B-mount to V-mount 28.8V
KA-S21B conversion plate is to use the B-mount
battery to power V-mount cameras or other devices.
The ID pin of the B-mount plate is 28.8V, so the
V-mount output voltage is 21.6-33.6V range. Please
make sure the V-mount cameras or devices support
up to 33.6V input.
RED V-Raptor XL Power
The RED V-Raptor XL needs 28.8V high voltage
power input to enable the various DC out
sockets on the camera.
Use B-mount batteries and the KA-S21B plate
will power RED V-Raptor XL at 21.6-33.6V, to
active the full functions of the camera, and
avoid misuse on other cameras.
Power RED XL by B-mount Batteries
Use SWIT B-mount batteries, including HB-A290B, BIVO-98, BIVO-160,
BIVO-200, BIVO-290, and the KA-S21B plate, to power RED V-Raptor XL
at 21.6-33.6V high voltage.

We provide a 1-year conditional warranty, and the following damages/issues are not covered under warranty:
(1) Any damage or malfunction caused by use, maintenance, or installation not in accordance with the User Manual's instructions, including improper battery insertion or removal, incorrect polarity connection, exposure to moisture or conductive debris, or disassembly/repair without authorization of SWIT.
(2) Any damage caused by using third-party batteries, power sources, or accessories that do not comply with the recommended electrical specifications (e.g., voltage, current, or contact pin configuration), including but not limited to electrode overheating, melting, arcing, or short circuits resulting from incompatible battery design or poor battery quality.
(3) Any damage caused by irresistible factors (such as earthquake, fire, lightning, flood, etc.) or human factors including dropping the plate, impact damage, forced battery removal at incorrect angles, or insertion of damaged or deformed batteries.
(4) Any damage or malfunction not caused by the product's design, workmanship, or manufacturing quality — including normal wear and tear of spring-loaded electrodes, contact pins, locking mechanisms, or surface finish scratching.
(5) Electrode breakage, bending, or deformation resulting from violent use, excessive force during battery attachment or detachment, or improper alignment of the battery onto the plate is specifically excluded from warranty coverage. This includes snapped, crushed, or pushed-in contact pins caused by user mishandling.
(6) Electrical or thermal damage (including melted plastic around electrodes, burnt contacts, or discoloration from heat) that is determined to be caused by a third-party battery's internal short circuit, over-current draw, overheating, or defective connector design shall not be covered under this warranty. Such conditions are the responsibility of the battery manufacturer.
