The T75 is a high performance digital dual battery backer with advanced telemetry features. It contains a
charging circuit and touch switch functionality. The device is ideal for mid-size models where high-voltage servos
are used without voltage stabilization.
T75 is suitable for models equipped either with dual receiver batteries, or with ESC battery eliminator circuit
(BEC) used as a primary power source, combined with a small backup battery. The device prefers its primary
battery input, while in case of voltage drop it automatically switches to the secondary input. The charging circuit
may be optionally enabled to charge the secondary battery from the primary input/BEC.
T75 is designed to turn on/off the electronics in your model, it can replace a mechanical switch as well. The device
remembers its last operating state, and if the battery is accidentally disconnected, the T75 will automatically boot
up again as soon as the battery is connected again.
Features
Intelligent dual battery backer/multiplexer with configurable voltage switchover threshold.
Touch switch function. Optionally, the possibility of connecting a magnetic, mechanical or electronic
switch or button.

  • Page 1 T75 is designed to turn on/off the electronics in your model, it can replace a mechanical switch as well. The device remembers its last operating state, and if the battery is accidentally disconnected, the T75 will automatically boot up again as soon as the battery is connected again.

  • Page 2: Installation

    Optional mechanical/electronic switch connection: If using the device in combination with R3/RSW Wireless Switch you have to change the T75 setting from "Touch" to "Electronic" switch option. For long- term storage, backup battery has to be disconnected due to constant load of the R3/RSW Wireless Switch.

  • Page 3: Battery Backup Function

    ATTERY BACKUP FUNCTION The T75 generally uses its primary battery input B1 as a main power source. If the B1 voltage drops below the configured Voltage threshold value, it can switch to the B2 input. In such case the source with higher voltage will be used.
  • Page 4 Make the status LED visible from outside the fuselage and put the “touch” sticker on top of the touch surface.  Connect the receiver battery to the T75 and briefly touch the button. Status LED should blink once. If not, please increase the touch sensitivity parameter in the configuration. ...
  • Page 5 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 T75 directly inside thicker fuselages. On the other hand, this will also make the touch sensor more vulnerable to erroneous inputs.
