All Right Video Time! Today we are going to talk about 48 Volt Lithium Iron phosphate Battery Systems this right here 74 amp power 48 volt right? 16s Battery system right? I Made a video where I showed you how to install this into the wall like this but people have been asking what about if you want to install this outside, how do you do it and today I'm going to tackle that project. I'm going to show you what you need to get so you can install this inside of a weatherproof box Electrical box. This is everything that you will need. You will need the box right? I will put a link onto Amazon where I bought this.

Then you will need your 16 cells LED 60 These are cells that are very very good quality. They put out a lot of power right and they're very very affordable at Jack 35.com I'll put that link to that one also and then you will need the 48 Volt bus bar kit. This is a big PCB bus bar system that I design so that it's very very easy for first timers to build a battery system sort of like this now taking out all the guesswork. Everything is labeled.

It's got the connectors in here so you can put the BMS all this other stuff so you will need that. Then you will need the 48 volt. uh, compression kit right? and that comes with all those screws and stuff. After that it's just a few more little things like screws and get Hardware But that's it.

This is basically what you need Now let's put that into the wall. Let's start assembling this battery system inside that box. Step one. Screw the box into the wall, right? Of course.

it goes without saying make sure you hit studs or make sure you have a backer like this. You're going to put a bunch of heavy batteries inside this box so this got to be properly secure, right? Good. All right. This next piece here goes in the back.

All right. So this is how the inside of the Box looks like. Now it's got two screws in every corner there. It's got this semi-flat surface there so that we can put our batteries in there.

Okay, next we're gonna drill some holes on the top of this box here. And here's the idea. This is a compression plate. The idea is that we're going to compress the batteries up against this, the top, uh, side of this box, right? and we're gonna use these threaded rods.

So these go through here and so we need to make some holes at the top. So in order to make sure we put those holes in the right spot, well, we have this as our guide. What we're gonna do is we're gonna put it over here, mark it, then drill it, and then uh, we're gonna use these rib nuts. And the idea behind this is that even though we're going to make a hole on the top of this box, well once we set these in there, the box is still going to remain weather tight because these are sealed from the top.

So I don't know if it actually gonna work. We're going to try it out. All right. So I just installed these and it didn't quite work the way that I was trying to do it.

It worked more the way that I originally envisioned I Thought I was gonna do it like this because I thought those had a hole that passed through. but once I realized that they didn't then I thought okay, we'll just put him backwards and then we'll stick this thing up here. It doesn't matter is the top of the cabinet. It's like nobody needs it up here.

it'll be water, uh tight. it'll be fine, but it didn't work. It was too much trouble to try to use the tool to go in there so it was easier to do it from the from the top you know, uh, to the bottom right? And so what I ended up having to do is just drilling the tips of those and then just passing the rod all the way through. So now in order to seal this, all we have to do is just cut this once we finalize and uh, finish, uh, strapping the batteries in here.

Then we'll cut this flush and then we could put a dab of uh, silicone in here right? and then that way the water doesn't go in there and doesn't go inside of the box. So now let's uh, put the the cells in here and strap them up. All right. So now we're gonna start installing the cells.

But how do you put them in there? Well, just follow instructions of this bus bar right? So positive and then negative right? So those are actually backwards, right? So we have to put the positive towards the inside and you start with the bottom ones and then you work your way up to the top. So here we go there. We go. Positive on this side, Negative on that, and now you chose this alternate positive here.

neg. the next one is going to be negative here and then positive and then negative and positive and negative that way all the way to the top. Thank you. Okay, next we're gonna install these.

These are like little bus bars and again, you follow the instructions of the main board. You see those right there, so you just follow those, put them in there, and then lasting. You put the board on top, put the washers, and then put the nuts, and then you tighten. You don't tighten it, don't over tighten it because we're still going to move this whole thing up.

Foreign. The next step is going to be a bit sketchy. What we have to do is basically lift up the entire pack and then tighten the bolts on the bottom right and so I'm going to use that piece of wood right there and I'm gonna wet itch it and then push it up and then tighten the things up. Okay, Next what we have to do is uh, put a screw or a screws down there so that we could attach to this whole pack to the wall right on the bottom there.

Uh, self tappers would work best. If not, you're going to need a long um drill bit so you can drill right through the metal there and then you can go all the way down to the wall. Next, we're gonna install a very minimalistic BMS in here. Of course you have the options here to do whatever.

