Description
Product Overview
End Game’s 4 gauge marine battery cable is engineered for the toughest power‑transfer tasks. Each conductor is made from tinned copper, providing superior corrosion resistance and long‑term conductivity. The cable features heavy‑duty, fully sealed 3/8″ or 5/16″ lugs that are pre‑tinned and crimped on a hydraulic press in the USA, ensuring a 100 % secure connection. PVC insulation is oil‑ and fuel‑resistant, while the outer jacket is heat‑resistant, weatherproof and waterproof, meeting UL and USCG standards and exceeding ABYC specifications. Available in single‑color (red or black) and matching red/black sets, the cable comes in lengths from 1 ft to 12 ft, covering a wide range of automotive, marine, solar and RV applications.
Usage
This cable excels in environments where reliability is non‑negotiable. Use it to upgrade battery connections on ATVs, golf carts, trucks, and cars, or for marine installations where exposure to saltwater and UV radiation is common. It is also perfect for solar charge controllers, RV and camper van conversions, and marine‑grade battery banks. The 157 A current rating and 60 V maximum voltage make it suitable for high‑draw applications such as starter motors, battery switches and auxiliary power units. Whether you are wiring a boat’s propulsion system, a solar array on a rooftop, or a high‑performance ATV, the End Game cable provides a secure, low‑resistance path for power.

FAQ
What gauge should I choose for my application?
For most marine, RV and solar installations a 4 gauge cable provides ample current capacity (up to 157 A) while keeping voltage drop low. If you need higher current capacity, consider a larger gauge; for low‑draw accessories, 6 gauge may be sufficient.
Are the lugs compatible with all battery posts?
Yes, the 3/8″ and 5/16″ lugs are designed to fit standard battery posts, battery switches and starter terminals found on cars, trucks, ATVs, golf carts and marine batteries.
Is this cable suitable for underwater use?
The outer jacket is waterproof and the lugs are fully sealed, making the cable safe for sub‑mersion in marine environments, provided the connections are properly insulated and protected from mechanical damage.
Can I use this cable for solar charge controllers?
Absolutely. The cable’s low resistance and high current rating make it ideal for connecting solar panels to charge controllers and battery banks, especially in off‑grid or RV setups.
What warranty does End Game offer?
All End Game marine battery cables come with a 100 % guarantee. If you encounter any defects or performance issues, contact our support team for a replacement or full refund.
