Victron Energy ArgoDiode battery isolators 160-2AC allow simultaneous charging of two batteries from one alternator. Alternator energize input Victron Energy new AC diode isolators feature a special current limited energize input that will power the B when the engine runstop switch is closed. Diode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery, for example, will not result in also discharging the starter battery. Victron Energy Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator, this compensates for the voltage drop over the diodes in the isolator.

Victron Energy Argofet battery isolators 200-3AC, allow simultaneous charging of three batteries from one alternator, without connecting the batteries together. 1224 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.

Purpose this voltage sensitive relay is design for two battery systems SUITABLE for Acid-Lead batteries, NOT SUITABLE for Lithium batteries, allow to having two separate power sources while charging by one alternator, it's all need to charge and isolate two battery systems.. Primary Battery Protected cuts in at 13.3 volts and cuts out at 12.8 volts. Ensure your primary battery is always charged and ready to start your engine, the secondary will be charged after the primary battery's volts exceed 13.3 volts.. Heavy Duty this voltage sensitive relay is heavy built to suitable for almost anywhere even off-road, which is water resistant, shock resistant, dust proof and withstand unexpected extreme weather environments.. Compatible used for DC 12 V two battery systems isolate and charge, universal used for car, vehicle, RV, ATV, UTV and boat, also two battery electrical equipment.. Easy to use this VSR comes with mounting plate and 4 bolts for install. 100 SATISFACTION no reason for return or change..

BRL500 handles 500 Amps continuous and 700 Amps Surge. Eliminates multiple battery drain as it stops battery bank from getting power from each one. Prevents the equipment from discharging the main battery when it is operated while the engine is off. Does not create a voltage drop to the second battery like conventional isolator. Extends battery life.Excellent waterproof performance, high quality in any weather conditions.
