Thank you guys! Time to talk about batteries. And in this particular time, we're going to be talking about compressor plates. These right here are the Lev 60, Dash F batteries, right? They can about 74 amp hours. They can do about close to 200 amps continuous and 600 amps burst.

Uh, up for up to 10 seconds, right? So these, uh, there's very little info on these. We haven't found a spec sheet for these yet, so we don't know uh, much about them, right? We know their lithium are in phosphate and we know those specs performance specs right? That's it. Uh, we also know that these came in BMW cars uh, the I3 maybe and the I7 I think so among others have these under the hood, well in a separate compartment, right? But these are the 12 volt battery that runs the 12 volt stuff for the car, right? And the videos that I've seen of them. Uh, they show them being compressed in a small box that makes them look just like a typical 12 volt battery, right? but much lighter and much more capable because they have lithium phosphate cells inside.

So what we've decided to do is make compression plates for these cells. Uh, so that people can compress them when they buy them and they're getting use them in their application. Four of these will make 12 volts. Eight of these like this will make 24 volts and of course you double this up.

You put another row over there on the other side and that will make 48 volts. And so those, uh, we anticipate those are going to be the most popular use cases for these batteries. These are Lithium phosphate. They're long lasting, They're very, very powerful, and so those are the most typical standards, right? And so that's why we're making these.

So today, I'm going to show you how to put this together this compression plate kit right here on eight of these for a 24 volt uh battery, but at the same will apply for the other ones. This size of plate will work the same for a 12 volt or a 24, but for the 48 of course will have to be double the length of this and we don't have those yet. They're still they're coming from the uh, you know, the laser shop or whatever that makes them. And then we'll I'll show a separate video on how to make that one in there.

So let's start with this build. It's Very. it's going to be very, very easy. Okay, so first things you have to do is you have to align your cells like this: Positive, negative, positive, Negative Positive Negative Positive Negative right? So going back and forth, Uh, unless you're doing some kind of other, maybe you're doing an eight cell twelve volt battery, Then you would have two positives here and maybe two negatives here.

And then you're gonna go down like that, right? So two in parallel. Of course, These combinations are endless. You could do. These are like Legos You can do all kinds of things, but if you're just going to build a regular 24 volt uh, a battery right now then all of these eight cells will have to be in series so you'll have to go.

You know, positive, negative kind of thing. Then the next thing is because these are I tested the the, the the the case right? This is an aluminum case that it's out here. It's not positive or negative, it's kind of in between. but it is electrically charged.

Very very weak weak amount and so because of that then you got to make sure that they're the case are not touching to each other because I think they will over or they will discharge the cell eventually or faster than it should, right? It will create leakage and stuff and so for that purpose then we have to isolate them from each other. And yeah, they have this uh you know, thin plastic shrink wrap here that will do the job. It definitely does the job. but if you're gonna put these in a harsh environment uh, like an automobile for example, for like an RV or something 24 volt is uh, perfect for that case use case then you might want to use another barrier between them so that these will not chafe and they will not touch because you might see a problem later down the line if you have these in a application where there's a lot of vibrations or there's a lot of heat temperature ranges going up and down, you know there's things that might break down this thin membrane right here.

I Think this is PVC membrane right? So what I suggest you using is something like this. This is uh, fish paper I think they call it and I don't know the qualities of this paper I Don't know if this is the best material to use, but it is very commonly used on battery applications. battery pack applications. These a lot of batteries are wrapped in this.

A lot of batteries are used to isolate things within the battery and uh, and so that's why I picked that today to do it right. This is very, very cheap. You can find it a lot of places. We'll put a link in the description of this video so you can find it.

Another material that is used is just regular Fr4 right? Which is this, uh, fiberglass board that is used to make, well, Pcbs, right? and so you could make this exact same shape in there I Guess I'll make a file and I'll share it publicly so that you can do that. Of course this will cost more than the paper, but it probably is. maybe a better our choice. Now it will be thicker and so we'll add more length to your battery in here and that's a very thing to keep in mind right? But uh, today we're going to use this fish paper.

You have to put it between every single cell here to isolate them from each other. I've done this these already and then I have two more that will do the sides here the very ends. Next, what you'll have to do is then install the bus bars here. And these buses I mean this bus bars the compression plates.

These are just about eighth of an inch steel plates that are bent on the bottom like that, right? And that's so that they could use well. Two things so that they could be really sturdy. By adding a bent to a plate like this, it adds uh, strength. I Think it about doubles the strength, the rigidity this way, right? And so what happens is that it becomes really hard to bend this now, right? Which is what you need.

