Special features

Optimized operating software

Ultimate 400W×2 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×2 employs 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, Ultimate 400W×2 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×2 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 batteries 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 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 batteries activity.
