Oh hey, i got my braces off today, but you guys don't care about that. Let's talk about batteries, all right which battery should we talk about today? How about these ones? Right here we haven't talked about the 30 cell uh scooter battery packs. I mean you've seen them. I made a video where uh you know, i used them for an e-bike and that's what that's who's been buying these anyone that wants to build that e-bike on that video uh, then they're buying them and by the way, there's like about a thousand of you guys Have ordered like wheels and batteries right, but i came across a huge lot of these and these are the original ones that are on the xiaomi 356 scooter.
These are the stock ones. This whole fleet was decommissioned because uh the companies, you know they to change hands and so all of a sudden they didn't want these, and these are first generation scooters. So now they're going to second generation scooters right. So all of a sudden, these need a new home and someone dismantled a whole like thousands of these, his little scooters, and so i got the batteries.
I got pallets and pallets of these guys right, and these are great because, even though some of them are marked like this one right, this one's mark with the next, but i don't know why it's marked it's perfectly fine, in fact out of all these ones. Here it's fully charged this one's not fully charged this one there's one of these ones. That has a problem, and that is the thing that is. The issue is that these are untested right and so there's quick ways to test them to see if they're gon na work, if not right.
So when, if you buy one of these, it's gon na not come like fully charged, probably because they've been sitting there, and i just don't - have the time or the manpower to actually test every single one of these right. So that's why i'm selling them cheap, and so then what happens is that if you get them and if you go through a set of steps to try to wake it up and see if it's good and if you do find that it's not good i'll, just Replace it right, no big deal we'll just send you a label, you send it back to us and then we'll send you another one that is going to be good. Most of these are good right. The vast majority, and only a few of them here and there have issues right and so one way to test it out, uh to see if it.
If it's working see, these are blinking right. So when they're blinking, that means that they're on and they're good, but most of the times the ones that you're gon na get they're, not not gon na be blinking, and so the way to get them to blink again is to charge them. And you just put a charger: you connect the charger here and then what happens is that sometimes it'll start blinking right away, but sometimes it doesn't. It just stayed like that and then the light on the charger will start blinking, and so what that means is that the state of charge is very low and if you leave it there sometimes it'll take you know, depending on how low the state of charge on These batteries are it'll require, maybe a few minutes to maybe a few hours to i don't know, maybe a day or two and then because what happens is that only it's only charging when the light comes on and it only comes on for like a split second Right and so then it only charges.It's trickle charging the battery right just by little by little by little, because that's the safest way to do it right and so the charger eventually will. The light will stay on red, and that means the batteries are now charging and, after the turns fully read, it should only be about a couple hours for it to fully charge right, and so that's step. One then once it's fully charged right. This light goes to green if this light is still not turning on there's a couple ways to kick start this battery right, so one is to press on this little switch.
There is a little push button there, so what you have to do is you have to make a hole on this plastic here and then you click on it. You just push it with something in there and then the light will start blinking. That's one way to do it. Another way is to make a cable like this, with the spacing as 2.56 spacing uh we'll probably make these little dongles these little connectors in the future, but for right now, you'll have to make them and then what you do.
Is you install it here on this little connector and then you can apply the charger uh power in here and as soon as you do that, then the light starts blinking and if the battery is fully charged, it'll stay blinking like this, but if it's fully discharged, Then it'll turn itself off again. So then you can charge it through here or you can charge it to here and the proper way to charge. It is to do the small one right, it'll use the bms this one. I think it it uh.
