Key highlights
The EPS Battery Packs are designed to operate as part of NanoAvionics’ integrated Electrical Power System (EPS) or as plug-and-play power storage for your spacecraft's proprietary electrical power system, providing reliable onboard energy storage using several Li-ion cells.
The EPS 2.0 battery pack includes overvoltage protection, active cell balancing, integrated battery heaters, and addressable temperature sensors over I2C lines.
The battery unit supports NanoAvionics' EPS battery management functions, enabling controlled energy distribution, safe thermal operation, and autonomous or remote power switching.
