250 AMP Dual Battery Smart Isolator Universal 12V/24V Voltage Sensitive Relay Intelligent Dual Battery Isolator for Car, Truck, ATV, Battery Starter Controller Heavy Duty Power Switch Charge Relay

About this item

  • Voltage: High current 250 Amp/ Continue Current: 250A normally open/ Universal application 12V/24V, LCD display voltage of two batteries
  • Automatically Connection Voltage (Delay 5 seconds) : 13.5V-16V(12V working voltage);27V-32V(24V working voltage)/ Automatically Disconnect Voltage (Delay 5 seconds) : 12.5V,disconnect immediately if it is below 12.5 V
  • Function: 250Amp battery isolator is a primary battery saver, which used to combine two batteries when an alternator is charging (engine running) and isolate them when not charging (engine off) so you can still start your vehicle.
  • Designed with Small Size, Can Fit Anywhere!/ Wide Use on a variety of vehicles--12V/24V Trucks, ATVs, UTVs, Boats, RVs, Vans, Off-road Vehicle, Caravan & Camping Applications.
  • Easy to install, Just power wire in, power wire out. No Need to discharge your vehicle's original battery by trying your new equipment off-road

Main Functions:

Detect the main battery firstly, read the voltage and identify the two system. The voltage reading below 16V is a 12V system, and the reading above 17V is a 24V systems.

  • When the Voltage of the starting engine is higher than 13.5V(27V), powered on the isolator 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, disconnect the isolator immediately while it is lower than 12.5V(25V). The voltmeters is flashing after disconnection.

The button indicator light flashes during the isolator is working, and the two voltmeters display normally.

Why need the isolator

Off-roader/caravan vehicle 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 charging together. Therefore, a battery isolator is required.

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.
