So I will be rewiring my Fin & Feather soon, and this will also mean new batteries. I'm looking for a reliable lightweight setup. From what I understand the Odyssey PC680 should have no problem being used for (Johnson 25) electric start, 500 gph bilge, GPS (nav lights and livewell will be used on a minimal basis). Now my question is, would it be wise to use another PC680 connected in series with the first one to power a 12v, 50lb Thrust, Motorguide on occasion? One member over on the Custom Gheenoe forums claimed that "A ODYSSEY PC680 will run a 40# trolling motor for 1 hr on hi." Any truth to this? Trying to avoid the large trolling motor batteries.
