@Calvin Sullivan i really appreciate your reply. I got to the site through google and I'm trying it out atm. Looks like it's gonna take a while so I will get back to you later with my results.
This is brilliant nice work man. I love youtubers that list all the parts in the description as well too thanks for that. maybe you could install a mini fan with a thermal monitor activates in when it reaches a certain temp.
A fan in use when it is getting charged is a good idea, but when this is being discharged in its role as a battery pack for a mobile device the fan would draw power off of the battery - that would drain the battery a bit sooner and usually when you are on the “backup battery” you want every last bit of power for the mobile device.
@@stevebabiak6997 I completely agree but the lifetime of the components would last longer if you kept them cool, guess its a choice of either longevity or efficiency.
Just a small feedback about this project. You better use smaller Amp BMS for this because you only use 1P. The BMS is basically not protecting the cells enough if you paired 1P pack with 40A BMS. If the component faulty and drain like 30A semi-short circuit, then those cells will get hot and boom. Not the best explanation, but you get the point. Love your videos Sorin!
Hello everyone! I am new to the electronics and circuitry space. I was wondering a few questions on this project, as I have been doing some research. A few questions: 1) What is the voltage inputted into the step-down converter before each usb module? It seems to be abou 24v but I'm not sure. 2) what is the full capacity of the 6s batteries? I thought 6 batteries in series would result in 6x the voltage. All help is greatly appreciated and tysm!
Hi. 1) the 6S battery pack voltage is between 25.5V and 16.2V 2) connecting the cells in series the capacity doesn't change, so 3200mAh. the voltage adds up, so also the energy.
Good to see a video from ya! I hate to say it but your friends are a little transparent... Lol So was the mug shot from the Airport? :-) Loved the video, it was a great project. I have several projects that I am going to have to update with Type C Charging ports. That can be added to this one as well! Thank you Sorin for the video and stay safe my friend! Hello from Indiana USA... LLAP
Looks like a good project, a better box than I ever thought of using! I would worry about the two cells under the power converters getting hotter than the others and aging/ losing capacity faster while fully charged. Then they would start to become unbalanced, relying on the BMS board protection limits.
hi. the 2 cells don't get hot, I put 2 layers of sticky foam tape between them and the modules. plus the DC converters have heatsinks. the converters don't produce enough heat to affect the cells. you can use bigger heatsinks if you're not sure of that.
from the electronic point of view, there's a lot to be improved in this however, your Romanian English accent is just great, I am subscribed :D I am going to watch some of your old videos, try to check were you got some "incorrect information" from and do my best to pass you some constructive practical advice, keep it up!
Sorin at the airport: "Just a powerbank I swear!" xD Also, I cut my mirror and my gearshift off in my car because I need as much space as possible xD Nice video!
Great to see more videos from ya!! : ) You Always Come Up With Some Really Cool Designs!!!! : ) HUGE P.S. I LOVE SEE THROUGH BOXES AND PROJECTS. (even heat-shrink tubing) so im with ya! there 100%
Man, this is the most efficient and reliable powerbank I've ever seen!. But I want to use 4 18650 in parallel. Do you know what charging board I should use using a 33 watt charger to charge 4 18650 in parallel?
Nice video but which one is better for making power bank a series battery and using a converter like in your video or making a parallel battery and direct to power bank module and not using a converter? is that the same phone can charge which is the best?
so, sorin, you made a great film - some electronics under transparent cover, many colored bright leds and even radiators!!! now the easy question: if there are radiators, they conduct heat, yes? and where goes all that heat without any holes at all inside this small box? not afraid from lithium fireworks? they are very intensive and burn so well all around, if you never saw them. summary: no holes for exporting the heat out of the box, but enough eyecandies - anyway it looks good for youtube content.
