ONE’s core battery technologies include the Aries9 LFP battery pack (79 kWh, >200-mile range), the Aries9 II (100+ kWh, >350-mile range, nickel- and cobalt-free), the Gemini9 dual-chemistry battery (185+ kWh, up to 608-mile range in a BMW iX), and the Aries9 Grid utility energy storage system. These cells are produced at the ONE Circle Gigafactory, which can yield enough cells for 240,000 Aries II and Gemini packs annually.
