We've been testing DC systems here at Dedolight California for the best solution to power dedolight and Profound systems remotely, and this one stands out among the weeds. It allows us to use a single system to power a myriad of different devices which greatly minimizes how much gear we need to carry. This is the intersection of quality and convenience with the SWIT PB-H260A (260Wh, Gold mount), or the PB-H290S (290Wh, V-lock).
Many high power film devices are designed with 22-33.6V high-power input to reduce current. If a standard Gold mount battery is used with high-voltage sources it will damage normal 14.4V voltage devices. The SWIT innovative “Bi-voltage” battery systems, in V-lock or Gold mount options, output11-16.8V normal-voltageor22-33.6V high-voltagewith automatic recognition, switching, and is compatible for all normal voltage chargers. The PB-H290S supports 6A fast charging with the SWIT S-3812S fast charger to save more than 50% charging time; can be charged from 0 to 80% after 2 hours 15 minutes, and fully charged within 4 hours.
This kind of flexibility is exactly what we are all about, and it's backed by one of the best brands in the biz.

Integration with 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. This 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.
* KA-A20S Plate: CNC metal housing, High load power pins, Provides D-tapx2 (16V), 2-pin LEMO (16V), USBx1 (5V/2A) 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 effectively, and protect power pins and ensure the reliability. You can easily put on a “Magic Sticker” on the particular position of all standard V-mount plates, then PB-H290S battery can recognize and auto switch on 22-33.6V output mode. 290Wh Capacity PB-H290S consists of 24pcs high class 18650 battery cells, and reaches 290Wh high capacity, supports Max 200W constant power output, and 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 Fast Charging Using SWIT S-3812S fast charger PB-H290S supports 6A fast charging by SWIT S-3812S fast charger to save more than 50% charging time; it can be charged from 0 to 80% after 2 and half hours, and fully charged within 4 hours 15 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.
Using 14.4V (11-16.8V) output mode, D-tap output 11-16.8V and Max load 120W/10A
Using 28.8V (22-33.6V) output mode, D-tap output constant 16V and Max load 50W/3A
Digital Power Indicator 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 The PB-H290S has an innovative dual housing structure: the inner cell cage and outer anti-shock housing with rubber covers. The new structure makes the battery quite strong and anti-shock. The battery can survive from 1.5 meters any angles drop-off.
