CubeSat and SmallSat Battery Packs

The minimum order quantity for SmallSat battery packs is 1 piece, CubeSat battery packs – 3 pieces.

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, while the EPS 1.0 battery pack features passive cell balancing along with integrated battery heaters and addressable temperature sensors over I2C.
The battery unit supports NanoAvionics’ EPS battery management functions, enabling controlled energy distribution, safe thermal operation, and autonomous or remote power switching.
