I'm more of a boat person than a car person, and am wondering if anyone has a set-up two batteries (like on boats) - house and start?
I've been reading so much about grounds and battery voltage to ECUs during start, I'm wondering if anyone has added a relay to the ignition and a charge controller or auto-charging relay, with a second battery?
Sounds kind of crazy, but I'm not wild about this >10.5 V while cranking business. Anyone?
