Victron Argodiode 80-2AC for 2 Batteries 80A Battery Isolator

Victron Argo Diode 80A Battery Isolator for 2 Batteries (ARG080201000R)

The Victron Argo Diode 80A is a diode-based battery isolator designed to allow simultaneous charging of two separate battery banks from a single charging source, such as an alternator or battery charger, while preventing batteries from discharging into each other.

This isolation solution is especially suitable for marine installations, recreational vehicles and professional mobile systems where separate starter and service batteries are required, ensuring safe and reliable energy management.

Frequently Asked Questions (FAQ)

Can it charge two batteries at the same time?
Yes, it allows two battery banks to be charged simultaneously from a single charging source.

Can batteries discharge into each other?
No, the internal diodes prevent any discharge between connected battery banks.

Does it cause voltage drop?
As with all diode-based isolators, there is a small voltage drop, which is reduced by the use of Schottky diodes.
