Argo 1403AC 3 batteries 120A

With a load current distributor, multiple batteries can be charged simultaneously with a single alternator. During discharge, the batteries are separated by the diodes. For example, when the service battery is discharged, the starter battery will remain fully charged. Thanks to the use of Schottky diodes, the voltage drop of the Argo load current distributors is very low: only 0.3 V at low current and 0.45 V at maximum current. This is no less than 50% better than traditional diodes!!

Alternator compensation connection
All ARGO AC models are equipped with a compensation diode output that can be connected to the alternator to slightly increase the alternator voltage. This compensates for the voltage drop across the load current distribution diodes. This is a different connection for each alternator regulator.

Alternator ‘energize’ connection Some alternators only start charging if there is voltage present on the B+ connection. When the alternator is connected directly to a battery, there will be voltage on the B+ connection. However, a diode or FET load current distributor isolates the batteries from the alternator so that it will not start. The new ARGO diode load current distributors have a separate current-limited ‘Energize’ connection with which voltage can be applied to the B+ connection when the motor's ignition switch is turned to the ignition position. You connect the energize connection to the switched contact of your ignition switch.

FET load current distributors
A better but more expensive solution is the FET load current distributor, which has a maximum loss of 0.1V!

Intelligent isolation relays
Especially for vehicles, we recommend intelligent isolation relays to charge a second battery. A major advantage compared to a diode or FET load current distributor is that the car installation does not need to be modified.
