Design a 12v car battery management system for use in a camping environment. It should basically combine the functions of four different devices - a 40 amp battery charger; a dual battery isolator; a solar charger and a dc-dc converter.

It should have the following features:

- Be able to monitor the state of charge of at least two batteries

- Be able to isolate either battery when battery voltage drops too low

- Be able to charge either battery from multiple sources including 240v (40A), solar power (MPPT), and alternator.

- Be a smart charger - varying the charge voltage to charge as quickly as possible, while keeping the voltage at safe levels for each battery type (Gel, AGM, flooded cell, etc.)

- Be able to be used for 6v, 12v & 24v systems.

I don't know what an appropriate budget is. Obviously cheaper is better, but I'm after a good design.
