Also, I have the answer to 6s vs 7s. Everyone is afraid to use 7...
...because 7 8 9.
And 7 is still hungry, i guess?
Thanks for using your voice to walk us through it. Some channels just want to show pictures, like that is enough information, but it isn't enough for me.
I appreciate you taking time to do it right, walking us through the build. I have a driver-on-board 100w LED, but i can still use much of this information for my build. 👍🏼
love your work , please make DIY Spot welder for batteries
Upvoted for the furry assistants.
you said that in a weird way, didnt you?
Fan From philippines, Waiting For the part 2 😊😊😊
Yes
Excellent project
Awesome video as always👏🙌
I love your videos great dedication towards channel ❤️👍
What took you so long my dude I missed you
Btw you should colab with electroboom one
Edit: thanks for the heart
As always interesting projects :D
Gretings from Serbia. Like your videos :)
Niceee, new video!
Hi bro , awesome video ! Welcome back , finaly !!
Great video. ☺️
great video!
2:05 What an actor!
6:25 What an actor!
11:41 just apply a drop of thermal paste and let it like that. If the oaste gets hot, it will spread evenly.
Superb 🤩🤩
Haha, ElectroBOOM will be happy with your experience of a blown capacitor😂
Anyway, nice video; keep them coming... We love them, as well as your sense of humor👍
And I blew up my charger capacitor after this comment bruh
nice work
Good project sir
finally a new vedio wohooo
His back ❤️
You got a new subscriber
amazing bro, it's look s like factoried product
LEDs are a current driven component. The forward voltage is dependend on the current going through the LEDs. To get a more stable output i suggest using a led driver next time. Great vid BTW realy liked it.
In your die pack of the LEDs u can het similar output out of all of them if u set a current limit and no voltage limit.
He's back 😋
nice
Came for the electronics stayed for the comedy commentary 😄
oh buddy, don't lie about the reasons for making a multi-part series... this is not a job interview, you don't have to pretend that working at a warehouse lifting boxes was your life-long dream that you feel passionate about. Watching multi-part vids is the cheap man's patreon - still a way to support your channel.
When will video powerbank for laptop will be uploaded?? Eagerly waiting 😀
Hey man, from where are you?
7:55 electroboom is looking at your blown converter
fantastic bro
4:29 is that jigsaw brands any good ?
yes it's good.
Really good video! From where did you buy the Lion cells? 5:40
I added the parts list in the video description. these are the cells: s.click.aliexpress.com/e/_Aq8Rnl
Use spot welder to stick the batteries together, soldering iron is for well experienced elecctritions
I tried to do this but it didn't work, when I tested the battery it let out a small explosion! Careful with li-ion cells...
that's why I got the cells with nickel strips already attached. they can be soldered much easier and faster and the cells will not heat up.
That's safe btw
i have an idea for a good spot welder with a bank of super-capacitors with transformer and circuit to charge them just make sure to work safe with them cause charged super capacitors can harm, for solder nickel strips to batteries however there is no need of huge capacitors but i suggest using modified microwave oven transformer remember to be cautious cuz i want to keep watching new videos from you friend :)
Is it because you have a higher range of luminescence? Since you're using a step up converter, the lowest voltage you could have with a 7s battery would be to high for your needs. Or maybe it's easier to charge, maybe you don't have a 7s li-ion balancing charger.
yes, you are correct. the complete reason is because a 7S battery pack has a maximum voltage of 29.4V and I want to adjust the voltage (with the secondary potentiometer on the boost converter) between 27.5V and 30V. with a 7S battery pack I could not have done that.
Summer is here...Can you make a video on a mini Fan ( Rechargable)
cool
i love ur soldering gun ,please make a tut about it and a diy from making one , i am from sudan no more tech here we really need this gun 💗
hi. the soldering gun is not home made. it's a powerful Romanian made soldering gun from the '80s and '90s. it's not made anymore.
is it because 6 cells fit nicer in a package? or one of the cells came dead?
no
love the T-shirt Sorin, Any ideas on what it might mean??? they say it might be a song or poem! or even a spell. any guesses??? P.S the 6S batteries were closer to the voltage you wanted/needed...
hi. I like the T-shirt too, but I don't know what it says. maybe someone from Greece can tell us.
