SKYRC Ultimate 20A 400W Balance Charger

Special features

Optimized operating software

Ultimate 400W features the AUTO function that set the feeding current during the process of
charging or discharging. Especially for Lithium batteries, it can prevent overcharging which may lead to an explosion due to the user's fault. It can disconnect the circuit automatically and alert 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 terminated 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 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 users convenience, it can store maximum 10 data of different batteries. You can establish
the data 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.
