BA08 High Energy Density Battery Array with On-Board Charging System
At a thickness of 23mm millimeters, the EXA BA08 High Energy Density Battery Array is a power store/delivery device designed to provide the highest energy capacity and redundancy at 88Whr per bank. All BA08 modules have integrated quad chargers at 2C or 4C and integrated Isolated Power Core for custom serialization or parallelization. The embedded PowerFlex technology enables the user to discharge the battery array with a much higher power capacity for longer times to accommodate power peaks in the payloads without having to invest more.
BA08 enables your system to perform longer and better and pack more power than a similar sized satellite, the double-sided arrays are user-configurable to output 3.7V or 7.4V and can be serialized for much higher voltages. BA08, as all the batteries in this family, has the unique capability to charge and discharge simultaneously, giving you a longer mission time and extending the life of the battery.