Always waiting for " wan xhandret" accent 😎
Hi bro. I made ups for my router and modem. They works fine, but only problem is they restarts when power cut. How can i solve this ...i want it to run continuosly without restarting.which capacitor should i use (value)..
hi. you can watch my part 3 video about the UPS built, I test a few ideas to switch faster on battery power.
@@Sorin_DIY ok. I will check that...thank you.🔥
@@Sorin_DIY i just watched part-3 video, so i should make relay to Klick faster and use high capacity capacitors to smooth the output when switching.
yes
@@Sorin_DIY ok ! thanks bro
Using 6s instead od 7s because od the size? Or maybe because the MAX voltage of the LED is 30v and at a lower voltage it Draws less current and is still bright enough and also generates less heat? Its just my guesses
no, sorry :)
How to measure battery pack capacity..?
If per cell is 2200mah and I made 5s 21v battery pack with 10 cells so how I measure there's amps and watts.
the capacity is measured in Ah, if you connect the cells in series, the current and capacity remains the same, only the voltage is added. so your 5S battery pack with maximum 21V has a capacity of 2200mAh (2.2Ah). the energy of the battery pack is = capacity*nominal voltage = 2.2Ah*3.6V*5cells= 39.6Wh.
@@Sorin_DIY thanks Bro
Maybe you would enjoy the channel by "Luca" discussing the "mini spot welder". They are only around 30 EUR and they work very well with a small modification.
I have one of those battery-powered welders. Quite adequate for occasional use, and fits in a tool bag. I use it at work to change out cells in Chromebooks.
I like you cats 🤗
let me guess you went with a 6s battery pack because the boost converter boosted the voltage around 32~ volts at its lowest setting
Good point - I was going to say that he didn't have an 8S plastic base and covers. Thinking about it, a 8S with a current driver would be a better idea.
not exactly, but you are close.
Still waiting for the DIY Spot Welder without using any monstrous transformers :D
I want an video or reply how to make 100w rms or 150w rms bluetooth speaker it is wireless and with radio 2.1 for my birthday tell me how to make it my birthday april 25 please
7:56 hahaha
He is also my favert
can i charge 18650 battery's with a pcb from a powerbank?
yes
I guess you used 6s instead of 7s because you wanted to be able to dim the led below the 7s voltage with only a step up converter
yes, you are correct.
Part 2 please.
it will be ready in a few days
Because u can balance using imaxb6
no
Sorin, please make more videos. If you don't have any build ideas head over to reddit and see some photos or something and make a subreddit so we can share our thoughts and build ideas with you.
Keep it up sorin! Ur Almost Close To 100k Subs! I Will Always Support you. And Can You Upload The Second Flashlight vid?
I'm working on it
Good job
But you need led driver for this led chip by this converter led life cycle will decrease
Can you make a project with piece's from emag?
you can find on emag some of the components I use in my videos, but not all of them. so I can't use components only from emag.
ok
I think you used 6s battery because when the 7s battery is fully charged you can't adjust the led voltage below 29.4v
correct
I think it's because that you don't have enough space for the cooling fan and other components.
I do not understand can not use a potentiometer of 10k?
the 10k potentiometer will set the voltage between 12-35V, so you need to be very careful and adjust the potentiometer only about 2mm to dim the LED. if you add a 1k potentiometer you will have more control to safely dim the LED.
@@Sorin_DIY So if you put a resistor of 10k In the middle leg of power 2, does it solve?
Can you just leave one potentiometer without adding another?
yes, but it will be difficult to adjust the voltage for the LED.
@@Sorin_DIY I only have a 10k potentiometer and I have two resistors how do I install?
10:40 "Can you guess why?" Err... Would be the battery pack's geometry, right?
no. you can find the answer in the part 2 video.
