$250-750 AUD

Paid on delivery
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.
