using batteries as armor on electric combat vehicles

using batteries as armor on electric combat vehicles would make use of the weight that armor entails 

there are lots of battery technologies currently available that could function as armor, only problem would be overheating from sunlight, but there are materials that could absorb and distibute sunlight

thick carbon fiber batteries would be sufficient armor 

thick graphene batteries would be efficient armor 

electric combat vehicles with sufficient energy storage in it's battery armor could have enough power to use energy weapons against drones and missiles 

hypothetically electric combat vehicles could have receivers to recharge batteries by airborne or spaceborne energy transfer systems if weather allows
