Hey there, let's talk about batteries. One of the questions we get a lot is how to install a BMS on a battery and specifically how to to combining 224 volt modules into 48. And the reason why that seems to be a question is because we make a bunch of 24 volt modules right? 7s like this, like these ones and then the bigger ones that we're starting to make. and the reason we make them in 24 volts and not 48 like a lot of you guys want them.

It's because if you may come 48 then you can't use them in a small system that is 24 volts, right? But if you make them 24 volts then you can use them in small systems for like RVS and stuff like that. Um, and you could also just scale up by connecting two of these modules in series and then using them in larger 48 volts systems. And so that's why you can do both. You can do small systems and bigger systems with the same one, but people have trouble figuring out how to combine two two of these 24 volt modules and then connecting a 48 volt.

BMS So today I'm going to show you one little tool that I've made here and this is one of a series of tools that that we have right? These are 48 Volt, 14s, BMS and I'm going to show you how to connect using this thing into our line of modules because they all use that same little connector here. This is an IDC connector 16 pin and so because of that, well connecting a BMS should be pretty simple using this little tool here. So let's go to Bench over there and show you how to do it. Okay, let's use these yet unreleased Sonata modules, right? But these are very similar to the other ones.

We have Uh, Boston swing modules. We have the other ones that are over there and they always share that same 16 pin connector, right? So if you connect these guys in parallel van, uh, it's a 24 volt battery and each one of these ones, it's one kilowatt hour and so you'll have two kilowatt hours at 24 volts. But if you wanted to connect, Oh, and if you wanted to connect a BMS all you have to do is use this little guy and you put it in there and you connect with this little ribbon connector. You connected in here and now you have these little screw terminals to connect your BMS And so that's pretty straightforward.

You could use it here and then you can daisy chain from here to Here and Now. Those two are connected in parallel and that same BMS is. uh, managing this both Uh modules here so you can do each individual module with the Zone BMS Or you can do a master BMS that is shared throughout the whole thing. This becomes one battery, right? Even those two modules.

So there's that we make one that is an 8s Uh, for Lithium iron phosphate batteries, right? and then this one right? here. And so this one's a bit different because let's say that you don't want these two modules to be 24 volts, You want them 48 and so you would have to connect them in series. So the positive. Uh, this is the positive, this is a negative and then the negative.

You connect it to the positive and then these two are going to be your exit points, your outputs right. and so you'd have to put it through a BMS like this one here. And so let's say that you want to do that with that right? So we'll use some paper here so that it doesn't Arc We're gonna put the BMS right here on top. Just the these surfaces are exposed so we don't want this to Arc and uh, short and stuff.

So here is the adapter and what this does is combines both of these to in series so that you can connect your BMS. So what you do is you put it in here and then you connect these guys. Okay and then you connect this guy here. Okay so now your BMS is connected to these two modules and all you would have to do is bridge this one right here.

The positive and the negative. These two modules and then the negative. this negative which has to go on through the BMS So this cable goes connected over here and then this is going to be your positive and then this is going to be your main negative for your load and this is going to be your main positive. And then this one's going to go through here, right? And that's as easy as it is to connect a BMS on 224 volt modules to make them into 48, right? These little adapters are going to be at Jack35.com Follow the link in the description and you will be able to buy them and these work with any of our batteries that have the 16 pin uh IDC uh socket connector right later.

We also: I Guess we're gonna make some modules that are going to have these things installed in there so it'll be easier to connect the BMS directly into the modules without having to use this, right? But for right now, a lot of you guys have these modules that we've been making for for a while and they have this connector and so this adapts that and it makes it super simple, super clear, and super clean to install a BMS on your batteries. So there you go. Thank you for watching this video And if you want to see Uh and buy one of these things, just go to Jack35.com The description, the links in the description. We'll see you guys on the next one.

Bye foreign, foreign, foreign laughs Laughs Foreign Foreign.
