Today I realized how many batteries have to be ready charge and working on each flight on a 2 operator setup... 1 main copter 2 pilot video down link 3 gimbal Radians 5.8 transmitter HDMI down 4 main camera 5 pilot radio 6 pilot video FPV monitor 7 pilot FPV video receiver 8 Camera op radio 9 Camera op FPV monitor 10 cam operator 5.8 down link receiver 11 iPhone for backup timer Am I missing batteries or I have too many??
For the ground station(s) I run one battery for each and use BEC's or RECOMS to lower voltage to the individual devices. Add in the car battery to get you to and from the launch point and your list will be complete.
Welcome to the Anthropocene Age of the Tyranny of the Battery. You omitted the battery for your laptop and, if you want record the FPV on a DVR, that one too. For the ground station equipment (excepting the Graupner and Futaba Tx which I don't think can be operated whilst charging), I use a Lithium Iron Phosphate battery (LiFePO4) and a "Hot Box" power distribution bar: http://www.remoteaudio.com/hotbox_v2/ which has four-pin XLR connectors. Pin 1 is battery, pin 4 is ground. I can then arrange for appropriate BECs to be wired into circuit to give 5volts. Andy.
