Ponzkoe 250A Smart Remote Battery Disconnect Switch – 12V/24V Kill Switch with Remote & Manual Button, LED Status

The Ponzkoe 250A Smart Remote Battery Disconnect Switch instantly isolates your vehicle battery with one remote tap or a manual press to prevent theft and stop parasitic drain.

Built for modern vehicles, trailers, ATVs and marine craft, this compact kill switch combines high-current copper contacts with a low-power control module so you can cut electrical feed without removing cables. It supports both 12V and 24V systems, offers a remote fob plus a manual on/off button, and includes visual LED feedback so you always know the switch state at a glance. The unit’s low standby draw helps preserve battery life during long storage periods while the rugged construction resists corrosion and false contacts.

How does the remote and manual control work?

Operate the switch from a distance using the included keychain remote or use the built-in button when you’re next to the vehicle. Five green LEDs clearly indicate whether circuit power is connected or disconnected, and an extendable external antenna improves remote range in open areas.

• Keychain remote for one-button open/close control
• Manual push-button for direct operation without the fob
• Five green LEDs for instant status confirmation
• Extendable black antenna to boost signal reach

Will this work with my 12V or 24V system?

The Ponzkoe switch is engineered for common automotive and marine voltages and adapts its behavior based on measured battery level. It functions normally across typical operating ranges and provides manual control even when voltage is low, but remote control is deliberately limited at low charge to avoid accidental cutoffs.

• Compatible operating windows: 11.4–14V and 23–27V
• Manual control available between 6.5V and 11V
• Below 6.5V the device will not operate
• Designed for 12V and 24V automotive and marine systems (not for industrial equipment)

How does it protect the battery and prevent false trips?

This model uses a smart low-current control board and robust copper switching contacts to reduce parasitic drain and resist intermittent connection problems. The ultra-low standby current preserves charge during storage, while upgraded accessories and anti-false-contact design keep the power path stable under vibration and changing conditions.

• Standby current ~0.7mA to minimize battery drain in storage
• High-quality copper contacts for long life and low resistance
• Anti-false-contact features to prevent accidental re-connection
• Includes improved mounting hardware for a secure install

What should I know before installing it?

Installation requires a suitable battery post diameter (15–17mm tapered) and secure fastening of all screws to ensure safe operation. The unit is intended for consumer vehicles, RVs, trailers, ATVs and boats — do not use it on industrial machinery. Avoid disassembling the device to protect the internal circuit board and follow torque guidance for a reliable connection.

• Fits tapered post diameter range: 15–17mm only
• Ensure all screws are tightened securely during installation
• Do not open the housing or alter the circuit board
• Not recommended for industrial equipment applications

Who is this for: Drivers, RV owners, boaters and small-fleet managers who want an easy, high-current way to isolate battery power for theft deterrence, long-term storage and wiring work. If you need a durable disconnect that offers remote convenience, clear visual status and minimal standby drain for 12V or 24V systems (within the specified voltage and post-size limits), the Ponzkoe 250A smart disconnect is designed to meet those needs while being straightforward to install and use.
