We’ve also been installing a backup battery for the EFIS to keep it up and running while the starting is drawing the primary battery down. This would also supply the EFIS for some time should the dual alternators and primary battery fail. The battery had to have a tray fitted to restrain it, and then an diode was installed so that only the EFIS can be fed from this battery.
