BA07 High Energy Density Battery Array with On-Board Charging System
The EXA BA07 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 52 Whr to a maximum of 66 Whr per bank. All BA07 modules have integrated dual 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.
BA07 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. With three variant base battery cells and single- or double-sided options, all our batteries are fully customizable to your mission’s needs in terms of output, cable, connectors or interfaces.
FEATURES
