All right Video time. Let's talk about batteries today. We're going to talk about this battery right here. It comes from a hybrid car.

it's a 12s battery. You make videos about it before. uh, 44 volts, right? So it's not quite standard for like a 48 volt inverter. but they do make.

check out this inverter. It's made for the Tesla power packs which are 6s so you have to use two of them in series which makes 12s. so that's engineer. So that inverter right there.

uh actually there's a couple of them. uh will work with these batteries. but I also I think I have an inverter that I want to try and see if I can get it to work, see how much, uh, you know how much of the battery capacity would be left on the table because of the discrepancy and the voltage. So in order to do that I have to figure out this pin out here because well, it kind of makes sense to just figure out how to connect these without the least amount of work, right? So I don't want to have to come in here and undo all these wiring and stuff so the pin out here.

So we're gonna figure out the pin out I'm just going to do it off camera and then I'll show you to you once I'm done. Okay, so it looks pretty straightforward. It looks like the uh uh. most negative is that one on the upper left and then a number two is going to be the one below it and then it's gonna zigzag this way and not away in this way until you get all, um, 13 pins because these are 12 cells so there's nothing here other than that there is that last pin there is not used for anything.

There's a 14 pin connector, but only 13 are being used. So while doing this I realized that these pins from these Mana key connectors are the roughly the same size. so they work right. You move them around and they they don't get disconnected.

So I think they're the exact same, uh, diameter, uh, that you need to put in there. The only difference between these, the reason you can't just stick them in there is because the spacing is different. These are 2.54 millimeters apart, so it's slightly more than two and a half millimeters and this has a pitch of three millimeters so there's three millimeters between those. Either way, down, this was three millimeters and then down that way it's three millimeters.

and so we haven't been able to find this connector. We're looking. We order a few uh that seem like they are similar, but they don't. There's no right and so as of right now we still don't know.

Some people are saying OBD connectors but I'm looking at a bunch of pictures and the OBD connectors look different and they said maybe the Japanese version of the OBD connector. so we're just kind of looking for them until we do find that. I Think something like this would work, but this is a bit of a work I think I just designed a little PCB board that we I'm going to be able to put and stick these. You can get these without this connector right here and so you easily can stick them in there and solder them and then just solder the whole board in there.

and that's one quick, easy way to get a around the fact that these connectors might not be available or readily available or easily available and so after that, then what we're going to do is we're going to connect a bunch of these in parallel, which is the easier just positive to positive, negative to negative. and then we're going to try to connect an inverter, a 44, a 48 volt inverter and just see how much capacity we can get out of them. This is slightly more than one kilowatt hour and you know by being lower voltage are we going to lose some because you're not going to be able to discharge them all the way. That's the test that is that I'm coming and working.

So for right now we figure out the pin out all right. Thank you for watching this video. If you're interested in those batteries, they're at Jack35.com They're very, very powerful batteries. These are like 10, 15 C batteries, right? So very powerful.

Uh uh. They're kind of odd at 12s, right? So there's we're trying to find useful applications for them and trying to find all the connectors so that it becomes easy for people to use them and connect them right? So thank you again! We'll see you guys on the next video. Bye.
