To answer a few things here. The battery voltage regularly will vary from 12 volts to as low as 3-4 volts depending on the load and state of charge. The 2009 game is unlikely to draw the battery so low during a match but in any design, expect at least a 5 volt variation in the unregulated supplies. IFI control systems used an eight volt trip point before switching to the backup battery and disabling the PWM outputs. Eric can correct me but I believe the PD 24 volt output will be maintained down to a sustained battery voltage of 4.5 volts as well as the 12v to 12 volt (for the wireless) and the five volt (for the camera) power supplies.
