BlueShape Gold Mount DC 21V 220W 3-Stud Adapter for ARRI ALEXA LF Camera

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 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 optimize the load on the battery with an efficiency not inferiro to 95%.Also, providing approx 21V to the camera, MGAL-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 BLUESHAPE plate also provides digital communication from the battery to the camera for BLUESHAPE batteries. The user will see the RSOC (relative state of charge) in the camera display, data not available with batteries other than BLUESHAPE.The demands of the camera have inspired the our team to develop the ideal 3-Stud battery for use with theARRI ALEXA LF: the GRANITE HDplus series.Based on the data provided by the camera manufacturer (see below), when using MGAL-LF with these batteries, a user can expected the following runtimes:• BG100HDplus: from 46 to 35 minutes• BG190HDplus: from 93 to 69 minutes• BG290HDplus: from 139 to 105 minutes
