Kino Flo SYS-BK22 overview

  • 1Description

The Block/KF21 Double Battery System from Kino Flo 28.8V (20-34 VDC) system with two 140 Wh NiMH, a dual charger, universal power supply, both U.S. and Euro power cords, and a Mafer Mount with a 3' long, 3-pin XLR. The system is compatible with the lights indicated below.

  • KF21 Nickel Metal-Hydride Battery

    Partnering with BlockBattery, Kino Flo has created the KF21 Nickel Metal-Hydride Battery to power their LED fixtures. The 140Wh, 28.8V battery provides 1 hour 10 minutes run time for compatible light fixtures and recharges in 1.5 hours in the charger that's made for it. Battery adapters may be used to access 14.4V for products that have 14.4V inputs. The KF21 is compatible with Celeb 250 LED DMX, Diva-Lite 20/30 LED DMX, FreeStyle 31/21 LED DMX, and Select 20/30 LED DMX light fixtures.

  • Dual Block Battery Fast Charger System with Universal Power Supply

    The Kino Flo Dual Block Battery Fast Charger System with Universal Power Supply includes the charger and a 100 to 240 VAC power supply. The system will charge two KF21 block batteries in 1.5 hours.

  • Mafer Mount

    The KF21 Mafer Mount from Kino Flo is a handy way to provide power to the Celeb 250 LED, Diva-Lite 20/30 LEDs, FreeStyle 31/21 LEDs, Select 20/30 LEDs and Celeb 850 LED lights. The mount attaches to a stand via the mount's 5/8" receiver and a Mafer or similar clamp. The LED light itself, can then attach to the stand's 5/8" pin. The 28.8V K21 battery attaches to a housing built into the mount and the included 3-pin, 3' XLR output cable is then attached to the light. The arrangement keeps the battery off the floor and places it and the stand in line with the light and its controls.
