I am aware of all the factors you mention in your response and took what I thought
to be the best route to not be stranded at a destination airport. 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.

Okay, thanks. 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?
