Simplify Your Flat Tow Setup with Wireless Battery Control
Flat towing your vehicle should be convenient and worry-free. The new Roadmaster Battery Ace Remote Battery Disconnect offers a modern, wireless solution designed to simplify battery isolation for dinghy towing and a wide range of 12-volt applications. At California RV Specialists, we are excited to offer professional installation and upgrades for this innovative product, helping RV owners enjoy a safer and more streamlined towing experience.
What Is the Battery Ace™?
Battery Ace™ is a next-generation, wireless battery disconnect system operated by a compact key fob. Unlike traditional battery disconnects that require routing wires through the engine compartment, drilling through the firewall, or installing dash-mounted switches, Battery Ace™ provides remote operation at the push of a button. This results in a faster, cleaner, and less invasive installation.
Designed primarily for flat towing (dinghy towing), the system ensures that the towed vehicle’s battery is safely disconnected, preventing unnecessary battery drain while traveling.

Why Use a Battery Disconnect for Flat Towing?
Many modern vehicles experience parasitic battery drain when towed due to onboard electronics such as steering locks, braking systems, and infotainment modules. A battery disconnect like Battery Ace™:
- Prevents a dead battery upon arrival.
- Protects sensitive vehicle electronics.
- Simplifies the towing preparation process.
- Enhances overall reliability and peace of mind.
Professional Installation at California RV Specialists
While Battery Ace™ is designed for straightforward installation, professional installation ensures proper fitment, safe operation, and seamless integration with your existing flat tow system.
At California RV Specialists, our experienced technicians specialize in:
- Flat tow system installations and upgrades.
- Tow bars, base plates, and supplemental braking systems.
- Electrical wiring and battery management solutions.
- Comprehensive system testing and customer demonstrations.
We also recommend verifying vehicle compatibility using Roadmaster’s Fitmaster tool before installation.
When to Choose the Heavy-Duty Option
If your tow vehicle is equipped with an 8-cylinder or diesel engine, the higher cold cranking amp (CCA) requirements necessitate a more robust solution. In these cases, the Roadmaster 767 Heavy-Duty Battery Disconnect provides the durability and performance needed for reliable operation.
