The chart below shows the need to regulate the output voltage of the unit to ensure against over or under charging your battery over a wide range of temperatures. Using your At-the-Battery Sensor will accomplish this better than any other known method. Please note: Table is for STANDARD AVIATION setting. The GILL 7000 SERIES, ODYSSEY and HAWKER setting provides charging voltage of 29.4V and float of 27.2V at 25°C/77°F. The CONCORDE setting provides charging voltage of 28.2V and float of 27.0V at 25°C/77°F. All settings are properly temperature compensated.
