@@omairkhalidmirza you shouldn't due to the fact that the cells are different age, even if they are identical rated capacity, they will have different resistances and they won't charge or discharge the same, it's possible but not the safest, i wouldn't recommend

Unfortunately a battery is the cheapest option without a DC power supply capable of such Pulse currents.

@@BattTube What about putting big capacitors across a DC PSU to allow a large pulse current ?

Yes obviously 🙄

There is no over-current protection, Your probably using a battery outputting to much current. The mosfets are just switching a short circuit in pulses. I have had no problems. Its also a possibility you got a bad unit?

Car batteries don't handle pulse current as well but yes, one with suitable amp output. I have a tote full of lipo that i am afraid to even budge, unsafe really, don't be like me 😅

Im a contractor so im pretty familiar with all the brands, Mainly operate dewalt at work but every brand has atleast 1 tool thats better than the other brands, Would just suck to have to carry more than one brand of batteries. All the new brushless tools are junk though, I wish they would bring back brushed tools, I've never once changed a single brush and they don't have motor controllers that fail and suck at speed moderation. I've seen 3 brushless drills/impact fail within 3 years, One of which was faulty out of the box. The only brushed tool i ever broke was because i was pissed and threw it across the job 😅. I kinda ranted there but all the tool brands suck somehow lol

Im sure that would work just fine!

These were recycled LiPo. Your not wrong though, that's exactly where mine is right now lol

You can get a LiPo battery with the required C rating for like, less than 50$. A car battery is like minimum 100$ at least here in Canada

​@@amogusenjoyereven cheaper, ever see those Shrimp cells batteryhookup has? There even cheaper but depending on where in Canada you are the shipping can be a killer. Cheers from Peace River

Lead acid battery is the worst battery, you can choose for a spotwelder. 99% of L.A bat. are too slow to build up the needed amperage. The correct lithium cells are the absolute best choice.

I've tried a sealed lead acid battery there no way as good as model air craft battery. I used a 5500ma battery the welds are perfect. Good video

The video has chapters for this purpose.

Both statements are interchangeable, for the purpose of this video it felt more appropriate to say it that way as that was the unit we had to consider. As for those other notes, that's well beyond the scope of this video and there are many other better KZbin videos out there to explain all that. That's a whole debate in itself currently.

@@BattTube NO = they ARE NOT INTERCHANGEABLE What gave you that idea ? Because you heard other poorly educated =- illiterate people say. The words have different meanings that are simply beyond your level of comprehension. Your knowledge in this regard and knowledge of the English language is poor. Undertake an extensive reading program to better educate yourself. And had you been in my classroom - even with my youngest students age 8 - THEY would be able to teach you. Without giving you a detailed history of my background - you will not understand - and I have no need to justify this to you - It is not a job application. However - understand one important lesson - If you are not teachable - you will remain ignorant and proud of it until you die and learn very little in your life. Good luck and Good bye Example = Speed and Miles per hour are not the same thin Miles per hour is a measurement of speed = as Amps is a measurement of current. Make sure you get that into your head.

@andrew The use of "amp" here in describing current is short for the word "amperage", not the SI unit "Ampere" (abbreviated as "Amp"). The ambiguity is resolved by context any listener performs virtually subconsciously. You are being too literal. As to the remainder of your comment, Mr. BattTube is busy washing the asbestos dust off his hands after realizing the white powder spilling out of the battery packs he disassembles without wearing nalgene gloves may, in fact, not be drywall dust at all. I will take the liberty of completing your homework assignment for him. (My heritage is Canadian, it's the least I can do for him. And Canadians are well known as "nice people." It's just the nice thing to do.) Part 1: Voltage is a measure of electrical potential. Electric potential is created by the separation of positive & negative charges. It is manifest as an electric field throughout space defined by the geometry of the charge separation & Coulomb's Law. A test charge within an electric field (conventionally noted as a small positive charge, +𝘲ₒ) will feel a force acting on it from the field. Just as moving a mass against the force acting on it in a gravitational field adds gravitational potential energy to the mass, moving the test charge against the electrical force acting on it adds to the electric potential of the charge. Gravitational & Electrical fields are conservative fields, meaning the difference in potential between two points within the field is not dependent upon the path taken between the two. Voltage is a measure of the difference in electric potential between two points in space, to include two points within an electrical circuit. Part 2: A property that makes metals conductive is that the electrons in a metal are loosely bound to the molecules & atoms that constitute the metallic structure. They can become unbound as "free electrons" by the smallest of forces to include the application of an external electric field. As a result, the movement of electrons will occur throughout an entire length of any wire constructed of metal. As unbound electrons, they also manifest their own point source, radially symmetric electric field that all the other free electrons will feel. Because they are all like charges, this mutual interaction will be repulsive so that all the electrons will want to be as far away from each other as possible in a minimum energy configuration. Thus, the free electrons will reside on the surface of the conductor, being held from escaping beyond by the positively ionized metal atoms of the wire. Like the surface of a soap bubble, the electrons will arrange into a minimum energy geometry. A Point of Order: Your terminology also has an issue. Technically, the phrase "electricity flow" is more ambiguous than even "amp" since the context isn't necessarily as distinguishable. There are two things going on here that the term "electricity flow" may refer to. There is the movement of the free electrons in a conductor, and the transmission of power around a circuit. They are coupled, yet distinct, phenomena. The electron movement, or current, POV for your terminology I have already described above. The other interpretation describes power transmission and involves an understanding that the energy of the current in a conductor resides in the electromagnetic field produced by the current & is completely outside the conductor. To demonstrate your understanding of this aspect of electricity flow, your homework is to reply with an explanation of the Pointing Vector. *If there are any inaccuracies in my explanations, please call them out for me to fix so that I'm not spreading disinformation.

