I also had a port to add battery power from an outside source. Previously if I went out 30 to 40 minutes and reduced power on a down wind leg and taxied a long way leaving the transponder, strobes, radio, and EFIS on the battery would not be up to par. I could watch the negative amp flow on the meter. The original Jabiru engine needed 300 rpm to generate enough spark to start. I also fixed that by adding an E-mag on the left side and an improved Honda coil on the right side. Now it's up and running before you can take your finger off the start button. This coupled with the 40 amp alternator that charges while taxiing makes the airplane much more reliable. Just my humble opinion. bobby ________________________________ Message 2 _____________________________________ Time: 04:13:08 PM PST US From: "Robert L.

I just downloaded the patent on the ibbs (8,189,305) along with 'related patents' citen on their website. I wonder if the circuitry in their patent truly represents the product . . . it's REALLY busy! The patent is pretty long in the tooth . . . and much simpler approaches to a similar product are on the market. Okay, installation instructions do include YEARLY checks for continued air worthiness. I presume one would check the chip's battery at the same time . . . which means the operator needs to develop his/her own airworthiness verification protocols. Igor, what size IBBS are you installing and have you established your projected loads and design goals for endurance?
