probably that charging IC will burn to ashes until you fully charge those batteries, even there is a possibility that many batteries will explode because the voltage and ohm ampere values in those batteries will not match each other, but sometimes if there is their own special bms inside the batteries, the battery will cut off the charge by itself without exploding, at most those 3 sister batteries. it will be good for you to use the mountain, let's be careful

Hello Electronic help care! I love your videos! You should be a role model for all western countries! Do not always dispose of everything, repair it! There is a small group of people here in Germany who work like you. It's called a "repair cafe". Old devices will be repaired again! I think that's great and so do many other people who come to us. I am also an active member of the "repair cafe" and have already copied some of your great tricks! Thank you for all the videos, keep up the good work and be our role model! Many greetings from Germany! Patrik

Add saltwater to that sand and watch that battery coming back to life 😂😂
Great video, I'd just like to say that its a good idea to charge and check the voltages in each battery and only pair similar voltages together, the closer to 4.2v the better. I just built a battery pack with 6 18650's and each battery was between 4.10 and 4.15v, the charging board in the video is the same one that I'll get in the mail today and I'm going to wire them together tonight.
Yeah

Boa tarde, essas placas pode aumentar o números de células sem problema? Deve ter um limite ou não? Tipo essa dai pode colocar 12 células? Obrigado amigo.
So, what is the time period between charges....... a few hours or days of power before you have to charge it again?
Great video, good music and amusing as you just casually went over the sand batteries like its normal within the current market :D
Just got to add to all the comments about the sand All that sand 🤩. No grate vid really came in handy for the rc cars 👍
That's a very dangerous work, cause you need a special bms circuit for that quantity of batteries (if you dont' have the good one, batteries can get overcharge and explode) also you need to recharge one by one of the batteries to have the same voltage and don't damage the others batteries when are all connected, and that wire solded between the 2 package of batteries must be selected according with the maximum current of the circuit.
Luis R finally , i was searching through the comments because this video did not mention anything about wire gauges or battery configuration ... someone has notice how faulty this is finally.
Whatever he was doing, he clearly has no regard for safety... or bms ...
Comments will not help the video ever achieved high success
Yeah super important information. I too was looking for this in the comments. This should be the top comment.
Remember kids lithium batteries (like the ones in this video) will explode if not maintained properly.
So this explains why my batteries didnt work when I connected mine
I did this without watching any video so I thought that I was gonna get the longer lasting bank instead it was at it default state charging for 30 mins and working as it was with only one cell
i cant tell if your resoldering the nickel back on to the cells but doing that could offset voltages and they could get hot explode or just stop working

Приветствую! Во как! 4 из пяти аккумов муляж. С пасибо за обзорчик. Видео очень поравилось. Ты лучший!
OK. We've got it: the hard part of it all is soldering and de-soldering and re-soldering just to save a spare inch of cable or less.
Great upcycling job.
All looks great.

Id like to get a couple of those 18650's with sand inside as a novelty item, anyone know where I could get a few cheap?
I bought this power bank with punch of white cement 😁😁😁I think it's upgrade version
Nice video and upgrade! Those fake powerbanks with sand cells are no good.
Just a few points I'd mention:
1) This isn't a 20,000mAh power bank. With 5 cells, this would be 4,000mAh per cell. The maximum on the market is 3500mAh by Sanyo or 3400mAh by Panasonic, both very expensive, not usually found in laptops. Most 18650s from laptops are 2200mAh - 2800mAh when new.
2) It's not a good idea to just check for voltage and then solder together in a pack. You need to measure to at least 0.1V accuracy, preferably 0.01V or better. And you need to use a battery analyzer (e.g. a Turnigy Accucel or SkyRC iMax) to measure the capacity at a 1A discharge. Some laptop batteries are fine on voltage but hold very little capacity.
Thank you, exactly what I though. Pretty dangerous to do it like that...
Thanks yaar mera power bank kharab tha dekh kar Bana Liya verry verry nice
Bravo, complimenti!
Excellent choice of the music..... love it

i used to have a similar battery bank of 10000ma. I never buy incredibly cheap things with an expectation to be lucky enough not to be fooled.
u have not only to solder tue negative Battery Terminals together but.also the Positive Terminals in order to make a 5P(5parallel) battery configuration. right now u use effectively only the 3 batterys
Thank you for the tutorial now my power is gonna live long again
It looks like a dinamite block xD
Lol
Making Power At home:
1st Buy a power bank from market
2nd Open it and replace another batter
Your power bank is ready
Don't forget the number one priority.. adsense
Haha
@@ErikGinting what is adsense ??
@@RahimovBakhtiyor googlecancer.
Mene aise battery change ki aur 💯% working and good backup.thanks sir
Simple business achieved great success
Why cut the tabbing wire, the carry current better than the one single tiny resistor led you replaced them with.
I love the song
Same.

