Yosoo Health Gear 3/8" Thru-Panel Battery Terminal Studs, 2-Pc 250A Replacement Kit — Positive & Negative Heavy-Duty Marine/Auto

Two heavy-duty 3/8-inch thru-panel battery terminal studs that let you add or replace positive and negative posts for 250A battery circuits on cars, RVs, boats and yachts.

These Yosoo Health Gear replacement battery terminal connectors are compact thru-panel studs designed to create a secure junction through a bulkhead or battery box wall. Built for marine and automotive environments, each kit includes two 3/8" studs with backing hardware so you can install a terminal on either side of a panel without relying on the original battery clamp. They are intended for 250-amp circuits and for use where a clean, accessible battery post or distribution point is needed.

How do these thru-panel studs simplify battery connections?

They provide a tidy, bolted post that replaces messy or hard-to-reach battery clamp connections. By passing a threaded stud through the panel and locking it with nuts, you create a fixed connection point that accepts ring terminals or battery clamps on both ends.

• 3/8" threaded stud fits common ring/eyelet terminals.
• Comes with nuts and washers to lock the stud securely in place.
• Allows cable attachment on the accessible side; battery retained behind panel.
• Reduces wear on original battery terminals in tight compartments.

Are these studs durable enough for marine and automotive use?

The studs are manufactured for high-current applications and made to withstand vibration and humid conditions typical of cars, RVs and boats. Proper installation with stainless or corrosion-resistant hardware and sealing against moisture will help maintain long-term reliability.

• Rated for up to 250 amps — suitable for starter and accessory circuits.
• Robust threading and solid metal construction for vibration resistance.
• Use with anti-corrosion treatments or dielectric grease for marine exposure.
• Designed for thru-panel mounting to secure connections under load.

What hardware and wiring practices are recommended for safe installation?

Choose the correct wire gauge and ring terminal size for the 250A capacity, and make sure the panel hole is sized for a flush, solid fit. Tighten nuts to lock the stud without deforming terminals, and isolate nearby conductors to prevent accidental shorts.

• Use properly sized ring terminals that accept a 3/8" stud.
• Match wire gauge to circuit amperage (follow vehicle or vessel guidelines).
• Secure the stud with included nuts and consider thread-lock or sealant for marine use.
• Cover exposed conductive parts with boots or insulating caps for safety.

How will these studs fit my vehicle, RV or boat setup?

They are a flexible solution for applications where the battery is enclosed or where you want a remote distribution terminal. Because the studs pass through panels, they work well on battery boxes, bulkheads and control panels where space and accessibility are constraints.

• Ideal for boxed batteries in engine compartments or onboard battery lockers.
• Use as positive and negative remote points for accessory circuits.
• Compatible with standard 3/8" battery ring terminals and cable lugs.
• Can be used to retrofit older installations or add a convenient service point.

Who is this for: Technicians, DIY vehicle owners, boaters and RV enthusiasts who need a dependable, compact way to add or replace high-current battery posts. If you maintain starters, house-battery feeds or accessory circuits and want a secure thru-panel junction that handles up to 250 amps, these Yosoo Health Gear 3/8" studs provide a low-profile, serviceable solution that keeps battery wiring organized and accessible.
