SWIT PB-R290A 290Wh Heavy Duty Gold Mount Battery

The PB-R290A is the Gold Mount version of SWIT's heavy duty block: 24 high-grade 18650 cells for 290Wh and 20.1Ah, which is roughly eleven hours on a normal ENG camera or three and a half on an ARRI ALEXA.

What separates it from a commodity pack is the load rating. It holds at least 250W and 20A even at 1 percent capacity, peaking at 305W, with over-current protection at 24A, so a cine camera and a light on the same block will not trip it as the pack empties. The dual housing puts an inner cell cage inside an anti-shock outer shell with rubber covers, rated to survive a 1.5 metre drop at any angle, and a digital display reads out remaining power. It supports 6A fast charging.
