Victron Argodiode Battery Isolator for 2 Batteries - 12V/24V - 80 Amp

Retail: $46.00
Our Price: $39.10
In Stock
When your trailer or house battery pulls down the start battery, this isolator charges two batteries from one alternator without connecting them. Its Schottky diode design reduces voltage drop, so both batteries charge while staying separated.This isolator keeps both batteries electrically separate while still charging them from a single alternator, so accessory loads can't pull from your starting battery.
