US battery manufacturer Lyten has raised over $200 million in equity financing to support its expansion into European battery energy storage systems (BESS). The company is acquiring Northvolt’s former energy storage product line, including the Voltpack Mobile System (VMS), Voltrack, and other assets, as it moves to ramp up manufacturing in Poland and widen its commercial prospects. This marks Lyten’s third transaction related to Northvolt assets since November 2024. Under the agreement, core members of Northvolt’s energy storage engineering team will join Lyten’s Stockholm office, and production of VMS and forthcoming BESS products will take place at the Gdansk facility in Poland.

The announcement follows Lyten’s previously reported acquisition of Northvolt Dwa, a 6 GWh BESS facility in Gdansk. That plant is expected to restart operations in the second half of 2025, with initial deliveries slated for Q4. The facility was idled earlier this year but will initially resume production using nickel-based cells already in stock. Lyten ultimately plans to convert it to produce its proprietary lithium-sulfur cells, which moves supply chain requirements away from China.

As reported, the company also fired around 45 employees in the previous week, including Celina Mikolajczak, an experienced Tesla employee who was part of the push to commercialize Lyten’s proprietary lithium-sulfur battery cells. The company didn’t comment.

The acquisition of Northvolt’s BESS IP and factory is expected to close in Q3. Lyten’s backers include Stellantis, FedEx, Prime Movers Lab, and the Luxembourg Future Fund. No details were provided on how much Lyten is paying for Northvolt’s IP or the Poland plant.

Lyten previously announced two related acquisitions: Northvolt’s Cuberg battery manufacturing plant in San Leandro, California, in November 2024, and plans to acquire Northvolt Dwa—touted as Europe’s largest BESS manufacturing site—in Gdansk, Poland. Upon closing the Northvolt Dwa transaction, Lyten intends to resume BESS production in Gdansk immediately and aims to begin delivering systems by the fourth quarter of 2025. Initial deliveries will focus on existing European customers, followed by broader distribution to markets including AI data centers, industrial and commercial users, and utility-scale grid applications.

Lyten, founded in 2015 and headquartered in San Jose, California, with European offices in Luxembourg and Stockholm, holds more than 540 patents and is currently manufacturing in San Jose. The company’s proprietary Lyten 3D Graphene platform underpins its lithium-sulfur batteries and other decarbonizing technologies.
