Another great project Sorin, honestly its video's like yours that give me enthusiasm to build thing and bring idea's to life.
Keep up the great work !
On a more serious note, this is a really good build. Very informative. Very helpful. Thank you for taking the time to produce this CZcams.
Sorin, you are the man of the DIY. Thanks for these good works.
Superb Video. Very clear, step-by-step build, with concise explanations, which include dry humor and feline assistance. Thank you, Sorin.
This is a great build. Very simple and super useful.
I have been thinking of getting one of the prebuilt portable ones for my channel. However this looks great too. I might try your approach and make a video for it.
Excellent video for instruction, very professional and awesome audio explanation with clear video. Many should follow your style. Your assistant is also to be commended.
Very interesting and useful video. Specially thanks for attention to great details, that made me confident to assemble similar DIY kit. Which already bought components but not yet tested.
Great video Sorin, with that size box you could use a small solenoid between the spot weld PCB and leads which could break the circuit at the same time as the 2 x H7 bulbs you used.
Thank you for sharing your eyeball engineering, great job.
Know that the Light of your being is a blessing to everyone on your journey.
Shine on
You covered lot of things in single video ❤️❤️❤️ thank you. 😁 Feeling happy after watching this video.
Nice conversion kit.As always from you Sorin nice tutorial
Excelent project! I'm very impressed. Thanks for sharing!
I do like the way you finish/house your projects especially this time giving everything a bit more space. Do let us know how the battery performs over time.

I love the concept of "I can use *all* my devices as independently rechargeable power sources".
This is nice AND security oriented. Well done and quite neat!
Greetings from Canada. Loved your video and appreciate your sense of humour, all the best to you.
Foarte tare proiectul! Felicitari, Sorine! Am dat intimplator peste clip-ul asta dar ... abia astept sa vad ce alte proiecte ai mai realizat. Succes!
Sorin! I Just Subbed. You have all the right "ingredients". Delivery, Clarity, Knowledge, Information about sources Listed. A+
High quality videos. Thanks !
It's channels like this that make CZcams great. Thanks Sorin! Liked and subscribed.
I like it, it is perfect for DIY battery packs (and don't need the use of pedal switch) thanks for the video .
Always an inspiration man! Keep up the good work!
How come this is the first time I come across this channel?! You rock man!
Very good video, good explanation, perfectly understandable. Thank for sharing. Good work
Very excellent video. Love your sense of humor !
really great work..thank you for the knowledge.greeting from Indonesia💝🇮🇩🇮🇩🇮🇩
I love the level of comedy you always put in your videos.
Yeah... Sorin Uploaded a new video 🥳🥳
I love your cristal clear explanationa! Good video!
Brilliant content!
It's most likely that the amp rating on wires is continuous discharge and will be able discharge 2-3 times for 5-10 secs even 4 times if sub 1 second discharge
Hey, I just found your channel and I have to say that your content is A+ quality. It was interesting and informative! Great video Sorin! Also I subscribed to see your future projects on time!
Arată bine . Foarte util pentru cei care fac pachete de battery . Uite o sugestie ai putea să folosești 2 brekere de aperaj mare sau mai multe in serie pe post de întrerupător aşa ți-ar fi mult mai uşor să deconectezi bateria. Plus niște terminale pentru filere de la modulul de sudură . Xt90 pentru ale separa de modul .
I love your videos! From South Africa🇿🇦🇿🇦🇿🇦
Even though I have no need for a spot welder, this video was very enjoyable.
Thank you Sorin. Superb. Don't change a thing style wise. It's all great, clear, logical and funny. Carry on please... xxx ;-)
Ce tare esti omule am respekt tare, sanatate si toate cele bune sorine😉✌️
Excelente trabajo! Claro e instructivo! Gracias!
Hi friend, Nice video. Just i saw this. Clear demo and explained. Super.
A very good project and helpful 😀video construction, Sorin! I will make one spot welder like yours in the next times to solder LiPo 18650 packs for my rc submarines. Have a very good New Year 2022 and regards from Spain!
Thank you for the very informative tutorial video.
i love electronics. like your presentation,, you are an ideal person for me to watch these sort of videos. good luch for the future project.
Nice job Sorin 👍👏
bravo sorin asteptam si alte materiale
Awesome. You are the best diy channel. I love your speaker videos. It will be nice if u can make a powerful 5.1 hometheatre system.
You present your videos with super quality, I admire your talent. Oh, and I love the way you include your cat.
that's a very cool spot welder Sorin!. : ) well worth the few quid you spent o it.. i think i'll make one for myself, lord knows i need one. : ) THANK YOU FOR THE VIDEO, IT WAS CLASS!!
Thanks my favourite chap from Romania!
Very nice sorrin ! Again u made a great video !
I like your sense of humor!
Great video, Sorin!
Well done. Great video
another great video, mate!
Little to no explosions is always a good thing. Good job!
Very nice project 👍
Very very nice I really like your project very much :)
Very good video Thanks!!!!
