WEBVTT 00:00:00.080 --> 00:00:07.680 I've spent the last several years remodeling my home into a techie's dream 00:00:04.799 --> 00:00:13.719 with gaming PCs, 10 gig networking, and screens everywhere. And it's kind of 00:00:10.240 --> 00:00:17.840 awesome. But there is one 00:00:13.719 --> 00:00:19.840 one fatal flaw. Despite the solar panels 00:00:17.840 --> 00:00:25.359 we installed on the roof providing some clean energy some of the time, the 00:00:22.640 --> 00:00:30.400 system was designed to feed excess power back into the grid rather than into a 00:00:28.080 --> 00:00:35.640 battery bank. So during the stormy season, we regularly lose the one thing 00:00:32.800 --> 00:00:42.320 a techie house needs more than anything else. Come on. The power and these 00:00:40.079 --> 00:00:48.239 outages seem to be happening more and more frequently. So it's time to solve 00:00:44.800 --> 00:00:52.320 this once and for all with a proper home 00:00:48.239 --> 00:00:52.320 power backup solution. 00:00:53.480 --> 00:00:57.480 Jake. Jesus. 00:00:59.120 --> 00:01:03.440 Jake, this is not what we talked about. What do you mean it's mint? I thought 00:01:02.160 --> 00:01:10.400 you wanted something cheap. Well, yeah, of course I want something cheap, but I want something safe. Um, I've got 00:01:07.040 --> 00:01:12.479 paperwork. Hold on. See, like, look, 00:01:10.400 --> 00:01:17.040 that's not the paper. That's just our sponsor, War Thunder. If you're into 00:01:14.640 --> 00:01:21.200 vehicle combat games, War Thunder has a ton of depth while being easy to get 00:01:19.200 --> 00:01:26.400 into. And it's available on PC, consoles, and mobile devices. Play for 00:01:23.439 --> 00:01:30.560 free using the link in the description. Got him. You see, Lionus isn't the only 00:01:28.560 --> 00:01:34.960 one who's tired of our crappy power grid. And when I heard him complaining 00:01:32.240 --> 00:01:38.799 about it, it gave me a wonderful idea. Why spend my time building a 00:01:37.119 --> 00:01:41.840 cost-effective battery backup system for my house when I can get paid to do it 00:01:40.320 --> 00:01:47.040 instead? It's just that when I pitched doing a sort of DIY, build your own 00:01:43.920 --> 00:01:48.799 battery toolinus, he was understandably 00:01:47.040 --> 00:01:53.040 a bit sketched out. So, I told him, "Don't worry, we'll just buy a complete 00:01:51.040 --> 00:01:57.360 solution and then all we've got to do is hook it up." Which is exactly what I 00:01:55.439 --> 00:02:00.960 did. There's just uh maybe a little bit more assembly required than I think he 00:01:59.680 --> 00:02:04.719 was expecting. Now, if you've been keeping up with the Lionus house 00:02:02.719 --> 00:02:09.599 renovation project, you might have seen the Eaton UPS or uninterruptible power 00:02:07.439 --> 00:02:14.239 supply units in his rack. Yes, the one that got water all over it. That box is 00:02:11.920 --> 00:02:18.720 basically a fancy battery that sits in between his networking, smart home 00:02:16.480 --> 00:02:22.239 control, everything in his server rack, and as the name implies, provides 00:02:20.400 --> 00:02:26.480 uninterrupted power to it in the event of an outage. The problem is they're 00:02:24.319 --> 00:02:30.319 just only really designed to run for like a couple minutes. Just enough time 00:02:28.319 --> 00:02:35.040 to save your work and shut down or in a larger scale setup like a data center. 00:02:33.040 --> 00:02:39.519 Enough time for a generator to start up and fill in for the grid. Not nearly 00:02:37.040 --> 00:02:44.560 enough for a several hourong outage. And while we could extend it with extra 00:02:41.920 --> 00:02:50.959 eaten battery packs, at a retail price of 00:02:46.599 --> 00:02:52.879 $1,500 per piece, even $6,000 later, 00:02:50.959 --> 00:02:56.879 we'd still only have a few hours. Now, other setups like the Jackaryi I kind of 00:02:54.560 --> 00:03:04.640 hinted at earlier could power the whole house. But with 10 kwatt hours costing 00:03:00.519 --> 00:03:07.120 $6,000 as well, DIY it is. Starting with 