Most members use just a separate mains charger, DC-DC charger and a solar controller. They don't seem to worry too much about a battery monitor, they just use a volt meter to monitor the batteries. Try pricing your own system with individual pieces of equipment.

Lefty I use a Votronic battery monitor, cost just on $200. They are a German made unit and come with a choice of amperages 100, 200 & 400 amp. Choose according to your needs. I use a 100 Amp unit as we only run a 360 Watt inverter and rarely draw more than 20 Amps from the batteries at any time. They monitor current in and out of battery system, battery voltage and keep track of battery charge condition either as Amp/Hrs remaining or % of full charge. I have found it to be a very useful piece of gear for monitoring my battery system and would not be without one. If you need further info please PM me for details.
Glen, I have a primary and 1 secondary battery under the bonnet and another one in the rear canopy on the HiLux. Thanks Alan i will have a look at that one
Sorry for delay as been offline for a while. I bought mine on Ebay from a NZ supplier some years ago as there was no Aust. seller. Now they can be obtained from Solar4RVs at similar prices. Yes Dorian that is what I use.
