For power-hungry ARRI cinema cameras requiring 24V power, the Indipro B-Mount 298Wh 28.8V Lithium-Ion Battery can get it done. This high-capacity B-mount battery mounts on a B-mount battery plate on cameras such as the ARRI ALEXA LF, ALEXA, AMIRA, or ALEXA Mini, as well as the Phantom Flex 4K high-speed camera.

The battery's 298Wh capacity and 28.8V output are sufficient to power your cinema camera for long shoots. One USB-A, one USB-C, and four D-Tap accessory outputs can be used to power a light source, monitor, recorder, or other gear. The USB-C port can also be used to charge the battery using a separately available PD fast charger. A 5-LED gauge displays the battery's remaining power.