00:03:04.640 --> 00:03:12.000 the batteries. Now, in a normal whole house setup, in this day and age, you 00:03:08.959 --> 00:03:13.599 would usually go with LFP or lithium ion 00:03:12.000 --> 00:03:18.720 phosphate batteries. They're much more affordable than the solutions I just mentioned per kilowatt hour. But more 00:03:16.720 --> 00:03:21.920 importantly, they're less explosive and have longer usable life than the 00:03:20.239 --> 00:03:26.239 batteries we're going to be using today. Specifically, these four battery modules 00:03:24.159 --> 00:03:31.440 we picked up from a scrapped Tesla Model S battery. They were $250 a pack, and 00:03:29.040 --> 00:03:35.200 that is really freaking cheap. And since I'm not exactly sure how Linus is going 00:03:33.440 --> 00:03:39.519 to feel about all this, these were a solid way to start a bit smaller. Not to 00:03:37.599 --> 00:03:43.360 mention that these packs have a built-in balance and sensor board, which helps 00:03:41.680 --> 00:03:48.480 with the safety factor, and we'll talk a bit more about that later. Because the 00:03:45.680 --> 00:03:53.599 400 odd cells in this pack are primarily wired in parallel, which adds capacity 00:03:51.360 --> 00:03:58.400 rather in series, which adds up the voltage. Each pack is only around 24 00:03:56.319 --> 00:04:05.200 volts, but we need 48. So, we're going to take each pair and wire them together 00:04:02.879 --> 00:04:08.480 in series, which will give us the exact same 48 volts. So, why don't we start 00:04:06.640 --> 00:04:12.159 with that? This specifically is 4 gauge. Now, the gauge of the wire, which is how 00:04:10.319 --> 00:04:15.040 thick it is and how much power it can handle, is really important. Um, but 00:04:13.920 --> 00:04:20.160 we're not going to get into that just yet. We'll talk about that in a little bit. But what is important is how you 00:04:18.239 --> 00:04:24.960 terminate it. They're actually Molex brand. Yes, that Molex, but no, not that 00:04:22.560 --> 00:04:30.479 connector. These connectors are much, much beefier. So much so that you can't 00:04:28.000 --> 00:04:33.840 put this on this cable without a special tool. Because even if you had a big pair 00:04:32.160 --> 00:04:38.000 of pliers, the odds that you're going to be able to put enough force on this to 00:04:35.360 --> 00:04:42.639 actually get a good connection, very unlikely. So instead, we're going to use 00:04:40.080 --> 00:04:46.720 this, which is a hydraulic crimper. We picked this up on Amazon for about 100 00:04:44.160 --> 00:04:51.840 bucks. And if you look at it closely, as I pump the lever, once it gets tight, 00:04:49.759 --> 00:04:56.920 it's exerting a ton of force on that connector. 00:04:53.440 --> 00:04:59.720 See, that is not going 00:04:59.720 --> 00:05:08.880 anywhere. So, if we grab our lovely Fluke 117 multimeter here and measure a 00:05:05.680 --> 00:05:11.520 single pack, we've got 23.4 volts. And 00:05:08.880 --> 00:05:17.440 then if I go to measure uh the whole pack from negative to positive, 46. You 00:05:15.280 --> 00:05:21.360 can even see our meter is in DC mode. Batteries are DC. And that means 00:05:19.440 --> 00:05:24.240 basically that one side is positive and one side is negative. and the 00:05:22.639 --> 00:05:30.080 electricity flows one way. You can see if I flip these around and put the positive lead on the negative side and 00:05:27.520 --> 00:05:35.120 vice versa, we get negative voltage. Now, the power in your house, however, 00:05:32.240 --> 00:05:38.960 is completely different. It's AC or alternating current. And if you were 00:05:36.720 --> 00:05:43.440 able to check, you know, negative versus positive on that, please don't try. You 00:05:41.280 --> 00:05:48.240 would see that the hot wire actually switches between negative and positive 00:05:45.840 --> 00:05:51.680 60 times a second. At least in North America, you you can't just like hook 00:05:50.320 --> 00:05:56.320 one of these batteries straight up to the wall. Please, please do not try 00:05:53.680 --> 00:06:00.479 that. Instead, you need something called an 00:05:57.800 --> 00:06:04.479 inverter and a charger. Oh my gosh, this is heavier than I was expecting. An 00:06:02.080 --> 00:06:08.800 inverter takes the DC charge from our batteries and gives us AC wall power. 