If you have any idea for locating the battery ahead of the firewall, I'd like
to hear them.
I mounted two batteries on the firewall in my 320. They are both 12ah
B&C recombinant gas batteries. One is mounted on the engine side and its
partner is mounted exactly opposite on the cockpit side (no right rudder
pedals). Through bolts hold aluminum angle for support and threaded rod
passing through the firewall holds both against the firewall. Together,
they are 24 ah and weigh about the same as a standard G-25. A contactor connects them electrically for engine start. Afterword they
are separated and one is connected to the main electrical system and the
60 amp alternator. The other is connected to the essential system and
the 8 amp B&C alternator running off a govenor pad. Two completely
separate and independant yet connectable electrical systems for a very
small weight penalty. The same switch that turns the 8 amp alternator on
disconnects the two systems so that you can't have any conflict between
the two alternators.
