These notes will help you to install the Flexible Open Source firmware on the TSDZ2 motor controller and on the following displays:

  • Bafang 850C (320*480 pixels, 3.2 inches color LCD)
  • SW102 (64*128 pixels, 1.3 inches black and while LCD, with bluetooth)
  • KT-LCD3 (monochrome segment display)
The recommended displays are Bafang 850C and SW102 because they have much more memory compared to KT-LCD3 (and because of that has more features) and flexibility in showing information.

IMPORTANT NOTES:
  • Installing the open source firmware will void your warranty of the TSDZ2 and displays.
  • We are not responsible for any personal injuries or accidents caused by use of this firmware.
  • There is no guarantee of safety using this firmware, please use it at your own risk.
  • We advise you to consult the laws of your country and tailor the motor configuration accordingly.
  • Please be aware of your surroundings and maintain a safe riding style.

Introduction

Although this displays signals are compatible with TSDZ2 motor controller, they have different connectors so you will have to connect this display cable wires to the original TSDZ2 display cable by yourself, but this is a simple soldering task.

If you are afraid to do the installation by yourself, you can ask at a local ebike shop as they should easily be able to do it, as the technical difficulty is small.

Jbalat did a series of videos explaining how to install the firmware (please note that some links on the video may be out of date).

NOTE: For the TSDZ2 motor configurations found on online shops (36V, 48V, 52V, whichever power in watts, with throttle or without) the motor controller is just the same. The only relevant difference is brushless motor inside, that there are only 2 different: 36V and 48V motor (52V systems use the 48V motor).
