AllPowers BS2500 and BS5000: our review of these home storage batteries

Here are two devices that I’ve kept in the back of my mind for a while, because they represent a real turning point for AllPowers, the battery brand we’ve been working with since 2024. Until now, we mainly talked about portable power stations to take anywhere. Now, we’re completely changing direction: the BS2500 and BS5000 are batteries that stay at home, plugged into the grid, to help you during power outages and reduce your electricity bill. Two sizes, one idea, and plenty to say about them.

I’ll be honest with you from the first line, because that’s the rule here: I don’t have these two machines in my hands yet. What follows is therefore an expert opinion based on the technical specifications, visuals provided by the brand, and especially my experience with AllPowers batteries and everything related to energy, from portable to residential.

Let me tell you right away: I think it’s pretty great that AllPowers is getting into residential storage. It’s a brand I’ve liked for a while, with some small advantages that I haven’t always found elsewhere and products that seem well-finished. And above all, the more players there are in this niche, the more competition will push everyone to move and lower prices. This is exactly what has happened with portable batteries in recent years, and that’s good for us.

Before diving into the details model by model, here are the two home storage batteries put side by side, to see right away who targets what.

Two batteries for the home, not for the road

Let’s start by setting the scene, because this is the point that is often misunderstood at first glance. More and more brands that used to make portable batteries are getting into energy storage for the home, simply because the price of cells has dropped and performance has exploded. AllPowers is exactly following this trend with its BS series.

Specifically, these two devices are designed to stay in place and connect to the grid. They play on two fronts: on one side, backup (if the power goes out, they take over), and on the other, smart self-consumption (they store solar energy during the day and release it at the right time to lower the bill). It’s a real energy management system, not just a big battery sitting in the garage.

What I find really practical is the dual use: you can reinject energy into your grid when it suits you, but also plug your most power-hungry devices directly into it. You can feel that the home storage category is becoming increasingly clever, and it’s the kind of flexibility that starts to change the game.

If you’re looking for something to power a fridge in a van or a cooler while camping, this isn’t the place: here, we’re in a different category, that of fixed equipment for housing.

AllPowers BS5000 PRO, the big backup block

The BS5000 PRO is the beefed-up version, the one that plays in the high-capacity backup arena (a segment still quite rare on the market, it should be noted). We’re starting with 5.2 kWh of base capacity, a serious value already, but the real argument is the extension: by chaining up to three units, we climb to 15.6 kWh of total storage. Enough to power an entire house for a good part of the day.

On the technical side, the specs are solid: 2,400 W of output power, two MPPT solar inputs, a semi-solid LFP battery rated for over 6,000 cycles, IP65 certification, and an operating range of -20 to +60 degrees. In other words, you can leave it outside without stress. And the switch to backup mode happens in less than 15 milliseconds, which means that in case of a power outage, your sensitive devices won’t even notice.

First impression from the visuals: I honestly find the device very nice for what it is. We’re more used to seeing storage blocks that come out of a boiler room than this kind of neat finish. The downside is the weight: 65 kg, we’re clearly dealing with equipment that you install once and don’t move again.

AllPowers BS2500 PRO, the accessible entry point

The BS2500 PRO is the little sister, and it’s probably through her that many people will start. Same philosophy of home storage connected to the grid, but in a more affordable format: 2.6 kWh of capacity, expandable to 7.8 kWh by chaining three units. Perfect for an apartment or a small house that wants to start without doing everything at once.

It retains the essential advantages of the larger model: 2,400 W output, dual solar input, IP65, UPS backup under 15 milliseconds, management via the app. The difference on the battery side is a standard LiFePO4 cell rated for up to 15 years of lifespan, while the BS5000 uses semi-solid. Nothing prohibitive, it’s just the logic of a range that is tiered.

The point we won’t hide. At comparable capacity, the BS2500 is reported to be a bit heavier than some competitors (38.8 kg). Personally, that speaks to me directly: I live on the third floor without an elevator, so if I have to carry it up, it might be a bit of hell. But let’s be fair, this is not the kind of device that you move every day, on the contrary: that’s precisely its specificity, a home storage battery is placed once and doesn’t move again. AllPowers embraces this weight and emphasizes robustness, safety, and performance rather than the race for grams. We’ll verify all this in the field test.

Finishes, app, and connection to the grid

This is perhaps where the BS series surprised me the most on paper. AllPowers has completely redesigned its mobile app, with a real focus on control and fine management of energy. On this type of product, the app does half the work: it decides when to store, when to release, how much to inject into the grid. A good interface is not a gadget, it’s what transforms a battery into a real source of savings.

Another thing that reveals equipment designed to last: the outlets protected by a silicone cover. It’s a trivial detail, but it’s typically the kind of small advantage I appreciate at AllPowers and don’t always find elsewhere, exactly the kind of finish you only see on equipment designed for real use, outdoors, over the years. The overall finishes exude seriousness, closer to professional than to consumer gadget.

On the space front, I also find the format quite successful: these batteries are tall and rather slim, so they don’t stick out in an interior. You can fit them against a wall without the feeling of installing a construction meter in the middle of the living room, and that matters when a device is meant to stay there permanently.

For whom, and for what uses?

The question to ask is not really BS2500 or BS5000, but rather: in which scenario do I see myself? Because these batteries meet three concrete needs, often all three at once.

Securing against power outages. Backup against outages is clearly the number one use in my eyes. If you work from home, a power cut at the wrong moment can be costly, and the automatic switch does exactly that job without you having to think about it.

I also see more and more of these kinds of devices installed in garages, to give a boost to charging a car. Let’s be honest, 5 kWh won’t fill a car battery on its own, but as a supplement, it can be very nice. And of course, there’s all the interest in areas poorly served by the grid, where a power outage is not uncommon. On paper, AllPowers checks the right boxes for the category (grid connection, smart management, expandability), and it honestly makes me want to plug it all in for real. We had already had good surprises testing a portable Aferiy battery, so I’m curious to see what the brand delivers on fixed.

Our provisional verdict

On paper, the overall impression is frankly positive. AllPowers is entering the home storage market with a coherent and well-thought-out range: the BS2500 to start without breaking the bank, the BS5000 for a real backup system at home, and an expandability that allows the installation to grow over time.
