Special Features
Optimized operating software: The charger features an automatic function that sets the feeding current during charging and discharging. Especially for lithium batteries, it can prevent overcharging, which may lead to an exploding battery. The function automatically disconnects the circuit and buzzes if the malfunction is detected. All the settings are configurable by the user.

Internal, independent lithium battery balancer: The charger features an individual cell-voltage balancer, which makes it unnecessary to use an external balancer for balance charging.
Individual cell balancing during discharging: During discharging, the charger will individually monitor and balance each cell in the battery. When the voltage of any cell is deemed abnormal, an error message will be displayed and the discharging process will end automatically.
Adaptable to various types of lithium batteries: The charger is suitable for various types of lithium batteries, such as Li-ion, Li-poly, and Li-Fe.
Fast and storage modes for lithium batteries: The charger features special functions to suit various purposes: the fast charge mode considerably reduces the charge duration whereas the storage mode keeps the battery at an ideal storage voltage.
PC-based analysis via USB: The charger offers a PC-based function in order to analyze the battery’s characteristics. The function features a voltage, current, and capacity graph, and also shows each cell’s voltage for lithium batteries. The USB adapter is available separately.
Maximum safety: The automatic charge termination program is based on the principle of delta-peak voltage detection: when the battery’s voltage exceeds the threshold, the process ends automatically.
Automatic charging current limit: Charging NiCd and NiMH batteries can be set with the charging current upper limit. It is a useful battery with low impedance and capacity when charging in auto mode.
Capacity limit: The charging capacity is always calculated as the charging current multiplied by the time. If the charging capacity exceeds the limit, the process will be terminated automatically when setting the maximum value.
Temperature threshold : The battery’s internal chemical reaction will cause the battery’s temperature to rise. If the temperature limit is reached, the process will be terminated. Only available with an optional temperature probe.
Processing time limit: The charger can be set with a maximum process time to avoid any possible effect. Data storage and loading: The charger has a data memory bank for a maximum of five batteries. Different programmes can be stored and loaded for your convenience.
Cyclic charging and discharging: To stimulate the battery’s activity, one to five cyclic and continuous charge-to-discharge or discharge-to-charge programs are available for battery refreshing and balancing.

Connection Diagram

Please connect your battery and charger as follows when using the balance charge mode. The main battery must be connected with the balance lead connector before charging.
Failure to do so will damage the charger!

Operation

9.1 Initial Setup
By default, this charger will be set to the user settings when first connecting an 11-18 V load. To alter the
parameters, press START/ENTER and change the value with INC/DEC. Store the value by pressing START/ENTER once.

Starting screen
This screen displays the nominal voltage of the lithium battery. There are three kinds of lithium batteries: Li-Fe (3.3 V), Li-Io (3.6 V) and Li-poly (3.7 V). This is very important for the correct setup as a wrong value may damage the battery during the charging process.
This charger automatically recognizes the battery type. However, a deeply discharged battery can be perceived incorrectly. To prevent errors and damage, please set the term time – at about 10 minutes or even more for larger batteries – so the charger will recognize the battery correctly. If in doubt, leave the term time to the default setting.

Display of the trigger voltage for automatic charge termination of NiMH and NiCd batteries. The effective value ranges from 5 to 20 mV per cell. If the trigger voltage is set higher, there is a danger of overcharging the battery; if it set lower, there is a possibility of premature termination. Please refer to the battery’s specifications (NiCd default: 12 mV, NiMH default: 7 mV).
An optional feature is the temperature cut-off option using a temperature probe contacting the surface of the battery. If this option is on, set the maximum temperature at which the charger should allow the battery to reach during charging. Once a battery reaches this temperature during charging, the process will stop to protect the battery.

The battery warms after each charging/discharging cycle. The program will insert a time delay after each charging/discharging cycle to allow the battery to cool down before beginning the next cycle. The valid value ranges from 0 to 60 minutes.
When the charging process starts, the integrated safety timer starts running simultaneously. If an error is detected or the termination circuit cannot detect whether the battery is fully charged or not, the charger is programmed to prevent overcharging.

Safety Timer Settings

capacity in mAh	current	safety timer
2000	2.0 A	(2000/2.0 = 1000)/11.9 = 84 min.
3300	3.0 A	(3300/3.0 = 1100)/11.9 = 92 min.
1000	1.2 A	(1000/1.2 = 833)/11.9 = 70 min.

The program provides maximum protection. If the delta-peak voltage cannot be detected or the safety timer times out, the charging process will stop automatically when the battery reaches the user-set maximum charging capacity.
A beep sounds every time a button is pressed or a different mode is selected. The beep function 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 user-set value, the program will end forcibly to protect the input battery.

9.2 The Lithium Programme (Li-ion, Li-poly, Li-Fe)
This charger is only suitable for charging lithium batteries with a nominal voltage of 3.3, 3.6 or 3.7 V. Different batteries have different charging techniques. There are two charging methods: the constant voltage and the constant current method. The charge current varies according to the battery capacity and specification. The final voltage is very important and should precisely match the voltage of the battery: Li-poly is 4.2 V, Li-ion is 4.1 V and Li-Fe is 3.6 V.
When you want to change the parameters, press START/ENTER to select and change the value with INC/DEC.
Store the value by pressing START/ENTER once.
