The Dual Voltage Jack allows easy two-step charging for batteries. By inserting the included Dual Voltage plug, the DLS will deliver an increased "quick-charge" for rapid charging of the battery. Quick-Charge voltages are relative to the voltage settings of the DLS (for instance, a nominal output voltage of 13.6vdc is increased to 14.2vdc).

Note: Location of the Dual Voltage Jack will vary depending on the DLS model.
The Dual Voltage Jack also provides simple installation of the IQ4 Smart Controller. By inserting an external IQ4 controller into the Dual Voltage Jack, the DLS automatically provides four-stage "smart charge" control.
