600,000mAh DIY Power Pack build

Hey, let's talk about batteries. One of the questions that keeps coming up from time to time is why there is no suitcase battery. Different versions of that keep showing up in all my videos, but it's essentially why there's no small battery. in all the size of a suitcase and traditionally the reason it hasn't existed is because those batteries are very expensive, the batteries are really big and heavy and expensive, yeah, those are two main reasons, so essentially you can't fit a battery large enough to be useful in the space of a suitcase, but in recent years, in the last decade, battery technology has progressively improved, so now, in 2019, the question is why not exists.

Can we

build

something? I would say the challenge is

build

ing that battery and seeing how useful we can make it. What are you saying? The first thing you have to choose is a case, so let's go to amazon.com. Well, here's one. This heart-shaped case from Amazonbasics is small. too small, the large one is too big, let's do the medium one next, you have to figure out how to put all the batteries together and luckily I've been working on that so just go to kit.com, first, then Jehu and then you. Go to this page here to see the small battery

pack

.

These are the 24 volt 7s battery modules so for this specific project we will need 14 of these and then it will need to be MSS. Next, we will need batteries. let's go easy on EB West for this particular project. I think VP c6 is a perfect cell that has energy density and

power

density at the same time, so you're going to have to get a case of these 200 of these cells to populate that case, so there we are. We'll need a few more pieces, but they'll be linked at the bottom of the description of this video. The first thing we need to do is assemble our 14 PCB battery module kits.

This is pretty simple, you basically have to solder a connector to the battery holders and a fuse to each of these plates. I have a separate video detailing how to do this and it is linked in the description as well. Next, take two of the modules that you just completed and place them next to each other with the connectors facing the same direction and then arrange them so that you need them to kind of mirror each other. What you're going to do is take these xt60 pigtails and solder them here until you finally end up with something like this, next take three. different modules and you are going to solder the xt60 connectors, the xc60 connectors go on the opposite side of the ribbon connector.

Alright this should look like this when you are done below the two BMS holes should be populated and for this too I have a separate dedicated video that guides you step by step on how to fill the BMS boards. So at this point, this is what you should have. You must have one, two, three, four, five, six, seven, eight, nine boards that are populated with the basic one. things being the ribbon connector, the battery holders and a fuse and then three boards that have all the basics plus the xt60 connector on the bottom of the board then you should have two that instead of the xt60 connector will have an XT 60 pigtail and then the two BMS boards.

Next, let's take a look at battery cells and what we should do with them. The eb west six vtc cells come in factory

pack

aging, they were designed for oem automotive use and for that reason they do not. They have wrappers, that means you have to wrap them, the process is not very difficult and it's not very expensive, then you take a carb like this, put it on the positive side and then slide on the pre-cut wrappers, you can get them in any clear color. like this one or in this case I'm using the green ones, the whole process takes about an hour to make the 200 cells, which you're done with, now you're ready to start populating your boards, here are some things to think about. make sure all your cells are at exactly the same voltage now if you take them right out of the box they came in and wrapped them here they will be about three point four three point five volts and they are all pretty close together so you don't have to do nothing you choose after the popular ones, but if you've played with them, charged and discharged them for testing or whatever, you need to make sure they're all the same voltage. when you put them on the board, once you do that, you have to pay attention to the polarity.

These boards are marked plus and minus, so the positives go up on this side and the negative goes out. Make sure all your cells are oriented. the right direction in the same direction and then you can start popping them, in this case one, two, three, four, five, six, seven, they all look with a positive on that side, the positives here, then you can complete them and complete them is Very simple. that's the reason you're going with this system because it's the easiest to populate with cells and that side is done, let's do the other side again.

I can't emphasize enough how important it is to make sure all cells are facing right. direction and in the same direction, these batteries produce a ton of energy and you are going to melt things if you don't burn yourself or ruin your boards, you know that at least, so you have to pay special attention when you do this and so, your The first board is ready, now you have to do the other 14. Okay, now they are all done. Now it's time to start assembling. The first step is to take eight of the base boards plus the two that have the xc60 flex cable.

This is the layout of the The first module will be two of the basic ones and then one with the pigtail and then one two three four of the basic ones and then the other one with the pigtail and then the other two of the basic ones so let's start putting together my first putt these two together, so in the first module you will take two of the 25 millimeter standoffs, place them on the top, then take the 40 millimeter one, one on the back and then one on the front right, and that one is on the top, bottom, here.

