LITHIUM (LIPO/LILON/LIFE) PROGRAM
Lithium battery (LiIon/LiPo/LiFe) program
These programs are only suitable for charging and discharging Lithium batteries with a
nominal voltage of 3.3V, 3.6V and 3.7V per cell. These batteries need to adopt different
charge technique that is termed constant current (CC) and a constant voltage (CV)
method. The charge current varies according to the battery capacity and performance.
The Lithium battery is charged at a
constant current until it reaches the
final charge voltage of 4.2 V per cell
(B). After this point the voltage is
kept at a constant level, and the
residual charge takes the form of a
declining current curve (C) until the
cut-off point (D) is reached. Charge
current = C/10. At this point the
battery can be disconnected from
the charger, and is ready for use.
The final voltage of charge process is also very important; it should be precisely matched
with the charged voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and 3.6V for
LiFe. The charge current and nominal voltage as for cell count set on the charge program
must always be correct for the battery to be charged. When you are willing to alter the
parameter value in the program, press start/enter key to make it blink then change the
value with Inc> or <Dec key. The value will be stored by pressing start/enter key once.
CHARGING LITHIUM BATTERY IN THE CHARGE MODE
The program provides maximum capacity protection function. If the
delta-peak voltage cannot be detected or the safe timer times out,
the charge process will stop automatically when the battery reaches
the maximum charge capacity set by the user.
A beep to confirm users' operation sounds every time a button is
pressed. A beep or melody sounds at various times during operation
to confirm different mode changes.
These functions can be switched on or off. This function monitors the
voltage of the input battery used to power this charger. If the voltage
is lower than the value set by the user, the program will end to
protect the input battery.
