Ring brothers , Eddie Motorsports, feeler lots of companies make and sell nice charging ports . I'd agree with the trickle charger set up thou. My buddy has them on his cars and toys ....easy to tuck the lead out of the way.
I've not been a fan of any of the Optima products since they were sold.
I used a trickle / float chargers recently from Optima and was frustrated with it more than anything else. It would take 15 mins to "analyze" the battery.
