Victron Energy ArgoDiode 160-2AC Battery Isolator 2 Batteries 160 AmpThis battery isolator allows simultaneous charging of two batteries from a single alternator without directly connecting them. Using Schottky diodes, it minimizes voltage drop during charging. The special current-limited energize input powers the positive terminal when the engine run/stop switch is closed. A compensation diode can adjust output voltage to offset the drop over the diodes. Rated at 160 amps for two poundsProductdimensions5.9 x 4.7 x 2.4 inchesMaterialPlastic
