A system is provided for preventing battery drain of a motorized vehicle and methods for using the same. The system may include a voltage sense module, a current sense module, a relay module and an optional overcurrent indicator module. The battery voltage sense module may sense a battery voltage and send an under-voltage signal to the relay module when the battery voltage goes below a predefined voltage threshold. The current sense module may sense a current of the load and send an overcurrent signal to the relay and the overcurrent signal to the overcurrent indicator module when a current of the load is higher than a predefined current threshold. The relay module may be configured to disconnect the power from the load upon receiving at least one of the signals. The system may advantageously be encapsulated in a smart fuse that has a standard fuse form factor.
