Recreational Vehicle Power Solutions
Factory-installed by leading RV manufacturers across North America
Reliable Power for Everyday RV Living
RV travel has changed. Residential refrigerators, inverters, and connected devices now depend on reliable onboard power.
Battle Born RV power systems are built around LiFePO4 batteries designed to support modern RV electrical needs. Whether you are traveling between destinations, staying at a campground, or spending time away from hookups, your power system should work without constant monitoring.
This isn’t about adding more power. It’s about removing limitations.
Built for How You Camp
Battle Born lithium systems are designed for real-world RV electrical use.
Stay Longer
Full usable capacity means you get the energy you paid for.
Recharge Faster
From solar, alternator, or shore power, lithium accepts charge quickly so you spend less time waiting.
Deliver Stable Power
No voltage sag. Appliances run consistently until the battery is empty.
No Generator Dependence
More silent mornings. More peaceful nights.
Designed for Longevity
Built for years of reliable use in demanding mobile environments.
Choose the Right Battery Power Technology
RVers Know Battery Anxiety...
Watching the voltage drop after sunset
Cutting appliance use short
Generator use to avoid dead batteries
Driving all day and still not fully charged
Replacing batteries every season
Traditional lead-acid systems were not designed for modern RV electrical demands. Residential appliances, inverters, solar charging, and connected devices have changed how RVs are used. Your power system should keep up.
How a Battle Born System Powers Your RV
Reliable RV power depends on more than a battery. The components must work together.
Deep Cycle Batteries
Power everyday essentials reliably throughout the day and night.
Smart Batteries
Monitor power remotely, receive alerts, and optimize system health.
Solar Integration
Recharge quietly throughout the day. Extend your stay without fuel or noise.
Alternator Charging
Arrive with power replenished. Drive time is charge time.

400,000+ LiFePO4 Battery Packs In the Field
Trusted by Leading RV Manufacturers
Battle Born Batteries, powered by Dragonfly Energy, are factory-installed by RV manufacturers across North America, where reliability and long-term support matter. As an RV Industry Association (RVIA) member, they meet recognized third-party safety standards for OEM installation. That same manufacturer-trusted quality is available for new RVs and upgrades. Ask your dealer about Battle Born.
American Engineered, Assembled & Supported
Battle Born Batteries are designed, assembled, and supported in the United States at Dragonfly Energy’s headquarters in Reno, Nevada.
Our engineering, testing, and technical support teams work directly with RV manufacturers, dealers, installers, and owners every day. When questions arise, you speak with the people who understand the system, not a call center reading a script.
We stand behind the batteries we build with real technical support and long-term product backing.
Designed for Safe, Reliable RV Power
RV batteries operate inside or directly beneath the living space of the coach and are expected to perform in every season. Safety and predictable operation are essential.
Battle Born Batteries are engineered with safety and predictable operation as core priorities. Each battery contains an internal Battery Management System (BMS) that continuously monitors voltage, current, and temperature. If conditions move outside safe limits, the system automatically disconnects the battery to protect both the battery and the RV electrical system.
Battle Born Batteries have been deployed in hundreds of thousands of RV installations across North America in OEM, dealer, and owner-installed systems, providing dependable everyday power at camp.

Frequently Asked Questions
Do I need to replace my RV converter when upgrading to lithium?
It depends on how your RV charges the batteries.
If your RV uses a converter (common in many trailers and motorhomes):
Lithium batteries require a different charging voltage than lead-acid. Some newer converters already have a lithium mode, while others will still work but may not fully charge the battery. In certain cases, upgrading the converter is recommended for best performance.
If your RV has an inverter/charger:
Many inverter/chargers already support lithium batteries or only require a settings adjustment rather than replacement.
Because RV systems vary by manufacturer and model year, reviewing your charging equipment before upgrading ensures optimal performance.
How long will lithium RV batteries last?
Runtime depends on how much power you use and the size of your battery system.
Lights, fans, water pumps, and electronics use relatively little energy, while appliances like microwaves, coffee makers, and air conditioners use significantly more. Lithium batteries provide full usable capacity and stable voltage, so your appliances continue operating consistently until the battery is depleted.
Because every RV and camping style is different, the best way to estimate runtime is to size the battery system to your actual usage. Our battery calculator can help you estimate how long a system will power your RV based on the appliances you plan to run.
Can I install lithium batteries myself?
Lithium batteries require the charging and electrical system to be configured correctly in order to perform properly. RV wiring, charging equipment, and alternator behavior vary widely by manufacturer and model year.
For this reason, Battle Born recommends having the system installed or reviewed by a qualified RV installer familiar with lithium battery systems. A professional installer can verify compatibility, configure charging equipment, and ensure proper protection.
You can locate an experienced installer in your area using our Find an Installer map.
Will lithium batteries work with my solar and alternator charging?
In most cases, yes.
Lithium batteries can charge from shore power, solar, and while driving. However, they charge differently than lead-acid batteries. They accept charge faster and maintain voltage longer, which may require charging settings to be adjusted or an additional component to ensure proper alternator charging.
System compatibility depends on your specific equipment and configuration.
Are lithium batteries safe inside an RV?
Yes. LiFePO4 (lithium iron phosphate) batteries are a very stable battery chemistry designed for use in mobile environments.
Unlike traditional lead-acid batteries, they do not off-gas during normal operation, do not require exterior venting, and are non-toxic.
Battle Born batteries are built with layered safety protections. An internal Battery Management System (BMS) continuously monitors operation and automatically disconnects the battery if conditions move outside safe limits to protect both the battery and the RV electrical system.
Can I run my air conditioner from batteries?
Yes, with the right system size.
Air conditioners require significantly more power than lights or electronics, so the ability to run AC depends on the number of batteries and the inverter supporting them. Lithium batteries provide stable voltage and high output, making short-term or scheduled AC use possible when the system is properly designed.
Runtime will vary based on the size of your system and how you use it.
