Designed to operate at C/2 discharge "A 1 megawatt (MW)/2 megawatt-hour (MWh) battery energy system powered by LG Chem batteries", Electrovaya/Litarion provide 9,000 cycles at 1C charge/1C discharge, at C/2 discharge cycling performance should improve vs 1C.

“Energy storage is a technology that can enhance grid reliability and make it easier to integrate renewable energy sources,” said Haresh Kamath, senior program manager at EPRI.
