An enclosure includes a housing defining an interior chamber for receiving an electronic assembly. The housing is made of a thermally conductive material so as to operate as a heat sink. The housing has a heat transfer surface within the interior chamber for receiving heat generating components thereon, and an interior groove within the interior chamber. The enclosure also includes a retaining clip having a clip length, a first portion extending along the clip length for engaging the interior groove, and a second portion extending along the clip length for engaging the heat generating components. The retaining clip is made from a resilient material and is sized and shaped such that positioning the first portion in the interior groove flexes the retaining clip and presses the second portion against the heat generating components so as to bias the heat generating components into thermal contact with the heat transfer surface.

A vehicle such as a riding lawn mower may have at least one electric drive motor configured to drive at least one wheel, at least one electric blade motor configured to drive at least one cutting blade, and a battery module connected to the drive and blade motors. According to some embodiments, a method of controlling the vehicle may include: operating the blade motor according to a blade target speed; monitoring a blade current load for the blade motor; comparing the blade current load to a light load low threshold for the blade motor; and if the blade current load is less than the light load low threshold, decreasing the blade target speed.
