5. Button functions

BATTERY TYPE button

When you press this button, the currently set battery type - NiCd, NiMH, Li-Po / Li-Io or Pb (lead-acid) - starts to flash.

While the battery type is flashing, further pressing of the BATTERY TYPE button will switch to the next battery type in the following
sequence (NiCD è NiMH è Li-Io / Li-Po è Pb è NiCd è ...).

If you press another button (or no button), the battery type ceases to flash after about five seconds.

Holding this button pressed in, the current charge settings are displayed for about three seconds.

ENTER / START button

If you press this button briefly, the variable value in the current menu starts flashing.

Press the ENTER button again, the next variable value starts to flash.

If you press no button for about three seconds, the value ceases flashing.

Holding this button pressed in starts the charge process or if charging is occurring, stops the charge process.

INC/DEC buttons

With these buttons the flashing values can be increased or decreased, or charging/discharging modes are selected as per the flow
charts.

Refer to the flow chart diagrams for step by step directions

on what button to press for each function.

For discharging or cycling batteries, please note the Discharge Current capabilities chart in this manual. This
function is only practical for lower voltage and lower capacity packs such as used for Tx and Rx power.

6. Programming for NiCd mode or NIMH mode

Select Battery type

Select the type of battery, NiCD or NiMH with the battery type button.

Charge current

In this menu the charge current can be set within the range 0.1 A to 5 A in increments of 50mA using the INC and DEC buttons.

Discharge current (Note Discharge Current capabilities chart in this manual)

In this menu the discharge current can be set within the range 0.1A to 1A using the INC and DEC buttons.

Final discharge voltage

In this menu the termination voltage for the discharge process can be set within the range 0.1 V to 16.8 V.

Charge / Discharge cycles (Cycle)

In this menu you can set the values and method of the charging / discharging cycles.
C->D charge to discharge = ending with discharged battery
D->C discharge to charge = ending with fully charged battery
Number of cycles: 1 to 5

Press and hold down the ENTER button to start the charging/discharging or cycling process.

7. Programming for LiPo and LiIo mode

You can use the unit to charge a maximum of five Lithium cells. The combined charge method of constant current and constant
voltage ensures that your Lithium-Ion and Lithium-Polymer batteries are fully charged every time. The unit starts by charging at a
constant current. As soon as the pack reaches a cell voltage of about 4 V the charger switches over to constant voltage. The constant
voltage charge process is terminated when the charge current falls below 100 mA. This ensures that the battery is fully charged at the
end of the charge process.

Battery type

In this menu the battery type Li-Po or Li-Io can be selected using the INC and DEC buttons.

NOTE: take care to select the correct battery type!

The maximum voltage for Lithium batteries is as follows: 4.1 V per cell for Lithium-Ion (Li-Io) batteries, 4.2 V per cell for Lithium­Polymer (Li-Po) batteries. The difference in voltage makes it extremely important to select the correct battery type (Li-Po or Li-Ion)
with great care, and to check the setup before starting the charge process. If you select the wrong battery type, the pack may be
damaged or ruined, and could even explode.

Battery capacity

In this menu the capacity of the battery to be charged can be set within the range 100 mAh to 5000 mAh in increments of 50 mAh
using the INC and DEC buttons.

Voltage for Lithium Ion batteries (Li-Io)

In this menu the nominal voltage of the battery to be connected for charging and discharging can be set using the INC and DEC
buttons. Possible values are 3.6 V, 7.2 V, 10.8 V, 14.4 V and 18.0 V.

Voltage for Lithium-Polymer batteries (Li-Io)

In this menu the nominal voltage of the battery to be connected for charging and discharging can be set using the INC and DEC
buttons. Possible values are 3.7 V, 7.4 V, 11.1 V, 14.8 V and 18.5 V.

Discharge current (Note Discharge Current capabilities chart in this manual)

In this menu the desired discharge current can be set within the range 0.1 A to 1 A using the INC and DEC buttons.

Charge current

For safety reasons the charger always uses the 1 C value as the charge current for Lithium cells (Li-Po or Li-Io). The current is
calculated from the battery capacity you have entered.
Example for a Li-Po cell of 1500 mAh capacity: 1 C = 1500 mAh, charge current = 1.5 A

Press and hold down the ENTER button to start the charging/discharging or cycling process

8. Programming for Lead-Acid battery mode

Charge current

In this menu the charge current can be set within the range 0.1A to 5A in increments of 100mA using the INC and DEC buttons.

Battery Voltage

In this menu the voltage of the battery to be charged can be set within the range of 2V through 12V in increments of 2V using the INC
and DEC buttons.

Discharge current (Note Discharge Current capabilities chart in this manual)

In this menu the discharge current can be set within the range of 0.01A to 1A using the INC and DEC buttons.

Press and hold down the ENTER button to start the charging or discharging process.
