Introduction

ImpulseOSD offers various options to monitor battery voltage and capacity. While ImpulseOSD prefers to use the telemetry data from the highly accurate KISS ESCs it also features a factory calibrated internal current and voltage sensor if no KISS ESCs are present.

Once the battery warning is configured, ImpulseOSD will warn you with a flashing warning just below the center of your screen that it is time to land. Of course it is your choice to set the minimum remaining battery capacity when the warning sets off - default is 30%.

NOTE: Battery monitoring is turned off by default and must be configured first. The correct battery size must be chosen for the battery warning to work properly. Monitoring mAh should always be the preference while voltage should only be the backup (in case one or more cells in your battery have failed).

BF users: Even if you are using KISS ESCs (or BlHeli32), ImpulseOSD will use the internal current sensor by default. To force ESC sensor usage, adjust the CURRENT SENSOR setting as described below.

Battery menu

Hold yaw left form more than two seconds while disarmed to enter the Main Menu. Select BATTERY from the Main Menu.

• SELECT BATTERY: You can configure 4 battery sizes. Use roll to switch between batteries. Use pitch to change battery capacity. Yaw left to go back to the battery menu.
• BATT. WARNING: Turn the battery warning ON or OFF. If turned ON, you will get a flashing warning below the center of the screen after the remaining percentage of the battery capacity configured under BATT. % ALARM has been reached.
• BATT. % ALARM: Remaining battery percentage based on battery selected to show the battery warning. If you e.g. configured a 1000mAh battery and the alarm is set at 30% you will get a warning once the mAh consumed reaches 700mAh.
• VOLT. WARNING: Turn the voltage warning ON or OFF. Will show the total voltage in the bottom center of the screen if it is below the cell voltage configured in MIN VOLTAGE. It will also blink any voltage related OSD items/labels.
• MIN VOLTAGE: Minimum cell voltage for the VOLT. WARNING to go off.
• VOLTAGE CORR: If the voltage seems off from what it should be you can correct it here.
• MAH CORRECTION: If you use a KISS FC or you selected ESC as a CURRENT SENSOR this will lead to a new menu page where you can adjust corrections for each ESC in percent. Otherwise you can correct the internal current sensor by adjusting the percentage. 100% means it stays as it is. 105% would 5% higher. 95% would be 5% lower.
• WATTMETER RESET: If you use the Wattmeter and also the corresponding Icon you can reset the Wattmeter maximum value used for the icon. This is only necessary if you changed from a high consuming power train (motors, props) to a more efficient power train that does not pull as many amps.
• CURRENT SENSOR: We strongly recommend to leave this on AUTO unless you know what you are doing. Changing to SENSOR will force ImpulseOSD to use the internal current sensor, changing to ESC will force ESC telemetry.
• SAVE+EXIT: Save all changes (and also changes made in other menus except the VTX menu) and exit the menu.
• BACK: Go back to the previous menu. Changes are not discarded, but they are not saved until you exit with SAVE+EXIT from any menu.

Battery size quick select

If you like to fly different sizes batteries on the same quad you don't want to go into the menu every single time to change the battery size:

Just hold yaw to the right while disarmed and the quick battery size selection will pop up. Use roll to switch between battery sizes and pitch to increase/decrease battery size.
