BA06 High Energy Density Battery Array

The BA06 battery family is a semi-independent battery module with integrated chargers, this liberates you to select whatever EPS system you like or already have and supercharge it in order to obtain the best from any product you may have selected without compromising your system standards, the BA06 family can integrate with almost any EPS system actually in the market. When coupled with our DSA family of deployable solar arrays based on artificial muscles, the BA06 batteries are capable to provide even longer mission lifetimes, as our own satellites can attest: Almost 4 years in orbit and still working.

Every array is tested and qualified in our own facilities and shipped with full reports and packed with additional match connectors interfaces. Check the paper in the documents section of the product to know more about in-orbit test results and the engineering of the batteries, the BA0X family has flight heritage since 2013 in 4 missions.
