Ramy,

Can you add a solar cell somewhere or replace lead/acid battery with
LiFePO4, if not already done?Â* Room for another battery?

While I don't wish to return to the sectional chart with concentric
circles and a "prayer wheel", it would be nice to have sufficient power
to drive all these new fangled contraptions.Â* Maybe I should remove the
espresso machine from my Stemme...Â* Naaah...Â* One needs one's luxuries. ;-)

Already have two lifePO4 + solar panel. With all the electronics I have, which includes LX9000, powerflarm, radio, transponder, Dell Streak, and the TN72 addition, my two batteries last around 10 hours which is plenty for most of my flights. If I am running low I can selectively turn off some of the instruments to extend the time. So bottom line, you should have sufficient power even after adding ADS-B.
