Abstract
Generally, a system includes a control circuitry configured to detect a current wherein the detected current is one of a battery discharge current or a battery charging current; a first transistor configured to disconnect a load from at least one of a battery and a DC/DC converter if the battery discharge current exceeds a maximum battery discharge current setting; and a second transistor configured to adjust the charging current to maintain the charging current at or near a charge current setting.
