Argo FET Battery Isolators

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. Discharging the accessory battery for example will not result in also discharging the starter battery.

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. Discharging the accessory battery for example will not result in also discharging the starter battery.
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. 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.

Example:
When a current of 100 A flows through a cable of 50 mm2 cross section (AWG 0) and 10 m length (30 ft), the voltage drop over the cable will be 0,26 Volt. Similarly a current of 50 A through a cable of 10 mm2 cross section (AWG 7) and 5 m length (15 ft) will result in a voltage drop of 0,35 Volt!

Alternator energize input
Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new Argofet isolators have a special current limited energize input that will power the B+ when the engine run/stop switch is closed.

Recharge Batteries with battery isolator by Victron

The battery isolator is an electrical device for solar power systems that are designed to divide Direct Current electricity supply into a number of branches, while it permits current one direction in each of the branches. In simple words, the battery isolator Victron increase efficiency by charging more than one battery at the same time. For example, an alternator without connecting the battery terminals together in parallel. This really is helpful because a week or dead battery will drain the charging from a strong or charged battery when the two batteries are connected directly.

Precaution

For a person with no technical knowledge, the downside could be complexity, the mingling of two and more batteries and its associated cost; however, the outcomes are more fruitful and cost savings.

In case a diode type isolator is used, which is very common for many people, there is an additional voltage drop in the circuit between the charging source and the batteries.

Use of Battery Isolator

Battery isolators are common on RVs, adventure and recreational vehicles, utility vehicles, marine boats, yachts, aerospace applications, and large haul trucks where the battery is dedicated to starting the engine. The second battery run the accessories and connected loads. For example, winches, radar, instruments etc.

The battery isolator keeps an eye on the starter battery that it has an ample amount of energy to kick start the vehicles’ engine. It will start feeding current into the starter battery when it senses the battery charge status is low, i.e. loads on the auxiliary battery, including refrigerator and navigational lights, can quickly drain the battery fully or during the event of auxiliary battery failure.

The battery isolator Victron is also used in vehicles with large high powered car sound systems and off-road vehicles to accommodate current loads in bulk. Several technologies have been used to achieve control the DC supply in this manner.
