OUKENS 3/8in Thru-Panel Battery Terminals 2-Pc Red & Black — 250A Brass Contacts, Sealed

When you need a clean, reliable way to route battery cables through a firewall, dash, or bulkhead, these OUKENS panel feed-thru posts provide a compact professional solution. Designed for automotive, marine, RV, and general power systems, the pair saves space, reduces wiring clutter, and makes accessory hookups easier without repeatedly opening the battery compartment.

How do these terminals simplify wiring through a panel?

The thru-panel design places the post on the exterior of the mounting surface while the connection hardware secures on the battery-side, creating a neat, solid pass-through. Installation requires only drilling a standard 3/8" (9.5 mm) hole and tightening the included hardware, so most DIYers can fit them quickly.

• Installs in a standard 3/8" panel hole for firewall or dash routing
• Color-coded red and black posts to prevent polarity mistakes
• Secures with threaded bulkhead hardware for a vibration-resistant connection

Are these connectors durable enough for marine or heavy-usage environments?

OUKENS uses wear-resistant brass contacts, a high-strength zinc alloy body, and a rubber seal to resist corrosion and wear. The materials and build quality are chosen to tolerate vibration, salt air, and frequent connections without degrading quickly.

• Brass contact surfaces for reliable conductivity and corrosion resistance
• Zinc alloy body and rubber sealing reduce wear and environmental exposure
• Professional anti-lock system prevents jamming under shock or misoperation

Can these terminals handle high current and multiple accessories?

Yes — each post is rated to carry currents up to 250 amps, making them suitable for high-draw accessories, starters, or distribution to accessory buses. While they handle significant load, always ensure cable sizes and fuses match your system requirements for safe operation.

• 250A rated for heavy-duty accessory and power requirements
• Accepts common 3/8" terminal fittings and lug sizes for easy integration
• Use appropriate fusing and cable gauge to match the connected load

What if I’m not a professional installer—how easy is setup and maintenance?

These connectors are designed for straightforward installation with no special tools beyond a drill and basic wrenches. The package includes one red positive and one black negative connector, and the visible color coding simplifies safe wiring. Routine checks for tightness and corrosion are all that’s needed to keep them working reliably.

• Easy DIY installation: drill, pass cable, and tighten the bulkhead nuts
• Clear red/black color coding for quick identification and safer wiring
• Simple maintenance: inspect seals and fasteners periodically

Who is this for? The OUKENS 3/8" remote thru-panel battery terminal pair is aimed at vehicle owners, boat builders, RVers, and technicians who want a tidy, dependable way to route battery power through walls or panels. It suits anyone fitting auxiliary accessories, creating remote battery access points, or replacing corroded feed-throughs — especially where compact, high-current, and corrosion-resistant connections matter. Verify your panel hole size (3/8" / 9.5 mm) before purchase for a proper fit and pair these posts with correctly sized cable and fusing for safe operation.
