Telemetry and settings

The battery switch is compatible with JETIBOX/SMART-BOX and you can use it for programming. The JETIBOX menu is divided into three sections:

  • Actual values – displays the latest telemetry values (current, voltage, capacity, temperature) including minimums and maximums.
    • The main screen shows the device temperature with the voltage and current of the active battery. If the charging is enabled and active, the “CHG” status is displayed.
    • In the Capacity screen, you can press left+right buttons simultaneously to reset the measured capacity. The asterisk marks the active battery input.
    • The “Time” screen shows a cumulative time of the primary and secondary battery input, meaning how long each source has been used to power the device.
    • Reset Min/Max - simultaneously press left+right buttons to reset all minimums and maximums.
  • Settings – basic settings of the sensor
    • Language – you can choose the language of the JETIBOX screen.
    • Switch type (Touch/Electronic/Mechanical/Hall/Button). You can specify which type of switch will be used to turn the device on and off. If you choose the Electronic option, you can connect any electronic switch with voltage output (e.g. magnetic or radio-controlled switch).
    • Touch sensitivity – if the integrated touch switch is used, you can increase its sensitivity by editing this value. Please note that increasing the sensitivity will allow you to install the battery switch directly inside thicker fuselages. On the other hand, this will also make the touch sensor more vulnerable to erroneous inputs.
    • Voltage threshold – specifies the switchover voltage for B1 and B2 inputs, see the Battery Backup Function chapter.
    • Voltage hysteresis – this parameter is taken into account when switching supply from one battery to the other and back. It is important to keep the hysteresis low to enable equal discharging of batteries. On the other hand, it must be high enough to prevent fast battery switching under load. There are three possible options:
      • High hysteresis (LiPol) – approx. 1.2 V. This is a default and recommended option for LiPo(LiIon)/LiPo(LiIon) or ESC-LiPo(LiIon) combination. This option can be used together with batteries of high internal resistance.
      • Medium – approx 0.5 V. This option can be used for equal discharging low-resistance LiPol(LiIon) batteries.
      • Low (LiFe) – approx. 0.3 V. Use this option together with low-resistance LiFe batteries.
    • Capacity reset – Setting up this parameter will specify at which moment the capacity is reset to zero. Available options:
      • Power-On (default) – capacity is reset every time after connecting the battery.
      • Voltage-Change – capacity is reset after connecting the battery with a different voltage (by 15 % or more). This way the sensor may distinguish between charged and discharged battery.
      • Manual – capacity is never reset automatically.
    • Charging – you can enable the charging function for 2S LiIon/LiPo or 2S LiFe secondary battery (B2).
    • E1/E2 Function – choose the preferred function of the two extension ports (possible options: EX/EX Bus telemetry input, digital input, digital output).
    • E1/E2 Out Channel – if the digital output function is selected, it is necessary to choose the appropriate channel.
  • Service – In this menu you can view the device version and reset it to the default factory configuration.
