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.

Durka Durka me solder on lithium battery and use unbalanced cells and damage battery is good no?

Charger?

Très bien 🙌

Very good work

ខ្ញុំមាន3.7និង9v ❤❤❤❤

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

Bro price kya Hain ek battery cell kaa

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.

!!! Can this assembly be used with a 220V inverter?

C’est nickel 👌

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.

Udaya❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

Admin buat aki dari baterai langsung ada casnya biar kalo Soak biar di cas gimana caranya

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!

How can I have this change ter

Wrong bms wiring blast 😂😂

Please ampare check!

Isko charge krne k lia konsa charger lage ga

Por favor cómo se llama la pieza que le puso al lado de la batería por favor

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

Las baterías son de cuantos voltios cada una y ampage

Did you test the capacity? mAh of the cells?

How to charge this battery?

🔥

Can it be use as a replacement for UPS battery?

Hi, isn't it a problem to use different cells in one package?

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

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...

Interesting ❤❤

Nice 😊

30ah how much 2000mah battery cells use

Brother, Greeting could be charge this device in solar panel??? please let me know???\

What is the maximum instantaneous current that the package can supply at 12Vdc? Can you start a car engine in an emergency?

Your video presentation is simple and good. Congratulations !! I'm a subscriber to your channel.

Big fan sir 😮

Bhai ye battery mujhe dedo

bro built a bomb....

Kya baat hai bhai aap ek underrated scientists 👨‍🔬 ho 🔥

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.

I like your all videos

Keep it up bro

Absolute amateur!!!!

What gadgets

Nice work

You do a biggest mistake. You should use balanced bms for cell balancing
