Hi Brad, Re: Engine Bay Side Panels (or in your case, "Battery Bay")

Here's what I did:

Using masking tape I made a parallelagram and cut it out with a sabersaw. Then after trimming the edge I glassed the panel back in with an inch opening at the back.
I considered putting in a second one but this venting was enough to get rid of surplus engine heat and keep it from entering the footwell.

You mentioned heat dissipation from the batteries, so some form of venting will be nice to have.

Best wishes,
Tom