00:06:07.199 --> 00:06:12.639 And then it also does the opposite because this is a hybrid. So, it'll take 00:06:10.479 --> 00:06:15.919 wall power and give us DC power to charge the batteries. So, it's an 00:06:13.919 --> 00:06:21.600 inverter charger. And the one we're going to be using, this EG4 6000XP, is 00:06:19.120 --> 00:06:24.880 specifically designed for 48volt battery systems, which is why we put the 00:06:22.960 --> 00:06:29.120 batteries together earlier. And if we open it up, we can see all sorts of 00:06:27.039 --> 00:06:34.319 connections in here. We've got the big old battery terminals. This thing can do 00:06:31.680 --> 00:06:38.160 a lot of battery. We've got load, which is what you connect anything downstream 00:06:36.160 --> 00:06:41.520 that you want battery backed up. We've got grid, which is the incoming power, 00:06:40.160 --> 00:06:45.520 so we can charge the batteries with that. It can pass it through when we're 00:06:43.199 --> 00:06:49.520 not on battery. We've got gen, which is for a generator, which Lionus doesn't 00:06:47.360 --> 00:06:55.440 have, but all of the units kind of in this price point seem to have that. So, 00:06:52.319 --> 00:06:56.960 bonus feature, ah, and then PV input. 00:06:55.440 --> 00:07:00.880 This is meant for connecting solar panels directly to the inverter charger. 00:06:59.520 --> 00:07:04.560 If you're doing like an off-grid installation, like at a cabin where you 00:07:02.560 --> 00:07:09.759 don't even have a grid to connect to, this specific unit, because it's called 00:07:06.240 --> 00:07:11.840 the 6000 XP, can handle 6,000 watts of 00:07:09.759 --> 00:07:16.319 power. And in a normal home battery setup, you'd take what you would call a 00:07:14.240 --> 00:07:20.639 critical load panel, which is just a separate electrical panel, and wire up 00:07:18.800 --> 00:07:24.639 all of the things that you need to power in an outage, like say medical equipment 00:07:23.280 --> 00:07:28.479 if you have something like that, or controls for like a gas heating system. 00:07:26.800 --> 00:07:33.680 That way, you're not wasting battery powering the entire house when you don't 00:07:31.759 --> 00:07:38.160 really need to. In the final installation, we're probably just going 00:07:35.520 --> 00:07:42.639 to power the whole house. However, for now, we're just going to set this up as 00:07:39.840 --> 00:07:47.759 a completely standalone system, just like a UPS. And in our case, our 00:07:45.199 --> 00:07:53.560 critical load, which is the server rack, it's already separated onto two PDUs, 00:07:50.240 --> 00:07:57.120 which are basically fancy power 00:07:53.560 --> 00:07:58.479 bars. A lot has changed, as you can see, 00:07:57.120 --> 00:08:04.639 and obviously there's a lot of pieces here that we haven't talked about at all yet. So, let's do it. Now, you can just 00:08:02.879 --> 00:08:09.919 take our batteries over there and hook them right up to this. It would work, 00:08:07.120 --> 00:08:13.280 but it's not exactly safe. Primarily, if there's any sort of issue with this, not 00:08:11.840 --> 00:08:18.319 to say that there will be, but if there was, that caused the pack to draw too 00:08:15.599 --> 00:08:22.319 much power, we don't want our cables to be able to melt or for instance, if 00:08:20.720 --> 00:08:26.800 somehow one of them got caught and shorted itself out. We want that system 00:08:24.720 --> 00:08:30.879 to automatically be safeguarded against that. And to do that, you use fuses, 00:08:29.039 --> 00:08:35.519 which do exactly that. These are rated for 80 amps. And there is kind of like a 00:08:33.039 --> 00:08:38.959 a table that shows you at what amperage and what amount of time they blow. But 00:08:37.440 --> 00:08:43.599 the main thing is if our battery pack gets shorted out for some reason or is 00:08:41.519 --> 