Horrible idea to show all people your "skills" via internet...
1) not shown: testing of all cells of their capacity and internal resistance.
2) not shown: do all shown cells provide the same cell chemistry? This means, that all cells can support with same maximum discharge an charging current...
Normally the cells provide a serial number printed on. So not only the dimension (18650) is the thing to be paid attention, more the less the numbers beneath chraracterize their chemistry and further their electrical characteristics.
Also you mix all different coloured cells together - did u do so randomly? All the cells seems to be used cells....
3) not shown: matching of cells. The best BMS can't help if one of the parallel cells is dying.
4) shown: soldering cells directly with soldering tin.... high temperatures (250-300°C) hurts cells. They should be spot-welded.
5) no temperature control/sensor or fuse is provided to the BMS or inside the battery pack.
6) no thermal prooved isolation tape is used to isolate the whole package. Only 5cm of Capten tape for BMS...
7) but not enough - the "sealed" battery pack is packed into a used and closed old battery container. No thermal airflow possible. Do you want to kill the pack when power-treated in your application?
Last but not least:
8) Min. 10:13: you soldered the 8,2V BMS-point to the 4,1V bridge at the cells.
This shows perfectly that you really know what you are doing. NOT!!!
Also you do not tell people that this battery can replace a normal lead battery block.
A lead battery can be charged up to 15V without being harmed. If you replace this in your vehicle with your DIY-battery you have to consider that the maximum charging voltage must not be higher that 12,6V.
So every voltage regulator in your vehicle will shoot this battery!
Wish u good luck and happy time - finding the error in this battery pack or when burning down in a Li-Ion fire.
You are doing a good job - NOT to support the way going electric.
It's your fault when newspapers are full of reports when electric vehicles are burning down...
With all of the comments about unmatched cells and the BMS, I'm surprised no one has commented on the idea of soldering directly to the lithium cells.
No problem if using a 25W and fast, but low wattage iron and long warming you can damage it. did this for years and never encounter a problem , but then i have been soldering for 48 years now
I pray before... rsrsrs
exactly...
those cells must be loving all that hot glue and huge globs of non super-conducting temperature solder
Can this be used in Suzuki Activa Battery replacement?
You just showed everybody how to wire up a BMS wrong 4.2 to 8.4 and the 8.4 position is wired to 4.2 I don't understand how you mess that up the BMS is designed so you fold over the nickel to the respective points
❤
Yess u r right im also thinking about that
true
Please reply im building one with Samsung cells 18650 same way he did + then - but lmk how i should wire a bms like what was it supposed to be on lmk
So far i just glued the batterys together the same way he had them im still a beginner on building battery packs but ive came along way
Still learning how to wire up a bms
What bms is used?
Your video presentation is simple and good. Congratulations !! I'm a subscriber to your channel.
Thank you so much
Nice bro❤
Can it be use as a replacement for UPS battery?
This shows in great details how not to do it. Never solder. Do not use unbalanced en different batteries. But you fail to mention that you need a special charger. Do not use a car or ordinary charger. It is risking your life.
People when you have no idea about the circuit you should NOT attempt to do this.
The idea is great to use an old box but please rsalize that the battery is not compatible. I also do not see any temperature sensor. It is only good when you send it to Putin as a gift.
is it useful to bike cb unicorn?
Isko charge krne k lia konsa charger lage ga
Big fan sir 😮
Durka Durka me solder on lithium battery and use unbalanced cells and damage battery is good no?
Did you test the capacity? mAh of the cells?
Nic bro
Tnx bro
Cold solder joint .
Brother, Greeting
could be charge this device in solar panel??? please let me know???\
Admin buat aki dari baterai langsung ada casnya biar kalo Soak biar di cas gimana caranya
!!! Can this assembly be used with a 220V inverter?
ខ្ញុំមាន3.7និង9v

Good 👍 job broo
Thanks for watching
@@MakerChannelofficialWhat type of solar panel would I need to change that battery pack?
Yo lo ise pero con 4 celdas cada una con 6 batería as ya armada da un poco más delos 14 voltios porque al aserla de 3 celdas con 8 baterías no mantiene el voltaje por mucho tiempo cada batería quedó con 24 baterías aún no les pongo bms pero si las consigo lo are
Besser wie ein blei akku
Sir maine 20 ka BMS laga ke 2200 mh ke total 15 cell se 12 battery bana liya. Kiye yeh 20 ke BMS hain usse saare battery full charge hoga ya nahi? Please reply i am India from Assam State!
Yes, adjust voltage and current 12.6v, 1.1a using xl4015 or xl4016
wleding on lithium cells and preparing pre welded nickel stripes are unsafe and losse a lot of time....now a spot welder cost is about 30 dollars.
Lack of knowledge but going to guide others. :v
30ah how much 2000mah battery cells use
Un-matched cells are NOT SAFE TO USE IN A PACK!
Yes bro, he join cell of different capacity but same voltage it may be dangerous
C’est nickel 👌
Las baterías son de cuantos voltios cada una y ampage
Bro price kya Hain ek battery cell kaa
Charger?
Gehäuse 😊
You do a biggest mistake. You should use balanced bms for cell balancing
pls show the diagram
How can I have this change ter
12v , ? Ah ...🤔
This BMS gives me a few problems, after the battery is charged 100%, the voltage output becomes 0.3v less than the battery voltage and when I connect it to a charger it doesn't charge, for it to start charging again I have to short the positive of bms with 0V of the battery giving 12.6v in output and it charges again, please help to fix this issue
and this bms does not have a short circuit protection, the transistors will burst if you short the output
How to charge this battery?
