Key highlights
The lithium-ion battery pack adopts industrial cylindrical single cells such as 18650, 21700, 46800, etc. The large capacity 55Ah and 110Ah square shape single cells are designed in series and parallel after strict capacity division. The industry-leading force, heat, and magnetic design schemes are adopted, making it equipped with advantages such as high specific capacity, stable structure, and precise temperature control. All types of battery packs have passed the verification of mechanical vibration, thermal vacuum, and mechanical impact space environment at the appraisal level. Modular batteries have the characteristics of flexible assembly and short supply cycle. They can be assembled into 23Ah/32Ah/55Ah/110Ah battery modules with 28V/42V bus voltage, and meet the task requirements of battery packs with different bus voltages and capacities through splicing and convergence. At the same time, customized products can also be provided according to user needs.
Applications
- Can be applied to Nanosat, Microsat and small satellites.
- Can be applied to LEO/SSO/space science missions.

Customization
All products are mainly based on standard specifications. For customized renovation needs based on standard products, we welcome communication and discussion.
Flight heritage
At present, our product has successfully tested in orbit on multiple satellites such as the Pr-1, pulsar experimental satellite, HY satellite, JS-1, and SD scientific experimental satellite. The longest in orbit flight has reached 7 years, and is still working smoothly.
Manufacturing
Pioneer Satellite has constructed China's first smart automated production line for satellite core components, with an annual output of 200 sets of satellite core components. The production line has successfully mass-produced solar arrays, elevating the product yield from 70% to over 98%. It also makes the production cycle 50% shorter, cuts the cost to 30% and enables a two-thirds reduction in lead time compared to traditional modes compared to traditional methods.
Export control
There are no restrictions toward battery products. It has been sold globally.
