200 Amp 3 Bank Argo FET Battery Isolator | Victron ARG200301020R

FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. Unlike diode battery isolators, FET isolators have virtually no voltage loss.  When using ARGO FET Battery Isolators, there is no need to also increase the output voltage of the alternator. Care should taken however to keep cable lengths short and of sufficient cross section.
