The F6 DM uses ferrous batteries, with no lithium content, that BYD says are high-energy density and low cost. Some experts predict that such a battery - or a similar battery - could be production-ready by 2010 to 2012.Larry BYD also developed the motors and software for the system. GM Press Release ).