You're overreacting. You are implying that by adding radiators, it will be more heat inside the powerbank. No, the heat is generated by the ICs, so if you have a problem with the heat, you should take it on the ICs. 15W of heat inside the powerbank is still 15W of heat, with or without the radiators. The modules are produced without heatsinks. I added the heatsinks as an extra precaution, to help the ICs dissipate the heat faster, not to cool down the entire powerbank. Inside the powerbank there is enough air to absorb the heat generated by the small ICs, the li-ion cells are not affected. And instead of a 70°C IC, I prefer a 40°C IC+heatsink. I think you should be more worried about your sealed mobile phone getting hot, including the battery, while it's fast charging or super fast charging. regular powerbanks don't have venting holes either. And what about your 75W laptop charger? it's sealed closed with very little space inside, to absorb the heat.
hi. it depends on how you're going to use the battery pack. if you want only a 5V output, it's better to make the battery pack in parallel, because it will have a better efficiency. but if you want a fast charging output with up to 12V & 2A (24W) that will put a lot of stress on the battery pack and converter, because it will draw a lot of current and will work at a low efficiency, probably between 75 - 85% (let's say 80%). if you make a 1S6P battery pack, it will deliver a lot of current, but the voltage will decrease to 2.8V or maibe 2.5V, depending on what protection board you use. so when the battery pack it's almost discharged and the converter will try to deliver 24W, it will draw from the cells 24W/0.8eff=30W; 30W/2.8V=10.71A. so the fast charging module will draw from the almost discharged battery 10A, maybe more... that's a lot! the fast charging module and battery will get very hot and the overall efficiency will be very low. but with a 6S battery pack you don't have these problems, because the converter needs very little current from the battery.
@@Sorin_DIY OMG Really Sorin u replied me OMG i am a big fan of u Btw I was going to make a 3s2p battery pack and a 300w buck converter to regulate to only 5v and 2a. Is it a good idea. Pls if u reply this I'll probably get a heart attack!!
Hi Sorin, loved your vid. It's now been 2 years since you built the powerbank. I would very much like to know if it has given any problems. I am intending to build 6 of these, following your instructions. I have purchased all the same components as in your parts list except for: The case I intend to 3d print, and the BMS I chose instead to go with a 30A BMS. I know very little about this subject. This seems like a good way to learn. The reason I want to go with 6s is that I bought very cheap, 60 sets of used 6s packs. Each pack comes in a hard case, and the batteries are already connected in a 6s configuration. Thus it seems to me that a lot of the work has already been done, so long as I stick with 6s. I am worried about explosions and fires. As they are basically only intended to be emergecy power supplies I plan to charge them outside, well away from the house. So it would be great to hear that your powerbank has had plenty of use, and no fires. Cheers mate.
Hi. thanks for joining my Patreon page. Yes I occasionally use the powerbank in my trips. it still works fine. the 6S BMS I use has the overcharge protection voltage at 4.25V, I hope yours doesn't have a higher voltage, because it's not good to fully charge the cells at a higher voltage. But I would change 2 things about it, the charging plug is rated at 0.5A and it gets hot when I charge it with 2A. you need a 2-3A plug. And I want to add another way to charge it. with a USB-C fast charge trigger module + a CC/CV step up converter to 25.2V, to fast charge the powerbank with a USB-C charger. it's more common than a 25.2V charger. Also I suggest you test all the cells. if you cant test them individually, you can use a BMS to charge and discharge them and you can connect a 6S battery balance/tester, to monitor the cells. if one cell is bad, you cannot use the entire battery pack. and test if the cells get hot while you charge and discharge them.
I like the idea of using the junction box. LM2596 don't seem like a particularly efficient regulator. Any time you see a diode on the board, it can't be that efficient. A design that uses battery holders would be easier than soldering cells together. Why did you work on the batteries while they were fully charged?
