what is VSR and DC DC and how do you determine which you have?
My needs are similar, although I seem to travel alone; here is my set up... bearing in mind it is for one personI am looking for some advice on a power setup for my travels / camping.
I am based in Brisbane and most of our camping involves driving 2-3 hours to our destination, camping for 2-3 days, then driving home.
My $9 VSR-isolator set up has not failed me in the past 25 years
Yeh, I'm not that uneducated I don't realise that it's just a switch. I was simply throwing in a cheap manual option for isolating the second battery into the mix. Before I progressed to a switch I used to just pull the inline fuse between the main and second battery in my old Landcruiser to ensure I didn't accidentally discharge the main/starter battery when camping (worked OK for 15 years ). My point restated, is that it works for me and I've not noted any harm to batteries from using a manual switch rather than a VSR.That's nota vsr champ. It's just a switch. A vsr is a voltage sensitive relay and it opens and closes dependant on the voltage from the feed side.
A set up with just a dumb switch is not going to be doing either of your batteries any favours.
That said if you're happy with it, all good.
