Dual battery isolator 12 VDC,140A

Specifications:
When your engine is on and the start battery is sufficiently charged the isolator kit will begin charging the second (auxiliary) battery simultaneously.
When the voltage of the start battery drops beneath the cut off voltage (12.8v) for 5 seconds this isolator disconnects the starter battery from your auxiliary circuit.
This isolates the start battery and eliminates the possibility of draining it, ensuring that you always have enough charge to start your engine,
and also protects sensitive electronic equipment powered from the auxiliary battery from harmful engine start-up spikes.
Suitable for 12VDC Marine, 4WD, caravan and solar applications.
