Expion360 Inc. (Nasdaq: XPON), a leader in lithium-ion battery power storage solutions, has announced a strategic partnership with Dealer Accessory Supply (DAS)—marking the company’s official entry into the industrial market with the launch of the DASGen Hybrid Energy Storage System.
Built for construction and industrial job sites, DASGen introduces a new approach to powering equipment by combining diesel generation with advanced lithium-based energy storage. The system is designed to help job sites reduce generator runtime, improve efficiency, and lower operating costs—while maintaining reliable power delivery.
A Hybrid System Designed to Optimize Generator Performance
At the core of DASGen is Expion360’s lithium iron phosphate (LiFePO4) battery technology, integrated into DAS’s hybrid system architecture. The system functions as an energy buffer between a diesel generator and jobsite electrical loads.
Instead of running continuously, the generator can operate more strategically—charging the battery system and then powering loads through stored energy as demand fluctuates. This design aims to allow generators to run fewer hours and at higher efficiency, depending on site conditions and usage patterns.
“This partnership highlights Expion360’s entry into the industrial space, which has been one of our strategic targets for expanding into adjacent verticals,” said Carson Heagen, Chief Operating Officer of Expion360. “DASGen is designed to address generator utilization challenges commonly observed on construction sites.”
Key Operational Goals of DASGen
While results may vary based on jobsite conditions and load profiles, DASGen is intended to support several important performance improvements:
-
Reduced diesel consumption through optimized generator runtime
-
Lower operating and maintenance costs by reducing wear on generators
-
Reduced noise levels by limiting runtime during low-demand periods
-
Lower emissions compared to continuous generator operation
-
Improved cost predictability by reducing dependence on fluctuating diesel prices
DASGen combines Expion360’s lithium energy storage platform with advanced industrial power electronics to deliver these benefits.
Field Deployment Shows Promising Results
Expion360 highlighted a recent illustrative deployment of DASGen at a construction site operating a 25kW diesel generator. Prior to installation, the generator reportedly ran continuously across multiple shifts. After DASGen was introduced, customer-provided data showed generator runtime decreased during the evaluation period.
According to the same data, the reduced runtime resulted in lower diesel fuel consumption compared to previous operating practices. The company noted that real-world results depend on site-specific factors including load profiles, operating schedules, and fuel pricing.
Industry Excitement and Nationwide Expansion Plans
DAS leadership expressed strong confidence in both the system’s performance and market demand.
“Developed through collaborative engineering and a shared vision, the DASGen has exceeded our expectations,” said Ty McIntosh, CEO of Dealer Accessory Supply. “We are thrilled with both the results from our test-site performance and the interest from leading construction firms.”
McIntosh added that DAS and Expion360 are preparing for wider deployment and anticipate DASGen systems operating on job sites across the country.
Partnership Roles: Assembly, Battery Supply, and Sales
Under the partnership agreement:
-
Dealer Accessory Supply will serve as the final system assembler, handling integrated system assembly and delivery.
-
Expion360 will supply the battery technology and lead sales and marketing through its commercial sales organization.