Por favor cómo se llama la pieza que le puso al lado de la batería por favor
How much current & voltage for charging the battery ?
12.6V ,1.5A
9:51 wrong bms connection, you connect the 4.2v to the 8.4v terminal, and then you connect the 8.4v to the 4.2v terminal.
12v nhưng 1.5ah ok
Hi, isn't it a problem to use different cells in one package?
If it was the same milliampere for me, there is a problem
It's a problem... the balance of cells not work
Is that all cells are 2000 mah? If all cells are 2000 mah it means battery capacity is 14Ah not 15Ah
I'm lost. I thought because these appear to be 2000mAH @ 3.6v batteries then it would be 12.6AH for 21 of them at 12volts.
E = Watt * Time
= VA * Hr.
Ah = E / V
E/3.6v = 2000mAH (formula to interpolate and solve for E; 1 battery energy)
E = 7200 milli watt hours
E times number of units = Total E
7200 x 21 batteries = 151200 milli watt hours
To solve for 21 batteries at 12v:
mAH = 151200/12v
12600 mAH = 12.6AH
I'm guessing you won't get more than an hour from those batteries though.
Das nenne mal ein accu Pack
genau.
Da muss man nicht bis Silvester warten, bis diese gezeigte Scheiße abbrennt.
Höchst unprofessionell und auch voller Verdrahtungsfehler.
Not recommended, das nachzumachen.
Nicht mit dem Kleber
What is the maximum instantaneous current that the package can supply at 12Vdc? Can you start a car engine in an emergency?
It depends, what cells you have, Iam making now a pack with 4s3p lifepo4 at 12V and 7,5Ah, its about 150Amps, so sure, you can start a car with it (Iam making it for my wifes motorcycle)
@@klukzgaraze Thank you for your quick response. In Brazil they sell an emergency device for when the vehicle's battery discharges. It's the size of a VHS tape, very small, and costs something close to 50 U$, very cheap. It remains to be seen how many deep discharges it will withstand. I would like to know this approximate number. Thank you and best wishes for more success.
I do not understand the BMS wire connection.
You're right, the guy in the video swapped the 4.2V and 8.4V connections for the cell balance.
The batteries are connected 7 parallel clusters of 3 batteries connected in series so the BMS needs the (-) at 0V, the (+) of the same battery at 4.2V (which is also the (-) of the 2nd battery), the (+) of the 2nd battery at 8.4V and the (+) of the 3rd battery at the 12.6V and all the other clusters are getting the same voltages.
How to charge? Where is charging module?
Solar
Is it safe to do this mod i am concerned about fire
So am I he connected it up totally wrong I don't know how it didn't smoke
LOL lucky bastard 😂 😂
How to charge?
XL4016 BACK CONVERTER USE KIJIYE HAR KISIM KI BATTERY CHARGE HOGA.
You used 21 pieces of 18650 which go for about 5 euro a piece to "repair" a battery that costs 15 euros brand new. Maybe you can buy some chinese scam batteries which are 50/50 sawdust but it will still be too expensive.

Bhai ye battery mujhe dedo
Ye charge kaise hoga fir
Woher kommt das nix
three different types of cells and he soldered that bitch with what looks like a 30w soldering iron. that's not a battery, more like a time delay bomb. he probably took all that from his job in some factory in India or china... like johnny cash. took it one piece at a time and it didn't cost me a dime. 👌👍
Mi hai fatto ridere😂
Nel complesso utile
you spend way 2 much time on the obvious/simple/repetitive. Painful 2 watch. I'll force myself to watch this vid to the end but I won't come back.
Und was?
Boss saan ka po nakabili ng legit na lithium 3.7 na battery.maraming salamat po.god bless and follow na po kita and subscribe
Got an old battery from a laptop repairing shop.
actually, I just can't watch boring incompetency. bye frvr
Wrong bms wiring blast 😂😂
तो आप हि बताओं ना right ky he 😂😂😅
PIPI
This is not 12v battery it's 11.1v and 12.6v fully charge.
12v battery is 12.8v and 14.6v fully charge.
یہ بندہ بغیر کچھ بولے غلط وایرنگ کر رھا ھے۔۔۔ اپ کا نقصان کراے گا۔۔ پلیز اسکو فالو نہ کرین اور نہی ایسی بی ایم ایس وائرنگ۔۔. شکریہ
How NOT to make a 12v god knows what Ah it will be lithium battery. The BMS will never work the correct charging state the battery or state of discharge.
You would think YT would care about YT video content and keep people safe from these dangerous videos.
Absolute amateur!!!!
بے کار محنت ہے ایسا کرنا: وجہ یہ ہے یہ پرانی بیٹریاں بیلنس نہیں ہوتی کسی کا کرنٹ کم کسی کا زیادہ ہوتا ہے۔ مثلًا اگر ایک بیٹری 1200mah کی ہے اور دوسری 1600mah کی ہے تو اس کو بیلنس بیٹری کہا نہیں جاتا۔ اور ان سب بیٹریوں میں سے جو کم mah والی بیٹری ہوگی وہ فوری طور پر یا ایک ہفتہ کے بعد dead ہوگی اور ساتھ دو یا چار دوسرے بیٹریاں بھی dead کرے گی۔ تو سارا محنت ضائع ہی سمجھ لو!
