The Moskva-2020 trainsets which Transmashholding company Metrowagonmash is supplying for the Moscow Metro are being fitted with this system made by French battery manufacturer SAFT, as railway magazine «Railway Supply» reports referring to Railway Gazette.

SAFT said the MSX cells designed and manufactured at its Bordeaux factory are up to 30% lighter and 40% smaller than conventional onboard backup batteries, and can operate at temperatures down to -40°C to cope with winter conditions on surface sections of the network.

SAFT is a French industrial company that develops and manufactures lithium batteries and batteries for industrial, military and space applications. The headquarters are located in Bagnolet, France. SAFT was one of the first in the development and production of lithium cells and lithium-ion batteries.