Thank you for this video I purchased one of these spot welder is exactly the same as yours and I was impressed with the performance I haven’t really got any battery packs yet with it but see what you have done is give me some ideas and has given me a lot more confidence to go out in a full build of the spot welder project I use a disabled scooter battery for my spot welder but think I might invest in a lithium polymer batteries for the billed Thanks again for all the projects and good ideas that you put out on this channel I really look forward to the next one on the big hi from the UK stay safe
Car battery New or good only
@@bobravenscraft5376 Yes I think you are right I’ve been using a very large lead acid battery and it works fine I’ve now finished my disabled scooter battery just bought an active balance board so I can keep it in balance even though it’s got A BMS all the batteries are different mics I’m slightly out of balance
Top class DIY video.
Good demo and advice on charging levels for lithium-ion batteries as well as the intro to types I wasn't aware of until now. Btw, like your cute little inspector checking things out 4u.
Sorin, just subscribed 👍 Your english is amazing.
Merci j'aime beaucoup ce projet !
Good video! Enjoy the humor.
Another great project Sorin. Looking forward for more projects in the future.
Bravo maestre !
Very COoL & a Good Job. Thanks! Cheers from So.CA, USA, 3rd House On the Right.
Great video
I think they left those two components for the user to solder because they are trough hole components that can't be soldered automatically, and thus are more expensive to ship all assembled.
yes, that makes more sense :)
They do it to avoid damage. These passives are relatively heavy and the packaging usually sucks. Vibration or rough handling during transport can damage the components or solder joints. Their safest bet to avoid complaints is shipping these parts separately.
Very good 👍 my friend 👍😊
good job. i need it.
La multi ani pentru 2022 si felicitari pentru toate prezentarile din video-urile tale. Mereu este o placere sa-ti urmaresc realizarile.
great video
I just became your subscriber because of your explanation
Great video and like the way you comment and speak. Special thanks to you adviser ( the cat)😊
Great video, Funny also
Even though it’s simple
it’s still a good project
hello sorin......i am your great fan and all rest of your design of other projects were awsome....you could have made a custom case for this projects....please make a custom case for that...i cant see such a master piece in that king of a plastic box
Simply the best, Melcule :)
merci si la multi ani in avans pentru maine! :)
@@Sorin_DIY, thank you!
the 90-120 amps required by the spot welder is for micro seconds so its okay the given components can handel this job but if you are building very big battery bank then you might need to take a little break to cool down the cables. for 11$ it is good looking
Nice job.
Nice Project. the only mods i would make are a set of heatsinks on the mosfets and a fan to keep them cool thus extending their life and a cut off switch on the lid so it cuts power if opened thus to prevent any small conductive materials from falling in when open and being missed the one device you dont want to let out the magic smoke. ... or a shock yourself when disconecting the battery pack
The mosfets don't seem to have any driver circuits, so they will spend a lot of time in half-open/half-closed state and high-resistance.
Nice video, keep it up, thank you :)
It is awesome
你的方案非常好。感谢你啦
A colleague of mine has a similar kit which he uses quite often for spot welding DIY battery packs. He's now thinking about making a spot welder from a microwave transformer because he might change the battery as its performance dropped significantly within two years.
Maybe you could sometime make a spot welder from a microwave transformer?
Maybe he should just buy another battery. That's not too expensive considering it lasted for 2 years. They don't last forever. I regularly change out the batteries for my miniquads, and thats like 15, 4S batteries.
@@minkorrh That's the point. He doesn't want to buy a new battery every two years. If you have a transformer operated spot welder, it will basically last forever, if constructed well.
good project great
With high currents i usually ensure only good contact but i never solder because it will increase contact resistance (is solder makes its way between copper parts ) producing more heat
I just ordered stuff. Of course it will take 2 months for everything to arrive :)
I used your affiliate links so I hope you get something from it. You did a good job explaining how to assemble, so I think I should be able to do it as well. It cost me 65,07€ all together. Cheers
I just did it! Based on your instructions! Thanks man for clarifying everything just enough so it was possible to repeat all the steps. I did not do it completely the same as my box was too big, so I just used a back plastic plate for it. In the next couple of days I will try to spot weld my first battery pack. Now, only the sky is the limit :D Cheers!
Very nice
Keep it on, Sorin. Your videos are amazing!
Your design is very interesting and help me to making my projet
Hi I wait a lot for your videos
That spot welder kit you bought is garbage i bought 2 of them and the both blew up before i could build a 10s 10p battery the mosfet on each board let put the magic pixie smoke
Thank you for giving more screen time to the DIY superstar Kitty this time..
Nice. They used a machine to install all the SMT parts and reflow soldered the board in an oven, the through-hole parts have to be manually installed for more time and money, and it’s much easier to do, just time consuming, so they leave it to the user.
yes, that makes more sense :)
Hi Sorin,
I really like your DIY videos as you also explain the concept also, I look forward for more amazing projects.
I was building the same spot welder and I have almost everything now but my lipo battery is 4200mAh 3S 35C so can I use the same or I need to purchase battery with higher discharge rate to make this spot welder work properly.
Thanks
I suggest you buy a battery with a minimum discharge rate of 60C.
I sure do like this guy.
Subbed you so that you reach 1 lack best of luck pal.
Great This projet
Great!!!
you gotta love his elec. assistant
For using your cat in the box build you should have tried cyan glue. That hue usually sets before the cat can walk away.
