Product Description

Remote Battery Disconnect w/ Key Fobs

Battery Ace™ is a next-generation, wireless battery disconnect designed to simplify battery isolation for flat towing and a wide range of 12-volt applications. Operated by a compact key fob, Battery Ace eliminates the need to route wires through the engine compartment, drill through the firewall, mount dash switches, or modify interior panels. This streamlined design significantly reduces installation time and complexity for both professional installers and do-it-yourself users.

Unlike traditional battery disconnect systems, Battery Ace provides remote operation with the push of a button, making it ideal for towed vehicles that require battery disconnection during dinghy towing. Check out our Fitmaster for fitment.

A unique safety feature of Battery Ace is the included Faraday pouch for the key fob. The pouch blocks RF radio signals, preventing accidental activation while driving, or when the fob is handled by passengers. This shielding helps ensure reliable and intentional operation at all times.

While optimized for flat towing, Battery Ace is also well suited for classic cars, boats, trailers, RVs, and other 12-volt systems that experience battery drain during storage. By fully disconnecting the battery from vehicle electronics, Battery Ace helps reduce parasitic power loss and extend battery life between uses.

If your vehicle is a diesel, use Roadmaster's heavy-duty Battery Disconnect part number 767 instead. Diesel vehicle's have extremely high cold cranking amps and require a more industrial solution.
