The battery isolator, also known as a split charge relay, uses your vehicle's power to charge an auxiliary battery and blocks your starting battery from getting drained by your equipment when the engine is turned off. The auxiliary battery isolator will only allow the extra battery to charge at whatever rate the alternator can manage. Off-roader/caravan vehicles usually need to be equipped with a second battery to meet the demand for electrical appliances in the car. However, the second battery cannot be directly connected in parallel with the original car battery. The stalling use of electricity may cause the original car battery to lose power, and it is difficult to start the vehicle. On the other hand, the line load is too heavy when the two batteries are charging together. Therefore, a battery isolator is required.

The voltage reading below 16V is a 12V system, and the reading above 17V is a 24V system. When the voltage of the starting engine is higher than 13.5V (27V), the isolator is powered on after 5 seconds. It is normal for the voltmeters to have an error between 0.3V. When the main and auxiliary voltmeters show that the voltage is lower than 13V (26V) for 10 minutes, the isolator is disconnected immediately when it is lower than 12.5V (25V). The voltmeters will flash after disconnection.

The button indicator light flashes during the isolator is working, and the two voltmeters display normally. The Voltage of the system will automatically Detect after the isolator is energized. The Contact is made of High-Grade Copper to improve the electrical conductivity. The Aluminum Alloy Shell and Copper Contact provide low power consumption and power-saving LCD display voltage, as well as lengthen the life of the primary battery when your vehicle engine is off.
