An alternative power solution to use with V-Lock or 3-Stud batteries
The ARRI ALEXA LF® large format camera needs a minimum of 20V to operate properly. This is beyond the specs of a normal 14.4V battery and does not allow the use of a standard battery plate.
BLUESHAPE has designed an efficient battery plate for the ALEXA LF®. This accessory allows a 14V battery to provide the required voltage through a state of the art power converter that optimizes the load on the battery with an efficiency not inferior to 95%.
Also, providing approx 21V to the camera, MVAL-LF can works as a secondary power source when the camera is powered through an external DC source like a block battery or a POWER STATION.

The demands of the
camera have inspired the our team to develop the ideal V-lock battery for use
with theARRI ALEXA LF®: the GRANITE HDplus series.
Based on the data provided by the camera manufacturer (see below), when using MVAL-LF with these batteries, a user can expected the following runtimes:
