Everytime I saw video like this, I go to the comments and look for someone who arguing about "don't solder on lithium ion battery". There are always people say the same thing..
Well, you are quite right (for someone who really have enough budget to buy spot welder devices), but also you are not really right. You can solder on battery if you know what are you doing. The correct advice is "Don't solder too long on the battery until you overheating it". That's why you have to learn some soldering techniques to let you avoid soldering on the battery too long. You can even solder as long as the spot welder weld metal on the battery terminal if you learnt the right technique and use right flux and material. I did this many times already. I have a solar power bank using soldered connection batteries, it still works from 2020 until now. Only downside of soldering is, the connection not really neat compared to beautiful spot welded connection.
the guy in the video is using the Wrong Tip. and the wrong solder too.
the best Tip is to use the D tip. (Flat)
and fold the solder so you are melting twice as much in one go.
twice as much means cutting solder time to half.
Everytime someone says 'you can do this if you know what youre doing' , proves they dont know what they are doing. They just dont want to look stupid. I get people who say this during snowy weather and people drive fast, like idiots, as if its magic words that magically gives their tires super sticky qualities that make them stick to ice so they dont lose traction and crash.
Easiest way to do this. Use a Dremel sander to clean the battery. Apply a smear of plumbers tinning flux, then touch with a very hot iron and 63/37 tin lead solder. Do it hot and fast.❤
thanks for tip :)
Do it hot and fast? Thinking of sex too, are you? Thats the way i like doing it, hot....and fast.
This is just fine. You may slightly damage the internal structure.
But what I say... is that by removing that outer-coating that the solder won't adhere to, will rust. Guaranteed.
So.. it is a Bad idea?
Good point.what grease would you use to prevent that?
@@quickdrawmcgraw4394 You can try using DeoxIT D or G series to help clean and protect contacts. It also helps prevent corrosion. It is great for water and contaminant displacement. DeoxIT is great for cleaning and prevention. Zinc-it is great for the prevention of rust.
@@JoeRodge thank you for that information
Do NOT solder on li-ion batteries!
why? how do you suggest attach wires to them? A welder is not an option for DIY.
@@TechscrewHome inside the battery, there is a plastic bit. If it melts, it doesn’t just kill the battery. It lets oxygen in, causing an extreme fire. Besides welding, there are many other ways to connect. Magnets, clips, etc.
@@hjeffwallace Therefore need use solder a quick time.
You can solder in less than 3seconds
@@TechscrewHomeI think he is telling that to the rookies who might accidentally make a shoepid mistake
SOLDERING ON BATTERYS IS DANGEROUS use an sot welder and nicle strips .
If u heat the battery to much it can explode .
max 3 seconds and nothing will happen
@themastereal8345 yes it will even if u can't see it it will reduce the capacity of the battery
@@Dominik_Lnkare you sure, have you actually tested a soldered battery compared to spot welded, those strips are very bad current carriers compared to copper wire so that's the dilemma?
@martinmuldoon603 you are theoretically right but the energy loss is so minimal that u won't notice it . With my battery pack 9s 5p with an max current of 20A . The stripes don't get hot etc. But soldering to battery's is as mentioned above realy bad and dangerous
@@Dominik_Lnk thanks for your reply, I must do some tests to see for myself, I am aware that main manufacturers all use door welding with nickel strips, I've read are actually very poor conducters, without actually testing the average person is only guessing. I agree in the first instance soldering has drawbacks and high risks, could even melt under high load.
Even if the battery doesnt blow up in your face you can greatly reduce the capacity
If you cant afford a welder, you shouldnt be buying these cells. Just pay the store so someone who knows how to do the job right canconnect or put tabs on your cells Welders are cheap asf these days to do it right. Ive soldered on ni cds before i got one and yhey usually didnt work afterwords. What happens when you try connecting these? You gotta heat them yet again to connect the wires. They of course wont fit in a battery holder anymore
Dude buy a D tip (flat head)
and fold your solder so you can melt twice as much in one go.
these 2 tips will help you cut your soldering time to half.
Hi Can you supply 12v 15A battery?
Please don't do this. It's fine to solder that strips on pouches if you can't weld, but cell type batteries have to be welded or nuted.
you suggest for DIY project buy welder ?
@@TechscrewHome yes, some cheap super caps, a balance board a switch and some thicker wire.
@@eivis13 sounds good, do you have link to project ?
search youtube, idk if i made that choice by watching some hindu dude weld with 12v truck batteries or i found it somewhere.
@@TechscrewHomeI know soldering them is possible. I have done it, however, I'd recommend buying a cheap spot welder. I have a Kweld and I love it (150 bucks) but the kerpu spot welder (50 bucks) is cheaper. It is way less powerful, notice max thickness. It's not a problem at all to solder to those strips once you welded them on
Thế này mới là thực te..❤
Use special flux and a flat tip
Whatever i do, the solder never hold on the battery surface, i tried scratch it, and also use of detergent acid on it,, but the solder never hold. It always break.
satisfuing
Wattage of soldering iron 🙄
around 35w
@@TechscrewHome 50w work krega 🙂
soldering paste laughing at corner 😂😂😂
Use battery holders much better and safe
maybe you can recommend some? Thanks
It's dangerous to expose the battery at a high temperature even if it's for some seconds..