Are you able to re-write your text and format such text into logical paragraphs - and not write what is an almost endless line of text. Do CANADIAN schools teach writing and literacy skills ? Per-haps were you asleep in class and not paying attention. In addition the word NICE is a negative word as are many words beginning with the letter N - and this applies to other languages. The word you should have used is PLEASANT - Do remember to use it in the future - choose your words carefully. I will await your reply to be re-writen and formatted so I can read it comfortably without suffering a Kopfschmerzen. Study how text is formatted in books - Newspapers and Magazines. Study the Chicago Style Manual for additional information. I am familiar with the ' Chicago Style Manual ' having written and collaborated to write eight procedures manuals for the USAF and RAAF prior to that - and much later - two manuals for a Multi-National Petro-Chemical CORPORATION ( Total page count 2700 pages) (1500 + 1200 respectively) The purpose of which was for the CORPORATE entity to obtain ISO 9000 and ISO 9001 certification -- Thus one had to be familiar with the CHICAGO STYLE MANUAL. There are rules and protocols for writing such DOCUMENTATION and Legal Documents. Legal documents MUST use correct grammatical legal English - not the peasant level English taught to the common people at the CORPORATE GOVERNMENT indoctrination center - known as school. Besides serving as an AIR FORCE PILOT since 1961 - beginning with the RAF (Bomber command to be specific) In the 30 years serving three countries - I studied Law - Electronics and - Electronics & Elctro-Mechanical Engineering - specializing in Robotics - Also hold a Masters degree Psychology and national security studies and Risk management. Following retirement from the Military I taught Law at Night College as well as English and History In High School - The most rewarding was working as a relief teacher and teaching students age 7 to 10 -- They are logical thinkers and their mind is not contaminated with negative social expectations that are considered appropriate by society. These pressure groups aim to increases social acceptance buy that group. In simple terms - classical conditioning - it is social brainwashing and indoctrination to ensure the people fit into the common belief structure of society and to avoid becoming independent logical thinkers. Even parents teach their Sons and Daughters by repeating 'Don't be smart' in the end the child (legal terminology) accepts that being 'smart' is not such a good idea.

@@andrew_koala2974 Lol, okay.

It goes against common sense but more resistance will melt the nickel. Think of bad connections in homes that start fires. Its resistance heating stuff up. So its a matter of finding a sweet spot between getting enough current but also getting enough heat. Thats why you don't press down super hard with your electrodes, just light pressure and you angle them slightly so you are using the sides and don't have super pointy tips (reduces the contact area)

​@@ericklein5097Common sense also says you can sound louder if you boldface your capital letters.

Bought them from a battery recycling plant, Can't do that anymore because regulations are getting really tight

A place called the internet can help to find those batteries as well! 🤯

@@mxb2432 Ah, you say they're all the same and I can rust what the vendors claim? Jeez, if only I'd have known.

The cells were tested ahead of time. I discharge and charge any recycled cells i get and mark the capacity if it is over like 2-300mah different from specification. I do resistance test each cell but as long as they are the same model or chemistry then typically the capacity and resistance are closely related.

Nah it's too loud lol, i use it as my volume 🙃

@@BattTube owh... oke oke... 😁😁😁

I live in urban Baltimore. The less noise the better. You wouldn't want the buzzer to drown out the sound of nearby gunfire.

Your thinking of capacitors
