5.2. Lithium-ion (LiFePO₄) batteries
When charging a lithium-ion battery, the charger uses a specific charging
algorithm for lithium-ion batteries to maximise their performance. Select LI-ION
using the MODE button.
5.3. Fully user-programmable charging algorithm
If the three pre-programmed charging algorithms are not suitable for your
purposes, you can also program your own charging algorithm using Bluetooth or
the VE.Direct interface.
If a self-programmed charging algorithm is selected, the NORMAL, HIGH and LI-
ION LEDs will not be lit. The status LEDs indicate the location of the charging
program in the charger.
If the MODE button is pressed during a self-programmed charging algorithm, the
charger will return to the pre-programmed NORMAL charging algorithm.
5.4. If a load is connected to the battery
A load can be applied to the battery during charging. Note: The battery will not
be charged if the load current exceeds the output current of the battery charger.
Reconditioning will not be possible if a load is connected to the battery.
5.5. Starting a new charging cycle
A new charging cycle starts if:
A. The charger is in the float or storage phase and the current rises to its
maximum value for more than 4 seconds due to a load.
B. The MODE button is pressed while charging.
C. The mains power is disconnected and reconnected.
