Get more charging power from your Sprinter's alternator while parked with the IOPEDAL High-Idle System.

The IOPEDAL High-Idle System allows you to increase your Mercedes-Benz Sprinter's engine idle speed in a controlled manner while the vehicle is stationary. Increasing engine RPM allows the alternator to provide additional charging output, making it especially useful for campervans and RVs equipped with large house battery banks and high-demand electrical systems.

This is a great option for Sprinter owners running high-output alternator charging systems where normal engine idle speed does not provide enough alternator output.

Features:

• Allows increased engine idle RPM while parked
• Helps increase alternator output at idle
• Ideal for charging larger campervan house battery systems
• Useful with high-output alternator charging systems
• Designed specifically for Mercedes-Benz Sprinter diesel engines
• Separate versions available for OM642 and OM654 engines
• Suitable for campervans, RVs, and off-grid electrical systems
• Controlled high-idle operation rather than manually holding the accelerator pedal

Why Use High Idle?

At normal idle speed, a Sprinter alternator may not produce its maximum available charging output. This becomes especially important when using:

• High-output alternators
• Large lithium battery banks
• High-amperage DC-to-DC charging systems
• Secondary alternator systems
• Electrical systems with large continuous loads

Increasing engine RPM while stationary can allow the alternator to operate at a more productive speed and provide additional charging power to the house battery system.
