Factorial has deals with several automakers, including but not limited to Stellantis, which plans to do a test fleet of Dodge Chargers in 2026 followed by actual production somewhere between 2028 and 2032.

The version to be tested provide 375 watt-hours per kilogram, and can be recharged from 15% to 90% in 18 minutes. They should provide longer life than traditional lithium batteries.

Recently, Factorial’s FEST batteries, another alternative technology, passed validation testing as well.
