Is one of your batteries actually going flat?

If so, it sounds like you have a problem that needs to be sorted out rather than a set up that needs changing.

Battery in poor condition?
Faulty equipment drawing large current?
Partial short circuit somewhere?

If your batteries aren't going flat then I wouldn't worry.

My current boat has two batteries - but only ever use one at a time for both starting and electronics. Always leave the plotter and sounder running if leaving the boat for a couple of hours and heve never had any problems.

Previous boat only had one battery and again no problems.

Thanks for that, i think i will adopt the 3rd way, so the electronics can be run from either battery and then i also have the option to have the batteries in parallel if one gets low.

my advise would be use the key type isolator but only keep 2 keys avalible, put one key away, this means you CANNOT accidently have both engines running charging the same battery
