No, I'm not moving to CA (I couldn't afford to live there). From what I have seen, most O-320 conversions use the G-25 battery, even when it is moved behind the baggage area. I will work fine and the G-35 is just excess weight in my opinion. Apparently the person doing the conversion was worried about not having enough cranking capacity with the G-25 and long cables. If you want a firewall battery use the stock G-25 and battery box/mounting configuration.

Odyssey battery? Odyssey is a good battery, albeit a bit expensive. It would require a field approval, whereas the O-320 engine conversions that I am aware of allow the battery to be mounted either fwd. in the stock location or aft to compensate for a fwd. CG. There is no field approval required if the STC allows this and the battery could be relocated fwd. even if it was originally located aft.
