  "textContent": "A battery system for a motor vehicle or other system includes a voltage bus with positive and negative bus rails, and first and second battery packs. The battery packs are arranged between and connected to rails. High-voltage switches are collectively configured to selectively interconnect the battery packs in a series or parallel battery arrangement. The switches include a pair of mutually-exclusive three-way/two-position contactors each having a series connection position and parallel connection position corresponding to the respective series and parallel battery arrangements. An electric powertrain includes an electrical load connected to the battery system, and a controller coupled to the switches. In response to a battery mode selection signal, the controller selectively transitions the contactors from the series connection position to the parallel connection position, or vice versa. A motor vehicle includes road wheels, a body, and the electric powertrain.",
