Hi folks today I’m going to show you how to build yourself in monster power banks. In fact, we are going to use recycle a battery that came from an electric scooter but following my process can recycle and reuse batteries that came from power tools or battery from Hoverboard three from an E bike and so on basically what we need is a huge battery and the voltage I suggested between 12 and 42 V in this way we can buy so cheap battery packs online and we can just use a step down DC circuit boards which basically let us control the voltage to the output in this case normal USB port needs 5 V but for safety reason, I decided to install a circuitboard that came from a real power back. This can be so cheap to find online. I’m talking about two dollars each and this little circuit board. Let us be very sure that everything is safe because the circuit boards works taking 3.7 V as input and step them up to five goals but this process is necessary to be sure that we don’t have electric spikes and everything doesn’t produce voltage spikes that can destroy the phone
I put your links as well here about the 3-D file you can print by your own. It’s very simple box with the handle that let us close all the battery in the circuit board inside but this depends on you on which circuit board you’re going to use so check with mentioned before printing
I’m so excited because this project is very simple to replicate and I’m pretty sure you can build yourself at home this power bank that has so many milliamp hours and let us have so many watts to charge the phone
But for the math calculation, I let you do for fun and find the numbers of charge. I can use my phone with this huge battery consider they build such a huge power bank just because I am docs restricted with Waze. I mean I will use this power bank, even my tent, and the way doesn’t scare me at all.
Double check all the connections and make them very tight. Otherwise it will get hot and you can raise the burn everything we are talking about so many watts so make a connection properly.
Nice project! I love 3d printing stuff for real world use!
Always a good morning to wake up to coffee & Rulof. Great project, looks like it would have heaps of capacity. Love the new haircut but you look great without too 👍
How do you load the powerbank itself ?
I'm pretty sure you could have found the proper circuitry to do this powerbank instead of the the boards buck+usb
Great videos every time much love from Tennessee
everything is cool still small missed part how the power bank will be recharged? while its 36v pack
production value is really good , is very engaging, i dont get why your video dont get millions of view like the use to :(
Love this with the voltage and amps available in that battery u could totally add a wall plug and inverter for ac appliances
sounds great! happy to give inspiration!
should implement PD charging instead so it supports laptops and fast charging for phones
Love that we get the talking rulof again.
$130 for the battery alone.
Just buy a dirty cheap used scooter
@@Ricciolo-oj1nc Dirty cheap used scooter with GOOD battery below 25USD? Tell me where, I will buy it.
Just search better from Chinese dealers!
Just think about how much juice you have to charge your phone tho
@@carbonEX-2023fake sells. check video's.
ppl pound sand in 18650 instead of a battery
I am also wondering how you charge the powerbank, you cant do this through the output port.
no! you can see i pug in also the original plug! it needs 42 volt transformer. 10$
You can use bidirectional usb-c pd kit to maximize the performance.
Very nice project, I would put a 12v outlet instead, so you could use other appliances with it... congrats 😅
Add a small 36v inverter and you could have a 240v power bank ad well. 🎉
I wonder if it can be made into a wireless charger?
How will you charge the power bank??
Do you still have the old usb ports in it that you can use for less delicate equipment like for lighting etc!?
That’s a great idea! I decided to not connect them.. I just need one port.. but great idea
Rulof, where are your older videos?
Great video! Keep it up 👍
Be careful with that buck/boost board. The capacitors and chips are only rated for 35V. When the pack is fully charged, it will be at 42V.
What happens to the other channel??
heheh the last video there explain everytging!
You could've used buck converter to get direct 5v...🙁
Would be interesting, if you can jump start your car with it.
This is AWESOME!!! I'm jealous!!! - BUT, you never said ANYTHING about how to charge the batteries back up again.....
ALSO, did you keep the original 2 USB ports still connected? AND Why didn't you leave those USB-C ports open? You could charge your phone with a usb-c to usb-c cable instead of a converter cable AND you could probably charge more than one device at a time.... but I know you have your reasons.
I am very interested in how you charge the bank back up the most..... you can get A LOT of charges out of that bank, but if it's just a one time use then that is quite wasteful..... If you can charge it up please tell us how because I really need a power bank and I would like to make it solar charging.... but I know nothing about it. Maybe you could make a video about that? :)
This would be fantastic for me.
I have spent the past two years living in a tent in Slab City in California and i use power banks to keep my phone charged and run fans to stay cool in the summer.
If he connected the board from the old bank he disassembled right he could plug a charger into it and start charging the bank but it'd be very slow.
I charge my power banks off solar panels designed for charging usb devices. Something like this i could rig up a pure sine inverter and use it to power my laptop. Haven't been able to run it in years.
He mentioned there were two cables: one for the power out and one for the charger.
If he left the charge cable connected and the port exposed then he charges it by plugging in the original charger.
You can see the charge port at 7:42.
If you’re buying a battery it should tell you which charger to buy. If you’re building one then you need a CC/CV charger and you’ll need to know how many cells are in series to get the CV and what is a safe charge current given the number of cells in parallel for the CC.
I recently built a 7s4p pack, max cell voltage is 4.2 so 7*4.2=29.4V. I used Samsung 35E cells that have a safe charge current of 1A each, 4*1A =4A. So I bought a 4A 29.4V li-ion (CC/CV) charger - worked a treat!

Why does Someone as smart as you live in a tent 😳
Unless it’s your way to off grid live type of thing. Wish I could do that. I know a couple that set up a trailer in middle of nowhere with solar panels, seems so peaceful yet actually affordable.
@@carsonhunt4642 I ended up homeless in 2020. Since I'm on disability i don't have a job. So i was living out of my car for a while before it hit me that i had a rare kind of freedom and I could pretty much go anywhere I wanted.
But i couldn't afford to keep up the insurance costs on my car and my plates and registration were soon out of date which ment that getting caught driving would land me in jail.
So i didn't have many options and Slab City was the one place i onew for certain that i could go and just build up a life from the ground up.
So that's what I've done.
Before you go thinking it's some kind of beautiful, don't daydream too hard. It's 115 in the summer, sometimes more. It's filled with anarchist types and it's near an active military base so if your neighbors aren't shooting at all hours of the night, the army is.
There's no utilities of any kind. No natural gas, no electricity, no running water. So don't expect to have a shower frequently or have frozen food.
Then you got packs of wild dogs, packs of coyotes, scorpions, tarantulas, camel spiders, and skin walkers (aka meth junkies).
All that aside there's positives. For one thing you can live as free as you want. Plop a trailer down in some deserted spot and there you go. Or if you can the skills, equipment, and stuff to do it- build yourself a shack somewhere.
As for why I'm here it's pretty much because I don't have anywhere else to go. Plus there's a side of me that kinda likes this life. Like living in a post apocalyptic wasteland.
Idea is nice but not in this cost. Normal 5V 1.5A need 3A from cell at 4.35V. Cheap dc-dc step-down is not enough
Just i hope that your batterie has a BMS integrated !
of course! needs only a 42 volt transformer ;)
add pd an 230/110V
❤👍
Oh f.... You load five watt xD you need a quick charge Board, the Board can more voltage work. step down self and you have many more current! And you need less space.

Btw battery is from a clone of Xiaomi
Great video as always Rulof, the soles of your big feet must be ticklish big fella.
Baller
too big and clunky also your soldering was bad i would practice get some better soldering equipment do some research. Just throwing in my two cents no hard feelings buddy just trying to help i hope you become a very successful youtuber
You're baaad at soldering...
