this is the BEP vsr and selector switch, as you can see the lower red cable goes to the starting 1 battery and the top red cable goes to stereo 2 battery. Each are connected to the VSR. The right red cable goes to the engine. There is a small sensing wire that goes to a negative pole for dual sensing of the voltage sensitive relay . All house stereo connections are made directly to the 2 battery.
This is very similar to the blue sea. With this BEP set up you can if you want to adjust which battery starts your engine 1,2, or both, which battery you want to have the priority charge 1,2, or both.
But as with the blue sea I just set it to 1 motor battery and let it do all the work
