Construction of batteries allows to provide capacity from 50 to 200 kWh, and charging is possible at a power up to 200 Watts. The platform for trucks and commercial cars supports charging at 800 V and at a power up to 350 Watts.

Cobalt amount in accumulators is reduced approximately by 70% in comparison with the competing solutions — instead of this metal cheaper aluminum is applied. Experts believe that it will allow to reduce the cost of rechargeable batteries for electric vehicles approximately by 45%.

New development already found application in the pilotless electric vehicle Cruise Origin which was provided in January, 2020. During the 2020th  Hummer Cadillac Lyriq and GMC electrical machines which will work for Ultium intend to release the American producer.

Rechargeable batteries in this platform are installed under passenger salon for providing lower center of gravity that improves general management and allows to add more space in salon.
