Hyperion quality products!

The Super DUO3 is not to be confused with past models bearing the 0720 designation as they were all single-port chargers. This charger is sporting two identical output ports, each capable of providing 500W of raw charging power. "0720" is to be interpreted as 7 Cells - 20Amps max - per port, being a DUO charger. In order to provide all 500W per channel (1000W total), the Super DUO needs 24V-28V of input voltage but can naturally also be operated on lower input voltages (from 11V).

The EOS Duo3 features a robust metal body and a user freindly interface which operates both ports through a dual LCD display and also independently control each port. Charge any two packs with different voltage's/capacity's independently or two similar capacity packs in synchro mode as one pack. Intergrated cell balancer ensures that all cells balance evenly. Take advantage of the chargers extra functions from the PC with USB connection and control parameters like TCS, TVC etc. One Click charge, No need to play with the buttons every time, just load your regular batteries into the memory and set the charge parameters for once. Make your chargings easy. The EOS Software Suite gives you a realtime display of your batteries Charge/Discharge status alongwith graphical interface and indepth information like pack resistance, per cell voltage, output current/capacity and current operation mode. Now just relax and watch your batteries charge and let the Duo3 do the rest.
