Hi Alex;
I believe another feature of the EC2 is that it won't allow spark if the
RPM is less than ~300. While this unfortunately prevents hand propping, I
can't recall if this was added as a safety feature or if it is just a
consequence of EFI.
Voltage below 9 volts can't really spin it fast enough anyway.

cheers...
Todd

It seems to me a good solution to this would be to add a voltage regulator
that can run the ECU and EM2 at a lower voltage (say 6V). This would avoid
some frustration with low batteries on the ground and I think add safety
allowing longer flight times with a dead alternator.
