BA0x High Energy Density Battery Array

Flight Heritage since 2013

3,000.006,300.00

As thin as 7 millimeters thick, the EXA BA0x High Energy Density Battery Array is a family of power store/delivery devices designed to provide the highest energy capacity and redundancy: From a minimum of 19.9Whr to a maximum of 53.2Whr per bank. For missions like 1U Cubesats, the BA0x enables your system to perform longer and better and pack even more power than a 3U configuration, the double sided arrays are user configurable to output 3.7V or 7.4V. All our batteries are fully customizable to your mission’s need in terms of output, cable, connectors or interfaces and options are available as integrated Carbon Nanotubes Thermal Transfer Bus (CN/TTB) shield which allows missions to reuse the spacecraft self-generated heat, integrated MT01 Magnetorquer and integrated thermal sensor.

The BA0x battery family is a cells-only array battery, no electronics on board, 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 BA0x 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 BA0x 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.