00:08:47.519 drawing way too much power, this fuse will blow and break the path of 00:08:45.600 --> 00:08:51.760 electricity. So it doesn't start a fire or at least in theory. And we have one 00:08:49.839 --> 00:08:55.600 of these for each of our series pairs of batteries. and they'll just sit in this 00:08:53.360 --> 00:08:59.839 little fuse holder thingy here, which conveniently has a bus bar on the other 00:08:57.680 --> 00:09:04.160 side that'll connect our two sets of packs together to get all of our 00:09:01.720 --> 00:09:07.360 capacity into the inverter charger right here. There's also another safety 00:09:05.839 --> 00:09:10.959 measure right here, which is called a contactor. And it's basically an 00:09:09.279 --> 00:09:14.160 electronically controlled light switch, just like an electronically controlled 00:09:12.720 --> 00:09:19.200 the biggest light switch you could possibly imagine. This thing can handle 00:09:16.000 --> 00:09:21.360 900 volts DC and I think like how many 00:09:19.200 --> 00:09:25.600 amps? I don't know. It doesn't matter. a freaking lot of amps. Way more than you 00:09:23.200 --> 00:09:29.279 could possibly need in this pack because this is actually pulled out of a car if 00:09:27.519 --> 00:09:33.839 there's any sort of issue with the pack. Ideally, we're detecting that ahead of 00:09:31.360 --> 00:09:36.640 time. And the conttor will shut off the power. And how do you know if there's 00:09:35.360 --> 00:09:42.480 anything wrong with the batteries? Well, the Vero Electric BMS V2, this thing is 00:09:40.480 --> 00:09:47.360 the brains of our operations, or at least of the battery side. This thing 00:09:44.800 --> 00:09:51.680 allows us to talk directly to the Tesla module balance boards and read the 00:09:49.600 --> 00:09:56.240 temperatures, the voltages, everything. But more importantly, it controls our 00:09:54.560 --> 00:10:00.000 contacttor big switch thing. So, if there is any problem with the pack, 00:09:57.920 --> 00:10:04.240 something doesn't seem right, it shuts the power off and makes sure that 00:10:01.600 --> 00:10:08.959 nothing breaks. Oh, and I almost forgot. There's one of these little clampy boys. 00:10:06.000 --> 00:10:13.519 It's called a CT. uh it just goes on the negative wire and feeds back information 00:10:11.440 --> 00:10:17.279 into the BMS to tell it how much amperage is going through so we know how 00:10:15.600 --> 00:10:20.560 much it's being charged or discharged at any time. Now, we need to talk about how 00:10:18.959 --> 00:10:25.279 we're going to connect to the house to get our incoming juice and connect the 00:10:23.279 --> 00:10:29.120 rack to power the rest of the devices, especially when a power outage happens. 00:10:26.959 --> 00:10:33.360 So, in North America, we have a little bit of a complicated situation. You see, 00:10:30.959 --> 00:10:37.920 this is a normal power plug. You've got one wire that comes into here that gives 00:10:34.959 --> 00:10:42.560 you 120 volt AC and the other wire is neutral which is not technically a live 00:10:40.240 --> 00:10:48.880 wire technically technically except that in an electrical panel you also have 00:10:45.440 --> 00:10:51.200 line two. So there's two these two wires 00:10:48.880 --> 00:10:56.800 line one and line two are separated by 240 volts AC and the neutral just sits 00:10:54.880 --> 00:11:00.959 in the middle. And so if you connect neutral to line one you get 120 volts. 00:10:59.120 --> 00:11:05.360 If you connect neutral to line two you get 120 volt. But you have to deal with 00:11:03.360 --> 00:11:12.720 both of these if you want to be able to back up an entire house or in our case 00:11:08.480 --> 00:11:14.320 in Linus' rack, we have 240 volt and 120 00:11:12.720 --> 00:11:19.519 volt. So we need to be able to power both of those devices. Now our inverter 00:11:16.959 --> 00:11:24.320 is built for this. We've got L1, we've got L2. That's fine. It's just that at 00:11:22.880 --> 00:11:28.560 the house it becomes a little bit complicated because we need to get all 00:11:26.399 --> 00:11:32.200 