Hello,
Just for information
I put a lipo battery in my Europa...for better results I change my regulator
by a Silent Hektik. Like this: https://www.silent-hektik.de/UL_R_912.htm

load i.e. Radio, GPS, Master Solenoid, Transponder. and then dynam
ic load i.e. Radio Transmitting, trimmer and flap operation
. With a static load of 8 amps I have 2 hours of battery capability
and can extend that if I close down transponder, put GPS on internal batter
y and other measures. In other words I can cross the channel and find an ai
rfield to divert into.

d working out the electrical load factors first and then considering how muc
h capacity your would need to divert should you loose an alternator. It's do
ne for IFR capable aircraft as part of the design.
