Frequently Asked Questions
What is the voltage drop on a Victron ArgoDiode battery isolator?
With Schottky diodes, the forward voltage drop is typically less than 0.3V at rated current—significantly lower than conventional diodes, reducing energy loss.
Does the Victron ArgoDiode charge lithium batteries?
Yes, but ensure the alternator voltage regulation and LiFePO4 BMS are compatible. The isolator itself does not affect voltage; it only isolates. For proper charging, consider a lithium-specific alternator regulator or an isolator with remote sense.
How does the ArgoDiode compensation diode work?
The compensation diode increases alternator voltage output slightly (around 0.6V) to offset the drop across the isolation diodes, so the battery receives the correct charging voltage.
Can I use this isolator with a high-output alternator?
It's rated for 80A continuous. For alternators above that, choose a higher amp model like the 160-2AC.

Decent product
Works well, but the terminals are a bit small for larger cables. You might need adapters. Otherwise, it's a good isolator.

It's okay. Does its job but nothing special. The build quality feels a bit cheap for the price, but it works.
