That kit will keep them completely separate when turned to on (Deep Cycle turns on for electronics, Starting for Engine), combine runs them in parallel (Deep cycle paralleled with starting and powering everything, just like "both" on yours). The black box that comes in the kit is the charging relay. The relay parallels the batteries when it senses a charge. So once the motor is running it parallels the two batteries to charge them both, as soon as the engine turns of the circuit is broken, separating the two batts. This allows them to charge together but then discharge individually.

I love it as when I am at the sandbar all day with the stereo going, gps going, lights, etc I can really kill a battery but it will have no effect on my starting battery. Then once I am back up and running home the relay kicks on and charges up the electronics battery. Also, just an FYI I installed mine when I had two starting batteries, and then once they wore out of old age I went with a Deep Cycle and a Starting.

Lastly, if your not a sandbar rat like I am you can still have a use for the kit. If you have two starting batteries, just wire up the second battery anyway to the switch and this kit will always keep it charged up. If for some reason your main batt dies, you click over to combine and it taps into that other fresh battery.

Sorry this is long winded, hope it was at least clear. If you have any other questions fire away.
