    Blackcell Battery Charger

    $39.95
    Blackcell chargers are intelligent charger, which combines convenience and fast charging into a single unit. Charging times depend on each batteries current capacity, although the independent output (1A, 2A) and pulse charging circuit are compatible with any cylindrical Li-ion batteries (3.6/3.7v), Ni-MH and Ni-Cd batteries ranging in size between 10440 up to 21700. The BU4’s 3 LED display allows for clear viewing of the current charging status.

     

    Features

    • Four, independent micro-controlled charging slots allow for simultaneous charging at 5V DC USB input.
    • Automatically distributed charging current (500mA*4/1000mA*2/2000mA*1), 2000mA for slot 4 only. 500mA is the default setting for charging Ni-MH and Ni-Cd batteries.
    • LED display charging status 30%, 70%, 100%.
    • Li-ion and Ni-MH Ni-Cd batteries are automatically detected.
    • 0V voltage Activation capabilities. Trickle charge activated when the battery voltage is between 1.65-1.85V.
    • Faulty batteries and battery reverse connected batteries are automatically detected.
    • Charging mode: constant current and voltage.
    • DC input, the power supply is 5V 2A (Micro plug).
    • Automatically detected USB 5V/1000mA output function.
    • Certified by CE, ROHS, and FCC.
    • When no batteries are installed, the three LEDs will flash and then turn off one by one when the charger is connected to a power source.
    • When a bad battery is installed, the three LEDs will flash at the same time.
    • During the charging process, the three LEDs light up one by one, and will all stay lit until charging is completed.
