Drain on my main boat motor battery

[Q_Ball]

Here is the switch. like Kentofnsl said, it's peace of mind. I went a little overboard according to some(my wife) but in my industry its all about redundancy and keeping things running if something fails. I have two switches, "house", "engine" VSR(voltage sensing relay) switches charging to house battery after engine battery is at 13.7V. Separate fuse blocks for each, two bilge pumps also separated. all LED lights, red and white interior, hatch lights in each hatch(no more flash light in my mouth).

If you want the switch but don't want to spend the money. I would be willing to trade the switch for some fishing knowledge. I've always been a trout/koke guy with limited time spent on other species.
