Ed Anderson had originally told me about these batteries, and I went with 2 of them for some redundancy, and to eliminate running a large set of cables from the rear to the front to power the avionics, landing lights, etc. Steve -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]On Behalf Of Paul Sent: Tuesday, January 18, 2005 5:43 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: New discovery... Hi, Steve....I am also using the Odyssey PC680. Only have one of them, and when I am cranking the starter, my voltage still shows 11.5 to 12 volts. Great battery, lightweight, and does not require a vent tube.
