SWIT PB-H290S 290Wh Intelligent Bi-voltage Battery Pack.
14.4V/28.8V Bi-Voltage
For ALEXA LF/65 and all normal cameras
The ARRI Alexa LF / 65 require on-board battery input voltage 19.5-34V only, and the normal 14.4V (11-16.8V) batteries are no longer compatible.
The existing 26-28.8V high voltage batteries can power Alexa LF/65, but the high voltage with the same physical connectors will surely damage other normal cameras.
A better solution is to use normal 14.4V battery with a DC boost plate, but the current between battery and V-plate will get quite high with 160W load and 14.4V voltage, and will melt the battery pins.
Now you will have a great solution for Alexa LF/65: the SWIT Intelligent Bi-voltage Battery, can output both 11-16.8V normal voltage and 22-33.6V high voltage, with auto recognition and switching by the dedicated V-mount plate, compatible with Alexa LF/65 and all other normal cameras and devices, with no risk of misusing.
14.4V/28.8V Auto Switching
By Alexa dedicated plate KA-A20S
The Bi-voltage battery PB-H290S output normal 11-16.8V voltage as default, you can attach to any normal V-mount
cameras or other devices, and any normal voltage chargers.
Use the ARRI ALEXA dedicated V-mount plate KA-A20S, PB-H290S battery can recognize and auto switch on 22-33.6V, to power Alexa LF/65/SXT/AMIRA.
