Systems are disclosed for battery modules/systems with cooling systems. In accordance with disclosed embodiments, the cooling system may be disposed against an external surface of a housing of the battery system. The cooling system may utilize air as a coolant to remove heat generated by cells within the battery module, to prevent the cells from aging prematurely. Embodiments of the cooling system may include manifolds, channels, fins, or a combination thereof, which may route the cooling air along the surface of the battery module housing. Such features may create an isothermal temperature distribution within the battery system.
