I believe the terminals of the BlueSea ANL holders are stainless. I applied some terminal conductive paste for corrosion control on the aluminum ring terminals. The Stainless strip connects the two ANL holders. We'll see how this combo holds up. All parts are easily accessible and replaceable if necessary after flying. Thanks for the responses.

It would be a short piece, about 3 inches long if that makes a difference? It will carry a LOT of current but it does have a significant temperature rise if subjected to starter currents. .025 is a bit skinny. I think all the brass (and copper) straps I've seen on airplanes is at least .050 if not thicker. See: http://aeroelectric.com/Pictures/Wiring_Technique/Contactor_Interconnect/ Brass has a small fraction the electrical conductivity of copper. Look for a display like this: Emacs! In your hardware store or hobby shop. I think it includes copper sheets in .025 which would be much better and probably adequate. Also consider soldering up a short piece of welding cable with terminals of appropriate spacing. http://www.aeroelectric.com/articles/big_term.pdf Brass isn't out of the question . . . but it's not the best choice.
