goal in the clean energy space originally was to replace lead-acid, and we think that that's a worthy goal because we think lead-acid is a very damaging thing to have. We would like the federal government to help us with that and make it so that there were no lead-acid batteries in cars, but we may end up getting there at some point. But our current focus is recreational vehicles and expanding into home energy. And we serve our customers through our company's core values, and that's safety, quality, and service. We back it up with what we feel is the best warranty in the industry. That's a 12-year warranty on the battery. Good luck getting 12 years out of a lead- acid battery. I have a boat, and I get one and a half years out of my AGM battery.
By the way, that's a full replacement for the first six years. I apologize for being a little bit slow. This is slightly different than my Mac. Here we go. So again, leveraging our experience in RV and in light electrical vehicle to move into home energy, we're trying to do that by driving the growth adoption and replacement rates as customers move from lead-acid to lithium. We have seen signs that the RV market, which was dead in 2024 or 2023, in the beginning of 2024, is starting to heat back up. How do we know that? Well, first of all, we've seen more of our systems installed in test RVs and test trailers at the RV shows that the dealers attend in Elkhart, Indiana.
You know, the majority of the RVs in the United States are made within 100 miles of Elkhart, and we have seen tremendous interest in those. The dealers are excited. What gets them excited? Well, it's kind of, I call it the second COVID wave. The first COVID wave was everybody needed a trailer or a boat or something to get out. The second COVID wave is the people that might not have been able to afford it because the interest rates have gone up, and they're seeing what their neighbors are doing. They're liking the fact that there may be a trailer in the driveway, and with interest rates coming down, we see more of a demand for that, but typically, interest rates drive demand. We do have some pretty good projections for growth just in the RV market.
If it sounds like I'm rushing a little bit in RV, that's because really the explosive growth in our company over the next couple of years is going to be in home energy. I want to spend as much time on that, but I just want you to know that we have a firm foundation in RV sales, and we do love that industry. However, the potential market for home energy is much, much bigger. Here's the home energy storage market, predicted to be $123 billion globally by 2029. What is driving this? It's the fastest predictive growth of any of the markets that we serve. That's why we're putting our time, energy, and talent into it. It's driven by many factors. Number one of them would be grid instability.
If people want to have a little bit of control over the microgrid at their house, they can do that several ways. Number one, I could protect myself from a brownout or a blackout, kind of like having a power strip with some power in it at my house. The next thing that I could do is protect myself from a blackout that might happen for a day or two. And finally, you could go all the way and give yourself what I call the perfect grid stability, that is off-grid, right? If I don't have to rely on the government bringing me power or the local power companies bringing me power, then I could do off-grid. But what's driving it? Rapidly rising energy costs.
I had a project that I worked on down in the San Francisco area. When we worked on it, they were doing a power purchase agreement at 13.9-cents . We estimated that over the 25 years of the project, that was going to save the school about $500,000 a year in energy. The rates at PG&E have gone from being in the 30% range to the 40% to 50% range. They're now projected to save almost $2.5 million a year, a lot when you're talking about a small school with a small budget. We have California's new Net Metering 3.0 rules. Those Net Metering 3.0 rules say that any new home has to be sold with a solar system and with a battery backup. We feel that is a great market for us.
Finally, we have priced our product, and I'll show that to you in just a minute. We have priced our product in such a manner that it gives the builders and the installers a margin on the battery, something that our competition doesn't always do, right? So we want to be able to bring them in, give them a 10%-25% margin, give them a reason to use our product because money talks, right? I mean, if my product is comparable to somebody else's and the builder can make a 10%-15% margin, it actually gives them two things. Number one, they can make a little bit more money. That's a good incentive. But the other thing is, what if they're going up against somebody else in a bidding war on a project?
