Key Benefits - Quick on-device configuration of battery type and voltage with a simple two-step operation. - Clear LED feedback lets you see exactly when you are selecting battery type and when you are adjusting voltage. - Settings are saved with a 2 second hold, and the display automatically returns to Power Status after up to 5 seconds of inactivity. - No tools required, streamlined for field adjustments and routine maintenance. - Keeps your configuration in memory for consistent operation across power cycles. How it works - Enter setting state: Hold the key for 2 seconds to enter the setting state. The Mode Light (Battery 1 Type) flashes and the Number Light stays on. Briefly press the key to select the battery type. - Set voltage value: After confirming the battery type, hold the key for 2 seconds to enter Number 2 / Voltage setting. The Mode Light remains on and the Number/Voltage Light flashes. Use the button to set the battery string number or voltage; please refer to the above table option settings for details. - Save and return: After setting, hold the key for 2 seconds to save the data and return to the 4 Power Status display. Or wait 5 seconds for an automatic return. - Controls: The button is used to set the battery string number or voltage; please refer to the above table option settings for details. Key Attributes - Function: Battery type selection and voltage setting via a single button with two-step operation. - Compatibility: Works with configurations that use Battery 1 Type and corresponding Number/Voltage settings as indicated. - Indicator lights: Mode Light for battery type and Number/Voltage Light for selection progress. - Size and build: Compact user interface designed for easy handling in the field. - Performance: Fast, reliable save and automatic return to Power Status for continuous monitoring. Use scenarios - RC hobby projects: Quickly configure battery type and voltage for models such as cars, boats, or drones to match your ESC and power requirements without tools. - Portable power setups: Adjust battery string numbers and voltages on modular packs to optimize run-time and safety for field use. - Field maintenance: Technicians can verify and update battery configurations on compatible equipment during service calls, ensuring correct operation after installation or replacement. Notes - The button is used to set either the battery string number or the voltage; consult the above table for exact option values and compatibility. - After saving, the device returns to the Power Status display (4 Power Status) or auto-returns after 5 seconds of inactivity.
