Torus (South Salt Lake, UT) leads Ultion Technologies' (Las Vegas, NV) Series A to scale U.S.-made LFP battery production, strengthening domestic energy storage resilience and reducing dependence on foreign supply chains.
South Salt Lake, Utah - July 15, 2025
Torus, a leader in full-stack energy storage and management systems, has led the Series A funding round for Ultion Technologies (Las Vegas), the only U.S.-based company currently shipping advanced lithium iron phosphate (LFP) battery cells and energy storage systems at commercial scale. Terms of the deal were not disclosed.
The round also included participation from mission-aligned partners, notably Nevada’s Battle Born Venture, a state-sponsored venture capital program founded in 2013 and managed by the Governor’s Office of Economic Development (GOED) of Nevada.
This investment marks a critical step in addressing one of the most pressing vulnerabilities in America’s energy infrastructure: the lack of domestic battery production. With over 70% of the world’s battery manufacturing and 90% of battery processing based overseas, the U.S. remains dangerously dependent on foreign supply chains for a technology that underpins grid resilience, energy independence, and national security.
“As both an investor and customer, we understand the risks of depending on overseas battery suppliers,” said Nate Walkingshaw, co-founder and CEO of Torus. “Ultion's proven, domestically produced batteries give us unmatched reliability, shorter lead times and the ability to innovate without international supply chain delays.”
Ultion directly addresses this challenge with a fully integrated U.S. battery manufacturing platform, including a Nevada-based facility that produces advanced LFP batteries from a predominantly domestic supply chain. The Las Vegas-based company plans to move to fully domestic sourcing in the near term. With the Series A funding, Ultion will scale production capacity more than fivefold—delivering more batteries, faster, while creating high-quality American manufacturing jobs.
“Every battery imported from outside the U.S. is a missed opportunity for American jobs and a vulnerability in our energy security,” said Dr. Johnnie Stoker, CEO and founder of Ultion Technologies. “This funding proves not only that American-made batteries can compete with imported batteries in performance and cost — but that our proven cell technology and deep industry expertise position Ultion to lead America’s growing energy storage market.”
Dr. Stoker and Ultion’s founding team bring decades of global experience to the table, having developed and operated lithium battery manufacturing facilities in China, Finland, Ireland, and the U.S. That deep bench of expertise, coupled with a proven domestic product, positions Ultion as a foundational piece of the emerging U.S. battery ecosystem.
Torus’s investment is not just financial—it is deeply strategic. As Torus deploys its smart, resilient mini-power plants across defense, commercial, and critical infrastructure sectors, access to a stable, high-quality U.S. battery supply chain becomes a differentiator. The alignment between Torus’s platform and Ultion’s production capabilities ensures that innovation won’t be bottlenecked by global instability or foreign dependencies.
Wood Mackenzie forecasts over $1.2 trillion in global battery energy storage investments by 2034 to support the transition to grid-forming renewables. Without a rapid expansion of U.S. battery manufacturing, most of that economic value will be exported. Torus and Ultion are committed to reversing that trend.
Ultion is not just a battery company—it’s a national capability. As Walkingshaw noted: “Ultion’s proven, domestically produced batteries give us unmatched reliability, shorter lead times and the ability to innovate without international supply chain delays.”
