Oh and regarding manual switches that join the batteries, I would never have them on my boat. The number of time I have helped people who have flattened their batteries because they forgot the switch was on both. I have used the Cyrixs for many years and recommended them and have yet to know of a failure. They will do the job safely and properly. I want control. In the winter the starter battery needs some extra charge and the odd burst for the LB, in the summer it's the opposite. I have deliberately kept the systems apart and I want to keep it that way. Much as I dislike manual switching, there is no other way, unless your suggested gizmo never joins the batteries.

What is somewhat alarming is that I find myself in agreement with Graham on all points!

I just hope that I am not the one driving past when you have flat batteries. In the years of boating it has always amazed me how often I have had to go along side another boat pass my extra long jump leads across and get them started. In about 80% of cases it was a 1,2, both switch that had been left on or even switched on when the domestics went flat during the evening. A week ago I got waved down out in the country here, a couple with a mobile home could not start it. I carry jump lead started them and the cause that drat switch. Maybe it is time I stopped carrying jump leads and just smiled sweetly Oh BTW the gizmo never joins the batteries unless they are being charged and need charged.

Two options I would consider are a lithium jump start pack and a second solar panel.
I bought a cheap Suaoki jump start pack 18000mah(that's a bit cheeky as its not measured at 12v) anyway I managed to get a blokes boat engine to start (BMC 1.8) when he had got the battery to the point where it would not turn the motor over.
I was impressed by that.

That is rather condescending and comes across as implying everybody else is an idiot I have used battery 1/2/1+2 switches for more years than I care to remember and like Gazza I have never had a problem.

What amazes me Graham is that in all those years you've never thought to explain how to properly use a battery selector switch.
It doesn't take long, costs nothing and is quicker than procuring and fitting a voltage sensing relay.

Condescending - possibly but it’s just his style! But implying everybody else is an idiot, no you are quite wrong. In fact the opposite - only an idiot would think they could never make a mistake. It’s just like most (Male) drivers think they are great and could never crash, and yet inexplicably there is much crashery every day! A non-idiot is a person who, wherever possible, designs out the possibility of making inevitable human mistakes.

John I think no one is an idiot, yet to meet a boater who is. The point I was trying to make possibly badly is I give advice and as always it is advice and it is up to the person whether they take it or not and it has no effect on how I feel about them. You and Gazza have not had a problem probably many others have not. But it amazes me how many of the times I have had to help people over the years the 1, 2, both switch has been a cause of the problem, of course that is not true, the cause has been wrong use by the owners, but they never seem to learn as has demonstrated by knocks on the cabin a couple of days later by people who have been helped having done it again. I suppose it is those who do not really understand batteries & electrics on boats who have problems.
