Micro Fission Battery

The Micro Fission Battery is named somewhat incorrectly. As it contains a functioning reactor with its own source of radioactive materials it's really more of a reactor. However due to its small size and (relatively) short run time it is classified as a battery. It is capable of outputting up to 1100 volts, though at this output its run tim is just 200 hours. At its standard voltage of 220v it can run under load for 4,500 hours. The only major downside to the battery is its high handling risk. While it is shielded its small size (roughly that of a football) prevents it from housing enough shielding to protect operators, as a result trained engineers in rad-suits are needed for handling.
