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
Great video! The content is top-notch and very easy to follow. I learned a lot about making a 12v battery with 18650 cells. Thank you for sharing your knowledge with us!
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
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?
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.
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...
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!
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.
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.
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

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.
Estás poniendo los cables al revés y otra cosa si pones todo en serie no es 12 v tienes 14 o sea 7 y 7 y en medio 7 en positivo si cada celda es totalmente cargada de 4.2 v hay no hay 12 voltios
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.
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. 👌👍

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

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.

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.

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