48V 1500W KT Motor Controller with LCD3 Display – 3-Phase BLDC

The 48V 1500W KT motor controller with LCD3 display is a matched electronic control unit and handlebar display for electric bikes, electric scooters and other light electric vehicles running three-phase brushless DC (BLDC) motors. System voltage is 48 V and rated power reaches 1500 W. The controller manages the motor phases, while the LCD3 screen shows ride data and opens the settings menus.

This pairing suits e-bike and e-scooter conversion builds as well as repairs. It supports 3 / 5 / 9 assist levels and PAS pedal assist, so power delivery follows your cadence rather than arriving in one step. Wiring uses the KT connector standard, which keeps assembly straightforward when the pin layout matches.

Note that the motor, battery, throttle and PAS sensor are separate components. They are not included here. Also important: 1500 W exceeds the 250 W and 25 km/h limits that apply to EU pedelecs (EPAC). Therefore this system is intended for off-road use, private property, or a registered L-category vehicle.

Key Benefits

• 48 V / 1500 W rating – built for 48 V systems driving a three-phase BLDC motor up to 1500 W.
• 3 / 5 / 9 assist levels – pick a power profile that matches your riding style and route.
• PAS pedal assist support – assistance engages as you pedal, so output stays smooth.
• LCD3 handlebar display – speed, distance and battery status appear in one place (depending on configuration).
• P/C/L parameter menus – set wheel diameter, speed limit and the number of assist levels directly on the screen.
• Three-phase BLDC compatibility – works with common hub motors used in e-bikes and e-scooters.
• Built-in protections – short circuit, overload and over-temperature safeguards, depending on configuration.
• Plug-and-play wiring – no soldering required when the connector pin layout matches.

Who Is This For

This set fits electric bikes, electric scooters and other light electric platforms with 48 V power and a three-phase BLDC motor rated up to 1500 W. The one requirement is a compatible wiring harness with a matching connector pin layout. Check that first, before anything else.

Builders choose it most often when assembling an e-bike themselves from a hub motor and a battery pack. It is equally useful as a replacement when an older controller or display has failed. In addition, the LCD3 screen works with other KT controllers of the same generation, provided the connectors line up.

However, the LCD3 uses a closed KT data protocol. As a result, it does not communicate with Bafang, Sabvoton, Votol or Fardriver controllers. Plan your build around KT-series electronics if you want this display to work.

Technical Specifications

Why Choose This KT Controller and LCD3 Set

The controller and display ship as a matched pair. Consequently, you avoid hunting for a screen whose protocol agrees with your controller. Connectors follow the KT standard, which shortens assembly time noticeably.

KT-series controllers are sine wave units. That waveform turns the motor more quietly and more evenly than square wave control. For this reason builders frequently select them for hub motor conversions, particularly on bikes ridden daily.

The second strength is configuration depth. The LCD3 P, C and L parameter menus let you change wheel diameter, the number of assist levels and throttle behaviour. Therefore the same controller adapts to different wheels and motors without hardware changes.

Installation Tips

• Before connecting anything, verify the pin layout on every plug: motor, PAS sensor, brake cut-off signal, throttle and display.
• Set the correct wheel diameter in the LCD3 menu so speed and distance readings stay accurate.
• Choose your assist level count in the menus once the basic setup runs correctly.
• Confirm your battery and wiring are rated for the current a 1500 W system draws.

Frequently Asked Questions

Which motors does this controller work with?

• Three-phase brushless DC motors rated up to 1500 W.
• System voltage must be 48 V.
• Hub motors on e-bikes and e-scooters are the typical match.

Does the LCD3 display work with Bafang or Sabvoton controllers?

• No. The LCD3 uses a closed KT data protocol.
• It does not communicate with Bafang, Sabvoton, Votol or Fardriver units.
• It does work with other KT controllers of the same generation when connectors match.

What is included in the set?

• The motor controller and the LCD3 display.
• The motor, battery, throttle and PAS sensor are separate components.

Can I use this on public roads in the EU?

• 1500 W exceeds the 250 W and 25 km/h EPAC pedelec limits.
• Use is intended for off-road riding, private property, or a registered L-category vehicle.

Do I need to solder anything during installation?

• No, installation is plug-and-play when the connector pin layout matches.
• Check every plug before powering the system up.

What can I adjust on the display?

• Wheel diameter, speed limit and the number of assist levels.
• Throttle behaviour, through the P, C and L parameter menus.

How does pedal assist work here?

• A PAS sensor triggers assistance as you pedal.
• You then select 3, 5 or 9 assist levels to shape power delivery.

Why pick a sine wave controller?

• Sine wave control turns the motor more quietly than square wave control.
• Power delivery feels smoother, which suits hub motor conversions.

Whether you are building an e-bike from a bare hub motor or replacing failed electronics, this 48 V KT controller and LCD3 pairing gives you a tested combination with deep configuration options. Confirm your harness connectors first, set the wheel diameter, and your 1500 W three-phase build is ready to tune.