You're going to take one of these screws and then you're going to put it in there and then you're going to use them and then we're going to have to tighten all of those first module, second module, okay, so the second module is right on top, make sure the positive is with the positive so no. you shoot it if everything is fine everything should be the same there should be no sparks press those types I take this type the one with the pigtail the one with a pigtail next to the connector here I check if there will be sparks when doing this, once I see that there are no sparks , then you can plug it in, it's just a normal module, another normal module, all good, on the last one, what I'm going to do is put nuts. on the ones here on the right at the bottom here and at the top we're going to do woman to woman nylon standup and that's essentially what we're doing one two three four five six seven eight nine ten these are the thirds from each side and are pointing inwards.

Now to make the first side module we will start with a BMS and with two of the boards that have the xt60 connectors we start with the BMS. use two of these 25 millimeter standoffs, we're going to use two standoffs and two screws, there we're going to look at that, then we put the neck module on, use the 40 millimeter brackets, then we do the next module and then we'll do four nuts. there we go our module we are going to build the other module well for the second module again we start with the BMS and four of the 25 meters for the bottom then we take the basic one and install it like this here we go before stopping finally we do the last one that has the connector and we finish it with our mouths here we go well at this point your project should look like this ten modules here with the two with the pigtails here and then this side one you know with the two connectors and then this one with a connector on the right and then with screws at the bottom and then stand on the top.

Well, at this point let's talk about the tape. You will need a ribbon that is at least 50 inches long. We're going to put these guys three and five-eighths inches apart and then this one will be two and 1/8 and then this one will be about nine and a half and then the next ten will be about two and 1/8 apart then, but you'll leave a about 12 inches spacing for the last three and then again it will be 1 and 3/4 and then this will be about two and a quarter when crimping the connectors to the ribbon cable. It won't be difficult if you use the right tool, it's linked in the video description, so any leftovers you have you can cut off at this point and make sure when you cut them they are nice and clean so you don't stand a chance. know that they are shorted so this is how you installed this ring so start on this side go well this is essentially what you have to build 14 boards stacked on top of each other and then to the BMS units on the ends of Of course, you can't leave it in this rail because well, it doesn't fit in the case, so what you have to do is push this guy and put it here and then these to push them here and so all these.

Other cables are to plug that in to connect the electricity from here to here, well there are two of those and then these guys have additional cables here to then allow to have them there. Same thing is the easiest way I found to actually go all the like this, but I'm here, so that's going to

power

the next one that's going to power this one at this point, it's time to put it in our case, then we're going to take our side module, we're going to connect the ribbon cable and then We will secure it with two screws, then we will connect this cable, then we will install this module.

The tape will go over the back of the screw and then we'll need to install the holodeck sensor that I'm going to use. Ok, at this point you will have to drill some holes in the box or meter and the main terminal posts, then you need to connect everything following the wiring diagram found here. You can pause this box here or you can find that link to download the image in the description. Okay, after all these steps, you now have a 30 pound box with 2.2 kilowatt hours of battery fully protected by a BMS that will deliver a maximum of 100 amps at 24 volts, so what exactly does 2.2 mean? kilowatt hours?

How much energy is it exactly? equivalent to powering a 100 watt light bulb for 22 hours, yes that's old school, no one remembers these things in modern terms, it will charge your iPhone 270 times or your 13 inch MacBook thirty times, it will power an average refrigerator for one or two days. a 32-inch LED TV for more than 100 hours. As you can see, this is a very large and versatile battery for RV users. It can be used directly as a replacement in your 24 volt systems, but for most other things you will need to convert the battery from 24 volts. volts to other formats such as 120 volts AC or 220 volts AC using an inverter.

I have some link in the description so as a definitive test for this battery I invited a friend to help me so I'm here with my friend Ben Sullins from On the Tesla Nam --ax channel let's test if we can charge Tesla with this battery that we just made, so if you want to follow me on his channel Tesla Nam ik, follow the link here in the description, follow the link here. on the screen or in the description and then you can see if we actually managed to charge Tesla at this point, as always. I would like to thank you for watching this video and I want to invite you to watch the second part that Taken on the Tesla Nam --ax channel by clicking this link here.

Thanks once again, see you in the next video, so yeah, a battery.
