The KF21 battery can power 28.8V (20-34VDC) applications. Run time for Kino Flo products listed above is approximately 1 hour and 10 minutes at full brightness. When fixtures are dimmed, the battery will last longer. Charge time is only 1.5 hours versus Lithium batteries that take approximately 4 hours to fully charge. Unlike lithium batteries, the Kino Flo/BlockBattery is also travel friendly with no travel restrictions.
In addition to powering 28.8V, battery adapters may be used to access 14.4V to be used with products with 14.4V input. It’s like having two batteries for the price of one!
