DA1174 - Dual Battery Management System
It manages a starter battery and a separate auxiliary battery: while the engine runs the two are linked through a heavy-duty power relay so both charge from the alternator, and when the engine stops they are automatically separated so auxiliary loads cannot drain the starter battery. A manual override links the batteries on demand - for load sharing when jump starting or running high-current equipment such as a winch, inverter or compressor - before reverting to automatic operation.
The system supports auxiliary equipment such as fridge-freezers, inverters and lighting. It is supplied with a wiring loom (with sealed connector and battery/crimp terminals) and a dash-mounted battery monitor that displays the charge level of both batteries and the alternator charging voltage.
