Image of Space Inventor - Battery // BAT-14-P4 on the satsearch marketplace

Key highlights

The BAT module is available in two variants: A 4 cell 14.4 nominal voltage version and a 8 cell 28.8 nominal voltage version. The modules are built on 18650 Lithium-Ion technology and designed for extended battery lifetime, easy integration, and operational safety. The design comes with a daisy changing feature for connecting multiple modules in parallel. Depending on the configuration, 50Wh and 100Wh capacity is available for single modules, providing flexible and powerful solutions for most nano and small -satellite missions.
