Have 60 amp and 20amp B&C alternators.Want to mount dual batteries. Considering two Odyssey PC680 batteries. Thinking about mounting mounting both on engine compartment firewall. Would appreciate advice in this regard as well as alternate location of 2nd battery.

Depending on which powerplant and which fuel systems you go with, your T/M/P cables will penetrate the firewall on the left, right above where a "symmetrically mounted" 2nd Odyssey battery would go. You'll also need to watch out for the fuel pressure hose running up to the transducer manifold. You would probably want to relocate the transducer manifold to a more centered position on the firewall. That might force you to go with custom hoses (no big deal, just more money). Other than that, I believe my left firewall is relatively free of crap. You can purchase Van's FWF drawing(s) of the firewall individually to get a better sense of what you're up against. But...I would think that building a battery box in the cockpit, centerline, just aft of the firewall would be a good location. Take a peek at any RV-6 out there with a PC680 and you'll probably get some good ideas.

Better to put the second Batt on cockpit side of FW due to limited space of everything on the engine side. But I am sure it is possible but it will be harder to work with and maintain for the rest of your life.
