I have the HDMI output module and I am very pleased with the quality of the picture on a Philips HDMI monitor. I am using a 5 meter HDMI standard to mini cable which means I can connect the RC to the monitor and fly from outside my study, with the monitor plugged into the mains. However, I would like to take the monitor out into the field. I have a few deep cycle batteries which I use to charge my batteries when I am out on a long shoot, and it occurred to me that I could drive the monitor from one of those as well. This will help enormously with search and retrieve type missions for example. I am considering putting the monitor up in the back of my SUV, and with a 5 meter cable I will be able to easily move around the the back of the SUV while flying, and the monitor will be out of the sun's glare. Is it safe for the monitor? Are there other considerations?