BMS from this small one the best basic one to all the way to like a full-fledged BMS But today all we're going to do is we're gonna install a couple of these battery go Bg-8s All right, let's talk about BMS This one has these little terminals in here that allows you to very easily install your BMS leads in here right? You can put any BMS that will handle 16 cells. Uh, and that it works with lithium and phosphate right? and it could be fully fledged. You know, with all kinds of bells and whistles in there with screens and all this other stuff. Or you could use some very basic like we're doing here.

This is just two bat goes balancers right? These little devices here. all they do is just monitor your cell voltages and then you can come in here and tell it to balance if they're falling and drifting apart right? Uh, they? they you can set them up with like little arms so after they reach like a certain voltage or whatever they'll start beeping. And of course since they're inside here, maybe you won't hear them. but you know? definitely.

These batteries are brand new. They're all very alike so you could get away with something as small as this. These are very safe. Uh, they don't catch fire right when they fail.

they they just, you know they don't fail the same way that the ones in the Tesla will do right. So so yeah, you could. You could probably do this if you wanted to save some money or whatever. or you can just go and get like a full-on full fledge BMS if you wanted to.

But whether you go basic or you go full on, this will make it really easy for you to do it because it's all marked in here. It even has all these uh, this diagram here so you'd be able to see exactly which pin is, goes, where, and then uh with these little connectors here like it's super easy to connect I Didn't even have to fiddle that much with it right? and so this keeps it clean and super easy to install your BMS whichever BMS you decide to go with. Okay, last thing to do is to cut the uh, all thread from the top and then we're done All right. So there it is.

This is a battery encased in this, uh, watertight electrical enclosure. You can install this inside. You can install this outside. The only thing that you have left to do is install this little cover that goes on the bottom here.

but of course this is a blank plate. you have to drill your hole so you can put your conduit right and then you can put the connection in there and stuff and then you install it. Um, so the question is, why would you want to do this Instead of like, maybe just buying one of those? This is a 48 volt battery. It's already Plug and Play You can just buy it right.

And the reason is because you could do this way cheaper. You know that this is like sixteen hundred dollars or something like that. for 5.2 kilowatt hours, this is less a little bit less at 74 amp hours. This is a just shy of four kilowatt hours, but you can get these cells way cheaper right now.

Currently, if you buy 16 cells to make a 48 volt system like this, these cells are at 30 to sell. So that's about 480 dollars worth of the battery, right? Of course. Yes! Then you have the case and then you have the fancy BMS and then the bus bars and then all this other Hardware right? Well yeah, the case is about a hundred dollars in Amazon The fancy BMX is about a hundred dollars, right? So you're like at 600. this is like another 50 and then like 50.

you're somewhere around 700 which is around half price which you would pay for this. So the savings are considerable. And you know, uh, every time I do these videos it's always like, yeah, but it's you know, Nmc chemistry. It's the batteries won't last this long.

It's not a safe here for the first time. This is the same stuff. This is the same chemistry that's in there, right? And these are brand new cells. These are very high quality Japanese cells not the Chinese stuff that it's in there.

Uh yeah. this is really high quality stuff. same lifespan, the same safety margins. Uh, and you can do it for half the price.

So if you're in saving money and you're not afraid to DIY a bit, you know, get some pliers and get screwdriver and some wrenches and stuff. and you know, drill a few holes like we did here. This is an easy, really easy way to save a lot of money by building, uh, your own battery system, right? How much? Well, about half this is very, very compelling. So I'm gonna put a code on the description of this video so that you can, uh, get that special pricing for these cells.

Uh, 30 30 a cell, right? So then when you buy 16, be like about 480 dollars. All right. And with that I Want to thank you for watching this video and we'll see you in the next one. Bye! Okay here's how you order.

uh, these cells at the special pricing. You go to Jack35.com Then you go. Oh look at that price drop right at the thing here. So you come here.

and then the drop down menu shows you one cell for forty one dollars and then one box of six cells. And then you go on to the third option here. 16 cells for 48 dollars I mean 48 volts? And then that brings you to 479 dollars. You do the math, divide that by 16.

you come down to just a tiny little less than thirty dollars a cell. So that's how you get a special deal. And uh, then you can build your own power watches like we did in this video. All right.

See you guys on the next video bye.
