Description
The Roadmaster Battery Ace – Remote Battery Disconnect with Key Fobs is an innovative, wireless solution designed to simplify battery isolation for a variety of 12-volt applications, including flat towing. Unlike traditional systems, the Battery Ace eliminates the need for complex wiring, drilling, and panel modifications, reducing installation time and hassle for both professionals and DIY users. Operated by a compact key fob, this remote-controlled disconnect is ideal for towed vehicles, boats, RVs, trailers, and classic cars that experience battery drain during storage.
The Battery Ace is engineered with a unique safety feature: a Faraday pouch that blocks RF signals to prevent accidental activation while driving or when the fob is in use by passengers. The system also reduces parasitic power loss, extending battery life between uses.
Whether you’re towing a vehicle or storing a boat, the Battery Ace makes battery management easier and more reliable than ever before.
Please note: 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.