Nice, imported sand from china. 😂😂
Not China it's from India
@@iftikharahmed7879 😀😂

It says "local market", LOL
And for whoever is watching this video there is warning for You. Please, under eny curcume stances don't solder this batteries directly, I learned it hard way, I'm actually watching this wideo in hospital after one of my 18650's blowed me nearly straight in my eyes... NEVER EVER SOLDER ENY BATTERY DIRECTLY!!! AT LEAST SOLDER TO STRAPS!!!
Very good idea sir
MashAllah Excellent Well Done
I have almost desame powerbank. And 3 of 5 is fake battery with sand inside
Two of the most funniest part of the video:
1.sand inside batteries.
2.using resistors metal ends as connectors.😂😂
Also falling apart when soldering PCB lead
That's very good..I love it♥️♥️
Super! Thank you very much!
pretty much sure everybody believed in you after you open the first battery.
Please make your own power bank at home....
Hi frend
Please watch my channel 🔉🔉🔉🔉🔉🔉🔉🔉 ❤❤❤
Sand Nice... This gave me a smuggling Idea 😆😆😆😆
Bhai konse lap top ki battery use ki (mere ko bhi lake de sakte ho kya) 🙁🙁😞
Its not a very big deal because the Circuit is not builds for highly capacity battery
thanks sir.please give me detail about the background tone.it is just wow

So he bought a bootleg battery... Then decides to make it into an ied?
Charging is going to take a long time since its charged at 1A max(circuit limit).
2000mah x 3.7 x 5 = 37Wh
(37Wh + losses) ÷ 5w = 8 hours of charging for fullcharge.
The question is how long it will last?
Who cares? put it on charging when you go to bed. that's all. simple.
@@seitakikindadumb One 18650 Battery can charge almost one phone.
Make that 4K Mah each.
Heat is always draining these power banks faster than they should would wiring a small laptop fan to draw the heat away from it be viable?
Sir connection kaisa hai parallel or series
How the hell did they manage to put those sands inside it. The effort invested even seems to outworth the price of a single 18650 battery. What a heck!!"
-"Better than the market one."
Voltage: Am i a joke to you?
It was not charged
Problem now is the the original main circuit won't be able to fully charge all those cells. It will purse at a certain time and it will be back to Battery low quickly. I'm tried the same method
Always test the mah of the 18650 cells and only use the cells that are +-50 ma diffint ore els the bad cells will kill the gooed one’s

i wana make laptop powerbank 19V and 12 ampere, need to know about the charging circuit please.
You need a bms for that
@@CkmeLe0n what does bms stand for? Pls explain

Amazing content
best for beginner nice job...
No way it 20,000mah. There are no 4,000mah in a single cell of 18650 Li-ion. 4,000mahx5=20,000?? No way.. Single cell in laptop most 2,000mah or less. Used some more. Most likely 10,000mah or less.😁
Legends don't check battery voltages they use it directly 😂
Hahahaha am telling u
Lmfao
You should havs also put fuses in series with the batteries to prevent a cause of fire due to short circuit, its for safety!
Hola! Podria hacer lo mismo con una bateria de macbook pro 2007?
Beautiful music!
its 2:30AM and the only reason i am watching this video coz i like the music.. so can you tell the name of this music
Eita boa tarde amigo parabens muito inteligente
Nem para cantar essa bossa nova em inglês?
20000 mah? At leat show the readings using a multi meter
Multimeter doesn't show power capacity, dude
Can't read the energy capacity with a voltmeter...
Multimeter can't show capacity
Guys im just at the beggining, how do i find a battery capacity?
I also try that but the curcat
blow up
Circuit ?
Like ur projects. Could u make at low cost.???. The concept is an alarm. Sensor kept in the gate.when someone cross the sensor, Wirelessly alam at a distance of 50-100 meters at home
Music santiano very nice .

Well done your new power bank, how many times will it now charge your phone ???
If you fully charge it and left away for few weeks or months and then charge your phone , if it's still ok and charges and check how many times u can charge phone..tested it ???
I also bought a power bank at the market when I open it up 1 only battery works it has a 4 battery
"how to build a dynamite"😂
Everything 😂😂😂😂
Use the sand he removed 🤣
The "false batteries" in powerbanks are being sold at very cheap price in online stores.
Fake
Nice and also nice background music
That was hell of an unboxing video😂😂😂
Real silicon batteries, ha-ha! With silicon sand ...
I thought that he is the owner of the well known company MI 😂😂😂😂
🤫🤫🤫🤫🤫🤫
Brother I have 3800 mah lithium battery 4 can I use usb module you had shown for that
It's charging is not storing for the long time and when it's charging and charging, not completely full charge. So please give me some advice
Soo sad to know u had sand batteries
😂🤣🤣🤣🤣😂😂😂you just bought some sand
Hi, can you tell me what circuit is that?
Sir ye module se laptop ki 6 old batteries se power bank banaya mobile charge to fast hota hai lekin power bank charging hone me bohot ghante time leta hai kya karan ho sakta hai.kya batteries kam kar ke dekhu.plz reply me.
20000? Lol
There is, i literally have 1
think the title should be " how to swap battery's in your power bank " not how to make one........
This is a good idea!
Quite innovative!!
Not really... he just transferred the batteries from one battery pack to another.
Great
The music is very irritating after two times.
That true
Is it sand inside battery?
I have a black power bank like this but it's made by itek. Same shape and style, just black.
Each baterry must be 4000ma to do a 20000ma power bank, this is fake
I've seen 4K Mah rating on AA batteries, so...
Its max 10k mah
When brand new, maybe.. you never know the state of used laptop battery packs, without grabbing a battery analyzer and capacity test at 1A current to 3V.
3500 mAh 18650 x 6 = 21000 mAh at 10 amp max continuous discharge
It's a good video
