Yea i just bought the case and bm board on ebay for 15$… came with nickel strips and all.. used laptop batteries.. only tweak i had to do was research the protection chip they used on the board and desolder the supporting components on the leg that controlled the cutout amp draw limit because it was set too low for anything.

[@hyrochinz]

@@orppranator5230 You are right! but it only matters when the voltage difference is like 1 volt or more. Usually new batteries are within 0.5 volts of each other. So there is no surge current which is more than the c rating of the battery. Its more important in the series conections. What I do is. First measure all the voltages. If within 0.5 volts then i connect all of the batteries in parallell using small neodymium magnets and nickel plated strips. and leave them for like 24 hours. After that they are perfectly balanced and ready to assemble.

Dit is zonder twijfel een erg mooi project om van te leren en om je vaardigheden in de verf te zetten.

Dat lijkt mij alleszins het idee achter continuiteit in werken met batterij-gereedschap. Als je grote accu leeg is duurt het ook weer evenredig lang om hem weer te laden, dus toch voorkeur voor een opsplitsing van batterijcapaciteit.

[@crisnmaryfam7344]

Great project, but I have one advice. You have doubled the strips for parallel cells insted of serial connections. Actualy it doesn't make sense. Most of the current flows between serial cells (short horizontal stripes) - thoes should be thick. The long stripes connected directly to PCB can be actualy very thin, throu them flows almost no current 🙂

I know its rated for 12v (3s) but looking at the component and the cap.. i did not see any problem why 4S lipo (16v) should not be tolerated, and it makes a huge difference in the spotwelding potency. That small spotwelder was exactly what I needed when i purchased it some years back from BG at around 12USD, and also checked it with my oscilioscope.. its enegy rating from 1E to 99E is 1 to 1 with ms, on my scope and you can also use a footpedal with its small barrel DC connector if you need, but its "automatic" weld-feature works great.. and I love it doesnt take any space and can simply just grapp some of my RC lipo packs when I need to spotweld. for the price it was a steal.. but using 4S packs in parell made a big difference in spotwelding potency. versus fx 3s packs. Great build and impressive video from such a small channel (+1).. got many Parkside tools, X20 line , and also X12, .. and sadly also a lot of the Performance BL line (the old version with 2.5A and 5A batterypacks that carried Samsung 25R cells).. and which you cant get new batteries for, as the Performance line shifted to X20 battery-hinge variant. a tacky move from Parkside, dropping the ball on all the buyers that invested in their performance line.. IMO Parkside should at least make an adapter, so they can use X20 packs and buyers not ending up with quality brushless tools you cant get batteries for. dang, that x20 gluegun just look dwarfed alongside that pack. Im using 4A X20 with the same gluegun.. and its not a bad gluegun with its price in mind.. can deliver quite a bit of hot glue in a shortwhile and ideal for certain stuff. Are you sure that 2A entry batterymanagement system are not choking that huge pack after the original 2A X20 pack current-standards.. just as when your charging it will be the slow charging speeds. wondering if you actually gonna feel the effect of that huge pack.. like one useally do when using bigger batterypacks and not just longer runtime.. going from 2A to 4A pack big difference in torque on most of my powertools.. same on the older brushless with 2.5A vs 5A..angle grinder would way easier stall on low sized packs..

Hey Hey, great video, but i have some questions: 1st i have some 16850 cells from old laptops here, is the case still usable with them? i always see peps use nickel and weld them, but yesterday i say someone using coppertape insted, do you know how good/bad it is compaired?

[@OMARENGG22]

[@soisun2658]

Impressive beautiful work. Congrats!

[@ChapuzasconRober]

Awesome job!

[@Solipsfilm]

Thank you!

You should have put a 1.5m cord to power the tool from the battery on the floor. Still portable but wired to be light weight holded

[@olfausto1018]

fantastic. prepare me 2 batteries I'll buy them for you.

[@Solipsfilm]

I'm sorry but I dont have the time to make more at the moment.. But maybe I can help you out with the printed parts? www.etsy.com/nl/listing/1211082739/3d-printed-15ah-parkside-battery-as-seen?ref=listings_manager_grid

[@ericklein5097]

@@Solipsfilm the amount of entitlement in here is ridiculous. They probably think you would sell them for $100 too!

[@MrQuidy]

Do this for Milwaukee M18 packs and I will personally donate you the price of their M18 battery pack :D I would love to buy an old used Milwaukee M18 2ah pack and extend it to 12ah instead of buying a new M18 12ah for freaking 250 European schillings... Their tools are amazing but the price of batteries is just ridiculous. Anyway, you have earned my sub :)

Angle Grinder.... The Real Man's Dremel.... Noice!

[@Solipsfilm]

Hahaha, indeed! 😆

Is the phone connecting to octoprint or is the phone running Octo4a?

[@xgamer]

Very cool project.

[@Solipsfilm]

Thanks!

[@mocriders820]

nice battery pack good work. But I wouldn't want to work with it all day, it must be too heavy.

[@zakariyasajid7378]

i flinched when you used the callipers on the cells until i realised it was plastic lol

[@PlayerLeonardo]

Such a great project!

[@GerusalemmeCristiana]

Bravo bravo bravo

[@Solipsfilm]

Thanks!^^

[@jeq2822]

Sweet, nicely done! Well explained!!!

[@jesse8333]

hey I'd love to see a video using Solar panels and these drill chargers as a quick Jerry rig system

[@okhascorpio]

1:50 Gave me a scare but then realized it's a plastic caliper. Most people have metal ones and will be in for a surprise measuring their cells like that. 💥

[@Solipsfilm]

Haha, plastic indeed 😆 I have a good metal one by now so I'll also have to be careful doing this in the future
