The IndiPRO Tools Power Grid for Blackmagic Production Camera 4K, featuring two Sony L-Series battery bays, is a single-clamp rod mount power solution. It supports one Sony L-Series battery on each side and draws power from both simultaneously, allowing a substantial increase in the camera's run-time. The supported DV batteries come in different sizes, some very lightweight, and the Power Grid itself weighs only 0.4 lb, so Power Grid can be set up as a lightweight solution. Batteries are sold separately. Power Grid connects to the camera via a right-angle DC connector on an 18" cable.

The Power Grid requires both batteries to be attached at all times, but it also provides continuous power to the camera's internal battery, keeping it at full capacity at all times, so you can swap the two Sony L-Series batteries for two other ones without the camera powering off. An LED indicator on the Power Grid lights up and remains lit as long as the two Sony L-Series batteries have sufficient power.
