Q: Can I use this S966-NFC display with any e-bike controller?
A: No. The S966 display uses Communication Protocol No. 2 and is specifically designed to communicate with JN-series Protocol 2 controllers. For optimal reliability and zero communication error codes, we strongly recommend purchasing the matched display and controller kit together.
Q: How does the NFC card unlock feature work?
A: When the bike is powered on, the screen remains locked and the throttle/PAS remain inactive until you tap the included NFC card against the designated icon on the screen. Once verified, the dashboard unlocks for normal operation.
Q: Which controller should I choose: 15A or 22A?
A: If your hub motor is rated for 250W or 350W, choose the 15A controller. If your motor is rated for 500W, choose the 22A controller to ensure sufficient current for acceleration and hill climbing.
Q: Are the connectors completely waterproof?
A: Yes. All signal and power lines feature high-grade molded waterproof circular plugs (WP) with internal rubber sealing rings, protecting your electronic connections from heavy rain and puddle splashes.
Q: What warranty and shipping terms are provided by E Smart Way?
A: E Smart Way offers free worldwide shipping with tracking and a comprehensive 3-month replacement warranty on all electronic accessories. All units undergo factory quality inspection prior to shipment.

I wanted to improve the electric bike, but the motor controller doesn't work and it ruined my grip throttle. The screen works but the setup instructions are horrible; there's no information on how to change the startup password. I'm considering whether to return the order.
