REC DB9 to RJ45 CAN-Bus Cable: Reliable Communication Between REC BMS and Victron GX Devices

Purpose-Built CAN-Bus Cable for Seamless BMS Integration

The REC DB9 to RJ45 CAN-Bus Cable provides a direct, reliable link between your REC Active BMS or REC Q BMS and Victron GX devices such as the Cerbo GX, Venus GX, or Color Control GX. This cable enables real-time battery monitoring and control by transmitting CAN-bus data from the BMS to the Victron ecosystem, ensuring your energy storage system operates with precision and safety.

Engineered for compatibility with the REC BMS CAN-bus protocol, this cable supports both 500 kbit/s (Cerbo GX) and 250 kbit/s (other GX devices) data rates. It eliminates guesswork and custom wiring, reducing installation time and the risk of communication errors that can lead to system faults or battery damage.

Key Features

  • Plug-and-Play Connectivity: Pre-terminated DB9 female connector for the REC BMS CAN port and RJ45 connector for the Victron GX device, with no soldering or crimping required.
  • Integrated Termination: Includes a matched RJ45 termination plug with 120 Ohms across CANH and CANL, ensuring proper bus termination for stable communication.
  • Durable Construction: High-quality cable jacket resists abrasion and environmental stress, suitable for permanent installations in battery compartments or control cabinets.
  • Precision Wiring: DB9 pinout follows REC specifications: Pin 2 (CANL + termination), Pin 3 (GND), Pin 7 (CANH + termination), guaranteeing correct signal integrity.
  • Versatile Compatibility: Works with REC Active BMS (4 cells) and REC Q BMS (5-16 cells), covering a wide range of lithium battery configurations.

Why Proper CAN-Bus Cabling Matters

In a CAN-bus BMS system, the physical layer is critical. Poor-quality cables or incorrect termination can introduce signal reflections, data corruption, and intermittent communication dropouts. This REC cable is designed to meet the exact impedance and termination requirements of the Victron CAN-bus network, reducing the risk of BMS communication failures that could lead to overcharge, undercharge, or cell imbalance.

Unlike generic DB9-to-RJ45 adapters, this cable includes the necessary end-device termination resistor, which is often overlooked in DIY setups. Without proper termination, the CAN bus may become unreliable, especially in electrically noisy environments like engine bays or inverter compartments.

Installation Guidance

Connect the DB9 end to the CAN port on your REC BMS, and the RJ45 end to the BMS-Can port on a Cerbo GX, or the VE-Can port on other GX devices. Insert the supplied termination plug into the unused CAN socket on the GX device to complete the bus. For optimal performance, ensure the cable is routed away from high-current power cables to minimise electromagnetic interference.

This cable is specifically designed for REC BMS to Victron GX communication and is not intended for use with other BMS brands or non-Victron devices without verifying pinout compatibility.

Applications

  • Integrating REC BMS with Victron Cerbo GX for remote monitoring via VRM Portal
  • Enabling closed-loop communication between REC-managed lithium batteries and Victron inverter/chargers
  • Retrofitting existing battery systems with CAN-bus control for improved state-of-charge accuracy
  • Professional marine, RV, and off-grid solar installations requiring robust BMS data links

Get Connected with Confidence

Ensure your REC BMS and Victron GX device communicate flawlessly. Add the REC DB9 to RJ45 CAN-Bus Cable to your system today and benefit from reliable, real-time battery management data.

Better quality than the no-name brands
Size: 3 Pack, Color: Optic Yellow
I’ve played with quite a few different pickleballs over the past couple of years, including several cheaper “no-name” brands, and these Franklin X-40 balls consistently perform better for me. The biggest difference is durability. These seem to hold up much better to hard hits and regular outdoor play without cracking as quickly as many lower-cost balls I’ve tried. Even after multiple games, they maintain their shape and playability better than most bargain options. I also really like the bright optic yellow color. They’re easy to track during fast rallies and remain very visible in different lighting conditions, which makes a noticeable difference during competitive games. Performance-wise, they have a very consistent feel and bounce. There’s a reason these are used so widely in organized play and tournaments—they simply play reliably from game to game. While they may cost a little more than generic brands, I’ve actually found them to be a better value over time because they last longer and don’t need replacing nearly as often. Overall, these are my go-to outdoor pickleballs now. Durable, highly visible, and consistent on the court. Definitely worth it if you play regularly.

The Indispensable Standard for Outdoor Play
Size: 12 Pack, Color: Optic Yellow
As someone who genuinely lives on the pickleball court, having reliable equipment isn't a preference—it’s a necessity. The Franklin Sports X-40 Outdoor Pickleballs are the gold standard for a reason. From the moment you serve, the flight is true, offering predictable speed and a consistent, high-bounce off the court face, making every rally feel authentic and competitive. The 40 precision-drilled holes ensure that they cut through the wind effectively, minimizing drift on those breezy days that are inevitable in outdoor play. I’ve hit these with powerful serves and vicious third-shot drops, and they maintain their shape and integrity beautifully, far outlasting many other brands I’ve tried. However, let’s be honest about the one thing every dedicated player knows: you can never, ever have enough pickleballs. Even with the durability of the X-40, balls get lost in the bushes, occasionally crack under extreme force, or are simply needed for high-volume drilling. If you’re serious about the game, stocking up on these is essential—not just because they're great, but because having a full inventory is the only way to ensure the game never stops. If you’re looking for a ball that delivers official, tournament-level performance and holds up play after play, the X-40 is the one to get.

Bright, Smooth, and Worth the Price
Size: 12 Pack, Color: Optic Yellow
These pickleball balls are excellent quality and absolutely worth the price. I was hesitant at first because they cost a little more than other options for the same quantity, but the difference is obvious once you use them. They glide smoothly, feel like high‑end material, and the bright color is a huge plus especially in low lit areas where visibility can be an issue. They’re easy to spot on the court and stand out even when multiple games are going on. The color is noticeably brighter than most pickleballs I’ve seen, which makes them easy to identify and retrieve. The overall quality and size really speaks for itself. I highly recommend them.

Great Outdoor Pickleballs for Practice and Games
Size: 6 Pack, Color: Multi
These pickleballs have been great overall for outdoor play. The colors are bright and easy to see on the court, which is especially helpful during evening games or when playing on darker surfaces. They have a consistent bounce and feel durable compared to some cheaper pickleballs I’ve tried before. I also like that they fly pretty true and don’t wobble too much during rallies. They work well for both casual games and more competitive practice sessions. The balls feel solid off the paddle and provide a good balance of speed and control. The only reason I’m giving 4 stars instead of 5 is because a couple of the balls started showing small cracks after extended outdoor use on rough courts. They still lasted longer than many other brands, but I expected slightly better durability considering the price. They can also feel a bit harder than some softer outdoor balls, especially in colder weather. Overall though, these are reliable pickleballs and definitely a good choice for outdoor play. I’d buy them again for practice and recreational matches.