of this on one plug ideally. And it just so happens that there's a solution for 00:11:29.839 --> 00:11:36.160 this. this fancy plug called an L1430. The 30 standing for 30 amps, the 00:11:34.720 --> 00:11:42.800 14 standing for whatever the heck this is. Gives us L1, L2, and neutral. Of 00:11:40.560 --> 00:11:47.600 course, also a ground. And that means we can pull 120 volt and 240 volt off of 00:11:45.360 --> 00:11:52.560 this one plug. From here, we'll run a big wire that can handle that 30 amp 00:11:49.360 --> 00:11:54.000 load. It'll wire into L1 and L2 on grid. 00:11:52.560 --> 00:11:59.120 Then we'll have our neutral on the neutral and then our ground into PE for 00:11:56.720 --> 00:12:03.920 protected earth. And that's pretty much it on the input side. From the output 00:12:01.440 --> 00:12:08.000 side, it's kind of the same story except that instead of wiring directly to a 00:12:05.760 --> 00:12:13.920 plug, we need two plugs. So, I've got an L630, which connects to the PDU and 00:12:10.320 --> 00:12:15.680 gives us 240 volt only, not both. And 00:12:13.920 --> 00:12:20.079 then we've just got a normal receptacle, which will be our normal 120 volt. 00:12:18.079 --> 00:12:24.480 Huzzah. With a little movie magic, now we're in Lionus' basement. And we have 00:12:22.560 --> 00:12:28.399 everything here a little bit more put together than the last time you saw it. 00:12:26.160 --> 00:12:32.399 I've done a bunch of wiring. We've got our output side all put together how we 00:12:30.480 --> 00:12:36.320 talked about before. We don't even have the Tesla batteries hooked up yet. I 00:12:34.639 --> 00:12:40.320 don't even have the cables made. But the next step is getting this thing on the 00:12:38.079 --> 00:12:44.560 wall. I guess it has to go right here. This is pretty much the only option. And 00:12:42.399 --> 00:12:48.959 Lionus isn't home right now. He's in Asia on vacation, which means I get to 00:12:46.880 --> 00:12:52.000 put it wherever the I want. Now, before we do anything funky like getting this 00:12:50.560 --> 00:12:57.120 wired up to the house, I'm going to hook this up with a different battery than 00:12:53.920 --> 00:12:58.720 our Tesla packs. specifically this one 00:12:57.120 --> 00:13:04.480 also made by the company that makes the inverter EG4. Now, if you're looking for 00:13:01.200 --> 00:13:06.800 a more oh my god offtheshelf solution, 00:13:04.480 --> 00:13:10.399 this is something you can look for. It's basically a rack mount unit made with 00:13:08.720 --> 00:13:14.399 LFP batteries, which we talked about earlier. They're a lot safer and it 00:13:12.240 --> 00:13:17.760 includes all of the safety and battery management stuff in this unit. It is a 00:13:16.240 --> 00:13:21.760 fair bit more expensive than rolling your own solution, but you press the 00:13:19.680 --> 00:13:25.440 power button here. It boots up. It's ready to go. And it hooks right up with 00:13:23.440 --> 00:13:30.000 some RJ45 for communication with the inverter and some power leads. Damn. 00:13:28.240 --> 00:13:34.880 Hey. Yeah, that's good. That's not half bad. Perfect. Let's slide this in the 00:13:32.800 --> 00:13:38.600 corner, measure some cables, and then we'll reuse them for our temporary 00:13:36.399 --> 00:13:42.160 battery and save these for Linus. And when you're hooking up a 00:13:40.560 --> 00:13:46.399 battery system like this, it's very important that you get wire that is 00:13:44.079 --> 00:13:50.240 thick enough to handle the amperage or the amount of energy that you're passing 00:13:48.000 --> 00:13:57.199 through it. And this 6,000ish watt inverter means at 48 volts peak 00:13:54.519 --> 00:14:02.639 load 125 amps. That's a lot of freaking amps, man. And since we have two packs 00:14:00.720 --> 00:14:06.320 kind of that are being put together, we divide that by two. That means an 00:14:04.079 --> 00:14:11.279 individual pack could be pulling anywhere upwards of 62 amps. And if we 00:14:09.199 --> 00:14:16.079 look at our handy ampacity chart, which tells us what wire gauge you need for a 00:14:13.440 --> 00:14:21.199 given amperage, we'll say 62 amps. So we'll go 70 is 6 gauge. And this is 4 00:14:18.959 --> 00:14:25.920 gauge. So, we're good to go. The 4 gauge should be able to handle up to 100 amps. 00:14:23.040 --> 00:14:31.120 So, this is lots. About that much ran into our fuse. And we actually have a 00:14:28.160 --> 00:14:35.600 fuse for each of our pairs of packs. That way, if all of the power for the 00:14:33.360 --> 00:14:40.560 full 6,000 watts was going from one pack, this fuse will blow and shut the 00:14:37.440 --> 00:14:42.079 whole system off. Oh. Oh, fresh. Oh. 00:14:40.560 --> 00:14:49.600 because I just want to see this thing turn on. I'm going to do something mildly cursed and use both red cables as 00:14:47.440 --> 00:14:54.000 the positive and the negative for our pre-made battery from EG4. Now, if 00:14:51.839 --> 00:15:00.279 you're doing this properly, you should use a torque wrench. I'm just going with 00:14:56.880 --> 00:15:02.600 tight. If we clip this 00:15:00.279 --> 00:15:09.560 on, hey, it's on. Please do not ever do this 00:15:06.320 --> 00:15:09.560 at home. 00:15:11.040 --> 00:15:18.639 Hey, look at that. You seeing it? 120 volt AC, baby. Now, my plan was to use 00:15:16.320 --> 00:15:24.639 this plug, an L630, which powers his main big UPS with 240 volt power. The 00:15:21.920 --> 00:15:29.360 problem is, despite what the panel was labeled, this is only a two wire cable, 00:15:27.760 --> 00:15:33.279 which means we have line one and line two with no neutral, and we need the 00:15:31.360 --> 00:15:36.639 neutral. So, we walk into the electrical supply store, and the guy's like, "Yeah, 00:15:35.440 --> 00:15:40.399 they they won't they won't do that. They won't cut it off the roll." I'm like, "What do you mean they won't cut it off 00:15:38.720 --> 00:15:46.399 the roll?" Look at how many rolls you have. Look over there. There's even more 00:15:43.440 --> 00:15:49.839 rolls. Well, we got it, though. He He magically cut it off the roll for us, I 00:15:48.480 --> 00:15:54.759 guess. So, I did a bunch of electrical work in your house, added a new plug, and in theory, 00:15:55.199 --> 00:16:02.880 it's really theory cuz I haven't tested this part. 00:15:59.639 --> 00:16:05.680 Hey, and then this is just batteries out 00:16:02.880 --> 00:16:10.079 of what? A Model S? Yes. What' we pay for them? very little. For the 00:16:07.519 --> 00:16:15.759 uninitiated, this is 20,000 watts for an hour or 1,000 watts for 20 hours. 00:16:14.160 --> 00:16:20.320 Assuming no losses and whatnot. We're just Yeah, perfect world. Anyways, and 00:16:17.839 --> 00:16:27.519 it was 1,000 bucks Canadian, which what Americans is like 600 US, dude. That is 00:16:24.320 --> 00:16:29.279 5 kW hours and is $2,000. For the big 00:16:27.519 --> 00:16:33.519 deployment, we're probably not going to actually use these. We will we will use 00:16:31.199 --> 00:16:37.519 LFP batteries, but we'll build our own pack. Basically, I don't know too much 00:16:35.759 --> 00:16:41.920 about the battery packs in older Model S's. I know these are 18650s 00:16:40.399 --> 00:16:47.519 and there's a freaking lot of them. I think there's 444 in each of these. And 00:16:45.120 --> 00:16:52.079 then uh how many packs would be in a full car? Uh I believe there's 16 00:16:50.160 --> 00:16:56.240 modules in a whole battery pack in a Model S. Notice how these are exactly 00:16:54.320 --> 00:17:00.000 the same length. Yes. It's very important when you're building a battery 00:16:57.519 --> 00:17:03.680 pack that you have equal lengths between all of your different cells because you 00:17:01.839 --> 00:17:06.240 don't want to be charging them ever so slightly different. Is this off here for 00:17:05.039 --> 00:17:11.919 a reason? It could just go anywhere on there, right? Just put them here. So, I could also just put it here. What 00:17:10.160 --> 00:17:15.760 happened to the nut? What am I doing? I'm drunk. You are drunk. What? Look at 00:17:14.480 --> 00:17:23.439 this. Oh my god. I put that one on backwards. You are so drunk. I mean, it would still work. Now, we plug in the 00:17:20.319 --> 00:17:25.600 BMS. Yeah, that has a mount. Look how 00:17:23.439 --> 00:17:30.480 mounted that is. Oh, man. We can see our batteries are 27° 46.7 volts at a 62% 00:17:28.880 --> 00:17:35.600 state of charge. I actually hadn't tested this contactor yet. If we were to 00:17:32.960 --> 00:17:39.360 go like this. Uh-huh. Do you hear that? Yeah. That was 00:17:37.600 --> 00:17:43.120 the contact. What's one of these worth? I think this is about 2 grand Canadians. 