REC CAN Bus Cable for Victron GX Systems: Reliable BMS Communication

Purpose-Built CAN Bus Cable for REC 2Q BMS to Victron Integration

The REC CAN Bus cable provides a dependable connection between your REC 2Q BMS and Victron GX devices such as the Cerbo GX, Venus GX, or Color Control GX. This 3-metre cable is manufactured by REC to exact specifications, ensuring stable CAN-bus communication for your energy management system. Using a factory-assembled cable reduces the risk of intermittent faults, data errors, and connection dropouts that are common with improvised wiring.

At the BMS end, a Weipu SP13 5-pin circular connector provides a secure, moisture-resistant interface. The Victron end features an RJ45 8-pin connector wired to the standard Victron CAN-bus pinout: Pin 3 (GND), Pin 7 (CAN-H), Pin 8 (CAN-L). An additional RJ45 plug with a built-in 120-ohm termination resistor is included for proper end-of-line termination when required.

Why a Dedicated CAN Bus Cable Matters

CAN-bus networks rely on precise impedance matching and signal integrity. Handmade cables often introduce incorrect pinouts, poor shielding, or unreliable crimps, leading to communication errors that are difficult to diagnose. This REC cable is factory-tested to maintain consistent performance, helping you avoid troubleshooting headaches and system downtime. It is particularly suited for installations where the BMS and Victron GX device are mounted in separate enclosures or compartments.

Key Features

• Pre-assembled 3-metre CAN-bus cable for REC 2Q BMS to Victron GX systems
• Weipu SP13 circular connector for a secure, vibration-resistant BMS connection
• RJ45 connector with Victron-standard pinout (GND on Pin 3, CAN-H on Pin 7, CAN-L on Pin 8)
• Includes 120-ohm termination plug for proper CAN-bus end-of-line termination
• Manufactured by REC to ensure reliable signal integrity and long-term durability

Simplified Installation and Reliable Operation

This cable is designed for straightforward plug-and-play installation. The Weipu SP13 connector screws into place, preventing accidental disconnection in mobile or high-vibration environments such as marine vessels, RVs, and off-grid cabins. The RJ45 connector clicks securely into the Victron GX device's BMS-Can or VE-Can port. By using a cable built to the manufacturer's specifications, you reduce the risk of ground loops, incorrect termination, and signal reflection issues that can corrupt battery data.
