Just an FYI, if you have your rigs sitting somewhere you can't get a charge to the batteries, I've gone to a solar panel to remedy that problem, got a 35 watt panel, monitor, fused to 2 batteries, it will charge 1st battery to 90 percent, then move to the second battery, I was away for 2 weeks, checked them yesterday, good charge on both. Since a lot of boats are still on trailers waiting for the water to drop as I am, it's a nice alternative to pulling them out. I set the panel laying across a back seat.
