14.4V/28.8V Bi-Voltage
For ALEXA LF/65 and all normal cameras
The great solution to power ARRI Alexa LF/65
high voltage cameras: SWIT Intelligent Bi-voltage Battery, which 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 dedi-
cated V-mount plate KA-A20S, PB-H290S battery can
recognize and auto switch on 22-33.6V, to power
Alexa LF/65/SXT/AMIRA.
* KA-A20S Plate:
CNC metal housing, High load power pins,
D-tapx2 (16V), 2-pin LEMO (16V), USBx1 (5V/2A)
Officially Recommended by ARRI

14.4V/28.8V Auto Switching
By “Magic Sticker” on normal V-plates
Beside ALEXA cameras, many Cine Lights are also
designed high voltage input, to reduce current ef-
fectively, and protect power pins and ensure the
reliability.
You can easily put on a “Magic Sticker” on the par-
ticular position of all standard V-mount plates,
then PB-H290S battery can recognize and auto
switch on 22-33.6V output mode.

290Wh Capacity, 250W High Load
PB-H290S consists of 24pcs high class 18650 battery cells,
and reaches 290Wh high capacity.
PB-H290S supports Max 250W constant power output, can
drive ALEXA LF (160W) more on-camera monitors or wireless
simultaneously.
The high load battery will have longer life time than normal
battery if always under full load power.

D-tap Socket
A D-tap DC output socket is equipped on the top side of the
battery pack, to power the other on-camera equipment together.
Under 14.4V (11-16.8V) output mode, D-tap output
11-16.8V and Max load 120W/10A;
Under 28.8V (22-33.6V) output mode, D-tap output constant 16V and Max load 50W/3A;

Digital Power Indicator
8-LED remaining time read
When battery is discharging:
Press "Power Check" button, Upper 4 LEDs display remaining working hours, and Lower 4 LEDs display remaining working minutes, under current output power. The LED will flash when remaining time is less than 15 minutes to remind changing battery.
When battery is charging:
Upper 4 LEDs flashing constantly, indicates the real-time capacity percentage 25%, 50%, 75% and 100%.
When battery is free:
Press "Power Check" button, Upper 4 LEDs light up, to indicate the remaining capacity percentage 25%, 50%, 75% and 100%.

Strong 1.5m Drop-off Proof
Dual housing + Rubber cover
PB-H290S has innovative dual housing structure: the inner cell cage and outer anti-shock housing with rubber covers. The new structure
makes the battery quite strong, anti-shock. The battery can survive from 1.5 meters any angles drop-off.
