Battery Disconnect Panel Black 2 Post

The Longacre Battery Disconnect Panel Black 2 Post is a rotary switch master disconnect designed to cut primary electrical power in vehicles equipped with dual-battery systems or high-amperage electrical demands. This aluminum-housed disconnect interrupts current instantly, making it essential safety equipment for automotive applications where rapid power shutdown is required—whether during maintenance, emergency situations, or prolonged storage.

Rated for 175 amps at 6–36 volts, this unit handles the electrical loads common in off-road vehicles, trucks with auxiliary electrical systems, or race cars with significant power draw. The two-post terminal configuration accommodates dual battery banks or split power circuits. The rotary switch mechanism provides positive on/off control with a clear mechanical detent—no guessing whether the disconnect is engaged. The black aluminum panel construction balances durability with weight savings, standard in professional-grade electrical control systems.

This disconnect serves off-road enthusiasts, race teams, automotive technicians, and vehicle builders who need reliable master power control. It prevents parasitic drain during storage, isolates batteries during repairs, and provides emergency shutdown capability. The compact 4.5 × 4.5 × 5-inch form factor fits most engine bays or battery box installations without consuming excessive space. Weighing just 1.12 pounds, it adds negligible mass while providing critical circuit protection and control.

Longacre, known for performance and safety electrical components, engineers this disconnect to automotive-grade standards. Battery disconnect panels are foundational to any serious automotive electrical system—controlling whether current flows at all is the first line of protection before any secondary fuse or relay.