I can drop my price 10%-15%, maybe make a little bit less on the Expion360 battery, but go ahead and win that project, so we want to put that tool in the hands of our builders. Just a little bit about our battery technology. In general, lithium iron phosphate has two to three times faster charging, has a higher energy density. It's much lighter. Ours is accessible with a mobile app. It's really neat. If you're one of the golf courses, it might have our GC2 batteries in them to be able to go out into the golf course and into the cart area and be able to see on your phone which carts need to be charged that day and which ones don't, if you're having a problem with the cart, they have an extended lifespan, three to five thousand charging cycles.
That goes back to our warranty. Again, we have a 12-year warranty, six years full replacement. All of our technology related to the lithium iron phosphate batteries is protected by patents. Some of it has to do with the shape of the box. Some of it has to do with the way that these cells are designed, not necessarily the chemistry inside, but the cells themselves. One of the things that we pride ourselves on is the 26650 cell. That's becoming a standard cell for the EV market as well as the RV market. Our cells have 4.5 amp hours, where most of our competition is 3.4. So we can get over 30% more energy density into the same footprint. That's a big deal because in the RV market, in the marine market, and in the home market, footprint is at a premium.
You don't want a battery that's this big in your garage. You'd rather have a battery that's this big in your garage. And we want to be able to put other neat things in there like kayaks and bikes. At least that's the type of thing that's in my garage. Other things related to how we construct our batteries. First of all, IP66 dust and water ingress rated. That means that you're not going to get issues in a marine environment with dust getting in and with water getting in. We try to make sure that the majority of our connections in the battery are bolt-on. There's not a lot of soldering, in fact, almost no soldering. And we design our own and produce our own BMS. That's done with our integration partners, our manufacturing partners in Asia.
We have our own engineering team in Asia that makes sure that the product is tested prior to being shipped to us. We also test when we get here as well. We think that that makes a big difference in the type of product. We're not what I call a lick and stick, meaning I don't just order a battery from someone in Asia and put my sticker on it. Everything is UL 1973 certified, every single one of our batteries. And that just ensures somebody that there's a third party looking out for the safety of the family, whether you're in a boat, whether you're in an RV. And we're doing the same certifications for our home energy product as well. One of our patents pending is on our Vertical Heat Conduction.
If you can imagine, it's very important for a lithium product to have even heating throughout the battery. And in the industry, the solution to that has been to wrap a blanket around the battery. Well, if you can imagine, number one, the battery uses its own power to heat itself. So there's a draw related to that that makes the battery less efficient. The other thing is, if you wrap a battery around something, typically the cells that are in the middle of that battery, they aren't as warm as the cells on the outside, okay, where you need even temperatures. Our batteries are heated from the negative to the positive side of every battery. There's a heating element. It's called vertical heat conduction. And we are working on some third-party testing to prove some of our claims. But in general, we feel that it is superior.
And specifically with our GC2 batteries, which is pictured here, that's a standard battery that goes in a golf cart or that goes into a forklift. It has been very, very well received with the heated element by the industry. Here's our full line of batteries. The one that I would like to draw your attention to are the ones that kind of look like they're on their side with a lot of green. That's our new Edge battery. That battery is 4.2 inches wide. Okay, let that sink in for a moment. That is a new form factor that was not available to the RV industry before we came out with it. It's very solid state. There are very few moving or bolted down parts in that. That allows you to put that battery in the wall of an RV.
You can set it up where it's side to side. You can stack it up, and you can stack it out from a wall. There are many, many different things that you can do, and there's a lot of power there. I mean, the 204 to 240 amp hours and the 12-volt, all of these batteries are UL 1973 certified. I'll probably say this five times in my presentation. Why is that? Because the competition isn't, okay, and our RV associations and people that care about the safety of those that go out in an RV, go out in a trailer, they're starting to care more and more about this because third-party certification to make sure that it operates well when it's hot, it operates well when it's cold, it shuts off when it should.
