Abstract
A scalable power unit for powering one or more electric motors of a riding vehicle and/or a piece of outdoor power equipment includes a number of interconnected battery packs. The battery pack are received in a battery tray or stacked to form the scalable power unit. Each battery pack is configured to be removed and used separately or added to a combination of battery packs. A control unit selectively opens and closes switching elements to separately control the connections between the battery packs and an electrical load, such as a motor. During charging, the control unit opens and closes switching elements to control the charging rate of the individual battery packs. When the battery packs are connected to an electrical load, the control unit controls the state of the switching elements to selectively discharge the battery packs to power the riding vehicle and/or electric loads.
