The Switronix PowerBase Battery is a fantastic solution for the anemic battery that comes included with the Sony A7 series cameras. This unit will last about 5-6x the normal Sony NP-FW50 Battery, giving you about 5 hours of runtime. It uses a big 14.8V, 77Wh V-Mount battery that connects to the bottom of an A7 series camera using a small quick release plate. The PowerBase system uses a dummy battery with a cord that plugs right into where a normal battery lives in the A7 series camera. The battery door has a convenient rubber hole that you can open to run the cable outside the camera. The PowerBase also has 2 P-tap outputs if you are running other accessories and a convenient battery life gauge. You can mount the system using any of the 3 1/4"-20 threaded female ports on the sides and bottom of the PowerBase.
Please note: The battery reading in the camera when using this product may show less capacity than the battery actually has. Use the LED indicator on the side of the Switronix battery as a gauge of capacity remaining, NOT what the camera displays.
