BLUETTI Expansion Battery: Go Beyond for Capacity Boost – Complete Power Sources Alone


If you own a power station, you’re probably familiar with expansion batteries. Many brands today offer modular power storage solutions, which usually include power generators and additional battery packs for flexible capacities. These battery modules, known as “expansion batteries”, allow you to expand the capacity of your power station to your needs.

In this article, we will delve into the world of expansion batteries from BLUETTI, one of the top players in this field. BLUETTI provides diverse extra battery models with capacities ranging from 806 Wh to 3,072 Wh. What sets BLUETTI apart from its competitors is that its battery packs increase capacity and function as standalone power sources.

BLUETTI Expansion Battery Features

Wide Compatibility: Extending the Power of BLUETTI’s Power Stations

BLUETTI expansion battery series, including the B230, B300, B300S, and B80, are compatible with a range of BLUETTI generator models, allowing you to upgrade your energy storage at a minimal cost. By connecting an expansion battery to your existing power station, you’ll get extended runtime without sacrificing portability.

Reliable LiFePO4 Battery Cells: Safe Power That Lasts

BLUETTI expansion batteries use safe and reliable LiFePO4 battery cells for an impressive lifespan of 3,000 to 3,500 cycles to 80%, equivalent to approximately 10 years of daily use with a discharge per day. Additionally, these batteries adopt a proprietary Battery Management System (BMS) that protects them from overcharging, short circuits, and other potential safety risks.

Complete Power Bank with Multiple Outputs and Charging Methods

More than complements for power stations, BLUETTI expansion batteries also serve as complete power banks with power buttons, indicators, multiple inputs, and outputs. You can directly plug your devices into their three outlets: a 100 W USB-C port, an 18 W USB-A port, and a 12V / 10A cigarette lighter port. For recharging, they accept AC adapters, solar panels, car outlets, or even lead-acid batteries. Some models even support dual fast charging.

Extended Runtime for Camping with Family

If you’re planning a family outing with an AC60, consider adding a few B80 battery packs for more power in the wild. Aside from its ability to boost the 403 Wh AC60 to a maximum of 2,015 Wh, the 806 Wh B80 alone can charge a smartphone 43 times, a laptop 10 times, and power a light for over 60 hours. Plus, the compact B80 has a folding handle and IP65 rating, so you can easily take it anywhere for beach parties, boating, and more.

For glamping or road trips, you’ll want the B230 to complement your AC200MAX. Stack one or two battery packs on top of the generator and you’ll get a whopping 6,144 Wh for all those power guzzlers like electric grills and kettles. Since the battery has its own outlets, your tablets, phones, and portables can be powered directly from it. One user reviews a B230 saying that this “2,000 Wh battery can run my 12V fridge about 4 days.

More Backup Power for Prolonged Power Outages

Some of you may encounter this situation: the mid-range power station in your home can’t meet the growing demand for electricity during blackouts, and a new high-capacity one could cost a bank. BLUETT offers budget options: 3,072 Wh B300 and B300S. The main difference between the two is that the B300S has a self-heating function to remain responsive even at temperatures as low as -20°C. A great treat for those living in cold climates or embarking on extreme adventures.

The modular AC300 could top out at 12,288 Wh with four B300 or B300S packs, while the AC500 supports four B300 or six B300S for an impressive 18,432 Wh, enough to power an average 3k Wh home for almost a week. These battery packs simply give you more juice to run your refrigerators, TVs, kitchen appliances, and other essentials to comfortably survive an extra-long power outage.
