LITHIUM BATTERY (LI-ION/LIPO/LIFE) PROGRAM
Lithium battery (Li-Ion/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 a different charge technique 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 the charge process is also very important. It should be
precisely matched with the charged voltage of the battery: 4.2V for LiPo, 4.1V
for Li-lon, and 3.6V for LiFe. The charge current and nominal voltage cell count
must always be correct for the battery to be charged.

When you want to alter the parameter value in the program, press the start/enter
key to make it blink and then change the value with the Inc> or <Dec key. The
value will be stored by pressing the start/enter key once.
