SKYRC Ultimate Duo 1400W/30A Balance Charger/Discharger


SKYRC Ultimate 1400W is a dual output DC charger which is capable of charging/discharging all kinds of batteries. In synchronous mode, when charging two same batteries, both channels can set by operating one channel.
SKYRC Ultimate 1400W charger has lithium battery meter and lithium battery internal resistance meter. It has automatic charging current limit, capacity limit, temperature threshold and processing time limit.


Synchronous Mode
In Synchronous mode, when charging two same batteries, both charging channels can be set by channel one.

Balance Port for Charging/Discharging
For some small batteries without main connector, you could use the balance socket to charge and discharge the battery to storage status.

LiHV Mode Available
The additional LiHV mode is able to charge the new generation of LiPo batteries with an end of charge voltage of 4.35V.

Special Features:

Mega Power 1400W/30A:
SKYRC Ultimate 1400W employs the circuit that features an output power of 700W x2. It can charge/discharge up to 20S NiCd/MiMH or 8S Lithium batteries with maximum current of 30A.

Lithium Battery Balancer:
SKYRC 1400W employs an individual-cell-voltage balancer. It isn’t necessary to connect an external balancer for balance charging.

Program Data Store/Load:
The charger can store up to 10 different charge/discharge profiles for your convenience. Users can call out these data at any time without any special program setting.

Battery Meter:
The user can check battery’s total voltage, the highest voltage, the lowest voltage and each cell’s voltage by this charger.

Battery Resistance Meter:
The user can check battery’s total internal resistance and each cell’s internal resistance.

Maximum Safety:
  • • Automatic Charging Current Limit
  • • Capacity Limit
  • • Temperature Threshold
  • • Processing Time Limit
Terminal Voltage Control (TVC):
The charger allows user to set the charge/discharge end voltage.
