Dragonfly Energy & Airstream Expand Partnership

It was recently announced that Dragonfly Energy’s Battle Born Batteries® are now the lithium battery option for all Airstream products. This is a really interesting development because batteries in motorized and towable recreational vehicles provide electricity for running onboard lights and appliances without needing to be constantly plugged into grid electricity. Having the ability to go off-grid for a time is exactly what some RVers want. There are also RV owners who want to utilize solar panels to generate their own electricity to charge their onboard battery systems.

Additionally, there are some customers who live in their RVs so they have a tiny home on wheels. Batteries power their refrigerator and freezer combos, cookstop stoves, lights, AC/heat, laptops, wifi, and so on. When combined with their own solar power systems, they can charge their batteries and not have to use electricity from a utility.

Tyler Bourns, Chief Marketing Officer at Dragonfly Energy, answered some questions about their expanded partnership with Airstream.

Which Airstream products will have Dragonfly Energy’s Battle Born Batteries?

Dragonfly Energy’s Battle Born® LiFePO₄ batteries have powered Airstream products for many years, and we’re proud to now be featured across their entire lineup. Beginning with the 2026 model year, our batteries are standard in Airstream’s Interstate and Atlas motorized lines, seamlessly integrated into both the Advanced Power System and the Advanced Power Plus Packages. Beyond that, Battle Born Batteries are available across all Airstream products, whether as standard equipment or as an optional upgrade. 

What is the battery chemistry?

Our batteries use lithium iron phosphate (LiFePO₄), which is widely recognized as the safest chemistry for energy storage. Unlike other lithium chemistries, LiFePO₄ is highly stable, nontoxic, and far less prone to thermal runaway, making it ideal for mobile and residential applications. We take safety one step further by engineering our packs with cylindrical cells, which are inherently more robust and resistant to mechanical stress. That design choice not only improves reliability but also gives our customers confidence that their families are safe, even when they’re literally sleeping right on top of the batteries in an RV or trailer.

All of our batteries are assembled in our 400,000-square-foot facility in Reno, Nevada, where we combine advanced engineering with rigorous quality control to ensure consistency and safety at scale. From a performance standpoint, our LiFePO₄ batteries deliver 3,000–5,000 cycles at 100% depth of discharge, meaning they last significantly longer than traditional lead-acid options while providing more than twice the usable power in the same footprint.

What is the warranty?

Every Battle Born Battery is backed by a 10-year warranty; we build them to last, and we stand behind them.

What are the battery capacities? 

We currently offer batteries ranging from 75 Ah up to 270 Ah, serving applications in the 12-volt to 48-volt range. Many of our models are available with optional integrated heating technology, ensuring reliable performance even in colder climates.

In Airstream’s lineup specifically, our Battle Born Batteries are factory-installed within the Advanced Power System and Advanced Power Plus Packages on the Interstate and Atlas motorized products. At the heart of these packages is the High-Capacity System, featuring three of our patented BBGC3H LiFePO₄ batteries, which deliver 10.3 kWh of usable energy at 100% depth of discharge. For those who need even more power, Airstream Interstate and Atlas 2026 models can be upgraded to the Advanced Power Plus system, allowing customers to add up to two additional BBGC3 batteries (an extra 6.9 kWh) either at the factory or through an authorized Airstream dealer.

Other Airstream towable units feature our BBGC3H and BBGC2H products, giving customers dependable lithium power options across the brand. These integrations provide long service life, safety, and confidence wherever Airstream owners’ travel.

Do the batteries have thermal management, including for cold weather? 

Yes. All of our models are available with optional integrated heating technology inside, which provides internal thermal heating to allow for safe charging and discharging even in cold weather. Every Battle Born Battery also includes an advanced Battery Management System (BMS) with low-temperature protection, which prevents charging in conditions that are too cold, ensuring the cells are never damaged. Together, these safeguards deliver safe, reliable power year-round and give customers confidence in their systems no matter the climate.

What is the price range for the batteries? 

Our batteries start at $799 for our most popular model, the BB10012 (100 Ah 12V Deep Cycle), and go up to $2,299 for our largest battery, the BBGC3 (270 Ah 12V Deep Cycle). Customers can also choose additional options, such as integrated heating or Dragonfly IntelLigence® wireless communication, for an added cost.

Are the batteries compatible with solar power or a small wind turbine? 

Yes. Our Battle Born Batteries are a perfect match for solar power systems, and we firmly believe a battery bank should be considered a required part of any solar installation, so you can store the energy you capture and use it when you need it most. Our batteries also pair with small wind turbines, and while some of our off-grid customers experiment with them, wind generation is less common due to the relatively low energy produced compared to the turbine size. In both cases, our LiFePO₄ batteries provide safe, reliable storage that makes renewable energy truly usable.

About how much do the batteries weigh? 

Our batteries are significantly lighter than traditional lead-acid — nearly one-third the weight in the same form factor. Depending on the model, our packs range from about 31 pounds for a 100 Ah battery up to around 80 pounds for our largest 270 Ah battery.
