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.

6A Super Fast Charging

Using SWIT super fast charger

PB-H290S supports 6A fast charging by SWIT S-3812S or PC-P460S super fast charger, to save up to 60% charging time, can be charged from 0 to 80% after 2 and half hours, and fully charged within 3 hours 50 minutes.

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.

ARRI Alexa LF/65 requires batteries that provide an input voltage of 19.5-34V, so normal 14.4V (11-16.8V) batteries are not compatible. High voltage 26-28.8V batteries can power the Alexa LF/65, but that voltage would damage all other normal cameras that need 14.4V. This intelligent two-voltage model, which can supply a normal voltage of 11-16.8V and a high voltage of 22-33.6V with self-recognition and automatic voltage selection for V-mount plate, is a great solution and avoids the consequences of misuse. Compatible with Alexa LF/65 and all other cameras and devices.

By default it provides 11-16.8V so that V-mount cameras and normal voltage devices can be fed. Using ARRI ALEXA's KA-A20S board, you can recognize and auto-select the 22-33.6V output voltage, to power the Alexa LF/65/SXT/AMIRA. A "magic sticker" can easily be placed on the proper position of any standard V-mount plate and the battery will automatically recognize and adjust to the 22-33.6V output voltage.

It is composed of 24 high-end batteries type 18650 and reaches 290Wh high capacity. It provides up to a maximum constant output current of 200W, and can power the ALEXA LF (160W) and also one camera monitor or wireless transmitter at a time. This high-charge battery can have a longer life than normal batteries if always operated at full power.

In addition, it supports fast charging at 6A with the SWIT S-3812S fast charger, which saves more than 50% of charging time. It can charge from 0 to 80% after two and a half hours and the full charge takes 4 hours and 15 minutes. A D-tap connector can be found at the top of the battery to feed camera accessories at the same time. When the battery is being used you can press the "Power Check" button so that the top 4 LEDs show the hours and the bottom 4 LEDs show the remaining minutes of operation. The LEDs will flash when there is less than 15 minutes of operation remaining, remembering to charge the battery.

It has an innovative dual-structure housing: internal protective housing and external anti-shock housing with rubber covers. The new structure provides robustness to the battery against possible blows up to 1.5 meters drop height.
