OPTIMUS batteries offer high capacity with low mass and volume. Our high quality lithium polymer batteries are optimized for Low Earth Orbit (LEO) missions with a maximum altitude of 850km. Utilized over a large number of missions; especially US CubeSat missions, these New Space solutions have an excellent track record spanning almost two decades as one of the most flown and reliable spacecraft batteries. In order to ensure consistent quality levels the batteries undergo rigorous testing, including tests performed by ESA and NASA.

The battery systems all have autonomous integrated heater systems to enhance operation at low temperatures. Each system has multiple protection systems in place at a cell, battery, and system-level which will automatically respond to external fault conditions in order to protect the battery and widersystem from irrecoverable damage. The OPTIMUS Battery range is compatible with International Space Station deployment safety requirements and can be compatible with a wide variety of launch platforms, including manned missions, when integrated into suitable platforms.


The highly scalable OPTIMUS battery range is available in 30Wh, 40Wh, and 80Wh capacity, with larger capacity available on request. Our inbuilt protections such as undervoltage protection, over-voltage protection and string over-current protection are based on over a decade of design heritage, guaranteeing power efficiency and consistency.


Battery selection is critical to the success of the mission. Having already demonstrated excellent performance on-obit on over 100 missions spanning almost two decades, our battery range ticks all the right boxes.


Qualified to NASA standards EP-Wi-032. Additional qualification and acceptance testing can be provided for manned flight in order to meet the necessary safety conditions.

The batteries are designed for integration with spacecraft that have an EPS compatible with lithium ion polymer technology and can easily be combined with the STARBUCK EPS range.
