The set of walls extending from the bottom of the tray and defining a cavity within the tray. A cover removably attached to the plurality of walls of said tray opposite the bottom of said tray. Energy absorption components attached to the bottom of the tray external to at least one of the set of walls in some versions to enhance impact resistance. The construct has high strength, is light weight and well suited for containing and protecting energy cells or batteries that adjusted to impact resistance, fire resistance, and fluid penetration prevention. ## Claims ### Claim 1 A battery containment construct comprising: a unitary tray having a bottom and a plurality of walls including a first side wall, a second side wall, a first end wall, and a second end wall, the plurality of walls extending from the bottom of said tray and defining a cavity within said tray;
