Battery Thru Panel

The Battery Thru Panel is a heavy-duty bulkhead battery cable connector engineered for professional automotive, marine, and industrial electrical systems requiring reliable power distribution across panel walls or enclosure barriers. Designed for multi-voltage applications ranging from 6V to 48V systems, this connector enables technicians and installers to route battery cables through mounting surfaces while maintaining secure, weatherproof connections. Whether you're upgrading a custom vehicle electrical system, installing auxiliary power for performance equipment, or building a renewable energy setup, the Battery Thru Panel provides the mechanical integrity and electrical conductivity needed for mission-critical power routing.

This LONGACRE connector features solid brass construction, which resists corrosion and ensures superior conductivity across the full 6V–48V voltage range. The 1.25-inch diameter hole specification accommodates standard panel thicknesses, while the 3/8-16 inch stud provides robust mechanical fastening with included hardware for toolless assembly. The black finish offers both corrosion protection and professional appearance, and the bulkhead design eliminates the need for secondary sealing, reducing installation time and potential leak points. The compact 3.5 × 1.5 × 5.35-inch footprint makes it ideal for tight engine bays, battery boxes, and enclosed electrical compartments.

Installation is straightforward: position the connector through your pre-drilled 1.25-inch hole, secure with the 3/8-16 stud hardware (included), and connect battery cable lugs to the threaded posts. The Battery Thru Panel is ideal for race car builders, off-road vehicle fabricators, marine electrical technicians, and anyone upgrading high-output auxiliary systems that require isolated battery runs. Its multi-voltage rating ensures compatibility across 6V classic cars, 12V street rods, 24V heavy equipment, and 48V modern electric and hybrid platforms, making it a versatile single-product solution for diverse electrical architectures.
