Military Battery - SciFi and Historical

These are two different takes on a battery game asset—one a retrofuturistic atompunk fusion battery, the other a historical WW2 era nickel accumulator. Each will fit in to its own kind of post-apocalyptic hellscape. The design is inspired by German 2,4NC28 Sammler.

My favorite little detail is that the fuel caps for the fusion battery have two and three slots for the deuterium and tritium fuels respectively.
