In October 2015, General Motors revealed that they are purchasing the Bolt's batteries at a price of $145 per kilowatt hour from LG Chem, reportedly about $100 cheaper per kWh than the price LG was giving other customers at the time.[5][6]

GM says that the "nickel-rich lithium-ion" battery chemistry allows the cells in the Bolt to run at higher temperatures than the ones used in other cars. This helps reduce the cost of the vehicle since this allows a simpler and cheaper cooling system for the 60 kWh battery pack. The battery pack weights 960 pounds (440 kg) and is composed of 288 flat "landscape" format cells (similar in shape to cells used in other GM products, but in contrast to the cylindrical 18650 cells used by Tesla). Cells are bundled into a groups of three, and there are 96 groups across the pack.[7]

Other specifications include a 200 hp (150 kW) and 266 lb·ft (361 N·m) electric motor, acceleration from 0-30 mph in 2.9 seconds and 0-60 mph in less than 7 seconds, top speed of 91 mph, and SAE Combo DC fast charging that can add 90 miles of range in 30 minutes or fill the battery to 80% capacity in an hour. The motor drive unit includes an Electronic Precision Shift system, which appears to refer to a small automatic transmission with multiple speeds to allow the motor to operate more efficiently than if it was a direct-drive with only a single fixed gear ratio. The number of available gears was not disclosed, but Chevrolet reports a final drive ratio of 7.05:1.[8][9]
