EZKT Sine Wave Waterproof E-Bike Controller Kit
EZKT Sine Wave Waterproof E-Bike Controller Kit – Multi-Voltage 24V/36V/48V, High-Current 17A/26A/30A Options, Color S966 NFC Display & Julet Waterproof Cabling
Upgrade your electric bicycle or hub motor conversion with the EZKT Sine Wave Waterproof Controller Kit. Engineered for ultra-smooth power delivery, silent motor operation, and maximum efficiency, this controller utilizes advanced sine wave vector control to eliminate motor hum and harsh acceleration jerks found in traditional square-wave setups.
Designed for maximum flexibility across custom builds and replacement projects, the controller features auto-sensing 24V / 36V / 48V system compatibility and is available in 17A, 26A, and 30A current output configurations. Paired with a vibrant S966 Color LCD Display with NFC card unlock technology, this system delivers modern security, full-color telemetry, and sealed, weather-proof Julet waterproof quick-connect wiring.
⚠️ Wiring & Compatibility Guidance
PLUG-AND-PLAY WIRING & MOTOR MATCHING:
System Voltage: Supports 24V, 36V, or 48V nominal lithium battery architectures (auto-detects battery voltage).
Current Capacity Options: Select 17A (for 250W–500W motors), 26A (for 500W–750W motors), or 30A (for 750W–1000W+ motors).
Waterproof Quick-Connects: Features Julet waterproof cabling connectors (including 1T5 main bus harness, 9-pin/2-pin motor leads, and Hall sensor compatibility).
NFC Keyless Security: The included S966 Color Display requires swipe-to-unlock NFC card authorization to power on the bike system, serving as an effective digital anti-theft immobilizer.
