Special features

Optimized operating software

Ultimate 400W features the so-called AUTO function that set the feeding current during the process of
charging or discharging. Especially for Lithium batteries, it can prevent the overcharging which may lead to
an explosion due to the user's fault. It can disconnect the circuit automatically and alarm once detecting any
malfunction. All the programs of this product were controlled through two way linkage and communication,
to achieve the maximum safety and minimize the trouble. All the settings can be configured by users!

Internal independent lithium battery balancer
Ultimate 400W employs an individual-cell-voltage balancer. It is not necessary to connect an external
balancer for balance charging.

Balancing individual cells battery discharging
During the process of discharging, Ultimate 400W can monitor and balance each cell of the battery
individually. Error message will be indicated and the process will be ended automatically if the voltage of any
single one cell is abnormal.

Adaptable to various type of lithium battery
Ultimate 400W is adaptable to various types of lithium batteries, such as Li-ion, LiPo and the new LiFe series
of batteries.

Fast and storage mode of lithium battery
Purposes to charge Lithium battery varies, fast charge reduce the duration of charging, whereas store state
can control the final voltage of your battery, so as to store for a long time and protect useful time of the battery.

Maximum safety
Delta-peak sensitivity: The automatic charge termination program based on the principle of the Delta-peak
voltage detection. When the battery's voltage exceeds the threshold, the process will be terminated
automatically.

Automatic charging current limit
You can set up the upper limit of the charging current when charging your NiCd or NiMH battery; it is useful for
the NiMH battery of low impedance and capacity in the 'AUTO' charging mode.

Capacity limit
The charging capacity is always calculated as the charging current multiplied by time. If the charging
capacity exceeds the limit, the process will be terminated automatically when you set the maximum value.

Temperature threshold
The battery internal chemical reaction will cause the temperature of the battery to rise. If the temperature
limit is reached, the process will be terminated.
This function is available by connecting temperature probe, which is not included in the package.

Processing time limit
You can also limit the maximum process time to avoid any possible defect.

Data store/load
For user’s convenience, it can store maximum 10 data of different batteries. You can establish
the data contains program setting of the battery to charge or discharge. These data can be called
back at any time you need and the process can be executed without program setting.

Cyclic charging/discharging
1 to 5 cyclic and continuous process of charge>discharge or discharge>charge is operable for battery
refreshing and balancing to stimulate the batterys activity.
