Heavy Duty Electronic 12V Dual Battery Isolator



Designed for use in dual battery systems e.g. a main battery and an auxiliary battery.
The auxiliary battery can be connected to a load, such as a camping fridge, while the main battery is isolated and not subject to any current draw. This allows you to start your vehicle using the main battery if the auxiliary battery is flattened by the load.
Automatically connects the auxiliary battery for charging once the main battery reaches the selected cut in voltage and disconnects it from charging when the main battery falls below the selected cut off voltage. May also be used with a single battery, operating as a low voltage cutout to prevent over discharge.
