Victron Argodiode Battery Isolator 80-2SC - 2 Batteries - 80A

Victron Argodiode Battery Isolator 80-2SC by Victron Energy offers efficient battery management tailored for marine, automotive, and RV applications. This isolator allows simultaneous charging of two batteries from one alternator without risking cross-discharge between starter and accessory batteries.

Key Features:

• High-Efficiency Schottky Diodes: Minimizes voltage drop to approximately 0.3V at low current, ensuring optimal battery performance.
• Compensation Diode: Increases alternator output voltage slightly to counteract the voltage drop, maximizing battery charge.
• Current Limited Energize Input: Ensures that your alternator functions effectively, even with specific models that require DC voltage to start charging.

Ideal for boaters, RV enthusiasts, and automotive users, this product is supported by Victron's reputation for quality and reliability, ensuring that your battery systems are well-managed and efficient. Don't compromise on your power needs—invest in the Victron Argodiode Battery Isolator today!

Argodiode Battery Isolator 80-2SC - 2 Batteries - 80A

Argodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high-efficiency Schottky diodes.

The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current, the voltage drop is approximately 0,3 V, and at the rated output of approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator. 

Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely. 

Alternator energize input

Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.
