Add a Gold mount plate to your power-hungry ARRI ALEXA LF, 65, or SXT camera with this 26V Gold Mount Plus Sharkfin Dual Battery Mount from Wooden Camera. The Gold mount plus Dual allows you to mount two batteries and attaches directly to the camera pogo connectors, providing power from large 26V block batteries.
The plate features a 2-pin Fischer input, which prioritizes the external DC source to drain before the onboard battery, and then it hot-swaps to the onboard battery when that source is drained. There are also two 15V regulated D-Tap outputs to power additional accessories. The plate supports battery hot-swapping, and it features an OLED screen that shows voltage and battery capacity information. A safety feature will cut power to the D-Tap ports if voltage exceeds capacity threshold.
