Turns out F&V makes a perfect battery bracket for a standard Sony camcorder battery. It is normally used to power up to 4 of their light panels from one battery. In my application, I can use the same bracket to power my R-300 ring light and my Liliput field monitor. Both will run on one battery but now that I can divide the power between the two of them from one source, I can start thinking about where to mount the battery to help with the balance of the rig…
I did a simple test to see how long one of these aftermarket extended batteries can run with the light at full power and the field monitor on. The R-300 turned off after 55min and the Liliput kept running for a long enough time after that where I stopped counting! So now I know that I have almost a full hour of time with the system before I need to swap out a battery. The only shame here is that my GH2 camera body doesn’t have the same power specs to run on this system!! I think the camera battery may run out before the rest of the rig does (looks like another test in the making). Still, this is a significant step for me to better balance the camera system and get more control over my peripherals.
