The V3 Controller includes several power-saving features that can significantly extend battery life between charges.

These settings reduce power consumption without affecting your connection to the Foil Drive system or normal riding performance.

This guide explains how to optimise your controller for maximum runtime.

Power Saving Features

The V3 Controller includes three settings that help reduce battery consumption:

• Screen Sleep
• Screen Brightness
• Auto Power Off

Using these features together can help maximise controller battery life, particularly during longer sessions.

Screen Sleep

What is Screen Sleep?

Screen Sleep turns only the display off after a short period of inactivity.

The controller itself remains fully powered on and connected to your Foil Drive.

As soon as you:

• Press any button, or
• Pull the throttle,

the screen immediately wakes up and continues operating normally.

Think of it like the screen saver on a computer—the display sleeps to save power while the controller continues working in the background.

Why should I enable Screen Sleep?

The display is one of the controller's largest power consumers.

Throughout a typical session there are many times when the controller isn't being used, such as:

• Walking to the beach
• Walking back from the water
• Resting between runs
• Waiting for waves
• Preparing your equipment

Allowing the screen to sleep during these periods helps extend controller battery life.

Foil Drive recommends enabling Screen Sleep for most riders.

Why is Screen Sleep turned off by default?

Screen Sleep is disabled from the factory to avoid confusion.

Without understanding the feature, some riders may think the controller has switched off or the battery has gone flat when the screen goes dark.

Once you're familiar with how it works, enabling Screen Sleep is recommended.

Screen Brightness

Does screen brightness affect battery life?

Yes.

Brighter screens require more power.

Reducing the display brightness lowers power consumption and increases controller runtime.

Which brightness setting should I use?

The best setting depends on the conditions.

• Low brightness – Maximum battery life.
• Medium (Level 3) – Recommended for most riding conditions.
• High brightness – Best for very bright sunny days where additional screen visibility is required.

If your priority is maximum controller runtime, use the lowest brightness that remains comfortable to read.

Auto Power Off

What is Auto Power Off?

Auto Power Off automatically switches the controller off after a period of inactivity.

If the controller is left on accidentally, this feature helps prevent unnecessary battery drain.

How do I configure Auto Power Off?

Navigate to:

Menu 14 – Auto Power Off

Select a timeout between:

• 1 minute
• 60 minutes

If no buttons are pressed and no throttle input is detected during the selected period, the controller powers itself off automatically.

What happens if the controller turns itself off?

Nothing is wrong.

Simply power the controller back on and continue riding.

Auto Power Off only activates after an extended period of inactivity.

Recommended Settings

Foil Drive recommends the following settings for most riders:

These settings provide an excellent balance between visibility, convenience and controller battery life.

Tips for Maximum Controller Runtime

For the longest possible battery life:

• Enable Screen Sleep.
• Reduce screen brightness where practical.
• Enable Auto Power Off if you occasionally forget to switch the controller off after riding.
• Turn the controller off manually once your session has finished.
• Recharge the controller before it becomes completely depleted.

Frequently Asked Questions

Does Screen Sleep disconnect the controller?

No.

Only the display turns off.

The controller remains powered on and connected to your Foil Drive.

Will touching the throttle wake the screen?

Yes.

Any button press or throttle input immediately wakes the display.

Does lowering brightness affect controller performance?

No.

Brightness only changes the display intensity.

It has no effect on throttle response, connectivity or motor performance.

Does Auto Power Off stop the controller while I'm riding?

No.

Auto Power Off only activates after the configured period with no controller interaction.

Normal riding continuously resets the timer.

Which setting saves the most battery?

The greatest improvements come from:

1. Enabling Screen Sleep.
2. Reducing screen brightness.
3. Using Auto Power Off to prevent the controller being accidentally left on after your session.
