In the illustrated embodiment shown in FIG. 9, the logic flow 900 may measure a current from a battery with a Hall Effect sensor, the current powering a primary load and a secondary load at 902. At 902, a status of the battery may be calculated based on the measured current. The status of the battery may be compared to a predetermined value at 906. At 908, a relay may be activated when the status of the battery is below the predetermined value, activation of the relay may prevent the current from powering the secondary load.

As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present invention are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.