You need a really stiff plate to push these like that, but it also adds as a flange right here so that you can, uh, secure your battery into another surface. For example, right, if you're gonna Mount whatever, you're gonna Mount this, maybe into an electrical box or a case or something like that, then you could use these holes that are on the bottom of this plate to to attach them there right? Um, now. Also, there's a downside to this because this adds a little bit of uh, size to the battery, right? And so maybe if you have dimensional constraints like, uh, a lot of the times do, then this might not work. Maybe I'll just make a plate that doesn't have this for the future.

If you need that, post it in the comments and if there's enough interest there, I'll make another pleat like that, right? But for this one, we do both sides. We put one on this side and one on that side. Next, what you will need is to use uh, all thread and the kit will come with these. It's going to be oversized because depending on what material you use here is going to determine the over the overall length of your battery pack.

right? So there these are going to be about 24 inches for the 24 volt and about 1 12 inches for the Uh for the 12 volt kit. So you put this in here and then you put the nut right in there and then you do all four right. So the next thing to do is just to tighten the uh the nuts here. Right now, there's no spec sheet for these like I said.

so we don't know what kind of compression they need. We don't know if it's two pounds or ten pounds or is 20 pounds right? So right now we're just gonna compress them. Uh, so that they're secure and they don't move around. So you can move this battery pack as a single unit and they don't slide or anything like that, right? And so okay.

Last, we will have to put the bus bars here right and so just put those in there most positive and then like that. Now we're gonna have these bus bars available in Copper and aluminum depending on how much power you want out of there. And of course you could also get the full board that is going to be able to go in here and then this makes it really easy for you to do the wiring for the BMS right? Uh, and so you have choices here and how you want to finish this battery. You could just use regular bus bars like this.

or you could use that bus bar plate that goes. Just kind of simplifies everything, but the compression plates will work the same whichever way you decide to go for busting these batteries here. right? So there you go. This is very, very simple way of compressing these cells.

Now it's a single battery that you can attach it to whatever surface you got on the bottom. You could potentially attach this to the wall too, right? You just use big enough screws on these plates right here. There's four holes in here. Uh, you could definitely drill these bigger if you want to put bigger uh uh.

screws to put it in the wall, but you definitely could. Could hold this into the wall. these are very strong and then these are. You also have a third hole in here so you can use another.

You know, three, um, all thread bolts going to connect these if uh, again, if you're going to install these in a very, uh, harsh environment where there's a lot of vibrations or something like that and you need that extra Hardware to secure these uh, effectively. right? All right, So there you go. Thank you for watching this video. We'll see you guys on the next one.

The links to all of these components to make this battery pack are going to be in the description of this video. All right, we'll see you guys the next one. Bye foreign, foreign. You could build these here on the wall right so that you don't have to carry the big heavy battery pack and then you just assemble it in here and then uh, at the end, you just cut these because these are long, right? They're gonna come long because depending on what you're using between here, it's gonna affect the the overall.

Lane But you could also just build this on the bench and then just bring it up here and screw it to the wall. but I Was able to do this by myself. They're not too heavy so you could do it both ways. Also, by the way, this is a 224 volt modules if you want to use these in series and uh, use them as a 48 you would have to get the positive from one and then the negative from the other one and then just tie in the positive to the negative between the two packs, right? Obviously a much better way would be to take this one and flip it around and then you end up with the positive and the negative here and then you just Bridge the top over here, right? And that is exactly what the 48 volt uh version of this this bus bars is.

There's just two of these Set Side like that and they're just and so then you'll get positive and negative right here here. and then you get one single connector uh for the BMS here. but of course you could use these uh two of these to make 48. Uh, you could parallel these ones to make double the capacity, right? On a 24 volt system, you could use four of the 12 volts also in setup in series to do 48 or in series two of them to do 24.

this are there's many ways you can go about the building battery banks with these cells. These are raw cells right? So I'm just making uh, compression plates and then bus bars so that to make it easier for people to use them. Uh and so uh, hopefully this product this this compression plates uh serves that purpose because you are able to compress them and install them into the wall or install them in a box metal enclosure. You could put this inside of a metal enclosure by the way.

Uh, which is a much better. having stuff that's exposed like this is not the best way to do it. and I know a lot of the DIY Community has been doing this for a long time and I guess if you can keep stuff from falling in there and shorten it out I guess you can get away with it. but I always like to put stuff in metal boxes because then that's kind of foolproof.

If you have some kid or a dog that's coming here and pee on this thing or some kid touching bus bars or whatever like, they're not going to get electrocuted that sort of stuff right? And so I think a lot of the codes also require uh, depending on where you're around the world, but here in the states I think a lot of the codes require any electrical stuff to be in a enclosure. metal enclosure be sealed so that there's nothing exposed there, right? So keep that in mind. Uh, you will have to do some homework and you know, search what your local codes are about. Man, that thing is loud.

Uh, but there you go. This is a just an example of how you would put one of these either in a house or an RV because it's 24 volts. Perfect for RV right? Okay, thank you for watching this video. We'll see you guys on the next one.

Bye thank you.
