Hey there, you know what time it is time for Batteries Let's look at what we have in the bench today. All right Car Modules: This one right here comes from made in Poland these are Jaguar batteries. LG It's got those identifiers in there I've done some research on these and it looks to be a 3s module which is weird I know. which means it's gonna be really big too.

Like a lot of amperes. A lot of amp hours, right? So the cool thing about this, that it's sealed. you can. It's welded.

You see this. These are welded. and so the only thing that's exposed here are the two terminals. the plus and the minus here.

so that's pretty cool. These probably are safe. They're not going to catch fire when they they do. well.

they're encasing this uh thing. Hopefully they have, uh, some way of venting so that it doesn't blow up. so that's cool. There's no way that you can mess with these and damage them, right? The bad thing is that well, if one of these cells gets damaged, you can't re-fix it.

It's the whole module or nothing. But the other cool thing is that we also have the connectors. I Think we have a connector for everyone Module: We got a pallet of this one in today and we're getting another palette later today. So they're going to have about to almost 300 of these modules available.

And so what I've done is I charged it all the way through. Now we're going to discharge it up. Yeah, by the way I figure out the pin out here. Uh, there are mirror.

There are two kinds of these modules. I Guess they would mirror. So one is the the white connector, the other one is the black connector, but this one right here. The wide connector is the one that works.

Boom! Three cells. There should only be like four cables that are actually usable. The other ones are probably temperature sensors. so they're identified by this little thing, right? so you would be able to see what they are.

So according to this thing right now, they're sitting at 4.14 and I've had it this for like a week there. I charged it and then I let it sit just to see if this is always a good practice to do. it's just to charge it and then let a battery sit there and then if there's faulty then it's gonna lose some voltage. But if it's good then it's It's gonna stay right where it's at.

So let me connect this into an inverter. a 12 volt inverter and then we can see how much power we can get out. It's not going to be the full capacity, obviously because this is 3s and 3s is just a bit too low. It's 12.6 volts nominal, right? so there's definitely going to be some.

That's the problem with little man batteries. They don't make great 12 volt, right? 3s is too low. 4S is too high so it's somewhere in between. and that is the thing why we always never well so just or recommend using Lithium-ion or Lithium Cobal oxide or Nmc.

chemistry is a 3.7 volt chemistry there we usually don't recommend using if you need to use the entire capacity of the battery for audio applications. I Have learned that a lot of people are using it because they don't actually need the capacity. they're more need the power output. and I would probably guess that these batteries are very, very powerful.

The only problem is that they're going to be too low voltage for audio up here, so these probably are not going to work for for audio applications. although I might be proof of drunk I don't know. so maybe these are going to be great. If they have the energy density, high energy density, maybe a sum or above 200 watt hours per kilogram, then these are going to be great for electric car conversions because they have a high energy density right and the power dancing to also push quite a bit of amps and stuff.

Let's test it and let's see how much we can get with a 12 volt device. Uh, maybe I'll do a separate test where we actually try to get the actual capacity in here. All right. So we have the test set up here.

This is the battery. It's connected to this meter to a 12 volt inverter that is going to a heater, right? So uh, this uh is going to record that in there. and let's start this test. Here we go.

What are we? What are we seeing? 130 amps, 150 amps out of the 400 amps I Don't know at all what this battery is, so that's why I put 400 amp hours so we'll see at what point does this quit and then we'll know how much we use, right? We subtract it from 400. Okay, this following test here took forever. This is over two hours and so the phone ran out of battery. Uh, and then I couldn't really.

uh, export the video. So all I did here. What you're watching is you're looking at, um, still images, right? So every 10 minutes and so you could see that we started with 400 amp hours. We're at 297 right now and then somewhere around here the load quit.

Um, and you see there's only 3.25.3.6 amps. That's because the timer on the load quit. So then I restarted it and then here we are to use the different camera and here we are Here's the final number 204 out of total of 400. So about 200 amp hours you're able to remove using just a regular 12 volt uh inverter.

All right. After further investigation, this modules turn out to be 2.6 kilowatt hours or 236 amp hours. So, but just regular inverters. 12 volt inverters that you can buy off the shelf and stuff.

Nothing special that nothing. that's like high-end that you can adjust the voltage. If you can use 200 amp hours, that is equivalent to 84, which is not bad, right? That is exactly what you want to do. if you want this battery to last a long time so you can install this in the wall.

