Gizmodo.com: At over 60 feet in length the BYD Lancaster eBus uses an articulated dual-body design to maximise rider capacity, but even when full BYD Motors promises the electric bus can travel over 170 miles on a single charge. To ensure the technology on board is safe for the public, the eBus uses the company's iron-phosphate batteries which are fire-safe, recyclable, and can be recharged in about two to four hours. And since the buses would be charged overnight during off-peak energy hours, a whole fleet can be recharged without requiring an increase in power to a local power grid.
