Integrated Back-up Battery System 

 

Model:  IBBS-12v-6ah-CRT 

  
 

 

 

 

 

 

 

  The 

Integrated Back-up Battery SystemIBBS,

 is an electronic system 

that combines a Lithium-Iron-Phosphate (Li-Fe-PO4) battery pack, a 
charger and switching logic in one convenient package.  The IBBS 
provides an engineered solution to enable an endurance bus for critical 
loads found in aircraft. It simplifies the wiring and installation of a source 
of back-up power by integrating all of the key elements in a single 
enclosure.  The 

IBBS

 system provides back-up power to critical 

electronic loads such as EFIS, GPS, Autopilots, Radios and engine 
monitor systems.    

 
  Integral to the IBBS is a lithium-iron-phosphate battery pack and a 

matched charging system to ensure the battery is properly charged and 
maintained.  The system also includes switching circuitry to provide a 
stable source of output power during normal and emergency operations.  
The IBBS system also provides signals to other equipment such as EFIS 
systems to communicate the operating state of the main aircraft bus as 
well as the state of the battery. 

 

  The IBBS system connects to the standard aircraft power bus and 

provides outputs to critical equipment that require back-up power.  
Additionally, the IBBS system provides surge and sag protection for
