Victron Energy Argofet battery isolators 200-3AC, allow simultaneous charging of three batteries from one alternator, without connecting the batteries together
12/24 Volt auto ranging: Victron Energy Argofet battery isolator will automatically adjust to a 12-Volt or 24-Volt system
In contrast with diode battery isolators, FET isolators have virtually no voltage loss. Voltage drop is less than 0.02-Volt at low current and averages 0.1-Volt at higher currents
Discharging the accessory battery for example will not result in also discharging the starter battery
When using Victron Energy ARGO FET Battery Isolators, there is no need to also increase the output voltage of the alternator. However, care should be taken to keep cable lengths short and of sufficient cross section