There's some features on the bms that it skips right, and so i haven't done enough testing to see what we don't know if it balances through here or not, but you could charge them through here. You know there might be some higher risks of doing that, but we don't know we'll do some tests in the future and then we'll provide that information later but uh plug here it was the one that it was designed to charge, and so maybe it's just easier To charge it to there, except you'll, have to make this cable right and again, we'll probably offer that cable in the future, but for now, once you have your battery and it's blinking like this, what can you use it? Well, you could use it to put it on a uh scooter, the scooter that was designed to or you could do, build a diy scooter and put it in there right or you can build a diy e-bike, and what happens is that this one has enough power Right, it's got 30 cells, each cell is 10 watt hours, so it's 301 hours right, which is let's say here, yeah 280. But we know it's it's 301 hours, because each cell is 10. um, and so this one could do about 300 watts of power, which is not huge power, but on a diy, e-bike right, 300 watts.That's enough to you know not have to pedal right. But if you do pedal uh, then it's even better because it uses less power. So we had a customer build an e-bike using this and he said he got like somewhere like miles of range uh with the pedal assist, and so you know this is a pretty good value right to get 20 miles off of this, you could buy two of These and then just connect them in parallel. They make these little cables that you can buy at amazon, and then you just connect those in parallel there and then you can nag down on the one.
That's coming out to your e-bike, and now you got like. I mean you got long-range range right, you don't have to worry about making it or not and it becomes a battery. It's not super huge right, it's about average size for an e-bike and obviously with the the doubling like the capacity. Also, the amperage right, the power rating goes up because now, all of a sudden you'll be able to do well, 20 amps uh about 600 watts and 600 watts.
Now you know now it's getting a little bit better, so you could do that. What else can you do by the way they come in two versions? The only difference is this type of cells, the uh lg m26s right. These are the purple ones and then the eevee cells are very similar, they're about equivalent uh performance of cells and quality of cells right. So it's just one or the other one, all right, one of the things that we are doing with all these scooter uh battery packs is we are expanding.
The capacity of some of these store-bought uh battery boxes right. This one right here happens to be one of my favorite ones: the eco flow delta mini it's really small and light, and it still puts out a quite a bit of power about 1400 watts. So you could power. I mean you can power that uh ac unit with this thing right, um, the problem of, of course, with ben being so small, is that it doesn't have a lot of battery inside.
So what you can do is you can expand that battery by putting external batteries and what you do, how you do it is you put this battery straight into the solar input of this unit right here right, so it's as simple as this you charge this battery. Then you make the right cable, it goes from x, x, t 30 to an x t 68 back there, and then you just connect it in here there we go. It's connected. You wait a few seconds.
The unit comes up. It recognizes there's voltage in the uh solar charging and there we go it'll start charging about 300. Oh it's collapsing. Why is it collapsing? Oh okay, so that i realized this is the one that's fully discharged it's at 31 volts right.
So this one it's fully charged. Let's plug it in plugged in there we go detected that there is a battery or there's a voltage on the solar charge port and there we go it'll start charging around 300 watts. So it's going to transfer it's 300 watt hours of energy from this battery into here, and you could of course, always get another one. And now it's about the same size as the internal battery or you can get a third one and a fourth one and then all of a sudden.You got more battery out here that you got in there. But as long as you connect that in there, then you just expanded the battery. Now this becomes a much much bigger battery that could now potentially serve your needs. If the internal battery, that's in here doesn't right and it keeps it everything light and small and portable and those are the things that we're doing with these.
Obviously, you could also get rid of these store-bought products right then. You could also just connect these batteries into a 36-volt, inverter and it'll do the same thing, but a much much cheaper price right and you could do way more. This is a 3000 watt inverter. Of course, uh yeah this - these four packs right here will be able to do about 1200 watts right.
So you could connect all these cables in parallel and then connect them to the back of this inverter and then just operate that so you in assassins you can do. Is you can build your own solar generator right? There we go. We just do put those two in a box put a thing around put the connectors, then you can include the charger bam there. You go.
That's the beginnings of a diy, solar generator that you can build using these 36 volt batteries. So the possibilities are endless. With these and you can build, you can get creative and build a bunch of stuff and uh. These are good quality battery cells, uh and they're already made.
So it kind of takes all the work of putting battery packs together for you, and then you can build stuff. All right, so go build some batteries with these all right. That's just another one of those batteries that we've had for a while, and i hadn't had a chance to make a video about so there you go now that you've seen it uh. Hopefully, you can build some cool projects using them and then you can share them with us so that we can all get inspired and do our own diy projects there you go.
Thank you we'll see you guys in the next one bye so time.