Install a regular 12 volt equipment and it'll use it up to it reaches around 80 percent or something like that. Probably because the last four percent is where the alarm starts going and you would probably drive your nuts. Uh, but here's the crazy thing. if you get Victron on the Vic trans, you can set the low voltage cutoff as slow as 9.3 Volts for example, on a 12 volt, which would put your cells around 3.1 volts.

Again, perfect voltage, low voltage cutoff for these cells, right? And the 24 is the same thing. 18.6 volt minimum cut up voltage, right? Which if you do the math right and the way you do that is, you would use two of these modules in series. So that's six cells and that would put your cells exactly at 3.1 volts. And it's the same thing with the 48.

The minimum cutoff uh, voltage is 37.2 Also, putting your cells out 3.1 volt was perfect. Low voltage cutoff all right next. BMS Now, luckily our supplier is giving us these modules with the wiring harness. so we have the connectors, but in case you were missing one or in case we didn't we don't have them or whatever or they're damaged for any reason.

Uh, we have the technical data here. The Mating Connector is Te174 68 72-1 and that is available at Bowser So here is what the connector looks like and here is the wiring diagram: I Know it says right there shows you the pins but it's kind of weird to see. So here's in graphical form: I Went and traced it all out and this is how you connect Cell number one, cell number two, cell number three. That is the wiring and then those two are the temp.

over here the one and two and and 12 and 11 pins are two temperature sensors. Now some of the connectors only have Uh connections for the one Uh temperature sensor right? So in case you wanted to add as the second one, then you would have to get the terminals which are also listed here in this document. Te 167 4311-2 All right it's of. the last thing for me to show you is how easy these mountains.

All right. With over 200 watt hours per kilogram, this is one of the lightest and smallest 20 kilowatt hours that I've ever seen, right? So this is. this is crazy small power wall. Here are all the positives and then here are all the negatives: I have gotten myself some Hardware here and then I made myself some bus bars I'm gonna install them then I'll show them to you All right? So we've installed these uh, stand ups there so we can move the plane up because I've made these bus bars here out of aluminum, right? and so that's how you can connect them.

Uh, but before we connect the positive, we we did the positive. Now to connect the negative, it would mean that we're gonna connect all of these in parallel. So before you do that, it's a really good idea to check to see. modules are all the same voltage and the way we're going to do that is by this little dongle that I made here I Just used just a regular connector here that comes with the thing and then I just put it onto this little guy in here all the voltages are matching.

Then we can connect them all in parallel here. 10.27 10.27 10.26 10.26 10.26 10.26 10.26 10.26 These are all perfect. All right. So here we go.

Now these are connected. These are all in parallel. This is one giant 10 kilowatt hour 12 volt battery and then this is another one. Now if I wanted to run 24 volts, all I have to do is connect.

Uh, this one the negative to the positive and now this is my main pot negative and my name positive. and now it's 24 volts and you have 20 kilowatt hour uh battery pack right here. Now if you wanted to do 48 uh, you can add two more of these in here. and then just connect them like that.

Uh, Also, you could just take, uh, break these into smaller uh, parallel packs right? So connect two in parallel and then connect the other two in parallel. Then connect those in series. You could flip these around or you can run a cable from here to there. and now this is your positive and this is your negative.

and then you can jump over down here. There's all kinds of ways. these are like Legos right? And so these bus bars here that I made I made them so you can connect. at the at the minimum you can connect two of these modules because then allows you to do all that to configure however you're going to want to do right.

But for 12 volts, you can use single like this in parallel. Uh, for 24 you use two. Uh, I Guess you could run this at 36 too, but nobody's gonna want to do that. but 48 you would run four groups of uh I mean either four in series or four groups of these in series and you can go as big as you want, right? So because I order a bunch of these and I don't really need them if you buy these, I'll include two of these.

Uh, with every module that you that we sell here right? So there you go, that's just to make it a little bit easier. Also, they will come with the connector uh and the connector. you can use it again I Showed you earlier how to connect that in there and maybe later because these will I will probably be getting more of these. I will show you how to do the full BMS connection on these guys.

So there you go. The smallest, lightest, and one really powerful. uh DIY Power wall right? I Want to thank you for watching this video. If you're interested in this, they're going to be at Jack35.com They're very very affordable.

A hundred dollars kilo an hour trying to help as many people get their battery sorted out. So for everything if you saw in this video, I will try and put the links in the description. Keep an eye out for the if it's not there. Just comment down below and then I'll do my best to try it and find the stuff and then link it in there right? Okay, thank you for watching.

See you guys on the next one. Bye.
