Battery distributor 2 80A diode argo 80-2SC - Victron Energy

Description

Diode splitters allow multiple batteries to be charged simultaneously from a single alternator, without connecting these batteries to each other. When discharging too, the batteries remain isolated, the use of the service battery, for example, will not discharge the starter battery.

ARGO splitters feature a reduced voltage drop thanks to the use of Schottky diodes: at low current the loss will be about 0.3 V, and at full power, the loss will be about 0.45 V. All models are equipped with a compensation diode that slightly raises the alternator's output voltage to compensate for the splitter's voltage loss.

Alternator power supply

Some alternators require a DC voltage on the B+ terminal output to start charging. Obviously, there will be DC when the alternator is connected directly to the battery. However, inserting a FET or Diode splitter will prevent any voltage/current feedback from the batteries to the B+ terminal, and the alternator will not be able to start.

The new "AC" diode isolators have a special current-limited power input that will supply the B+ terminal when the engine Start/Stop switch is off.
