Lixx Charge Program - GRAUPNER SJ ULTRA DUO PLUS 80 Instructions D'utilisation

The following screen displays appear if you select the battery type LiXX.
The screen shows a maximum of four lines; pages 2 and 3 appear when
you move the Select arrow further down.
STORE MODE START storage mode
LiXX batteries should never be left fully charged or discharged when they
are to be stored for a protracted period, as either extreme can damage
them. Ideally they should be charged to about 60% capacity prior to sto-
rage - and that is exactly what Store mode achieves automatically by
charging or discharging the battery connected to the charger.
With the Select arrow in the store mode line (STORE MODE START), start the process by holding the ENTER button pressed in for two seconds.
Charge CHG
The Charge line (CHG) displays the charge current and the final charge voltage per cell. These parameters can be selected with the ENTER button, and
altered using INC or DEC. The charge current is limited to 2C by default, i.e. if you enter 2200 mAh under battery capacity in the charge memory, the
charge current is automatically set to 4.4 A; you can reduce this value, but not increase it. If you wish to charge at a higher current, you must first increase
the C-rate in the Maximum charge rate (CHARGE RATE) line, where the maximum setting is 5C.
The charge current can be set to any value in the range 0.1 to 20 A, taking the maximum charge power into account. Depending on the power supply
and the battery connected to the charger, the unit may be unable to charge at the selected current, i.e. the maximum possible current may not be used
for charging. If this should occur, the screen displays the charge current actually in use.
WARNING: it is essential to observe the maximum charge current for your battery! This is generally printed on the pack itself. If you are
unsure, charge the battery at 1C (e.g. 2.2 A for a 2200 mAh battery). If the battery is charged using incorrect settings, the result could be
serious damage to the battery, or even a fire!
Press the ENTER button again to highlight the final charge voltage: the value matching the battery type is now displayed (see table in Chapter 12). You
can reduce this value if you wish, but you cannot increase it. For example, reducing the value makes sense in very low temperatures, since a cold LiPo
battery can be overcharged at the normal final charge voltage of 4.2 V / cell. Reducing the value by 0.1 V to 4.1 V will increase the effective life of the
battery.
With the Select arrow in the Charge (CHG) line, start the charge process by holding the ENTER button pressed in for two seconds.
Discharge DCHG
IThe Discharge (DCHG) line displays the discharge current and the final discharge voltage per cell. These parameters can be selected with the ENTER
button, and altered using INC or DEC. The discharge current is limited to 2C by default, i.e. if you enter 2200 mAh under battery capacity in the charge
