3 in 1 Low Voltage Alarm BB Buzzer Tracer Signal Loss Alarm 2-6S Lipo Support for RC Drone FPV Racing Precise details: Introduction: Introduction:IthasLipoVoltageTester,BuzzerTracerandUncontrolledSignalLossAlarmfunction. Bulit in super bright 5050 LED Light indicatior and Double buzzer. Small Size, Light Weight and alarm sound clearly. Specification: WorkingVoltage:5.2-26VDC,2-6SLipo StaticPower:10mA Max.WorkingCurrent:120mA(ledflashingandbuzzer) Inputvoltagecut-offsetting: 3.4-3.7v/cell ( Red LED Indicator) Double Buzzer: 85dB + 85dB Super Bright Blue 5050 LED, 0.2W Size:20x30x6mm Weight: 7g Function 1: LipoVoltageTester Itcanmonitorthereal-timetotalvoltageof2~6SLiPoinusing,oncethevoltagedropstothesetcut-offvalue,itwilltriggeranalarmprompt.Voltagecut-offvaluecanbesetwithintherange:3.4V~3.7V/Cell. 1.1 When the LiPo battery is connected, if the total voltage of the battery pack is in the following range, the 3 in 1 will automatically determine the number of battery pack units. 7.4-8.6V:2cellsLiPo 11.1-12.9V:3cellsLiPo 14.8-17.2V:4cellsLiPo 18.5-21.5V:5cellsLiPo 22.2-25.8V:6cellsLiPo Itwill sound "Bi" and the red LED will light up, indicating the previously saved cut-off voltage value. - Long press the button for 3 seconds to enter the cut-off voltage value setting - Short press the button to select the appropriate cut-off voltage value within 3.4 ~ 3.7V (red LED indication) - If there is no button action within 10 seconds, the current value will be automatically saved and exited During the discharge process of the LiPo battery, the three-in-one will monitor the total voltage of the battery pack in real time. If the total voltage is lower than "cut-off value × number of units", an alarm will be triggered, the blue LED will flash, and the buzzer will continue "Bi..Bi..Bi..Bi...." If the total voltage rises back above "cutoff value x number of cells", the alarm is suspended. 1.2 When the LiPo battery is connected, if the voltage of the battery pack is not within the above range. The 3-in-1 will prompt "Bi..Bi..Bi" and all 4 red LEDs are on, please check whether the voltage of the battery pack is too low and unsuitable continue to use. Function 2: Buzzer Tracer Just plug the Y cable (provided in package) into an Aux channel of the receiver (such as Gear). Regardless of turning the channel switch in any direction, the buzzer will sound "BiBiBiBiBi" five times, and the blue LED will flash. This function must require the receiver to have a signal, and the alarm prompt is triggered manually. Function 3:Outofcontrolalarm Firstly, turn on the transmitter, and using Y cable to connect it to throttle channel of the receiver, and then power on the receiver. This function alarm is a passive alarm. When the receiver is powered on, the alarm will be triggered automatically in the following situations: - Turn off the transmitter first, if it is not turned on within one minute, the receiver will not receive a signal, and an alarm will be triggered. - When the transmitter is turned on, if no joystick movement is detected within one minute, or there is no signal change, an alarm will be triggered. The alarm prompt is a continuous "BiBi...BiBi...BiBi..." accompanied by a blue LED flashing. After the alarm is triggered, if the receiver receives a signal change, it will be automatically released.
