Build Super Fast & High Capacity Power Banks (130W) - DIY Fast Charge 15000mAh Power Bank

* LINKS & 3D MODELS LINKED BELOW*
In this video, I'll show you how to build yourself a fast and high-capacity power bank at home! You can use some old 18650 cells, pair them with a few more components, print a case, and assemble it all together!

I have a kweld. It changed my life forever. I hope you'll be able to get one soon. You'll love it. Worth every penny.

[@Djambo57]

I was thinking about getting something smaller like that... I once borrowed a larger spot welder from a friend but it kept tripping my circuit breakers... The current spike was too high while turning it on. I also saw a bunch of battery powered welders online and I actually did use one of those before and it was quite good. They are around 50-60USD which is not bad

[@nixon275]

Amazing work dude, as always. 💪

[@duggrein409]

Great work

[@beachcow1650]

the thing blurred at 1:34 looks suspicious lol also this video was really good, and the end product was amazing!

[@Djambo57]

Haha, thanks! Looks suspicious indeed

[@gamereditor59ner22]

Ah sweet!!

[@Djambo57]

Thanks!

[@gamereditor59ner22]

@@Djambo57 You welcome!!

[@misterinfinity4076]

Why are you using different kind of cells? Is this safe?
I have almost all the parts laying around, except from the usb-c output//power delivery trigger boards. I've thought about building a 5s power bank for a while, but i am concerned about the quality of all this type-c boards. I've seen some horrors while browsing alliexpress, and i've even got some that completely disregard every protocol/handshake. are you confident enough to use them to charge phones and laptops?

[@Djambo57]

You should never use different cells! Looks like a forgot to mention that. I did use same ones but in some shots I had different ones just to show what I'll be using. I've used this modules for quite some time now and I didn't have any problems. They do have a bit of noise but they work, I'm not sure how I could test them better. I drained the whole power bank from a 100% to 0 in a single use multiple times and the modules did get a bit hot but other than that, everything went right

[@bosslite23]

You could do this cheaper using just the bms, battery charger and charging module and to monitor the charging a led voltage meter

[@Djambo57]

Yeah that would be the simpler way but I wanted to throw in some extras just for fun since I already had the parts

[@emiljanduka51]

if the cells are connected in series that means only 3000 mah

[@Djambo57]

yeah it's 3000mah, 63Wh, I said it's 15000 only in power bank terms since most of the power banks on the market use a single cell inside and the capacity is the first thing you see on the box.