Furthermore, that it puts out the power that we say that it's going to put out to protect the consumer. We feel that's a big deal. It is a long, expensive process. There's a reason why our batteries is a premium. There's a reason why our batteries cost a little bit more. But we feel that we're starting to win the war. These are our go-to market channels. We have a dealer direct with over 300 dealers. We have distributors, OEMs. We will do a private label as well. So you might see batteries that look like our battery that might be a little bit different color. Depending on whether they want to do a co-brand or not, it might say, "This company powered by Expion360." If that's the case, then we handle all of the service on the battery.
If they want to handle it all themselves, then it would just have their brand name on it. We're in Camping World, Interstate Batteries, Meyer Distributing, and some of the larger RVs, OEMs that we're in include Chinook and Imperial Outdoors. Now to home energy. What's going to be the biggest growth for us? Even though there was a downturn in sales in 2023 of 50% in the RV market, our sales were down 18%. So we feel like we gained market share during that time. But what we knew, what our team knew, is that we had to accelerate the development of our home energy systems during that time just because of the market that it serves. We go from selling $1,000 batteries to $2,000 batteries to selling $30,000 worth of batteries to a customer.
That's a big deal when we're trying to move those 26650 cells in those packs. It helps us with profitability and anytime that I can have somebody touch $30,000 once in a sale versus $1,000 once, it also helps me out with my sales costs, but proper UL certification is vital. If you take a look at our two products that we've developed for the market and the UL certification, I know the screen makes it look like it's got a really fat thing in there, but it's really straight, but so we have two products. Why would we have two products? Okay, we have two products because the solar industry, which kind of drives the home solar energy, which kind of drives the battery backup system, didn't used to all be AC coupled. Okay, it used to be DC.
There are close to three to four million homes in the United States that can be retrofitted with batteries. That's why we came up with the DC coupled expandable server rack style. The one pictured has three 5 kW battery packs in there. You could install that in your house with just one at a cost of around $3,000. That's unheard of. Typically, you're going to probably be installing somewhere between, I think $9,000 is about the cheapest that you'd be able to start with the home energy system. What would that allow me to do? That would allow me to protect against blackouts and brownouts, and if I decided that I wanted a little bit more storage, I could pop in three more of those battery packs, hook up the orange lead wires. It would balance the system.
When the system was balanced, it would tell me that things were ready to go. That one can be expanded up to, it says up to 80 kW. That's in a light industrial application, 40 kW in your home. But we also have the AC coupled one-on-one. Why is this a big deal? This has the inverter inside it. Okay, so it includes an inverter. And one of the things that's important, again, going back to the UL certification, the batteries in these systems have to be certified to UL 1973. The inverter has to be certified to UL 1741, and the entire system has to be certified to UL 9540. Why is that important? Because ROI is important to what I would call a solar or a battery investor, somebody that's going to put that in their house. It's very, very important to them.
Without the 9540 certification, you don't qualify for the tax credits. That's why we do it. Let me talk a little bit about my management team other than myself. Paul Shoun, my COO, is an electrical mechanical engineer. Paul is responsible for the battery designs. We feel privileged to have our own engineering and design department within our company. We feel that's one of the reasons why our batteries are the safest while we have very, very low warranty costs. I don't know that there are very many battery companies that can claim to be publicly traded and to not be required to have a warranty reserve on their books. Okay, we're audited. We are not required to have a warranty reserve because our warranty claims are so low.
Okay, so if a battery comes in and we fix it that month, we write it off that month. I don't have to have a $150,000, $250,000, $300,000 warranty reserve. And Greg Aydelotte Look, we don't miss our filings. If my name's on there, I want to make sure that everything is accurate. I was the CFO prior to becoming the CEO, so I stood in Greg's stead. He was my chief accounting officer, and he's been fantastic. Our company is well positioned with capital. We did a capital raise August 8th, okay, raised $10 million. Part of that requirement was for us to pay off our debt. So other than a loan on a forklift and loan on a vehicle and a small loan from the COVID era, we are debt-free.
