Additionally, a battery container is provided comprising a base for holding the battery, the base having a floor and upwardly extending sides for part of the height of the battery; and a cover for the container having a top and sides extending downward to meet the upwardly extending sides, the cover and the base having mating seals to form a substantially airtight container. An air scoop is provided, oriented to accept cooling air when the vehicle is in motion.
