SWIT S-8113S 160Wh High-Load V-Mount Battery

A conventional lithium-ion block gives about 100W and 8A, which is fine for an ENG camera. An ARRI ALEXA draws around 85W on its own, and once a monitor and a light are added the total sits above what a normal pack can supply without shortening its own life.

The S-8113S uses high-load cells rated for a maximum 150W and 12A constant output, so a cine camera and its accessories run off one 160Wh battery without the pack degrading under sustained full draw. It is available on V-Mount as the S-8113S and on Gold Mount as the S-8113A.