The other $5 million, as stated in our filings, went to purchase inventory and go to help us with operations. We are well positioned to cover the demand that our current customers have, not only for RV, which we see that demand going up, but also for home energy. Where are we at as far as our home energy? We have those two products that have been developed and tested within our labs. We have them on our way, and we have an implementation partner that is going to go through the process of making sure that the installation for both on-grid and off-grid when it's connected to the power system to make sure that works well. As soon as we finish up those pilots, then we can start selling into the industry, into the home energy industry.
Typically, that's done through the contractors, which is why we wanted to give such a benefit to the contractor as far as giving them money back, 5%, 10%, 15%, depending 20%, depending on the volume that they buy in. So that's one of the reasons why we're powerfully placed to do well this next year. The other reason is that we have Series A warrants. Okay, we're within a dollar a share right now of being able to have those be exercised. There's $27 million there, and typically, I have found that if the company is doing well related to a stock price, people usually don't care if warrants are being exercised. We see with where our stock has gone since we did our reverse stock split, we've been very, very happy with that. Take a look if you want at Yahoo Finance.
Yahoo Finance, and they build the split in there. Basically, in the last 24 months, our stock has been between $2 and $639. Okay, right now we're at about 4 bucks. We're only $2 above the lowest point that we've been, and it's this management's manager's opinion that we're at the strongest point that we've ever been in the company. Why are we the strongest we've ever been? Well, number one, we've got the capital that we needed to get rid of our debt. We have been working on bringing down our fixed costs. We did a press release stating that we've gone from two warehouses to one warehouse in Redmond. That saved us $40,000 a month, and we have other things that we're working on as well. Okay, we've had a lot of liquidity in the stock.
I mean, I don't know a lot of ultra microcap companies that have traded a billion shares in a day. Okay, we never thought that we would be one, but in the last six weeks or so, you can go take a look at it. We traded over a billion shares on days where people are very excited about us. We're trading 16-20 million shares and 700-900 thousand shares in a day. That's some great liquidity. We think that we are a good investment. We think that we have a bright future, not only with our base in RV, but with what we are going to be doing in home energy. And we did not come here to ask for capital. We came here to ask people to take a look at us as a solid investment for the future.
And we're very thankful that you would meet us here and listen. So I guess we have about three minutes for questions. I'm willing to take any questions. Yes, sir.
So you have batteries for forklifts. And in the past, maybe five years or so, Walmart and Home Depot, they've been transitioning from, I think, lead-acid to hydrogen. So how is it on the cost front comparing hydrogen to now lithium since prices have come down so much on lithium?
On lithium? Yeah, I think that it's comparable. But I think that when you're taking a look at those forklifts, I believe that the biggest issue is how quickly can you get that forklift back on the line when either the battery power has run out or you have to do something to recharge the hydrogen.
One of the things that you've started to see is pre-made packs where the forklift pulls up. I mean, the driver almost doesn't have to get off the forklift, right? It grabs that pack, it pulls it out, puts it on a charging rack, puts a new one in, and they're able to go. I think that that's been a big change in that industry in the past couple of years where before you actually sometimes had to have twice as many forklifts as you did previously because you had four of them charging while there were four of them out on the field. They're starting to get the fast change options for those, and that's exciting. Our GC2 battery is the one that fits into that typical footprint.
Regarding advantages that you have against your competitors, you mentioned safety certification.
Would you say that's your mainstay advantage? Would you have others?
IP as well. We also feel that our warranty, we have what we feel is the best warranty in the industry and 100% replacement up to six years, 12-year warranty. When we did that, a lot of people in the industry choked because they were sitting there with a five or six-year warranty. They kind of had to step up their game. But the fact of the matter is that offering a longer warranty than most of our competition has not hurt us financially. Okay, again, we have very, very low claims related to that. We've never had a recall.
And we just feel that, you know what, if you trust my company to put a battery in your boat or RV that takes a beating and park it outside your house, I'll bet you're going to trust me to put my home energy product in your garage. Good question. All right. Well, thank you so much for coming. Thank you, LD Micro.