@@Sorin_DIY Oh, yes. It's a Step-UP-only converter. Makes sense. 😃
Brother i dont have 1k Pot, i have 10k pot what to do?
that's not good. you need a 1K pot.
10k pot with 10k resistor will work
Salut Sorin
That fingerprint show that "made in China" and "I love you" don't offer any warranty. :)
I don't get many reminders for your channel. I think it's Odd because others show up way to much.
I know why you change your battery to 6s instead of 9s
With 9s battery the boost converter will be very efficient but the buck converter will be very inifficient and produce a lot of heat
With 6s battery the boost converter will not be that efficient but the buck converter will be much more efficient and less wasted power and less heat produced by the buck converter.
no, sorry :)
the reason you went with 6s instead of 7 is space limitation
am i wrong?
no. there is another reason :)
6s, because the charger is 25 volt?
no
@@Sorin_DIY 😢
salut.. construiesc si eu boxe diy.. poate facem cumva un schimb de experienta.. pentru ca am vazut ca esti artist in electronica.. eu sunt artist cu lemnul.. poate facem ceva impreuna
Hey Sorin , where is part 2 , I am waiting for a week
it will take one or 2 more weeks to finish the video.
@@Sorin_DIY ok
You used 6S instead of 7S because you didn't have holders/it wasn't symmetrical
hay sorin
It's been so long...
Love your projects. I think you need to get a better microphone.
Sorin electrical nerd is to good and to big and and to famous to respond to any of you small people in the comments.

After 2 months
How many cat's do you have ❤😍
we have a total of 5 cats divided at 2 households.
Where is part two buddy?🙃
it will be available soon.
um, try making a 600 watt one lol
pls share diagram 10k pot and 1k pot

@@Sorin_DIY Brother i dont have 1k Pot, i have 10k pot what to do?
becasue 6s looks more sgsy
Let me guess you destroyed one of the cells beucause you set the charging current to 2A
no
Do not use your finger to spread termal paste, skins have oil on thet is not very good termal conditor.
You used a 6 pack rather than 7 due to space in the housing
no
6s battery-pack because 7s would look unsymmetrical and ugly :D
no
Because the plastic thing only has six holes
I see that this flashlight would be very bright but, if I did my math right, you would only have 66.6Wh available. I can see you'll get about 30 minutes per charge, if I'm right.
I think it will last little bit more than 30 mins. I think it is betwwen 35-50mins
@@moya9450 With a little research, 35-45 minutes would be its run time.
hi. according to the seller this type of li-ion cell has a nominal voltage of 3.6V, this gives the battery pack an energy of 64.8Wh (3Ah*3.6V*6). in the video I mentioned by mistake that it has 75.6Wh... ups :). but in reality I think that the cells have a nominal voltage of 3.7V, not 3.6V. so the energy should be as you said 66.6Wh. I say this because the flashlight lasts 52 minutes at the highest intensity. it may sound ridiculous, but I timed it twice.
the LED doesn't use 100W, that's the maximum rated power, but it's recommended to power it with less, especially because the LED is not perfect, as you see in the beginning of the video, the LED chips don't light evenly at low voltage. that's why I power it with maximum 3A (29.3v*2.99A=87.6W). I tested it 10 minutes on the bench and the current remains stable.
but this still doesn't explain the autonomy. 66.6Wh/87.6W=0.76h =45min. and this is assuming that the converter works with an efficiency of 100%, which obviously does not.
so I'm guessing that the current used by the LED fluctuates and may decrease over time.
or another explanation may be that the capacity of the li-ion cells increased slightly after several cycles. I got maximum 3000mAh from these cells. but I see in the reviews that some other buyers got more, even 3137mAh.
otherwise I can't explain at the moment the 52min autonomy. it's a bit difficult to dismantle the flashlight and test the power consumptions inside, but I will probably do this in the future.
and at the lowest light intensity it lasts for 6:10 hours.
@@Sorin_DIY that mean a little less time, about a minute less.

It'll probably look ugly and a waste of space if you use 7 batteries assuming you only have 2 battery holders
no
