One difference that I would try: Using a flat washer and short bolt to make the connection (for more clearance).

I was talking to a coworker about EV's, and threw out the term 'Optima Yellowtop' during the conversation. This coworker remarked "Oh, you don't want to use those. They use to be a good battery, but their quality has gone way down and guys have been having a lot of trouble with them in the last couple years."
Has anyone else heard of similar reports?

I have heard that exact line quite a few times. I think it may almost be to the point where they have just gotten a bad rap.

A couple guys get bad batteries, then that gets announced to the internet, and passed on to perpetuity.

I have had NO problems at all with mine! (Other than shorting the one out, but I can't blame that on the manufacturer....)
