A battery system includes a battery assembly and an equipment interface. The battery assembly includes a battery pack, a battery housing enclosing the battery pack, a communication gateway, and a first electrical connector. The battery pack includes rechargeable battery cells. The communication gateway is configured to communicate using a first communication protocol and a second communication protocol different from the first communication protocol. The first electrical connector includes a plurality of first terminals. The equipment interface is configured to be coupled to a piece of equipment, and includes a second electrical connector including a plurality of second terminals. The second electrical connector is configured to mate with the first electrical connector to electrically coupled the plurality of first terminals with the plurality of second terminals to electrically couple the battery assembly to the equipment interface.

Battery system for power equipment

A battery pack for selectively providing electrical power to power equipment includes a housing, a plurality of rechargeable lithium-ion battery cells, and a printed circuit board. The housing defines an internal cavity and an external terminal connection. The external terminal connection includes a plurality of high voltage connection pins and a plurality of low voltage connection pins. The plurality of rechargeable lithium-ion battery cells are received within the internal cavity and are configured to supply electrically power through the external terminal connection to the power equipment. The printed circuit board is received within the housing and includes a controller and a transceiver. The transceiver includes a near-field communication chip in communication with the controller. The near-field communication chip is configured to detect a near-field communication tag on power equipment and communicate information from the near-field communication tag to the controller.

Battery pack for selectively providing electrical power to power equipment

A starting circuit for providing electric power to a starter motor of an internal combustion engine of outdoor power equipment is shown and described. The starting circuit includes a battery receptacle mounted on the outdoor power equipment and a starter battery that is received within the battery receptacle. The starter battery includes a battery controller and a series of battery cells contained within an outer housing. A plurality of high current pins provide electric power to the starter motor and auxiliary devices on the tractor/mower while a plurality of low current pins receives signals from the tractor/mower related to operation of the tractor/mower. A wireless transceiver is used to communicate information from the battery controller to a wireless device. The wireless device displays the received information to a user. The battery receptacle can be configured to include a dipstick receiver that receives an oil dipstick.
