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!
sorry to be so offtopic but does anyone know of a tool to get back into an instagram account..? I stupidly forgot my login password. I would love any tips you can give me!
@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.
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!

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.
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.
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.
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%
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 !
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. 😄
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.
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 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.
