The Integrated Back-up Battery System, IBBS, is an electronic system that combines a rechargeable 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 into a single enclosure. The IBBS system provides back-up power to critical electronic loads such as EFIS, GPS, Autopilots engine monitor systems and electronic ignition modules.

Integral to the IBBS is rechargeable 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 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 to critical equipment that requires back-up power. Additionally, the IBBS system provides surge and sag protection for connected equipment, allowing operation of critical equipment during engine starting. Additionally, the IBBS system is approved for use as a back-up source of power for the Light-speed electronic ignition system.

The IBBS system is suitable for use with equipment such as Garmin GNS and GTN series navigators, G3X series of avionics, Grand Rapids Technologies EFIS systems, Advanced Flight Systems EFIS, Dynon EFIS, and MGL EFIS, TruTrak Autopilots and EFIS, and Trio Autopilots.

Q: I have the Integrated Back-Up Battery system Model IBBS-12V-6AH part # 11-12653 it has the 15 pin connector for wiring. How do I get the 15 pin plug and wiring harness ? I bought the unit from Aircraft Spruce but can not find the connector.

Two Options: 1. Part number IBBS-DSUB, this is just the raw connector and you would need to make your own harness. the price on that is $15.50. 2. IBBS-HARN-LIFE IS PRICED AT $75.75 and includes the connector and harness.

Q: Good day Sir Please advise if MODEL IBBS-12V-4AH, Battery Pack is still available to purchase as it does not appear on the Website.

Unfortunately the IBBS-12V-4AH is no longer available. The notes in our system say, "Item no longer produced, refer to IBBA-12V-6AH, part # 11-12653."
