There is a Warn battery isolator advertised on e-bay. Does anybody know if these have any advantage over conventional soliniods?

Looks like a diode isolator which will have the associated voltage drop which isn't good.

Dunno quite what it is but it looks like a flash version of a cole hersy switch. These things are the original duel battery setup and in my opinion still the best coz they allow you to test each battery on starting so you know if you have a sick one and can isolate it. With the newer systems the first you know you have a dead battery is when the other one dies as well and thats that. You also cant isolate a sick battery (easily) so it doesnt thieve charge from the good one

Some high-quality isolators have 'voltage display monitors' as part of the system or as an option, and yes, they cost more, but the point is they tell you the condition of each of your batteries individually, and continuously, well before the batteries are too far gone to be regained, unlike a manual switch when you have to take the time to actually test them yourself and find out only when they are already stuffed. The vehicle can also be ‘jump started’…
that said the cole hersy switch does have it’s place.

probably I am just a ludite. when working for the Geol survey and going some really remote places I found regular load testing of the batteries was effective - anything under 60% turf it
