Specifications Operating voltage range: DC 11.0-18.0 Volt Four Outputs Max. Charge Power: 320Watts (4 x 80Watts) Four Outputs Max. Discharge Power: 40Watts (4 x 10Watts) Charge Current Range: 0.1-6.0A Discharge Current Range: 0.1-2.0A Current Drain for Balancing Li-Po/Ion/Fe: 300mA/cell Li-ion/Fe/Polymer Cell Count: 1-6cells NiCd/NiMH battery Cell Count: 1-15cells Pb Battery Voltage: 2-20V Net Weight: 1130g Dimension: 225.4 x 158.6 x 62.4mm Introductions SKYRC Quattro B6 employs the circuit that features four totally independent but identical power outputs which are powered 80 watts each. Total powers are 320 watts. As a result , it can charge or discharge up to 4 packs of 15 cells of NiCd/NiMH or 4 packs of 6 series of lithium batteries simultaneously. Quattro B6 has four individual cell voltage balancer at each outputs, so it does not required any balancer separately when charging lithium batteries (LiPo/LiIon/LiFe) for voltage balancing. The twin-fan cooling system is so smart and efficiently. The fan speed is controlled by internal temperature sensor. SKYRC Quattro B6 allows you to plug 4 batteries into one charger simultaneously, and it will intelligently and automatically charge all 4 of them at once to their maximum capacity. To top of it, the batteries being charged do not even need to have the same configuration. You can connect different chemistry?Ni-MH/Ni-CD/LiPo/LiFe?batteries into any of the charging ports. No more staying up late for charging batteries. This is special edition bundle with RCECHO Apps license key included for more fun!. RCECHO is a registered trademarks.
