Default 12V 24V separation?


I am new to this whole scene so please bear with me:

On my small stick steer jetdrive boat I have a 12V cranking battery for starting and two 12s (24V) for the trolling motor. All the electronics on my boat, i.e., lights, nav lights, fishfinder/GPS, bilge pump are currently powered by the cranking battery. Because I do not use the the electronics very much due to my primary/only body of water being a shallow rocky river for the most part, my current thinking is I should keep everything OFF my cranking battery except the engine which is a jet drive. If I cannot use my trolling motor or fishfinder/GPS I am not overly concerned. If I cannot start my engine I am way concerned.

Have the best of both worlds. A Combiner100 and the Trollbridge24 will leave your starting battery isolated from loads but will automatically charge all 3 batteries whenever the engine is running, often leaving you independent of shore power charging.
