I really enjoyed this. I watched the whole thing. I love the way you have it close up while you're working, it helps me learn exactly what and why you're doing the things you're doing. I couldn't get this info from other videos, but your silent approach and close ups help explain a lot.
Master Yousun, that was a marvelous assembly. Appreciate your meticulous attention to each section and clean set up. A brief description on the BMS type and model and charging voltage would enhance the whole video much better. Last but not least...... please describe your SPOT WELDER. Show us, in sequence, how you made it, what parts were used and the technical data. Thanks again.
Very good indeed! Despite the absence of audio or descriptive subtitles, it was possible to understand exactly how it was done and a great level of finishing of the work itself! Perfect, congratulations!

copper has one third of the resistance than nickel and can be found everywhere for cheap- I would solder at least the parallelization wires using solid copper wire. Then I cover all my contacts with transparent neutral silicone to decrease the risk of accidentally shortening or effects of moisture...
Perfect this montage the video is very datica. I believe it was the most esplicative I found in yuotabe. I'm wanting to ride a 22S P12 84V 30AH and I was missing this video. thank you
I like the natural background. I watched the whole video but there is something you didn't show us. The connection of the green wire to the BMS. And also, why is it 47V only?
@@yousun2827 i still like the power meters on the battery because i use the battery for more than just a bike discharge. i bring them inside and hook them to other batteries and solar chargers as well as using them to power other devices at home and knowing the battery levels in any and every situation in realtime is much better
If I were to use a step-down converter to convert the voltage output to 12 volts, how many "amp hours/ah" will it put out at 12 volts versus putting out 20ah at 48 volts ?
Isn't there a faster way to connect these batteries for 48V 20AH? My 12V 20AH sealed lead acid batteries in 2 boxes only has 4 battery connections and 2 connectors for easy handling to and from the trike. Just connect the 2 boxes for 48V and a connector to the trike controller. They are charged On or Off the trike and charged at 48V 20AH. I have only lost 1 12V battery in over 2 years of full discharge cycle. I just replaced it in place and the pack is on its 8 month of use now, getting about the usual 60km per charge.
I noticed the video is around 17 minutes long. How long did it actually take you for the entire process? If you were able to do this under an hour I would definitely be impressed with your skill and patience.
Where did you get that cell staggered black plastic spacer. We usually find square plastic spacer. with yours, it seems we can pack more cells in less space ?
I had made a lithium ion battery pack rating 14.6v 30a with the same type of bms rated 12v 30a.can I charge it with a 14.6v 3a smps or i need a same rated lithium battery charger.please reply fast
Is there risk of electric shock to hands when cells terminals are physically touched whilst battery cells are joined together in series at high voltages 48v and above?
Why you are not using fuse in the positive side of the battery? Is this safe? There is some Nickel strips with fuse incorporated to the positive side. Why you are not using buss bar?
Hi, thanks for an interesting Li-Ion Pack building video. I build my own, so I understand the time involved and extra time to film it. Some comments; Pros; Nice professional build using what looks to be top shelf spot welder and equipment. I like the way you built the layout of the pack and left cell holder openings that are protecting the connections. cons; Imagine the work required to take that pack apart if there is ever a bad cell or poor spot weld. Note; I did notice you check EVERY singe connection to be sure they were all properly welded. Once again, color code wire problem. BTW; the DC electric world as I've always know it is Red is Positive and Black is Negative. China doesn't seem to have a clue about that. Is that Blue wire positive or (probably) negative. And I can't really tell where it is connected on the BMS. VERY important steps you left out for us DIY folks. You show x2 48v voltage tests but don't show where the connections go! :-( Also, between the shrink wrap, Barley paper and tape, you've sealed it so well, there will be NO cooling air able to circulated around the cells. Here in the desert of Southern California, that could be fatal to that pack. Don't take my comments wrong, it's few and far between seeing decent videos on pack building and all involved. I give you high marks and only hope to see more in depth info on the subjects I addressed. cheers Boots Langley La Mesa, ca

Hello, where did you buy the nickel strips to assemble the cells? Are they ready or did you prepare them? and the point welder, you could give me a reference Thank you
Looks nice, but is that BMS going to balance? Looks like this one (like most) only starts balancing around 4.2 volts per cell. I think it is good to charge cells to only 4.1V for better lifetime, but now I think the pack might not get balanced properly?
When the internal resistance of the connection between the batteries is low, the battery pack voltage will be very balanced. I will take apart the measured voltage after one year.

I prefer individual cell fuses incase of a bad cell. Tidy job, impressed.
How do you go about individual cell wiring? Is there a video as good as this documenting it? Thank you.
this is an awesome video i learn a lot on how to weld and the connection of the battery awesome job.

If I were to use a step-down converter to convert the voltage output to 12 volts, how many "amp hours/ah" will it put out at 12 volts versus putting out 20ah at 48 volts ?
Buck efficiency, About 18Ah.
Would you please list all the material you used to do the pack?
What kind of welder are you using? Good video. Good luck.
Hi - what is the model / PN of the black plastics cell holder? I like the edge and spacing... most are just plane round on Amazon.
This product is relatively rare, and it is no longer available.

We usually find square plastic spacer.
with yours, it seems we can pack more cells in less space ?
Do you need it? I can sell it if needed.
So how many of these would power something like a super soco?
good job. Once discharged how will you load it?

14.6V 3A charger.
Did I miss where the charging points were?
Is there risk of electric shock to hands when cells terminals are physically touched whilst battery cells are joined together in series at high voltages 48v and above?
If the hand is wet, there is a little bit.
Why you are not using fuse in the positive side of the battery? Is this safe?
There is some Nickel strips with fuse incorporated to the positive side.
Why you are not using buss bar?
The use of fuses causes serious heat generation, which affects efficiency.
Wonderful work, are you using a professional spot welding machine or it's DIY? My DIY welding is not so good.

Yousun please do reply is your 18650 battery pack works perfectly aur it has great capacity loss after a year or 200 cycles or charge and discharge
great project!
I want to know..what is that he is using to solder the bat together?were could I buy it?
I did not understand.
Hi,
thanks for an interesting Li-Ion Pack building video. I build my own, so I understand the time involved and extra time to film it.
Some comments;
Pros; Nice professional build using what looks to be top shelf spot welder and equipment.
I like the way you built the layout of the pack and left cell holder openings that are protecting the connections.
cons;

Is that Blue wire positive or (probably) negative. And I can't really tell where it is connected on the BMS.
VERY important steps you left out for us DIY folks.
You show x2 48v voltage tests but don't show where the connections go! :-(
Also, between the shrink wrap, Barley paper and tape, you've sealed it so well, there will be NO cooling air able to circulated around the cells.
Here in the desert of Southern California, that could be fatal to that pack.
Don't take my comments wrong, it's few and far between seeing decent videos on pack building and all involved. I give you high marks and only hope to see more in depth info on the subjects I addressed.

what is the name of the tool you are using, to attach the nickel plate to the battery ?? please help me
spot welder
@@yousun2827 okay, thanks
Why did u place the cell in zig zag style..why not opposite to each other, wat is reason pls explain
This is arbitrary and has no special reason.
Great video
I was wondering if you can make two cells like the one you made and connect the BMS parallel to each other ?
Two batteries can be connected in parallel with the BMS, provided that the voltages of the two batteries are close.
@@yousun2827 they should be at the same voltage level but after time of use it could change right ?
If the voltage changes indicate a problem with the battery, it is usually the capacity that changes.
@@yousun2827 thanks
