Battery isolators may not be the best way to go if you are designing a new system, but if you want to upgrade an existing system and don't wish to do a total rewiring job then using this Argofet low loss isolator is a practical and economical way to go. run the other wires from isolator to batteries as previously stated. Isolate each battery circuit and allows each battery to discharge and charge according to its own needs. Overview Specifications Eliminate multi-battery drain when the charging system includes two or more battery banks. run new wire from alternator to battery isolator. Diode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Diode Battery Isolators Eliminate multi-battery drain when the charging system includes two or more battery banks. this wire splits and also goes to the starter. When using ARGO FET Battery Isolators, there is no need to also increase the output voltage of the alternator.Some alternators require a B+ voltage at a terminal in order to start charging and this isolator has a special dedicated connection for that purpose. came up with a simple solution: remove +wire from alternator and cap it off. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents. In contrast with diode battery isolators, FET isolators have virtually no voltage loss.

This isolator allows simultaneous charging of three battery banks.

DIODE BATTERY ISOLATOR GENERATOR
So discharging the accessory battery will not result in also discharging the starter battery. The Diode Battery Isolator The diode type battery isolator uses semiconductor diodes to split the current from the alternator or generator and charge 2 or more batteries at the same time. Like diode battery isolators, FET isolators allow simultaneous charging of two or more batteries from one alternator without connecting the batteries together.
