3. Operating Instructions
1. Connect the charger with a 12VDC outlet and connect the battery pack. The red 'power' LED should be lit.
2. First the charger will test the battery pack: the 'charge' LED is lit and the other 3 flash alternately.
3. To discharge: press the yellow charge/discharge button - the device is discharging if the LED above lights up.
4. After discharging, the VL7168 will automatically start charging. Select the appropriate charge current with the
rotary button. We recommended to select a charge current between 0.25C and 1C (C = the battery's capacity).
5. Remove the temperature sensor from its compartment at the right and put it around the battery pack. If the pack
should get too hot during charging, the charger will automatically reduce the charging current.
6. First, only the 'charge' LED will be lit. As the pack is charging, the '40%' and '80%' LEDS will be added. Then the
green 'ready' LED will be added and the 'charge' LED will go out. As the charging cycle is nearing completion, the
'40%' and '80%' LEDs will go out. When only the green 'ready' LED is on, the battery pack is fully charged.
7. Disconnect the battery pack from the charger and disconnect the charger from the DC source.
