 So today, we're on the Open 262, which is the smallest boat in the sport fish lineup. Take a look down at the battery select switch. This boat has twin 200 Yamaha's on it. So on your engine bank, that's going to control those two batteries. Your house switch is going to control its own two batteries designated for all your electronics for the house. The unique thing is, this system has a voltage sensitive relay in it. What that is, is it's taking power from the motor and sending it directly to the battery bank for whichever battery needs it most. So let's say for instance, you're out at the sandbar, you run your electronics all day, your house batteries are now depleted. Whenever you fire the boat up to leave the sandbar, this system is going to realize that and send that power directly to those house batteries, charging them back up. Once they get to the charge level, it will then alternate and start sending current back to the engine batteries or whichever battery needs it the most. This will be the system that will never let your batteries get below 12.5 volts, which is a really unique system while you're running the engine.
