Throttle: QS-S4 LCD Trigger Finger Throttle (Colour LCD) - 72V for Zero 11X

This is the 72V version of the QS-S4 trigger throttle and LCD suitable for the Zero 11X

Connection Type: 6-pin round waterproof plug - MALE CONNECTOR.

USB Port

The QS-S4 also features a USB port that can supply 5V at around 500 mA to 1000 mA of current. It’s primarily intended for flashing the unit, but it could potentially be used for charging USB accessories though we do not advise it as current-thirsty USB devices risk frying your throttle unit.

1. Power on your scooter.
2. Hold the Mode + Power buttons (3-5 seconds) to access the P-setting menu.
3. Use the Mode button to toggle through P-settings.
4. Press the Power button to select the P-setting to adjust.
5. Press Mode button to increase the value, and Power button to decrease the value.
6. To save settings, allow the LCD to timeout (3-5 seconds) or long press Mode + Power buttons to exit the menu.

QS-S4 Error Codes

When the LCD controller detects an error, you’ll get the triangle and exclamation mark symbol, and it will display the fault code just above the battery life display.
