I want to build a baffle around my auxillary battery to reduce the amount of heat from the extractors. What would be the best material to use as a heat sheild?

Nigel, for the baffle to be effective, there have to be two things happening. First, it needs to reflect heat back towards the extractors away from the battery, and second, there needs to be an airspace and preferrably a flow of cool air between it and the battery. For the first effect, steel is a decent material to make the shield from. If you can polish it on the side towards the extractors it will reflect the heat better. For the second effect, have an inch or two between the baffle and the battery for air to flow through, and have it open ended, maybe with an extension to the front of the engine bay to encourage airflow through it. CHeers, Alex.
