Multi-function charger “V-charge 50”

14. Saving/loading rechargeable battery data

The charger has a total of 10 memories in which you can save rechargeable battery data/settings. They can be loaded again on demand.

a) Selecting/setting rechargeable battery data

• Select the function „BATT MEMORY“ in the main menu of the charger with the button „INC“ or „DEC“.

• Confirm the selection by pressing the „START/ENTER“ button. The memory number flashes.

• Select one of the 10 memories with the buttons „INC“ or „DEC“.

PROGRAM SELECT

BATT MEMORY

[ BATT MEMORY 1]

ENTER SET->

If there already are data in the memory, the display will alternate, e.g., between the rechargeable battery type and the cell number, as well as the charging and discharging current.

When the memory is empty, only „ENTER SET ->“ is displayed.

• Confirm the selection of the memory number by pressing the „START/

ENTER“ button.

The rechargeable battery type is displayed first; see figure on the right.

BATT TYPE

LiPo

The buttons „INC“ and „DEC“ select the desired setting function (e.g. battery type, cell number, charge current, etc.). A description of the respective setting functions shown is included on the following pages.

If a setting is to be changed, briefly push the button „START/ENTER“. The respectively adjustable value flashes.

Change the flashing value with the buttons „INC“ and „DEC“. Keep the respective button pressed for quick adjustment.

Complete the setting by briefly pushing the „START/ENTER“ button. The respective adjustable value stops flashing. Then you can select another setting function, see above.

If you want to save all previous settings in the memory selected at first, call the setting function „SAVE PROGRAM“ at the end with the buttons „INC“ and „DEC“ and briefly push the button „START/

ENTER“.

SAVE PROGRAM

ENTER

Otherwise, all settings are lost! Then the display shows the indication with the flashing memory number again.

To discard previous settings and cancel setting mode, push the button „BATT. TYPE/STOP“ repeatedly until you are back in the main menu.

The following functions are available:

Depending on the set battery type (LiPo, LiIo, LiFe, NiMH, NiCd, Pb), different setting functions are available. For example, the setting function for the charge end voltage per cell is only available for lithium rechargeable batteries.

Therefore, always set the rechargeable battery type first and only then the other data, so that the charger can offer the setting functions matching the rechargeable battery type.

Rechargeable battery type

BATT TYPE

LiPo

For this, select the rechargeable battery type „LiPo“, „LiIo“, „LiFe“, „NiMH“, „NiCd“ or „Pb“.

As described above, this selection must be made first, since the right setting functions matching the rechargeable battery type are only displayed then.

Battery voltage

BATT VOLTS

7.4V(2S)

Depending on the set rechargeable battery type, the rechargeable battery voltage can be set here.

However, it is not possible to set any voltage, but the steps depend on the rated voltage of an individual cell of the respective rechargeable battery type; see chapter 7.

For example, the rated voltage of a cell in LiPo rechargeable batteries is 3.7 V; the rechargeable battery voltage can thus only be set in steps of 3.7 V (3.7 V, 7.4 V, 11.1 V, etc.).

Charging current

CHARGE CURRENT

2.2A

Set the desired charging current here (0.1 - 7.0 A). It must be selected according to the rechargeable battery used.

Observe that the charging output of the charger is up to 50 W. Depending on the cell number, the maximum charging current may therefore not be available.

Discharging current

DSCH CURRENT

2.0A

Set the desired discharging current here (0.1 - 2.0 A). It must be selected according to the rechargeable battery used.

Observe that the discharging output of the charger is max. 5 W. Depending on the cell number, the maximum discharging current will therefore not be available.

33

Discharging end voltage per cell

DSCH VOLTAGE

3.0V/CELL

Here, the voltage per cell at which discharging ends can be set.

Attention! Never set the voltage too low. For lithium rechargeable batteries, this may cause deep discharge and permanent damage to the rechargeable battery!

Observe the table in chapter 7 and any special information of the rechargeable battery manufacturer.

Charging end voltage per cell

TVC=YOUR RISK!

4.20V

Here, the voltage per cell at which discharging ends in lithium rechargeable batteries can be set.

Attention! Never set the voltage too high. This can result in a fire or explosion with lithium rechargeable batteries!

Observe the table in chapter 7 and any special information of the rechargeable battery manufacturer.

Deactivation at overtemperature

TEMPERATURE

CUT-OFF 50C

The charger can automatically cancel charging/discharging if the rechargeable battery exceeds the temperature set here.

To use this function, an external temperature sensor is required (not enclosed). It must be connected to the respective socket of the charger.

Maintenance charging current (for NiMH and NiCd only)

TRICKLE

100mA

Set the maintenance charging current here. When a NiMH or NiCd rechargeable battery is fully charged, it will lose part of its capacity again by self-discharge. The maintenance charging current (short charging impulses, no continuous charging current!) ensures that the rechargeable battery remains fully charged. Thus also prevents crystal formation in the rechargeable battery.
