For those large capacity lipo packs, the SkyRC Ultimate Duo 2 x 400W Charger packs the punch.

The Ultimate 800 is the ideal field charger for pilots flying large electric models, with each of its 400W outputs being able to charge a 6S 5000mAh LiPo at over 3C (check LiPo manufacturers recommended charge rate).

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.
