KA-B21S conversion plate allows you to adapt V-mount batteries to the cameras with B-mount plate, like ARRI ALEXA 35, Blackmagicdesign URSA CINE. KA-B21S doesn’ t change battery voltage. The B-mount side outputs the same voltage of V-mount batteries.
28.8V Battery to Power ALEXA35
SWIT Bi-voltage V-mount battery recommended Use SWIT PB-H290S 14.4V/28.8V Bi-voltage V-mount battery, the KA-B21S plate will active 28.8V high voltage output mode of PB-H290S, and provide 22-33.6V voltage to power the B-mount cameras ALEXA 35 and BMD URSA CINE. * The PB-H290S can output 14.4V for all regular V-mount devices, and compatible with all regular V-mount chargers.
V-mount to Power ALEXA35
26V/28.8V V-mount Batteries Compatible You can use pure 26V or 28.8V high voltage V-mount batteries to power ALEXA 35 by KA-B21S conversion plate. SWIT HB-C420S 28.8V 420Wh huge capacity V-mount battery is a nice solution to provide extreme long duration to ALEXA 35.