00:17:40.799 --> 00:17:48.000 It's about 1,500 bucks. That's not bad. Considering it can do six kil watts. 00:17:45.520 --> 00:17:51.600 Yeah, I didn't. I was just I was just chilling there. That's confidence 00:17:49.360 --> 00:17:57.520 inspiring. Look how mounted that is. Ah, mint. Presently, our BMS cannot talk to 00:17:55.280 --> 00:18:00.960 the inverter over CAN and like have a nice communication and tell each other 00:17:59.039 --> 00:18:04.240 what's going on. However, I did yell at both of the companies and they have been 00:18:02.640 --> 00:18:08.880 for like the last 3 weeks working on getting them integrated. So, Oh, that's very cool. In a couple weeks, you 00:18:06.960 --> 00:18:11.760 hopefully will be able to use an EG4 inverter with a VO BMS and they'll just 00:18:10.799 --> 00:18:17.679 talk to each other and everything's good. Super cool. For now, we have to run it in lead acid mode. Lead acid mode 00:18:15.520 --> 00:18:20.960 is basically you don't have a lithium battery that has a battery management it 00:18:19.520 --> 00:18:25.120 can talk to. So, we could set the charge current to whatever we want if we wanted 00:18:22.559 --> 00:18:29.200 to control temperatures or Yeah. 100%. So, actually in a Tesla, I mean, if you 00:18:27.600 --> 00:18:33.760 look, there's there's coolant terminals on the outside. Yeah. And you can water 00:18:31.520 --> 00:18:37.360 cool them. And realistically, if you're doing an EV conversion, you really would 00:18:35.600 --> 00:18:42.720 want to water cool them, but we could hook it up to the pool. Yeah, you could. 00:18:40.400 --> 00:18:48.160 We're pulling from the grid, charging 2900 watts, and then we are consuming 00:18:45.919 --> 00:18:51.160 2,000 watts all at the same time. Let's just try it. Okay. Okay. So, we're just 00:18:49.520 --> 00:18:56.960 going to unplug the wall. Okay. I heard a beep. Oh, 00:18:53.360 --> 00:18:59.320 everything's bad. It's bad. Oh, come on. 00:18:56.960 --> 00:19:06.400 46 amps. 48 45. She goes. That simple. Let's 00:19:03.799 --> 00:19:12.000 go. In conclusion, this is kind of awesome. Not that crazy. Right now, all 00:19:08.559 --> 00:19:13.679 we need to do is 10x it. Yeah, a 200 kWh 00:19:12.000 --> 00:19:19.200 battery would be freaking sick. But where do we put it? I'm thinking this 00:19:15.440 --> 00:19:22.000 goes. Yeah. And we basically just build 00:19:19.200 --> 00:19:25.520 a giant battery wall. Like I could put this bench on wheels, put it over here 00:19:24.160 --> 00:19:29.919 in front of all this stuff, and then if I ever need to access this, I just wheel it away. Yeah. Or I could just not do 00:19:28.640 --> 00:19:34.640 this in here, and I could just use my garage like a normal person. Or this could just sit in front of the 00:19:32.480 --> 00:19:40.080 batteries. Or we could just segue to our sponsor, War Thunder. Take to the skies, 00:19:37.840 --> 00:19:44.320 strike from the sea, and dominate on land. With War Thunder's thousands of 00:19:42.160 --> 00:19:47.840 vehicles, each modeled accurately from their real life counterparts.

If you guys enjoyed this video, uh maybe go check out the one 00:20:32.000 --> 00:20:36.720 that we did on putting the solar panels on the roof. They're really cool panels. 00:20:35.520 --> 00:20:42.240 It just turns out they're not quite compatible with this application cuz I told them not to have ones like that. 00:20:40.720 --> 00:20:47.200 Yeah, making this work for the whole house and the solar is going to be 00:20:44.880 --> 00:20:47.200 interesting.
