SAFTEC manufactures LiFePO4 battery packs for RV builders, battery brands, and other project buyers. We put together this list to help buyers identify companies offering finished lithium batteries for RV house power and compare the questions worth asking before choosing a supplier. SAFTEC appears first because we publish this article; the remaining companies are listed alphabetically.

Home market identifies the company’s base, not the origin of every cell or battery component. Product availability and manufacturing arrangements should be confirmed for the model being purchased.
Who Owns the Brand, and Who Builds the Battery Pack?
“Battery manufacturer” can describe different responsibilities. A company may own the selling brand, design the battery management system, assemble and test the finished pack, manufacture cells, or integrate the pack into a complete RV power system. Those roles should be checked separately.
| Example from this article | Relationship established by company information | What an OEM buyer should still verify |
|---|---|---|
| SAFTEC | The publisher manufactures and customizes finished LiFePO4 battery packs for OEM and project orders. | The agreed cell specification, BMS settings, enclosure, test documents and production acceptance criteria. |
| Dragonfly Energy / Battle Born Batteries | Dragonfly owns the Battle Born brand and describes battery-pack design and assembly at its Reno facility. | Which exact pack and components are proposed for the vehicle program; a Reno pack assembly claim alone does not establish the origin of every cell. |
| Lithionics Battery / Winnebago Industries | Lithionics is a battery-systems business owned by Winnebago Industries. | The battery system’s specifications, integration responsibility and approval route for the intended vehicle. |
How We Selected the Companies
Each company has published information about a finished LiFePO4 battery or battery system intended for RV house power. Its materials also describe a role in battery manufacturing, assembly, or system production. We count Battle Born Batteries together with its parent company, Dragonfly Energy, rather than treating them as two entries.
This scope matters. A cell manufacturer may supply cells used inside an RV battery, but that does not necessarily make it a supplier of finished RV house battery packs. Likewise, an engine starting battery serves a different job from the battery that powers an RV’s appliances.
The Manufacturers
SAFTEC — China (Publisher)
SAFTEC offers RV LiFePO4 battery packs for motorhomes, camper vans, travel trailers, and caravans. Its published reference range includes 12.8V models from 50Ah to 300Ah. For OEM and private-label projects, SAFTEC describes options covering capacity, BMS, enclosure, terminals, communication, heating, labels, and packaging. Buyers can begin with a reference model, then confirm a sample against their vehicle’s electrical and installation requirements.
Battle Born Batteries / Dragonfly Energy — United States
Battle Born is a Dragonfly Energy brand. Its RV range includes finished LiFePO4 deep-cycle batteries, while Dragonfly also works with RV manufacturers on installed power systems. Battle Born states that its batteries are designed, assembled, and supported in Reno, Nevada. Buyers considering this company should distinguish between a standard replacement battery and a battery system specified for a new RV model.
BSLBATT — China
BSLBATT publishes LiFePO4 battery products for recreational vehicles, trailers, and campers, including 12V and 24V options. The company also describes OEM and ODM services. Its range makes it a candidate for buyers who need to discuss battery dimensions and system requirements before selecting a standard or customized pack.
CoPow — China
CoPow publishes an RV lithium battery range with multiple 12V capacities and describes battery pack customization. Its product materials discuss BMS options and features such as monitoring and low-temperature protection. A buyer should request the data sheet and test documents for the exact configuration quoted, since options described across a product range do not necessarily apply to every model.
Expion360 — United States
Expion360 offers LiFePO4 batteries for RV house power and has a dedicated OEM program. Its published range includes Group 27 batteries, with heated options for cold-weather use. The company says it designs and tests its batteries in Oregon, sources cells globally, and oversees final assembly in its domestic facilities. RV builders can ask for drawings, charging guidance, and the documents covering the proposed model.
Lithionics Battery — United States
Lithionics supplies lithium house power systems for RVs and vans and is part of Winnebago Industries. Its materials describe LiFePO4 battery systems, battery management, and integration with vehicle electrical equipment. This makes it relevant to builders evaluating a complete house power architecture as well as a battery module. Buyers should confirm the required voltage, capacity, communication, and service arrangements for their vehicle program.
RELiON Battery — United States
RELiON publishes LiFePO4 batteries specifically for RV house systems, including its InSight 12V range. It also runs a program for RV dealers and installers and describes its battery manufacturing and quality processes. Its published range is useful to examine when a project calls for a defined battery form factor; buyers should still check charging compatibility and installation requirements for the selected model.
ROYPOW — China
ROYPOW manufactures battery and energy storage systems and offers a 48V RV electrical system built around LiFePO4 batteries. Its RV materials cover the battery bank alongside charging and other electrical components. It therefore belongs on a shortlist when the project calls for an integrated higher-voltage house power system, rather than only a conventional 12V replacement battery.
Super B — Netherlands
Super B develops and produces lithium battery systems in the Netherlands. Its Epsilon LiFePO4 range is intended for campers and other mobile applications, with published information on battery management, heating, and communication. Vehicle builders should confirm which Epsilon model fits their installation space and which interfaces their electrical system requires.
What Should an RV Builder Compare Before Choosing a Supplier?
Company names narrow the search. The vehicle specification determines whether a battery will work.
| Question to ask | Why it matters |
|---|---|
| What voltage and usable energy does the RV need? | A 12V replacement and a 48V integrated system solve different design problems. Size the battery against actual loads and expected time off-grid. |
| What are the continuous and peak discharge limits? | The BMS and battery must support the inverter and the loads that may start together. Capacity in Ah alone does not answer this question. |
| How will the battery be charged? | Check the shore-power charger, solar controller, and alternator or DC-DC charging path against the proposed battery’s charging requirements. |
| What happens below freezing? | Ask whether the exact model prevents low-temperature charging, includes heating, and has any special installation or power requirements. |
| Will it fit and communicate with the vehicle? | Confirm dimensions, mounting, terminals, cable routing, and any required monitoring or control interface. |
| Which documents apply to the quoted model? | Request the current data sheet, installation instructions, transport documents, applicable product certifications, warranty terms, and sample test plan. A cell-level document does not automatically certify the finished pack. |
For an OEM project, send every shortlisted supplier the same vehicle brief: system voltage, daily loads, inverter rating, charging sources, battery space, operating climate, required interfaces, estimated annual quantity, and target market. Comparable answers are more useful than comparing marketing claims from different product pages.
Conclusion
These companies represent different routes to RV lithium house power, from standard replacement batteries to customized packs and integrated electrical systems. The right shortlist depends on the vehicle design and the level of engineering support the buyer needs.
If you are developing an RV model or sourcing a private-label battery, send SAFTEC your electrical requirements and target quantity. We can review a reference LiFePO4 pack and the changes needed before sample approval.
