Battery Memory (Data Store/Load)
The charger can store up to 10 different charge/discharge profiles for each channel. You can
keep the data pertaining to program setting of the battery of continuous charging or discharg-
ing. Users can call out these data at any time without any special program setting.
Terminal Voltage Control(TVC)
The charger allows user to change the end voltage. (for expert user only)
Internal Independent Lithium Battery Balancer
ULTIMA 250 DUO uses an individual-cell-voltage balancer. It isn’t necessary to connect an
external balancer for balance charging.
Balancing Individual Cells Battery Discharging
During the process of discharging, ULTIMA 250 DUO can monitor and balance each cell of
the battery individually. Error message will be indicated and the process will be ended auto-
matically if the voltage of any single one cell is abnormal.
Adaptable to Various Type of Lithium Battery
ULTIMA 250 DUO is adaptable to various types of lithium batteries, such as LiPo, LiIon and
the new LiFe series of batteries.
LiHV Mode Available
The additional LiHV mode is able to charge the new generation of LiPo and LiIon batteries
with a higher end of charge voltage (4.35V).
Fast Charge Mode and Storage Mode of Lithium Battery
Special modes for specific needs. Fast Charge reduces the duration of charging. Storage
Mode lets you control the final voltage of your battery as preparation for long time storage in
order to prolong the usable lifetime of the battery.
Re-Peak Mode of NiMH/NiCd Battery
In re-peak charge mode, the charger can peak-charge the battery once, twice or thrice in a
row automatically. This is good for making certain the battery stays fully charged.
Delta-peak Sensitivity for NiMH/NiCd
Delta-peak sensitivity for NiMH/NiCd battery: The automatic charge termination program
based on the principle of the Delta-peak voltage detection. When the battery’s voltage ex-
