Fully Automatic: Automatically combines two batteries when and isolates the two batteries when not .

Unique Characteristic: There is no voltage drop compared to the battery isolation diode (0.6V).

Universal Size: Fits heavy duty modular fuse box series (BF43x) and battery switch, matching mainstream products in market.

LED Light: Built-in LED indication light (ON when VSR starts). It also has a remote LED port that indicates the status of the VSR.
