Aries I delivers 150 miles of range on a single charge without nickel and cobalt. Using lithium iron phosphate (LFP) chemistry and innovative design, Aries I offers procurement managers compact power that is safe, durable and scalable. It delivers 3,000 cycles and allows daily charging up to 100% without degradation. And Aries I is built with abundant raw materials, so global supply issues are unlikely to slow production.
Already in production.
Aries I is produced in Michigan for ONE by Piston Automotive on a dedicated product line.
More miles, less space.
By using LFP chemistry, Aries I makes larger cells possible while taking advantage of structural housings for load transfer. With more range and greater efficiency, Aries I unlocks thousands of new routes for emission-free fleets.

Sustainable supply.
Nickel and cobalt are expensive, and prices can fluctuate wildly. Aries I uses LFP chemistry, so it’s safer, lower in cost and made from more abundant materials like iron.

Cell–to–pack energy density.
Structural Cell-to-Pack™ architecture allows 76% system-level energy density in a compact format.
Simply scalable.
Scalable architecture allows for series and parallel configurations. So Aries I can power a wide range of applications, from trucks and boats to homes and grids.
Aries I is road-tested.
In partnership with Motiv, our Aries I LFP pack powered a class 5 truck with a 3-ton payload 150 miles on a single charge.
