Spacecraft battery options are heavily influenced by advances in the terrestrial battery market, which is in turn driven mainly by the mobile electronics industry. Advances in battery technology can greatly benefit the performance of small satellites, but the suitability of these technologies for space is often an unknown.

Staff at Clyde Space have extensive experience in the use of commercial battery technologies in space. We can provide small satellite battery solutions using the following technologies:

  • Lithium Ion
  • Lithium Polymer
  • Nickel Cadmium

Our current space battery products include our CubeSat battery. The cells that we have selected for space use have undergone extensive evaluation, in collaboration with ESA, to assess their suitability for the space environment - including leak and bulge tests. They have also performed well under life tests.

Each batch of cells received at Clyde Space is subjected to Lot Acceptance Testing, and cells are matched by capacity before integration into a battery. Our battery systems have integrated balancing circuitry, over-voltage and under-voltage protection, plus over-current protection via a PTC which can be replaced easily in case of short circuit. Once assembled, our battery systems are fully tested to ensure all protection circuits are functioning, and the battery capacity is verified.

Other products and services from Clyde Space



This is due to the high quality systems and excellent customer service that we produce consistently for all of our customers. Over 40% of all CubeSat missions fly Clyde Space hardware, more than any other vendor. Clyde Space was the first space company to have an online CubeSat shop.

Electrical Power Systems

We also offer off-the-shelf power system products which have excellent performance specifications and extensive flight heritage. The designs are modular and have the flexibility to be easily configured to meet the requirements of bespoke projects. Clyde Space produce tailored Electrical Power Systems which are designed to your specifications.


DC-DC Converters

One is designed for Low Earth Orbiting small satellite applications, utilising COTS components and the other is for applications requiring very high reliability and radiation tolerances up to 100krads - note that this converter range can also be produced to 100krads ITAR free.


Solar Panels | Clyde Space | Glasgow

Clyde Space solar array design and manufacturing techniques have been developed based on traditional solar array assembly techniques, but adapted to reduce assembly costs in order to meet the tighter budget needs of the small satellite community.


CubeSat | EPS | Power Systems | ADCS | Structures | Solar Panels

Our solutions include complete or part Power Conditioning and Distribution Systems, Lithium Polymer Batteries, Solar Arrays and DC-DC Converters. In addition to our off-the-shelf products, Clyde Space has a wide selection of heritage systems for non-standard spacecraft. Our four main small satellite power system products are: SmallGEO Power; SmallSat Power; NanoSat Power; CubeSat Power.


SmallGEO Power | Clyde Space

The power system incorporates a number of main elements, including a 16 section Sequential Switching Shunt Regulator, hot redundant Battery Discharge Regulators, hot redundant Battery Charge Regulators and Power Distribution Module. For missions with power hungry payloads, in its unmodified form, our CommSat power system can manage over 40A at a regulated 50V.
