Yup, soldering damages cells and shortens the life of the battery. You can solder but it damages the cell and shortens the life. I would rather do things the right way and end up with a reliable battery that will last and that I can trust
Not everyone can spot weld, lot of us are not capable to make spot weld or even buy it. Some of us are not even technicians and repairing is just part of our hobby
When they are dismantled from there packs dont remove the strip. Cut it and fold it into the centre and solder to that. My whole 5000cell Powerbank is made this way.
I had the exact same issue it’s just your technique. Clean the soldering iron then simply wrap solder wire around the tip of the iron and wait for it to melt. Not you’ve tinned your iron after that just put solder on it and get to work!✅
add flux (use HCL - hydrocloric acid) get hotter soldering iron, 80-100-150 watt, the higher the hotter the better, faster melting time mean quicker soldering, better for the battery
@@toxicity6629 passez simplement un coup de papier de verre sur vos batteries et surtout avoir la panne de votre fer à souder propre et vous n'aurez pas besoin de flux, vos soudures seront très facile à faire
Okay. Absolutely do not solder to lithium batteries. That damages them 100% of the time and can cause a fire. You HAVE to spot weld nickel strips to lithium cells and then you can solder onto the nickel, but NEVER solder onto lithium cells. They are not designed to handle any temperatures too far above body temperature.
NEVER solder directly on a Li-ion battery. Damage guarantueed. Spow Welding is a MUST. They're cheap on ali now and you can use a car battery. that's all you need really. If you want a fancy spotwelder that's even better of course, with safeties and such.
need to be careful, I once accidentally dropped one small soldering remain/ball into the slot on the postive side of battery and caused short, battery became very hot.
@josepeixoto3384 I belong to a group that make nightvision cameras and a few has stupidly busted the battery. Decent protection to be worn including eyes.
Идея отличная (чот я сам не додумался) только одно НО! - флюс смывать надо! Иначе разъест металл и проводника и батареи! Сам об это обжигался в начале. Смывать с аккумов надо спиртом и ещё "капать" на "плюс" надо буквально смочив зубочистку. Что бы он не затёк куда не надо.
TQ. Great idea. No, the heat won't damage the battery due to the short durations required to solder (pre-tin). More ic's components gets destroyed from soldering heat. No, the soldering solution is not corrosive vs standard soldering paste because it is a new type of wet solution base that evaporates with no corrosive residue (like alcohol eveporation with no residue left-over). Available from Amazon, Lazada, any online shopping... search soldering paste.
@@R.B_B it's right I front of me right now. No smell, like water, leaves zero stain on the stainless steel plate after leaving it to dry, no smoke,no fume, no smell when applying the hot solder on it... and it is super great; apply and wet the area to be apply with hot solder with just a tiny bit and the solder simply flow and spread flat and becomes part of the metal/copper, etc. Using the best German made expensive flux to solder was only half as good.
I have been soldering circuits boards, soldering lots of DIY stuffs and in the business of electronics for 50 years (retired now but still passionate about all things DIY and still soldering all kinds of stuffs)... whatever this clear, colourless liquid with no smell, no fumes is the best thing I have come across...just apply a little on any reasonable clean surface and solder flow, stick and spread the metal surface; superduper.

@@dariuszhebda3062Over the years, soldering on stainless steel, steel, or any metal strips, plates is a real pain in the neck. You can scrub them, sandpaper them clean, wipe with alcohol, apply flux/paste (except for expensive high quality German's made flux/paste)... getting any types/brand of solder to spread/flow smoothly on stainless steal surface of strips, plates is very difficult and the solder are clustered and lumpy on the material surface... after using/applying this made in china: "unknow colourless, no smell, no fume, liquid, no stains, no residues on the soldered surface" ... it was amazing the hotbsolder instantly and smoothly flow FLAT on the surface of the 18650 Li-ion Battery Nickel Sheet Plate and nickel-plated steel belt strip... super.
Put your finger directly on a spot weld as soon as you've done it and tell me how cool it feels. Your comment already tells me you've never spot welded anything before.
En Aliexpress lo venden como líquido para soldar baterias de acero inoxidable 18650, pero a mi desde Uruguay no me dejan traer ni pegamento siquiera porque dicen que es pegamento peligroso para el avión. Dicen que es muy bueno puedes soldarlo mucho más rápido sin calentar tanto la batería.
Interesting and should work with other battery types. At least there seems to be a protection circuit on top of those batteries. I wouldn't do that with raw 18650's

Dude, it doesn't matter what the material is, because it's only used to make the nickel strip stick to the battery. The heat will still destroy the battery.
@@Abilex53 You literally cannot solder a lithium battery without damaging it. If you think you can you don't understand how batteries or soldering works. They are ONLY supposed to be spot welded. You CANNOT safely attach anything to them by soldering.
