Smart Dual Battery Isolator 250A 12/24V Universal Charging Power Control Auto Connect

How Battery Isolator Works:

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. On the one hand, the stalling use of electricity is prone to 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 while 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.
