One-click protection for peace of mind

The Ponzkoe 250A Smart Remote Battery Disconnect Switch combines rugged reliability with convenient control. Designed for cars, boats, RVs, trucks, trailers, and ATVs, it lets you seal power with a single action while its tactile remote gives a satisfying click. The LED indicators provide instant feedback, so you’ll know the protection status at a glance even when you’re away from the vehicle.

Key advantages at a glance

• 1-Click protection up to 250A for rapid power cut
• Dual control: remote operation and a manual ON/OFF option
• Five bright LEDs confirm each action, reducing uncertainty
• Extended external antenna supports better remote range
• Ultra-low standby current helps preserve battery life during inactivity
• Premium copper construction with anti-false contact protection
• Broad compatibility with 12V and 24V electrical systems

Smart voltage guardian and reliable operation

The built-in voltage monitor guards your system while you focus on the task ahead. In smart mode, remote control is disabled below 11.4V to prevent unexpected shutdowns. Normal remote function occurs in the 11.4–14V and 23–27V ranges. If the battery falls below 6.5V, the device will not operate; for voltages between 6.5V and 11V, remote use is unavailable but manual control remains possible. Note: do not use this switch on industrial equipment.

Long-lasting performance for parked or remote assets

With an ultra-low standby current of 0.007mA, the unit sips power when not actively in use, helping preserve battery charge during long-term parking or storage. The copper construction strengthens durability and offers a stable, secure connection that can withstand vibrations and environmental exposure. The design also features anti-false contact protection to minimize nuisance interruptions.

Easy setup, flexible range, and practical use cases

The installation is supported by enhanced components for a secure fit. An extendable black antenna helps optimize remote distance in tight spaces or when vehicles are parked away from the main line of sight. This setup is well-suited for quick anti-theft power-off, aftercare removal of parasitic drain, or simple wiring changes where power isolation is beneficial.

Important notes for best results

• Ensure all screws are securely tightened during installation
• ONLY FITS POST DIAMETER RANGE: 15–17MM (TAPERED)!!!
• EXTEND external black string-shaped antenna for enhanced remote distance
• DO NOT DISASSEMBLE the device to avoid circuit damage

With its robust build, clear status indicators, and flexible control options, the Ponzkoe 250A Smart Remote Battery Disconnect Switch offers a practical way to manage power on the go—whether you’re protecting a parked fleet, a boat on shore power, or a weekend warrior’s ATV. Consider it as a possible, not guaranteed, enhancement to your vehicle’s power management toolkit.
