Victron Energy Argodiode Battery Isolator 80-2SC for Dual Battery Systems, 80A Capacity

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.

The Victron Energy Argodiode Battery Isolator 80-2SC is designed to enable the simultaneous charging of two batteries from a single alternator without direct electrical connection between the batteries. This feature helps prevent the discharge of the auxiliary battery from affecting the starter battery, ensuring reliable vehicle operation and extended battery life. Built with high-efficiency Schottky diodes, this isolator minimizes voltage drop, providing approximately 0.3 volts at low current and around 0.45 volts at rated output, which helps maintain optimal charging voltages. All models include a compensation diode that allows slight adjustment of the alternator's output voltage to counteract diode voltage drops, ensuring batteries are charged effectively and efficiently. Installing this isolator between the alternator and the batteries slightly reduces the charge voltage, which may result in less than full charge for each battery and potentially premature aging if not monitored. The device features a unique energize input designed for some alternators that require DC voltage on the B+ output to initiate charging. This input is current limited and ensures the alternator receives the necessary power when the engine run/stop switch is engaged, preventing reverse current flow and ensuring proper operation. The Victron Argodiode Battery Isolator is suitable for various applications requiring reliable dual battery management, such as RVs, boats, and commercial vehicles, helping maintain battery health and ensuring continuous power availability.
