I Will Make the World's Largest Phone Battery (iOS & Android)

Jun 01, 2021
Imagine living with just one

battery

to charge your

phone

for a month and a half. It's a rainy day here in Cordar, so I've decided to tackle a project I've wanted to do for a long time. I want to build the

largest

portable power bank for my

phone

using an old lipo

battery

that I am going to smash, resolder and reuse for this battery project. I'm very excited, let's do this, why do we have such a big lipo battery? A few years ago we got these really big drones flying like red cameras and one drone needed three of these batteries to fly.

We ended up getting rid of that drone, but kept the batteries, so these guys sat on a shelf for literally years. The guy is broken, why one of these cells? In fact, you can see six cells in this bag. This cell here is broken. They produce gases and when not treated very well, can expand into their own container. That's why you have an old lipo. batteries and they are swollen right now this battery is mostly fine however this dead cell is preventing the rest of the cells from working normally we can't use this anymore right? What are you doing Sam?

More Interesting Facts About,

Yes, get out of me, no, this is the best. efficient way out the door this is an expensive battery I don't want to get rid of it so I'll try to reuse it by removing the dead cell and keeping the five good cells this is where things get a little dangerous If I puncture one of the battery packs too much, literally It could cause a chain reaction and could start to burn. We have done it before. Look at this. I feel like it doesn't need to be said, but I

will

. Say don't do this at home.

The only reason I'm doing this is because I've spent a couple of years studying batteries and how they work. I feel comfortable enough to be able to handle this. Let's do it. The fire extinguisher is correct. okay, I'm going to

make

my first incision in this lipo, this outer layer is hard, oh, it's metal, it's aluminum, okay, we're getting close to getting this right first, I'm just going to remove the bad cell, I'm going to cut all of them out. these cables, in fact. I'm going to do that right now. I don't need this balanced cable.

I should have known the timing of that joke better. I'm using the wrong cable cutter for this. That was the dumbest thing. Alright. The battery is fine. There was simply a short circuit. for a moment I short the battery and you have it in the camera I'm not proud of that battery it's okay the battery is okay the cables are hot I burned my finger I know better so hard apparently you don't I know better, apparently you're right, it's a lipo, remember the part where I said don't do this at home, I'm not kidding, this is the dead cell, you can actually see it dripping here.
I'll have to wash my hands afterwards. this is toxic this is dangerous now this surgery basically involves separating each of the cells from each other and this is where it gets a little hairy I didn't do it right yes I'm fine why did he do that that wasn't right that was scary oh Oh it was a quick glance, you see it made contact right here and more specifically the scissors shorted out, that's a little scary. I have to be very careful not to let that happen again. My hands are shaking. I'm fine. I'm going to walk away from this, oh it went well, lots of great pictures, this is like these little birds, you'll have to watch the video, oh, the battery got a little short?
I realized that my problem is that I keep shorting it with the scissors, so I'm going to put electrical tape over the contacts while I cut these things. Now I have five perfectly good cells that I could also

make

five separate power banks with, but that's no fun. I want to make the power bank bigger, so I'll put all these cells together in parallel as one giant battery. Imagine charging eight phones from zero to 100% every day for a week or a single phone for over a month. I taped them together with regular duct tape, each of these terminals

will

be soldered to this wire and each of those terminals will be soldered to that wire, which should be easy, so the cool thing that it allows you to do DIY battery builds like this is that you can buy these USB chargers really cheap online, so I bought several of them.
Each small circuit board has two USBs along with a micro USB for charging, so if I connect four of these circuit boards with two USB ports on each. I can charge up to eight phones at the same time a power bank this size charging eight phones that's unheard of okay cables my scissors now I have four cables to use let's solder these guys in fact I'm going to connect each one of these. small circuit boards together in parallel so that they all get the same voltage and current from the battery at the same time, the last one, the last one, then all the small circuit boards will be tattooed tomorrow, so now I need to model a 3D case of some way. which can hold both the battery and each of these four USB circuit boards so that they are all safe and secure this battery is very fragile it is very volatile and very venerable you are trying to be illiterate alliterate illiterate I honestly think the next part is probably The more challenging aspect for me because I don't have much experience in designing 3D models.
This is a little outside my experience in 3D modeling, but I think I can do it. This is already done and the case has also been made. Look at that magic. Pretty basic, it's just a box of planico said oh, just make it really big, we'll never use it or anything and I was like what do you mean we'll never use it? And I think their fear is that it's too crazy. so my mission suddenly became we have to make something we will use, we will use it, I miss it so much, I love the rain, it makes me want to drink some, try to wrap yourself in a blanket and touch some dark souls, I'm going to put a little apple cider in a pot and heat it up it's very bright but also gray whose truck I need to solder now all my USB stuff all good are you okay?
Yes, all good, all good. I accidentally shorted the battery with the soldering iron. Damn red, please tell me this isn't one of those videos where he just randomly sparks from time to time. Oh wow, I don't want you to blow up your face or burn down the studio. No, I trust myself. you want to do any of those things safety first you want to put your shirt in front of your mouth when soldering okay last last one this lights up we'll know it works ready it worked charging oh my gosh here it works it's actually working.
Yeah, that's really awesome, but I think you should put a warning in there too. Do you put a warning on these videos? Have you heard of those people who, like you, get thrown out of a plane and somehow survive a 10,000-foot drop? They're not authorities on skydiving despite being successful, you know, I feel like that's what we're at right now, man, he's right, I mean he did it, I'll be confident enough to do it, but I definitely have no authority on this, he's okay, wait, but This is actually the moment you succeeded, so congratulations. Technically, this is the battery powered by eight USB ports.
It's time to put a case on it and secure it in its final form. Look, that's really cool, man, it looks. like my shirt in the spirit of reusing things, I'm actually going to reuse the insta360 case and I should add some extra protection and cushioning to the battery so the chances of it getting punctured are much lower. A good job of high quality cardboard from insta360, so this is what I mean when I say liquid tape, it's basically electrical tape, but it's in liquid form, so the idea is to cover each piece of metal completely with this material, even if it's a little difficult to fit this correctly.
Now the phone will compress over time assuming I don't break this in the meantime and look at that, so now I have to find a way to make this all fit here. I thought about designing some screw holes, but screw that cyan acrylic. Wow, I'm using too much glue, you don't need much super glue, it's not like hot glue or epoxy or anything like that, where it actually has a physical volume, this stuff acts as a bonding agent between two surfaces, ah, gosh, my fingers. they're stuck together they're they're oh god no don't you dare you'll break my skin oh my god my finger is actually stuck together I can't I'm trying to break away okay there I was after all this.
Effort to create a battery that can power eight phones. Hey, does anyone need some power on their phones? Gently, okay, gently, ah, you know, hey, there's room for one more. We are currently charging six phones and can go for a run. We get to where you're going. it's good coming out
