English
This screen sets the termination voltage of battery types (LiPo 4.1-4.3V/S, LiIo 4.0-4.2V/S, LiFe
3.5-3.7V/S, LiHv 4.25-4.45V/S, Pb 2.3-2.45V/P). Use the default in the middle of each range
but the ability is there for experienced modellers to vary if needed.
Program select Lithium battery
The program is only suitable for charging Lithium batteries with a nominal voltage of 3.3/ 3.6/3.7V / 3.85V/cells.
Different batteries have different charging techniques. There are two linked processes termed as constant voltage
and constant current. The charge current varies according to battery capacity and specification.
The final voltage individual cell is very important. It should precisely match the voltage of the battery type: LiPo is
4.2V, LiIo is 4.1V, LiFe is 3.6V, LiHV is 4.35V. The charge current and total voltage of the battery should be correctly
set. The final voltage is not adjustable and is set at safe value already.
When you want to change the values of parameters, please press the button to make it flash and then use the
or button to change the value. Then press the button again to store the value.
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1000)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
Safe timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by the current,then divide the result by 11.9. Set this
number of minutes as the value for the safety timer setting . If the charger stopped at this time limit, about 140% of
the capacity will have been fed into the battery. For example:
This program, provides you with two languages (English and German). Press the button
again, and a beep will be sound, you can see the “English” is flashing, at this moment, press
the button, or press the button, to select the language.
