    Dual battery rundown

    Hey guys,

    My recently acquired disco has a dual battery set up, which ive just noticed has a deep cycle battery included. I have absolutely no idea about the system, what to look out for, how to tell the way its set up.

    Can anyone give me a rundown on what i should be doing, swapping the batteries over periodically? or an incar read-out system that i can fit so i know whats goin on, on the go? I obviously have no idea, please go easy on me lol

    Got a brand name on the dual battery controller? Most systems are automatic, and connect the two batteries together when the main system is over a set voltage, say 13 volts, then both batteries are charged. Redarcs have a LED that lights up when the relay connects the two batteries together. When the main system voltage drops below that, the relay disconnects the auxiliary battery which keeps the main battery charged for starting. Camping loads (fridges etc) should be connected to the auxiliary battery.
