SWIT PB-R160S+ 160Wh Heavy Duty IP54 V-Mount Battery

At 160Wh the PB-R160S+ sits right on the airline limit, which is why it is the pack most travelling crews standardise on. Eighteen high-grade 18650 cells give 11.1Ah, roughly six hours on a normal ENG camera or two on an ARRI ALEXA.

The case is the other half of the story: a dual housing with an inner cell cage, an outer anti-shock shell and rubber covers, sealed to IP54 for rain and snow and rated to survive a 1.5 metre drop at any angle. It holds at least 200W and 16A of constant load down to 1 percent capacity, peaking at 245W, so a cine body and its accessories can share one battery. It takes 6A fast charging from a SWIT charger and shows remaining power on a digital display.
