Integrated Back-up Battery System 

 

Model: IBBS-12v-2ah      

  

 

 

 

 

 The 

Integrated Back-up Battery System

is an electronic system that combines a 

Ni-mh battery pack, a charger and switching logic in one convenient package.  The 
back-up battery system has been engineered for use as a source of back-up power 
for single instrument applications.   This unit may also be used to provide back-up 
power for electronic ignition systems utilized on 4 cylinder and smaller applications. 
 
 Integral to the IBBS is a nickel metal-hydride 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 an output signal to 
communicate the operating state of the back-up bus as well as the state of the 
battery. 
 
 The IBBS system connects to the standard aircraft power bus and provides an 
output directly to the avionics requiring back-up power.  The IBBS has a pass through 
power feature allowing it to provide normal as well as back-up power to connected 
equipment.  Additionally, the IBBS system provides surge and sag protection for 
connected equipment, allowing operation of critical equipment during engine starting. 
 
  
 No other uses of the IBBS system are permitted except for those identified in this 
installation manual. 
 
 IBBS must be installed using the current aircraft standards and practices as shown 
in AC 43.13-2A/1B.   The installer/builder is solely responsible for determining the 
suitability of the installation and use of this product.
