Expanded Footprint Underscores Industry Confidence in Expion360's Certified, High-Performance Lithium Battery Technology
REDMOND, Ore., May 19, 2026 (GLOBE NEWSWIRE) -- Expion360 Inc. (NASDAQ:XPON) ("Expion360"), an industry leader in lithium-ion battery power storage solutions, today announced the continued expansion of its presence within Forest River, Inc. ("Forest River"), one of the largest and most respected manufacturers in the RV industry. Building on an established and growing relationship that already spans its Dynamax and East to West product lines, Forest River has selected Expion360 batteries for integration into two additional motorized brands: Georgetown and Dynamax Grand Sport. The selection underscores the confidence Forest River has in Expion360's technology and their ability to meet the safety, performance, and reliability standards expected by premium motorized RV customers.
A Relationship Built on Performance
Expion360's presence within Forest River is the result of a relationship built on consistent performance and a shared commitment to delivering quality to the end customer. Expion360 has been supplying Dynamax, Forest River's premium Class C motorized brand, with lithium battery systems and has established a proven track record within Forest River's East to West division as well. At the center of the Dynamax relationship is Expion360's 12V 240Ah Edge battery, a high-capacity lithium iron phosphate (LiFePO4) solution that has become the dominant power platform across Dynamax units and a testament to the reliability Expion360 brings to demanding motorized applications. A foundation of real-world performance across multiple product lines paved the way for Forest River's decision to extend the Expion360 platform into Georgetown and Dynamax Grand Sport, two of its most-recognized motorized offerings. For Expion360, the expansion represents a validation of what its engineering and operations teams have been building toward, and a meaningful step in its original equipment manufacturer ("OEM") strategy within the motorized RV segment.
Engineering and Certification That OEM Partners Can Stand Behind
Central to Expion360's OEM value proposition is a commitment to third-party certified safety and proprietary technology that goes beyond standard lithium battery offerings. Expion360's battery packs carry UL1973 certification, the recognized benchmark for batteries used in stationary, vehicle, and mobile applications. Achieving UL1973 requires rigorous independent testing across electrical, mechanical, and environmental abuse conditions, giving OEM manufacturers and end customers alike the confidence that every unit shipped has met an independently verified safety standard.
The same engineering discipline extends to thermal performance. Expion360's proprietary Vertical Heat Conduction technology delivers uniform heat distribution at the individual cell level, ensuring reliable performance in cold-weather conditions where conventional lithium batteries can fall short. Combined with UL1973-certified safety validation, in-house engineering, a build standard designed to handle the vibration, thermal cycling, and sustained power demands of motorized RV applications, Expion360 delivers a battery platform that Forest River can confidently stand behind.