I made one with three 25w fast charge output but i use 1s18p so i need 6 tp4056 in parallel and a usbc to handle the 30w fast charge i will make a video about it later
I also made a powerbank but with 6 zells and i used a board that can handle all cool features such as QC 2.0/3.0 and usb type c in/out (check it out its IP5328P board and also watch great scotts video about it: ruclips.net/video/yEbbhTw0kno/видео.html)
@@typhonhunter I have a ready made one from local recycle center with blown battery It also use the ip5328 chip I have replace the battery and it work fine. It is the best power bank because even my diy one can't trigger my zenfone4 fast charge but ip5328 does My diy one use tps61088
Hey, awesome project ! Would it be possible for you to list the links where you bought the parts in the description? I'm especially interested in the battery source. Thank you !
I would have included a couple of small holes to allow airflow for cooling and for any expelled gases from the lithium cells during the charging process.
Yes, perforations on the two ends where the connectors are and the switch would allow for some air flow though that enclosure; the fins on the heat sinks do a better job of heat removal when there is some air flow. Another change I would make is to use a three amp circuit breaker rather than that fuse. But if it is going to be a fuse maybe the automotive style mini fuses might fit nicely on a fuse holder on that enclosure wall; that would allow easier fuse replacement should it ever blow.
Steve Tobias - maybe good, maybe not, to add a temperature indicator. Just like another comment that said to add a cooling fan, the dilemma occurs when this device is disconnected from wall power and operating as a battery - the mobile device that is running on the “backup battery” will not want any power drained unnecessarily. The temperature indicator would consume power when this device’s full power will be in demand elsewhere. It would certainly be useful while the device is being powered off of wall power. But I would still just leave it out, just like I wouldn’t add a fan. And thermal cutoff devices that can’t be reset are probably not so good an idea (same as a fuse, must be replaced).
@@stevebabiak6997 not if it was powered after the switch. This at it draws a small amount of power only during use. Also there are self resetting thermal cutoff components that don't need replacing.
If you add an another DC socket directly to the 6s BMS it gives the 25v o/p so you can use for any other experiments just like i did but in my case i used a 3s BMS from old laptop battery. 😊👍 Nice Power bomb Oops Power Bank. 😄
Hello Sorin, this is some great content. I know very little about electronics, but your video got me excited to try and make this powerbank. Could you help me with some additional information? What wire sizes do I need to buy for this project? An adjacent question would be: how do you know what size is best for each case scenario? (maybe the response to this one would be a good idea for another video). Thank you.
Hi. The wire thickness depends on the type of current used (AC or DC), also the length of the wire is important. for my projects with high current (DC) I try to use wires as short as possible. with 3A a 0.8mm2 wire will heat up over time, so I use 1mm2 wires. 1.5mm2 wires for max 5A. check this link for more info and an online calculator for wires: www.powerstream.com/Wire_Size.htm
Hi I have a 2 Flat batteries of 5000mah each from a thin & light laptop The output voltage from both battries are 3.5-4.7 v respectivilly & the total output when both are connected to the inbuilt circuit board is also the same. I want 8v-12v as the effective output Which circuit board should i use
hi. it depends on what current your load needs. you need a 2S BMS protection board with balance and a step up converter. the most commonly used is the XL6009 boost converter. but you may need a more powerful module.
hi. yes, it's a bit higher at 0.6C, that's because I didn't expect the charger to actually deliver 2A. I thought it will deliver around 1.8A. but that's not a problem, because the cells are new. a charging rate of 0.6C is still safe, the cells only warm up a bit, that's normal. when you stress older/used lithium cells, that's when you need to be extra careful.
Sorin how come the 18650 batteries with nipple is so cheap but without ..my gosh...can I use a hot glue gun to attach positive and negative wire on flat top 18650 or no???love that fat cat...think the glue will melt ?any recommendations???
hi. probably the coil is buzzing. you can try to desolder the coil and if you have access try to tighten the windings of the coil and then solder it back.

And thermal cutoff devices that can’t be reset are probably not so good an idea (same as a fuse, must be replaced).
@@stevebabiak6997 not if it was powered after the switch. This at it draws a small amount of power only during use. Also there are self resetting thermal cutoff components that don't need replacing.
