Victron Energy Argofet 100-3 Three batteries 100A Retail

The Victron Energy Argofet 100-3 Three Batteries 100A is a FET battery isolator that lets one alternator or single-output charger charge up to three 12V or 24V batteries without connecting the batteries together. Rated for 100A maximum charge and alternator current, it helps prevent an accessory battery from discharging the starter battery.

Its FET design provides virtually no voltage loss, with less than 0.02V drop at low current and about 0.1V at higher current. An alternator energize input supports alternators that require B+ excitation, while M8 connections provide secure installation in marine, vehicle and auxiliary battery systems.
