Victron Energy Argofet Battery Isolator Item # 969362
Description
Similarly to diode battery isolators, FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with diode battery isolators, FET isolators have virtually no voltage loss.
Features:
- Simultaneously charges two or more batteries from one alternator (or a single output battery charger)
- Voltage drop is less than 0.02V at low current and averages 0.1V at higher currents
