The replies are really helpful.. The last few posts refer to boats.. Did you guys use split charge relays or DC 2 DC chargers via alternator. To charge your leisure batteries.
Split charge relays on my boats. I had never even heard of DC 2 DC chargers back then and I'm still not sure what the point of them is unless it has more to do with modern "smart" alternators. I'm not sure how they work, and I'm always one for "keep it simple" as the simpler it is the less there is to go wrong. Very important on a boat. Surely connecting two batteries together via a set of relay contacts is as DC to DC as you can get? Why do you need any complex electronics to connect two batteries together when a piece of wire will do, perhaps someone can explain it to me, as at present they appear to be a solution to a problem that didn't exist.

Hi
If I had to choose one I would personally go for a B2B charger. Just because they are 100% guaranteed to charge you batteries. Even if you run out during the evening you have the option to let the car run idle for some time. Not the best option of course but better then having no power.
After having B2B I would add some solar also. They can most likely cover your daily usage so great for being off grid and stationary for a while.
Rain
Maybe, if the vehicle has a smart alternator, but a simple split-charge relay, which the O/Ps vehicle was already fitted with, will do the same job at no cost if the vehicle has an ordinary alternator. Agree about the solar though.
