Odyssey Batteries
I read with interest and enjoyed the article on aircraft batteries in the August, 2011 issue. There was brief mention of the Odyssey battery, as applied to homebuilders. I have Odyssey sealed batteries installed in two different aircraft, a Cessna 180 and a Cessna 185. These are both firewall-mounted, eliminating 10 feet of heavy-gauge wire. The balance impact is minimal, as this battery, in the box, weighs 14 pounds compared to the Gill that was removed, at 37 pounds.

These batteries are installed in accordance with a field approval, which is increasingly more difficult to obtain. This has been a win-win deal for me, however.
