Use The RUiXU 4AWG Cables For Reliable Power Transfer In Your 48V Battery Systems

When building or upgrading your energy storage system, the cables connecting your batteries to your inverter aren't just accessories they're the critical pathway for every watt of power.

The RUiXU 4AWG Cable with 5/16" Lugs and Pluggable Battery Pole Connector offers the perfect balance of conductivity, durability, and ease of installation for mid-range 48V systems, specifically designed to work seamlessly with the RUiXU RX-LFP48100 battery and RUiXU RX-LFP48100-H battery models.


RUiXU 4AWG Cables Features

Pure Copper Wire Delivers Maximum Power Without Energy Loss

Unlike cheaper aluminum cables, these use 100% pure copper throughout. Copper conducts electricity 60% better than aluminum, meaning less wasted energy, cooler operation, and more power reaching your devices when you need it most.

Factory-Installed Terminals Save You Time and Prevent Installation Mistakes

Both cable ends come professionally crimped and ready to connect. No special tools needed, no guessing if you did it right. Just bolt the ring lug to your inverter and plug the connector into your battery done in minutes.

Perfect Length Keeps Your Installation Clean and Professional Looking

At 6.5 feet long, these cables fit most battery-to-inverter setups perfectly. Long enough to reach comfortably, short enough to avoid messy excess wire. Your power system looks organized and works efficiently without unnecessary cable clutter everywhere.

Color-Coded Red and Black Design Prevents Dangerous Wiring Errors

Red for positive, black for negative—universal colors that make correct connections obvious. Even in tight spaces or low light, you'll never accidentally reverse polarity and damage your expensive inverter or batteries. Smart design saves costly mistakes.

Heavy-Duty Construction Handles Years of Demanding Daily Use Reliably

Built to withstand vibration, temperature changes, and constant power cycling. These cables maintain strong connections and full performance year after year without degrading.

Sized Right for Common Mid-Range Power Systems Up to 5,000W

The 4AWG thickness perfectly matches 48V systems running 2,000W to 5,000W inverters. Not too thin to cause voltage drops, not overly thick and hard to work with. Just right for most residential backup, RV, and off-grid applications.

Pluggable Battery Connector Makes Future Maintenance and Upgrades Simple

Need to disconnect your battery for service or system changes? The plug-style connector releases without tools, making maintenance quick and easy. Reconnecting is just as simple plug it back in and you're ready to go again.
