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Jbalat did a series of videos explaining how to install the firmware (please note that some links on the video may be out of date).

NOTES:

  • Motor configurations: 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).
  • Motor max power without damage by heating: the motor can handle only about 8 or 10 amps continuously (10 amps with a 52V battery is 520 watts) otherwise it will heat up fast and damage permanently the motor. Peaks of 18 amps can be used, like at startup or for short time but it is advised to install the motor temperature sensor so the firmware will be able to protect the motor, by reducing the motor current as soon the starts heating after a defined threshold.

Steps for the installation

Note: before start, please first read all the steps to find the tools you will need to have.

  1. Buy the display of your preference: buy Bafang 850C, buy SW102 or buy KT-LCD3.
  2. Flash the firmware on the display: flash Bafang 850C, flash SW102 or flash KT-LCD3
  3. Wire display to TSDZ2: wire 850C, wire SW102 or wire KT-LCD3
  4. Flash the firmware on TSDZ2