So dangerous. And those solder joints are colder than a barefoot trail runner on Hoth.
Друг, ты слишком долго греешь, они этого не любят!
Lityum piller lehim yapıldığında bozuluyor tehlikeli...
please eng :)
Да!
passer sur papier de verre 500 après la trempé dans l eau froide et soudé les connexions !! Voilà voilà
please eng :)
No es recomendable eso por qué puede esplotar las pilas es mejor soldadura por puntos😅
please eng :)
The fact you soldered successfully with a conical tip (which has less surface area compared to others) amazes me.
What temperature did you apply? Because I’m having a very hard time doing this even with the highest temperature 450.
Just use the side of the tip
In the video he also used the side

This is EXACTLY how to NOT solder. The solder should go between the soldering iron tip and the place but you drop some solder on the soldering iron tip for ? It CAN make a cold joint. But basically you REALLY must learn how to solder AND how to keep clean that poor soldering iron tip .
- first, the soldering iron tip is clean, if it wasn't clean, tin wouldn't stick to it
- second, to make a quality connection, you need to heat the surface you are soldering. In the case of soldering batteries, this must also be done quickly to avoid damaging the battery.
@@TechscrewHomeYou aren't going to be talked it off this, I think you demonstrated that you can do it but not everyone is as good at soldering and that is where the problems start, so still not to be recommend to average person as it is dangerous, I have soldered batteries many times myself but I'm not sure if the battery was damaged internally or not. Professionals don't use solder so ask yourself why and that's why I'm researching this very topic and I came across your video. I'm planning on soldering with copper wire to reduce current flow losses at high currents, for normal low drain uses the nickel strips are fine
Don't solder on li-ion battery, no danger sense?
in life, you have to take risks to get success
Oh this is gonna trigger people lol
The problem is my soldering machine is not working😭
sad :(
the video should be called "how not to solder 18650 cells 🤦"
Toooooo amateur even for a DIY project, apart from the controversial fact whether you can solder cells or not...
Because contrary to what many people think, YES 18650 cells can be solder!!! 😊
The only question is whether the author of the video has ever heard of soldering acid, because I don't think so 🤷
Skillful soldering of cells takes about 1 second and is not harmful to the cells.
Unfortunately, this video only shows how you should not solder cells 😅
it's also good to know how not solder cells lol
And you provide 0 re-course. Great job. Amazing 😂
Wer an Akkus rum lötet hat nicht mehr alle auf dem Christbaum. So blöd ist fast niemand!
eng please :)
Anyone who solders around on batteries no longer has them all on the Christmas tree. Almost no one is that stupid!@@TechscrewHome
Good work
NEVER SOLDER BATTERIES
why not ?
There is a liquid which helps you to solder on steel batteries.
what kind of liquid, name ?
?
Shop online. You need special liquid to solder stainless steel base if not the solder will turn into a ball and will not stick.
@@boblim5530 what’s the name of it
@@TechscrewHomeflux
I had one blow up on me. DONT DO THIS
thanks for feedback :)
All I needed to see. Spot Welder it is, this repair can wait til Wednesday 😂
Hell no
Loool very dangerous 😅😅😅
true :)
таких идиотов,кто паяет игрушечным паяльником аккумы,сразу пролистываю,паять их надо 100 ватным,быстро и в одно касание.
as you can see the connection is made very quickly, 100w is required when soldering thick metals.
How to solder lithium batteries?…DONT!
You are an content creator, please at least do a research before make something like these, and put a WARNING before the video is start
it's way how to solder on budget 18650 batterries for DIY projects.
Don’t do this please its very dangerous
i am pro :)
@@TechscrewHomeThe people watching you AREN'T. They don't use solder in manufacturing.
Wrong method
why wrong ?
It is how don't solder batteries. Who watch this video please don't it, first you will damage the battery, second can explote in your face, 3 after burn you the face burn your house too. Don't follow this prank.
Reported
thanks for feedback, but just do it quick and it's done. You cant bought special welder for some DIY projects.
@@TechscrewHomeYou can make a welder or but a cheap one. I think if you are very skilled at soldering like yourself quick on off you will be ok, however if solder doesn't stick first time and user keeps heating then it will definitely damage battery inside plus if you heat even longer the battery will brust so therefore not recommend for safety reason's to the general public.
just use spot welder or use 18650 holder😅 hospital is more expensive hehe
true :)
I don't care how good you are this is a real bad idea
it's not bad idea, if you do it quickly.
not bad idea . 100 billion people do this same
very very dangerous, if overheated-explosion.
then it's simple, dont overheat
