Obarter D5 Electric Scooter 48V FOC Sine Wave Dual Controllers (A & B) & LCD Display Throttle Kit
Restore the raw dual-motor acceleration and refined throttle control of your high-performance electric scooter with the genuine Obarter D5 48V FOC Sine Wave Dual Brushless Controllers & Color LCD Display Throttle Kit. Engineered specifically as direct factory replacement electronics for the Obarter D5 5000W Dual-Motor Electric Scooter (Model SH928-D5), this system delivers smooth, surge-free power delivery and whisper-quiet motor operation.
Featuring advanced Field-Oriented Control (FOC) Sine Wave technology, each controller is rated at 48V 35A continuous output with a formidable 45A peak limit. Working in synchronized harmony, Controller A (Front Motor) and Controller B (Rear Motor) deliver a massive combined peak current of 90 Amperes for explosive hill-climbing torque, high-speed stability, and responsive low-level electronic braking.

Key Highlights & Technical Superiority
- Factory Original D5 Architecture: Precision-calibrated for the Obarter D5 chassis with exact plug-and-play harness connectors, yellow XT60 power plugs, and heavy-duty motor phase ring terminals.
- Silky-Smooth FOC Sine Wave Commutation: Eliminates the harsh step-throttle shudder and loud acoustic resonance typical of square-wave controllers, extending motor and battery lifespan.
- High-Power Dual Output: 35A continuous (45A peak) per controller channel, providing up to 90A combined dual-drive output to effortlessly conquer steep off-road trails and steep city inclines.
- Integrated Battery Guard: Built-in 39V ± 0.5V undervoltage protection prevents over-discharging your 48V lithium-ion battery pack.
- Ergonomic Round Color LCD Cockpit: Full-color circular digital gauge with integrated thumb accelerator trigger, showing real-time speed, battery level, trip meter, and speed mode settings.
- Rugged Extruded Heat Sink Cases: Both controllers are housed in deeply grooved aluminum alloy enclosures for rapid passive thermal dissipation during sustained high-speed rides.

Available Component Options
1. Full Powertrain Kit (Controllers A + B + Display)
Includes Controller A (Front), Controller B (Rear), and the matched round color LCD display throttle. Strongly recommended if upgrading or replacing non-matching controllers to avoid communication errors.

2. Dual Controllers Pair (Front A + Rear B)
Includes both factory 48V 35A (45A Peak) controllers (Model SH928-D5) for dual-wheel drive.

3. Individual Controller A (Front Motor) or Controller B (Rear Motor)
Replace a single damaged front or rear controller unit. Please verify your existing scooter has the matching SH928-D5 model before ordering.
4. Color LCD Display Throttle Unit
Original round LCD digital display with trigger accelerator and handlebar clamp.

Important Compatibility & Installation Notice
Critical Protocol Matching: The Obarter D5 uses matched communication between the throttle display and both controllers. If your scooter currently uses a different brand or revision of controller, replacing only one controller may trigger communication fault codes (Error 10 / Error 30). In that scenario, you must replace the complete system (Display + Controller A + Controller B) at the same time.
Frequently Asked Questions (FAQ)
Q: What is the difference between Controller A and Controller B?
A: Controller A is mapped to operate the Front motor wheel, while Controller B is mapped for the Rear motor wheel. They share communication with the display throttle to ensure perfectly balanced speed and torque across both wheels.
Q: Will this kit work with other 48V electric scooters?
A: This set is designed specifically as the OEM replacement for the Obarter D5. While the complete kit (Display + A + B) can technically power other dual-motor 48V scooters, connector wiring pinouts may need adaptation for non-Obarter frames.
Q: Why should I choose FOC Sine Wave controllers over standard square wave?
A: FOC (Field-Oriented Control) sine wave technology delivers smooth, progressive acceleration without the jerky off-the-line snap or loud electrical hum of square wave controllers. It runs cooler and maximizes battery efficiency.
Q: What warranty and transit support does E Smart Way offer?
A: All controllers and displays are bench-tested before dispatch. E Smart Way provides free worldwide shipping with door-to-door tracking, loss protection, and a 3-month replacement warranty on electronic components.
