The Polymer Battery Experiment (PBEX) demonstrates the charging and discharging characteristics of polymer batteries in the space environment. PBEX validates use of lightweight, flexible battery technology to decrease cost and weight for future military and commercial space systems. PBEX was developed by Johns Hopkins University and is one of four On Orbit Mission Control (OOMC) packages on PicoSat 9:
