Categories: Kino Flo LED


This new Kino Flo/Block KF21 Battery System has been designed especially for the Kino Flo LED systems, truly maximizing their portability. Currently, this little power system is compatible with the Celeb 250 LED DMX, Diva-Lite 20 & 30 LED DMX, FreeStyle 31 & 21 LED DMX as well as the Select 20 & 30 LED DMX units. Capable of pumping out 28.8V (20-34VDC), it can power the compatible Kino Flo units, at full brightness, for about 70 minutes. The included Dual Fast Charger is designed to fully charge one Kino Flo/Block KF21 Battery in 1.5 hours, indicated by a stable glow of all three of the charger’s LEDs. Not only does the KF21 charge in less than half the time of a Lithium battery, but it also isn’t affected by the same travel restrictions.
