OUKENS 3/8" Thru-Panel Battery Terminal Kit — 2-Piece Red & Black 250A Feed-Thru Posts, Brass/Zinc Sealed

When you need a clean, accessible battery connection on cars, RVs, boats or custom builds, these bulkhead terminal posts give you a dependable feed-through without the clutter of exposed cables. They mount in a standard 3/8" (9.5mm) panel hole and include a color-coded red positive and black negative post so you can quickly attach battery cables, grounding straps, or accessory feeds while keeping wiring tidy and protected.

How do these feed-thru terminals simplify wiring tasks?

These connectors bring battery access to the outside of a panel so you don’t have to run bulk cable around or through awkward routes. That makes installations faster, neater, and safer when routing power from a battery compartment to accessories, shore power systems, or remote devices.

• Mounts into a standard 3/8" (9.5mm) hole for consistent fitment
• One red positive and one black negative for instant polarity identification
• Keeps high-current leads consolidated and anchored at the firewall or bulkhead
• Reduces cable abrasion and potential short circuits by moving connections to the panel

What materials and safety features ensure long-term reliability?

OUKENS designed these posts from corrosion-resistant materials: wear-resistant brass conductors, high-strength zinc alloy housings, and durable rubber seals. A built-in anti-lock mechanism prevents accidental over-tightening or loosening, which helps maintain a consistent electrical connection under vibration and thermal cycling.

• Brass studs for sustained conductivity and corrosion resistance
• Zinc alloy housing for mechanical strength and durability
• Rubber sealing to block moisture and contaminants
• Anti-lock design to prevent jamming or sudden loosening

Can these terminals handle high-current applications and where can I use them?

Yes — each post is rated to handle currents up to 250A, suitable for many starter, inverter, and accessory circuits in vehicles and marine craft. They work well for automotive battery relocation, RV power panels, yacht shore power or accessory feed-throughs, and custom electrical enclosures where secure, high-current panel connections are required.

• Rated up to 250A for heavy loads and starter-type currents
• Compatible with battery cables and ring terminals sized for 3/8" studs
• Ideal for cars, trucks, RVs, boats, and off-grid power systems
• Useful for firewall, bulkhead, and equipment cabinet installations

How straightforward is installation and what’s included?

The kit includes one red positive and one black negative feed-thru post, each built for a 3/8" (9.5mm) panel hole. Installation requires basic hand tools: drill or verify hole size, insert the feed-thru, secure the nut, and tighten the stud connection; no specialist equipment or professional service is necessary for most DIY projects.

• Two connectors: red (positive) and black (negative)
• Fits 3/8" (9.5mm) panel holes — confirm hole size before mounting
• Simple hand-tool installation, torque to manufacturer guidance
• Designed for tidy cable routing and secure ring-terminal attachment

Who is this for: Installers, DIY mechanics, boat owners, RV enthusiasts, and system builders who need a compact, robust method to pass battery power through a bulkhead or panel. If you want cleaner wiring, reliable high-current connections, and easy battery access for maintenance or accessories, the OUKENS 3/8" thru-panel terminals are built to perform without complicated installation or frequent upkeep.