Looks great despite putting several boards to make this supply
I enjoy your humour, it's like ELECTROBOOM's channel humour. I'm about to subscribe here. We all want to be your friend!
If you add an another DC socket directly to the 6s BMS it gives the 25v o/p so you can use for any other experiments just like i did but in my case i used a 3s BMS from old laptop battery. 😊👍
Nice Power bomb Oops Power Bank. 😄
Lol.,good idea...thansk haha
Yes ! Perfect, But Same(input) port can be used as output too! As it is not bound by any diode!
What a power bank it is!
Hello Sorin, this is some great content. I know very little about electronics, but your video got me excited to try and make this powerbank. Could you help me with some additional information? What wire sizes do I need to buy for this project? An adjacent question would be: how do you know what size is best for each case scenario? (maybe the response to this one would be a good idea for another video). Thank you.
Hi. The wire thickness depends on the type of current used (AC or DC), also the length of the wire is important. for my projects with high current (DC) I try to use wires as short as possible.
with 3A a 0.8mm2 wire will heat up over time, so I use 1mm2 wires. 1.5mm2 wires for max 5A.
check this link for more info and an online calculator for wires: www.powerstream.com/Wire_Size.htm
@@Sorin_DIY Thank you for the information and the link, I really appreciate it.
Wow nice Powerbank
Gentle man Sorin
Thankfully all his video is real, not FAKE.
Nice power bank and instructions !
I have a couple of NP-L7S batteries lying around without a charger. Can i use this circuitry to charge them ?
you need 6 lithium cells if you want to use the 6S BMS board from my video.
@@Sorin_DIY I have the complete battery NP-L7S.

Could you please help me building a charger for this ?
I would like to see you build on that has pps protocol included
I'm your friend and your young brother 00:35
Love from India🇮🇳🇮🇳🇮🇳
Thanks for giving me your RUclips 💜❤💜❤heart
Nice video.
Really enjoyed watching it.
Have you ever used a mobile phone charger as a variable power supply?
thanks. not yet.

In QC 3.0 you can ask for output changes with 200 mv steps.
I was thinking of using my old 18 w charger as modem UPS power supply
Hi
I have a 2 Flat batteries of 5000mah each from a thin & light laptop
The output voltage from both battries are 3.5-4.7 v respectivilly & the total output when both are connected to the inbuilt circuit board is also the same.
I want 8v-12v as the effective output
Which circuit board should i use
hi. it depends on what current your load needs. you need a 2S BMS protection board with balance and a step up converter. the most commonly used is the XL6009 boost converter. but you may need a more powerful module.
you should have left the fuse also open in the middle to make it more eipic and what if there was a tiny piny fan to Ventilate. overall Awsome
I've missed you man
cool project mate
Extraordinary
It looks like a bomb with time setting...
Сразу видно наш человек, синяя изолента это по нашему. Нафиг этот каптоновый скотч, если есть синяя изолента.👍👍👍👍👍
Congrats for your videos! You should make more DIY videos!
Great project. The charging rate is not too high thou? ncr18650b pdf shows recommended max rate of 0.5C
hi. yes, it's a bit higher at 0.6C, that's because I didn't expect the charger to actually deliver 2A. I thought it will deliver around 1.8A. but that's not a problem, because the cells are new. a charging rate of 0.6C is still safe, the cells only warm up a bit, that's normal. when you stress older/used lithium cells, that's when you need to be extra careful.
Sorin how come the 18650 batteries with nipple is so cheap but without ..my gosh...can I use a hot glue gun to attach positive and negative wire on flat top 18650 or no???love that fat cat...think the glue will melt ?any recommendations???
Good for speed charge
Kester brand solder works good on nickel. Rosin core.
My lm2596 is making sound when getting hot and output current of 5.33v,1.85A, any solutions
hi. probably the coil is buzzing. you can try to desolder the coil and if you have access try to tighten the windings of the coil and then solder it back.
@@Sorin_DIY I have buyed the same module that you have used in the video.
